Fog And Bouncing Temps

December 3rd, 2014 at 8:32 am by under Weather

We had some pretty thick fog this morning in the region. In fact there was a pretty long list of school delays.  Moisture pushed into the region which was already covered by a cool air mass. So there was ample fog and clouds to start the day.  We even had a couple of sprinkles as well.

The warm front will lift north today.  Once it moves through, then we’ll start clearing out and warming up.  We’ll have highs in the upper 50s to low 60s this afternoon. Winds will be out of the southwest.

Then…by tonight another cold front will move through Hampton Roads.  This will give us another hum-dinger cool-down.  Tomorrow we’ll only see highs in the upper 40s with a few 50s over North Carolina.  Ughhh!  We’ll steady out the temperatures then as we go into the weekend.  Highs will stay in the 50s.  There is still a chance for rain late Saturday into Saturday night.  Some of the rain could linger into Sunday morning. It’s hard to say when it will actually push out.  Stay tuned for updates!

In national news….a new article from Scientific American talks about a detailed study concerning urban heat islands from the University of Wisconsin in Madison.  It found that “…the density of urban development and lack of vegetation had the greatest impact on temperature variation”.  Here is the article: Urban Heat Island Study.  There’s something to think about on the colder days.

Wow! What A Change!

December 2nd, 2014 at 9:00 am by under Weather

I was out in shorts yesterday enjoying the warm/fresh air.  I had to trim some bushes to get them ready for the Christmas lights.  I made sure to do it yesterday, because I knew that I wouldn’t want to be outside today.  The high temperature at Norfolk International Airport was 74 degrees Monday afternoon.  Today we are only going for highs in the 40s to near 50.  This is due to the cold front that moved through the region last night.  Today it will stall out to our south.  Behind it the surface winds will keep on coming out of the northeast.  They will run at 10-20mph.  So the cold air will continue to pour in.  Meanwhile in the upper levels the winds will be out of the southwest.

Warm Air Overruns Cold Air

Warm Air Overruns Cold Air

This is called an overrunning weather pattern.  Basically the warm/moist air will move north and condense as it hits the cooler air.  This will keep the clouds thick, and will also create some drizzle and isolated showers.  By tonight the front will move back north as a warm front.  We’ll probably bottom out in the low 40s, but then temps will rise overnight.  Patchy fog will be possible by Wednesday morning.  Then by midday tomorrow we’ll be looking good.  We’ll go to partly sunny skies with temps in the 50s.  We’ll top out in the 60s or near 60 in the afternoon with fair skies.

Another cold front will move through Wednesday night, and will cool us down into the weekend.  Highs will be in the 50s for several days.  The next decent chance for rain looks like it will be on Saturday now.  Stay tuned for updates.

Cyber Monday Weather

December 1st, 2014 at 8:34 am by under Weather

I’m not sure…but I don’t think this is good weather for cyber Monday.  Oh don’t get me wrong…the weather will be absolutely great outside.  So great that many will want to look out their window and forget about looking at their laptops.  Maybe they’ll take their tablets outside and try to order.  But the waft of fresh air will take them away from their holiday deal hunting.  At least for a moment.  For everyone else this is going to be a nice warm day.  On that note…temperatures in November have been all over the place.  Take a look a the high temperatures for the last 30 days:

High Temps In November

High Temps In November

Notice the large/sharp spikes in temps into the 70s, then the huge drops that followed.  It would then stay chilly for 2-4 days in a row.  We are looking at the same thing again.  Yesterday we topped off at 68 degrees at Norfolk International Airport.  Today we are going for highs near 70.  Maybe even the low 70s.  This is due to lots of sunshine and a southwest breeze.

Satellite/Radar

Satellite/Radar

High pressure is edging offshore, but it will close enough to continue our sunshine.  The cold front in the picture above will swoop into the region by this evening.  We’ll see some spotty showers along the front.  Temperatures will drop to the upper 40s tonight.  Then tomorrow the temperatures will be stuck in the upper 40s.  The front will slowly come to a halt over North Carolina. We’ll see some scattered showers in the region.  The models don’t show too much rain for tomorrow, but I believe we’ll see at least some drizzle or sprinkles for a good bit of the day.  This will be due to the warmer/moisture air already trying to make a comeback from the south.  So we’ll start warming up by Tuesday night.  By Wednesday we’ll rise back up to near 60.

The temperatures will steady-out by the end of the week.  Highs will stay in the 50s for a while.

Hurricane Season Ends Today

November 30th, 2014 at 9:05 am by under Weather

The 2014 Hurricane Season comes to a close today. This was another quiet year for the Atlantic Basin. The two notable storms were Arthur which impacted the Outer Banks and Gonzalo that impacted Bermuda.

Hurricane Tracks

Hurricane Names

Hurricane Names

Hurricane Arthur came on land as a Category 2 storm with sustained winds over 110 mph. This storm made landfall just after midnight on the morning on July 4th. Check out my blog from that morning. The storm didn’t cause major damage to the OBX since it was moving quickly to the northeast. The movement of the storm was just over 20mph which reduced the chances for significant storm surge.

The other storm of the season was Hurricane Gonzalo. This was a category 4 hurricane with sustained winds at 145mph at its strongest point. This storm resulted in fatalities and severe damage across Bermuda. This storm was also moving quickly to the north when it hit the island so the overall damage was lower than it could have been. Estimates say that over $200 million of damage was caused by this storm.

As we go into December, hurricanes and tropical storms are rare. One of the strongest storms in December made landfall in Florida on the 1st. It moved on land as a tropical storm. This occurred in 1925. Tropical Storm Odette hit the Dominican Republic around December 5th & 6th in 2003. Storms have a difficult time developing by December because the sea surface temperatures are colder.

Current Sea Surface Temperatures

Current Sea Surface Temperatures

You need temperatures at or above 80 degrees for development of these tropical systems. Since we have had so many blasts of colder air, the water temperatures off our coast and down the our south will stay too cool for development of storms. The only storms we need to watch out for are Nor’Easters.

The reason why this year was so quiet was from a few different factors:

  • Shear (Speed Shear Mostly): Remember, speed shear is the change in wind speed with height. Hurricane need a low shear environment to develop.
  • Lack of Energy from the African Continent: A weak monsoon season prevented waves of energy moving over the Ocean.

So for now, we can put our hurricane guides aside and prepare for winter. Meteorological Winter begins tomorrow on December 1st!

Sunday Travel Weather

November 29th, 2014 at 8:46 pm by under Weather

I hope everyone had a great Thanksgiving! Some of you may be traveling home tomorrow after a long holiday weekend. The weather is looking good if you plan to travel across Virginia or North Carolina. Expect lots of sunshine with highs in the 60s. Don’t forget the sunglasses!

Regional Travel Map

Regional Travel Map

If you are flying tomorrow, you shouldn’t run into too many problems. The East Coast is looking dry. Light rain is possible across the Ohio River Valley. Accumulating snow is possible across Montana and Wyoming, so you may have some delays there. Rain is likely for northern California, which is a good thing. Any rain that falls in California will help with the exceptional drought still going on across much of the state.

National Travel Map - Sunday

National Travel Map – Sunday

Our local weather across Hampton Roads and North Carolina is looking great for the last day of November. High pressure is located offshore, so winds will shift more out of the southwest tonight, keeping temperatures in the upper 30s and lower 40s. Some inland spots may see temperatures drop into the mid 30s by tomorrow morning. Breezy southwest winds will help boost high temperatures into the low to mid 60s Sunday afternoon.  If you want to put up outdoor holiday lights, tomorrow will be a great day to do that.

Sunday Planner

Sunday Planner

Our next cold front will move in Monday night, so Monday afternoon will still be warm with highs in the mid to upper 60s. Cooler air will move in behind the front and rain chances will go up on Tuesday. Highs on Tuesday will only be in the upper 40s.

***The 2014 Atlantic Hurricane Season ends tomorrow. Sunday’s blog will have a full recap of the season.

Safe travels everyone!

Chilly Today, Warming Up Tomorrow

November 28th, 2014 at 9:52 am by under Weather

We started this morning with temperatures in the 20s and 30s. This day after Thanksgiving will be colder for shoppers as our highs will only in the 40s this afternoon. Remember, the average high is 57 degrees for this time of year. Tomorrow will be a little warmer as a warm airmass moves in from Texas.

Warming Trend

Warming Trend

Our temperatures will continue to warm up this weekend. With the warmer air moving in tomorrow we may see a few extra clouds in the afternoon. No rain is expected from this warmup. That area of high pressure is pushing in a very dry airmass right now which will take several days to moisten and produce rainfall. On Sunday, we will be sunny with highs near 64 degrees in the afternoon. Our next shot of rain doesn’t come until next week Tuesday.

Have a great Holiday Weekend!

Really? A Thanksgiving Blog??

November 27th, 2014 at 6:37 am by under Weather

Yep!  Normally I would take the holiday off and give my typing hands a break for Thanksgiving.  But NO!  I’m toughing it out for the sake of weather.  Ok, I’m being dramatic, but it’s sorta true.  For this Thanksgiving we are looking at some wet weather in the region.  Scattered showers will be falling today.   It won’t be like yesterday with the heavy rain and gusty winds, but rain is in the forecast.  This is coming from a weak disturbance that is riding out of the Tennessee Valley and into the Mid-Atlantic.

Satellite/Radar

Satellite/Radar

As the system moves east it will encounter warmer temperatures.   So a lot of the region will see scattered rain showers.

Travel Forecast

Travel Forecast

There will also be scattered snow showers over the Appalachians, but it shouldn’t be as heavy as yesterday.  While the surface temperatures will be in the upper 30s to low/mid 40s in our region, the temperatures aloft will be well below freezing.  The freezing level will be at about 2-3,000 ft.

Wintry Mix Explained

Wintry Mix Explained

So there will be snow in the mid-upper levels, but it is likely going to melt as it travels through the bottom 3,000ft.  Sometimes though, if the precipitation gets heavy, then the cold air can get dragged down to the surface.  This is possible today.  So that will allow for some sleet (partially melted snow) and wet snowflakes to mix in with the rain at times.  With temperatures above freezing it should all melt.  But don’t be surprised if you head outside and see a little brief snow.  This all pushes out by tonight. Lows will drop to the 30s.  Then we’ll see dry weather for the rest of the weekend.  It will be chilly tomorrow. Highs will be in the low 40s.  Then we’ll be in the 50s on Saturday and 60s on Sunday.

Hope you have a nice holiday.  Safe travels!

Nor’easter Hurts Travel!

November 26th, 2014 at 8:33 am by under Weather

It’s a rough go this morning.  Whether you’re a commuter or a traveler , you are going to have to take it slow today.  We’ve had widespread rain since the overnight.

Local Satellite/Radar

Local Satellite/Radar

The rain has been heavy at times. So far we’ve picked up about a half inch to an inch.  The rain is continuing to add up.  The reason we have this rain is due to an area of low pressure that is creeping north along a stationary front.  This is happening offshore.   The system is becoming a weak nor’easter.

Nor'easter Developing

Nor’easter Developing

There is a lot of moisture being thrown back to the west.  This moist air mass is hitting a colder air mass to our west. This is creating snow showers over the Appalachians already.  Snow will be a problem for folks traveling to the west or the north.  Anyone crossing the regional mountains will have to be very careful today.  Winter storm warnings affect a large area.  Some locations will see 3-6″.

Winter Storm Warnings/Advisories

Winter Storm Warnings/Advisories

Our local area will be too warm for snow today, but the rain will plague anyone driving across the region.

Travel Forecast

Travel Forecast

Actually along the entire east coast there will be problems with travel.  There will also be some snow showers from Minneapolis down to St. Louis.
The southwestern U.S. is the place to be today.

U.S. Travel Today

U.S. Travel Today

Fur us, the rain will be widespread through the mid afternoon.  Between 3-5pm the showers will become more scattered.  We aren’t expecting thunderstorms, but we will likely see 2-3″ of rain.

Forecast Rain Totals

Forecast Rain Totals

Ponding on roads will be very common as well as some localized flooding.  This will especially be a problem around tidal areas.  While the tidal flooding isn’t expected to be too bad (mostly nuisance), the problem is a newly common one.  When the tide comes up during big rain events, the rain doesn’t drain very well.  So you get minor tidal flooding even when nuisance is forecast.  This will mostly be along the southern Chesapeake Bay.  Here is the tidal forecast for Sewell’s Point.

Tide Forecast

Tide Forecast

This tidal rise of about 1-1.5 ft above normal will come around the midday hours.

Rain will finally come to an end by this evening.  Unfortunately, another system will impact the area tomorrow.  The nor’easter will be long gone, but a weak upper level disturbance and a small push of colder air will move into the region.  Scattered rain showers are expected from the late morning through the mid afternoon.

Future Trak (Noon Tomorrow)

Future Trak (Noon Tomorrow)

The precipitation should be light.  Keep in mind that it will be below freezing up just a couple thousand feet while temps will be in the low-mid 40s at the surface.  So I would expect some wet snowflakes and sleet pellets mixing in with the light rain showers.  Nothing should stick though as the surface will be too warm.  We should dry up by the time we get to Thanksgiving dinner.

After that we’ll have a nice dry period.  It will be cold and dry for Black Friday.  Lows will be in the 30s and highs in the 40s.  Then we’ll warm up for the weekend.  Highs will be in the 50s on Saturday and 60s on Sunday.  At least folks that are traveling will have some nice weather this weekend.  It will be nice for shopping and decorating as well.

Good luck in your travels out there.  Try to allow plenty of time to reach your destination.  Also, check your flights and your routes.

Holiday Travel Mess Ahead

November 25th, 2014 at 8:50 am by under Weather

The weather is going to be pretty tough for travelers over the next couple of days.  If you are driving out of town or have a loved one coming in, then you will want to continue to monitor the weather.  We’ve already had scattered showers out there today.  This is from a lot of moisture pooling in ahead of a cold front.

Satellite/Radar

Satellite/Radar

The cold front is closing in from the west.  We started with a very warm and humid morning. Temps were mostly in the 60s.  As the front passes the winds will turn from southwest to out of the northeast.  This will drop temperatures to the 50s this afternoon. We’ll be in the low 50s by the evening.  The scattered showers will continue on and off through the afternoon.

Today"s Forecast

Today”s Forecast

The front will push offshore through the evening. However, it is forecast to stall out over the ocean.  An area of low pressure will form along the front and move northward tomorrow.  This will push the moisture back to the west.  So rain is likely for most of the day and most of the region.

Tomorrow's Forecast

Tomorrow’s Forecast

Rain will be heavy at times.  We are looking about about 1-2 inches of rain for our region with higher amounts possible.  If you are traveling south, west, or north you’ll hit at least some rain.

Regional Travel Map

Regional Travel Map

This will be there in the early morning.  So don’t expect to head out early to beat the weather.  It should taper off later in the day as the low begins to move away.  Snow is possible over the Appalachians tomorrow.  So keep that in mind if you are going to travel out that way.  This will impact cities like Blacksburg, Charlottesville, and Staunton.

We’ll dry things out a bit by tomorrow night.  However, another pocket of moisture and an upper level disturbance will move through Thursday morning.  This will bring us some scattered showers.  It’s possible that sleet pellets and/or wet snowflakes will mix in with the rain.  Even if that happens though, nothing should stick to the ground.  Temps will be above freezing.  According to the National Weather Service, there have only be 3 Thanksgivings with snow.  The latest one was in 1912 with 0.5″ of snow on the ground.

We will dry out by Thursday evening.  Highs will be in the 40s.  We’ll be dry and chilly on Friday for the big sales.  Highs will be in the 40s.  At least we’ll be dry and warmer over the weekend.  So that let of the journey will be good for travel.
