Cold Front, Tropics…Ay Caramba!

(10:45am update:  Tropical Depression 4 has become tropical storm Dorian with winds near 50mph.  Here’s the latest info from the National Hurricane Center: Dorian. See blog below for more on the local forecast.)

Ok!  Here we go again.  We’ve had some pretty active weather lately with the flooding and the lightning strikes.  Now we have a big cold front to contend with and a new system in the tropics. Let’s talk about it:

This morning we had partly cloudy skies and no rain.  Temperatures were pretty standard in the 70s, and the humidity was still high.

There were some showers and storms over West Virginia which was closer to the cold front.  The front will approach Hampton Roads from the northwest later today.  It will create scattered showers and storms.

We are not in a slight risk for severe weather, but we could see a few strong storms during the peak heating of the day.  Along with ample heat and humidity, there will also be a little upper level wind support.

Highs will be near 90 around the midday hours.  Then we’ll pull the temps back a bit to the low/mid 80s for most of the area.  However, it will probably stay hot over North Carolina as the front won’t clear there until tonight.

Tonight the front won’t necessarily get hung up, but it will slow down right over our region.  This will allow for a band of heavy rain to form right along the coast.  This could include the metro  area. That would cause a lot of problems for the morning commute.  Stay tuned on that!

The front will move south of us during the late morning, but some showers will still be possible through the afternoon.  Either way the temperatures look much cooler.  Highs will be in the low 80s, and some computer models even put in some upper 70s over the region.  Nice!  The cooler air looks to stick around on Friday, and we’ll dry out then.  Saturday looks warmer, but there will only be a slim chance for a shower.  Scattered storms are expected late Sunday into Monday.
More on that as it gets closer.

In the tropics we have newly formed tropical depression #4.  The satellite looks fairly impressive, as the cloud tops have shot up over the last couple of hours.

So this will probably be upgraded to a tropical storm in the next update.  It may already be one physically.  There is a pretty high confidence in the forecast track.  It is currently moving WNW at 20mph.  It has winds of 35mph, and it is forecast to strengthen. However, it will also be moving over an area that is not as favorable for further development. So that may stop it from getting too strong. By Monday the storm looks to approach the Puerto Rico area.

We’ll be tracking this system over the next few days.  It is going to ride south of an area of high pressure (Bermuda High).  Towards the end of the forecast there is a small possibility for it to move more to the north.  For now though it is just something to watch.
