Roller Coaster Temperatures Continue

March 9th, 2014 at 9:16 pm by under Weather

I hope everyone enjoyed the warmer weather this weekend! It was a perfect weekend for the McDonald Garden Show in Hampton too. I just want to say thank you to all of the nice people that stopped by the WAVY booth to say hi to me earlier this afternoon. If you bought plants and flowers at the garden show, you may want to wait a week to plant them. We could see temperatures dip below freezing by the end of the week.

The roller coaster temperature ride will continue this week. It will feel like spring Monday and Tuesday. Wednesday will be a transition day. Then winter returns Thursday and Friday. A trough (big dip in the jet stream) will begin to form out west as the next storm system starts developing. When this happens, we usually warm up as a ridge develops over us.

Highs on Monday will be in the mid/upper 60s and we should see temperatures around 70° on Tuesday. Unfortunately, all good things must come to an end. Wednesday will be our transition day, but still warm with highs in the 60s. Rain will move in during the afternoon ahead of our next cold front. With temperatures in the 60s, I wouldn’t be surprised if we saw a few thunderstorms develop. Cold front will move in during the early evening.

Computers models are hinting that we may see the rain change over to snow for some of us before ending all together early Thursday morning.

If we see any snow, it would only be for a very short time and we are not expecting any accumulation at this time. This all depends on if the cold air can move in before the moisture moves out. It is common for drier air to move in sooner than what the models show. In these cases, the precipitation usually ends before the cold air can really get locked into place. So right now, 3 days out, it looks like we may see a few snow showers behind the front. Stay tuned for updates. Cold weather returns for Thursday and Friday.

This is what the weather pattern will look like again Thursday and Friday. You may recognize this pattern by now because this is exactly what we have seen over the past 2-3 months. There has been a deep trough carved out over the eastern U.S. This helps keep the cold air in place across the east with warmer air trapped out west.

Lately, I have heard many Virginians say that this is one of the coldest winters they have ever experienced in Hampton Roads. After analyzing some data, I have come to the conclusion that this winter has been abnormally cold, but not the coldest on record. We have had a lot of extremes (cold and warm) this winter, which can balance each other out. Don’t get me wrong, we have seen many days where temperature didn’t crack 32° during the daytime hours. But we also set many new record highs. In December, we saw two 80° days! Here is the breakdown of each month with the temperature and precipitation data compared to average.

This Winter Compared to Average

This Winter Compared to Average For Norfolk

All of the high and low temperatures for each month are averaged out to a specific number. Then that number is either above or below average. The month of December was warmer than average, while January and February were colder than average. January 2014 was the 6th snowiest January on record with Norfolk seeing a total of 11.5″ of snow that month. The numbers show that this past winter has been colder and snowier than average, much different from just last year. The countdown to spring is on….only 11 more days!!!
