A Rainy End to AprilApril 28th, 2013 at 9:24 pm by Tiffany Savona WAVY under Weather
It was a beautiful weekend across Hampton Roads with highs in the mid/upper 60s both Saturday and Sunday. But we are tracking big changes in store for your Monday. The satellite/radar image that I captured at 8:30PM shows a very large storm system to our west.
The area of low pressure on the map is actually an upper level low, which will provide the energy for this storm system as it moves eastward. This upper low is going to be a very slow mover, not clearing Virginia until late Monday, early Tuesday morning. This is one of the reasons why we have rain chances in the forecast for the next few days. By just looking at the map, it seems like the rain has already moved into the region. However, a lot of the rain that is falling is evaporating before it hits the ground due to the drier lower levels of the atmosphere. Once the atmosphere moistens up, which should be closer to midnight, rain will begin to fall and reach the ground. Rain will become even more widespread overnight and into Monday morning. Check what our FutureTrak model is thinking for tomorrow’s morning commute.
You may want to leave yourself a little bit of extra travel time to get where you need to go on Monday. The rain should continue all day long and could be heavy at times. The rain and cloud cover will keep high temperatures in the mid/upper 60s. This storm system is going to be a big rain maker across Hampton Roads. Our latest computer model is saying that most areas could see 1-1.5″ of rain from now through Tuesday night.
The yellow and red colors indicate higher rain totals. A heavy rain band will likely set up somewhere in Hampton Roads. Wherever that rain band sets up, we could see isolated totals anywhere from 2-3 inches. I think 3 inches is on the high side, but not out of the question. Luckily, we do need the rain across Hampton Roads. The Norfolk International Airport is about 1.33″ below normal for the month of April. So this rain event should put us back on track.
One benefit of the heavy rain will be the decrease in pollen levels for at least the first half of the week. The rain should wash away a lot of pollens in the air. Pollen levels are forecast to be between 4-5 (Low-Moderate) on Monday, so allergy sufferers may see a little relief.
Make sure you bring the rain gear with you on Monday!
