Tuesday’s Severe Weather ThreatApril 15th, 2014 at 9:29 am by Tiffany Savona WAVY under Weather
Before, we get to the severe weather threat today, I want to show a picture of the Lunar Eclipse. If you were lucky, like me, there may have been enough breaks in the clouds for you to see the moon. Stephen Gagnon captured this beautiful picture in Carrollton this morning.
We are tracking a strong cold front that will move through Hampton Roads early this evening. Before the front moves in, a line of showers and storms will develop. Some of these storms could turn strong to severe. The Storm Prediction Center has highlighted our entire area in a slight risk for severe weather this afternoon.
The main severe weather threats will be heavy rain and damaging winds in excess of 60mph. Tornado threat is low, but not zero. If we see an area of low pressure develop along the front, we could see an enhanced tornado threat just south of the low. One computer model has the low developing across NE North Carolina, while another model has the low developing across SE Virginia. A couple other models do not have an area of low pressure developing at all. This is something we will be watching for this afternoon. Keep in mind that if we see more rain this morning, then the severe weather threat will be lower. If we see more sunshine, then the severe weather threat will be going up this afternoon. The window for seeing severe weather will be between 3-9 PM, ahead of the cold front. The line of showers and storms should move through the metro area around 4-7 PM. This means we are looking at a messy evening commute. Any thunderstorm that can develop ahead of the front could be strong to severe. Here is what our Future Trak computer model has at 5 PM.
Once the front clears the area, the severe threat will be gone. But the rain will continue behind the front and the rain could be heavy at times. Here is what our Future Trak model has at 9 PM.
Winds will turn northerly behind the front and increase in speed. Look for sustained wind speeds between 25-35 mph with gusts ranging from 40-45mph overnight. Much colder air will filter in and temperatures will drop into the mid 30s by Wednesday morning. Wind chill values will be in the 20s!!! Welcome back winter! Future Trak Temperatures has lows around 32° for our northern and western counties with mid 30s everywhere else. Record low for Norfolk Airport is 33° set back in 1943, so we will be close.
The National Weather Service issued a Freeze Watch in effect for all counties highlighted in blue. These areas could see temperatures dip below 32° for a couple of hours overnight.
If you live in these areas, make sure you bring any potted plants indoors and/or cover any sensitive vegetation.
Good news for all of the allergy sufferers…the pollen forecast is LOW today due to the rain and the wind. The heavy rain should really knock down the pollen count today. I will be tracking the potential for strong to severe storms this afternoon. Stay with wavy.com for the latest.
