A severe weather threat this afternoon!
April 20th, 2009 at 12:45 pm by Jon Cash under Weather
A cold front will be approaching the region late today into this evening. Some storms could turn severe with this and here are the reasons….
1. A jetstream of 75 mph above the surface
2. Dew points rising into the mid to upper 60s…this is the moisture needed to help the air lift and form clouds
3. Temps well into the 70s also adds to the instability which should help the storms pop during a couple of hours after maximum heating
4. An upper level disturbance (cool pool of air at the jetstream level) that helps the temperature difference between the surface and 10 to 20 thousand feet increase
5. The cold front itself…a good location for the storms to line up
There doesn’t appear to be alot of helicity (spin) in the atmosphere with this so the primary threats should be hail and strong gusty winds…stay tuned!

There was a downpour in Norfolk (near the airport) which lasted about 5-10 minutes. The downpour also included peanut-sized hail.
Pea size hail in Portsmouth last 10 min
Why does any weahter event in the area get coverage like it’s a life ending event. You guys cry wolf at any weather event, when something actually happens life threating nobody will listen!!!!
Please…. enough! we have seen the weather for 20 min. repeating the same thing! Got it! Start the show!
I was just wondering why there was not a story on the accidents on 64 west yesterday around 6:15pm. I counted 11 accidents between the highway 17 exit and the other side of the high rise bridge. There were police and emergency vehicles everywhere….
