Strong Storms Tonight (Midday Update)June 13th, 2013 at 9:48 am by Jeff Edmondson WAVY under Weather
Well here we go again, for the second time this week we have a risk for Severe Weather across Hampton Roads. If you remember on Monday we had severe storms move across Chesapeake and Virginia Beach. Those areas, as well as the entire viewing area have the chance to see some severe weather tonight.
We usually do not see too many moderate risk’s every year, usually 3-4 days, and that’s it. We need to stay Sky Aware this afternoon and especially when we could see these storms develop.
Heavy rain is likely, but the High Wind will be the biggest threat for tonight. The risk for large hail (1″/Golf Ball) is also possible with these storms. The tornado risk is low, but still present. The timing for these storms will still be late today, and close to sunset.
You can see hour-by-hour on what our Future Trak is thinking for tonight. We should see the development of these storms early towards Richmond. They could be moving at 40 and maybe up to 50mph to the East, similar to the line of storms this morning. This will keep the threat for damaging wind gusts high. Some have asked me if these storms are pushing in around 8pm will they be weaker since peak heating is done? Usually I would say yes, but since there is already so much heat/humidity available in the atmosphere they already have plenty of fuel to stay strong.
The mid levels of the atmosphere also look promising for severe weather. There is plenty of CAPE (Lift), Low CIN (Opposite force of CAPE), and we should also be able to reach the Convective Temperature of 93 degrees today. Conv. T is how warm we need to be to erase all of the CIN and allow the air to freely rise (creating clouds and storms). The shear should be high today for the development of storms, but the helicity and directional shear are lower which should help to inhibit a tornado outbreak. Isolated Tornadoes are still possible.
Stay sky aware this afternoon and evening. Meteorologist Tiffany Savona and Chief Meteorologist Don Slater will be in this evening to track the storms.
