Strong to Severe Storms Tonight
As Aaron mentioned yesterday, conditions are favorable for strong to potentially severe thunderstorms this evening and overnight in Central Virginia. A broad upper trough is approaching the East Coast today, with a strong surface cold front tracking east with showers and thunderstorms along and ahead of this front. Early Thursday morning, the cold front is tracking through central Kentucky, Tennessee, and Alabama. Once this front reaches western Virginia this evening, rain will start out west by 6 p.m. and reach areas east of I-95 by 11 p.m. A squall line will likely develop with frequent lightning, strong wind gusts, heavy rainfall, and potentially some hail. The risk for tornadoes is extremely low, but an isolated spinup could occur.

Severe Threat Thursday
A front will arrive in our area tomorrow evening and bring us a good chance for thunderstorms. Thunderstorms will start popping west of I-95 between 5 and 8 PM. Scattered thunderstorms will then overspread central Virginia from 8 PM to 4 AM.
I think the computer forecasts are keeping our high temperatures too low. With partly cloudy skies for the first half of the day, we should easily climb into the upper 80s. That means our atmosphere will be more unstable than what is currently depicted by the computers.
Jet stream winds will be strong, so there will be plenty of speed shear. Winds will be southwesterly from the ground all the way into the upper atmosphere. This means that damaging winds will be the primary threat tomorrow. An isolated short-lived tornado could develop within the strongest storms, however, once the storms form into a squall line, the threat for tornadoes will decrease.
