SUMMARY…Thunderstorm coverage is expected to increase across the region over the next several hours ahead of a shortwave trough and attendant cold front. The airmass across the region is moist and unstable, with moderate to strong instability anticipated amid continued daytime heating. Vertical shear is modest, with a predominantly outflow-dominant storm mode anticipated. Given the expected updraft strength and ample moisture, some strong water-loaded downdrafts capable of producing wind damaging are possible.
The severe thunderstorm watch area is approximately along and 110 statute miles east and west of a line from 40 miles south southeast of Charlottesville VA to 40 miles northwest of Allentown PA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1).
PRECAUTIONARY/PREPAREDNESS ACTIONS…
REMEMBER…A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes.
