The frequency of days with severe weather continues to increase as we move into the more active months of the season, and after a long-tracked derecho knocked out power to over half a million customers in Pennsylvania last week, more storms are likely again Wednesday. We don’t expect anything to the magnitude of what we saw last week, but nonetheless the Storm Prediction Center has placed much of the state under a Slight Risk for Wednesday.
While the tornado threat looks to stay to our west tomorrow, damaging winds and hail cannot be ruled out especially in western and central PA. Storms will fire along the cold front late Wednesday afternoon and continue into the late evening hours thanks to ample instability.
FUTURE RADAR TIMING
Thunderstorms will begin to develop across the Bedford-Altoona-State College-Wellsboro region of Central PA late Wednesday afternoon and quickly strengthen. Below is Hi-Res NAM future radar for 5:00 PM Wednesday.
We do not expect storms to weaken much immediately after sunset, due to the hot temperatures that will be present. Storms will continue to move northeast after sunset into the Susquehanna Valley. Here is future radar for 11:00 PM Wednesday.
Any remaining storms will weaken to just showers after 2 AM Thursday.
SEVERE THUNDERSTORM OUTLOOK FOR WEDNESDAY
Area A: Scattered severe thunderstorms will be possible in this region late Wednesday afternoon into early morning Thursday. Damaging winds up to 60-70 MPH and hail up to 1″ in diameter are the main threats.
Area B: Isolated strong to severe thunderstorms are possible Wednesday evening.
