An area of low pressure moving into the Appalachians will bring widespread showers and thunderstorms into Halloween. Tonight, we’ll see scattered showers (becoming very spotty after midnight), mainly cloudy skies, and lows holding in the upper 50s/low 60s. We’ll get breezy overnight as well, and with winds coming out of the south, we’ll feel Spring-like into tomorrow.
Thursday will bring off-and-on rounds of showers and thunderstorms throughout the day, but especially during the afternoon and evening as the cold front part of this system swings through the area. With warmer than average temps tomorrow in the upper 60s/low 70s Thursday afternoon, we’ll have enough energy in place for a few possible severe thunderstorms tomorrow afternoon/early evening.
The main severe weather threats will be heavy rain and gusty winds. With 1-2″+ of rain possible across most of the area, localized flooding issues could arise, especially in poor drainage areas. Gusts at times tomorrow could range from 30mph to 50mph, and winds tomorrow could get briefly higher in any thunderstorms. Of lesser concern, but NOT OUT OF THE QUESTION, will be the small chance of a rotation/brief tornadoes and isolated hail tomorrow afternoon. Sporadic power outages and downed trees/limbs cannot be ruled out on Halloween.
Thursday night will remain windy behind the departing front, but with winds switching directions out of the north, we’ll be much colder. Though the chance and coverage of precipitation will be much less late Halloween night, any lingering rain could mix with snow/flurries into early Friday morning as lows fall into the 30s. We look much drier, but chilly into the first few days of November. Stay tuned!
