Issued at 342 PM EDT Wed Oct 1 2025
- Dry through the Weekend
Dry easterly flow goes southeast then south into the weekend with
modest moisture return by early next week. Upper ridging slowly
flattens over the next few days but temperatures return to the 80s
as the sfc high moves east and 850 mb temps are again around 15C
Friday through Sunday. A western CONUS trough advances east by
early next week.
- Chance of Rain Early Next Week
As the upper trough advances, a cold front will provide enough low
level convergence for some showers to move in late Monday, but
instability is limited and thunder chances appear to be low. The
front should move through by late Tuesday with surface high
pressure building in for Wednesday. Thursday morning could see
temperatures in the 30s with some frost/freeze conditions.
