.SHORT TERM... (Today through Wednesday night) Issued at 1107am CST Monday Nov 3 2025

High pressure extending from Kentucky south across the gulf south will maintain cool, clear and dry conditions both today and tomorrow. Lows Tuesday morning are expected to be a few degrees warmer than this morning with most areas starting the day in the 40s. The surface high will drift east off the east coast by Wednesday turning winds back out of the south which will pull tropical gulf air into the region initializing a trend of warmer temperatures and higher humidity Wednesday through the end of the week.

Long Term
(Thursday through Monday) Issued at 1107am CST Monday Nov 3 2025

Consistent southerly winds will push afternoon highs into the low to mid 80s Thursday through Saturday along with higher dewpoints in the 60s possibly touching the lower 70s Friday. A weak upper level disturbance will move across the region Friday which may interact with the higher moisture to produce a few showers or thunderstorms Friday.

Another cold front will push through the region Sunday morning accompanied by a few showers or thunderstorms. A significantly cooler airmass will filter into the region behind the front Sunday through early next week.

Marine
Issued at 1107am CST Monday Nov 3 2025

Fire Weather
Issued at 1107am CST Monday Nov 3 2025

Minimum RH values this afternoon and Tuesday will range from 25-35% along with light northerly winds. Winds will turn out of the south late Tuesday with both temperatures and humidity increasing Wednesday through the end of the week.
