.SHORT TERM... (Tuesday through Wednesday night) Issued at 203pm EDT Monday Mar 18 2024

High pressure conditions will be in place through the middle of the week with dry weather, mostly clear skies, and predominantly mild winds persisting through Wednesday. There is a possibility for frost formation early Wednesday morning for some areas however conditions for development are borderline so confidence at this time is low. Coolest temperatures for the week will be on Tuesday with high temperatures in the lower to mid 60s on Tuesday and rising into the lower 70s Wednesday. Overnight low temperatures will similarly rise from out of the upper 30s up into the mid 40s Wednesday night going into early Thursday morning.

Long Term
(Thursday through next Monday) Issued at 203pm EDT Monday Mar 18 2024

The influence of high pressure will diminish and move off to the east on Thursday with chances for showers and thunderstorms increasing on Friday as instability associated with a low pressure system traveling across the Gulf of Mexico and then being followed by a dry front bringing high pressure conditions over the forecast area by the end of the weekend. Temperatures will drop to be slightly below the seasonal average by the end of the week but will return to normal levels by the end of the weekend.

Marine
Issued at 203pm EDT Monday Mar 18 2024

A cold front and wave of low pressure will continue to move across the area today with scattered to numerous showers through the afternoon and into the evening. In the wake of the cold front, a rapid increase in northwest to north winds is expected tonight and will support gale force conditions with a gale warning is now in effect. Winds will lighten Tuesday afternoon as high pressure to the west shifts over the waters. High pressure will be the dominant weather feature until the next weather disturbance arrives Thursday night which will increase winds and build seas again through Friday.

Rip Currents
Low risk today with low surf of about 1 foot. Increased risk will be possible on Tuesday due to increased northerly winds.
