307am EDT Fri July 3 2020

The long stretch of dry conditions across portions of the region looks to be coming to an end. A trough of low pressure surface and aloft will sink slowly south across north Florida today and tonight...and will persist over the region through the weekend. Surface ridge axis will remain well south of the area with southwest to west boundary layer flow off the warm Gulf waters. A series of U/L disturbances will ride over the boundary across the northeast Gulf and north central Florida over the next several days. Although exact timing is in doubt, expect shower/thunderstorm activity to increase over the northern Gulf waters, especially during the overnight hours, advecting onshore each day. Although the Nature coast is favored for the highest pops, it remains possible that the boundary will sink a bit further south at some point toward the Tampa Bay area. The west/southwest flow will also favor scattered to numerous showers and thunderstorms to develop over the interior during each afternoon.

High pressure surface and aloft will build back over west central and southwest Florida early next week with increasing large scale subsidence which will reduce probability of precipitation and increase daytime temperatures, especially over the interior. Another trough of low pressure will drop down over the northern/central peninsula late next week with an increasing chance of showers and thunderstorms.

Marine
Increasing chance of showers and thunderstorms through the weekend, mainly over the northern and central waters, which may create locally gusty winds and rough seas. Otherwise, winds and seas are expected to remain below advisory levels.

Fire Weather
No fire weather hazards are expected for the next several days as relative humidity values are expected to remain above critical levels.
