GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 805 Pm Edt Wed Apr 17 2024
Synopsis - High pressure in the atlantic will remain in place through the end of the week, providing warm and dry conditions across the coastal waters and favorable marine conditions. Winds shift to the west-southwest by the weekend as a cold front ahead of a cold front that is expected to arrive by Monday and bring the next chance of rain across the area, but no headlines are expected at this time.

Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 803 PM EDT Wed Apr 17 2024

New UPDATE, AVIATION

UPDATE
Stacked ridging over the region continues to produce subsidence aloft trapping the dry airmass in place over the area. The surface pressure gradient is relaxing as high pressure weakens across the FL Peninsula. Expect more above normal temperatures while humidity remains fairly low then a more pronounced and cooling west coast seabreeze should push further inland Thursday.
Latest grids and forecast in good shape.

AVIATION
(00Z TAFS)
VRF conditions continue with mostly clear skies and light/variable winds tonight then bay/seabreeze winds Thursday afternoon.

DISCUSSION
Issued at 223 PM EDT Wed Apr 17 2024

The dry and stable weather pattern continues as mid level ridging in the Gulf of Mexico and surface high pressure in the Atlantic continues to remain in place. By late week, there will be some flattening of the ridge as a large upper level low drifts across northern Ontario and our flow aloft will transition from northwesterly to more of a westerly (zonal) orientation for the upcoming weekend. Meanwhile, this upper level low in Canada and the associated low pressure system will drive a cold front across the Eastern Seaboard by the weekend and as this occurs, the Atlantic high pressure will shift further offshore with the surface ridge axis setting up to the south of the area. With a gradual uptick in deeper moisture and a mostly WSW flow in place for the weekend, there may be a few light showers that develop in our interior areas as the sea breeze collision occurs over the eastern side of the peninsula. This also seems to be supported by recent guidance showing some potential for light pockets of QPF over the weekend associated with some of this sea breeze activity but for now will hold off on adding any PoPs to the official forecast as confidence still remains low.

By late weekend, a southern stream shortwave trough will swing across the lower Mississippi Valley and this will support the development of a surface low around the northern Gulf Coast. This surface low will quickly shift off to the northeast as it moves offshore of the Carolinas and rain chances will increase area-wide as the aforementioned cold front slides southward across the peninsula on Monday. Models then show the frontal boundary sliding south of the area by Monday night with drier air then building into the area as high pressure builds in from the north. While there will also be some slightly cooler air in the wake of the frontal boundary, particularly for the northern half of the area, temperatures are generally expected to remain normal through the end of the extended forecast period as any cold air advection behind the front looks limited at this time.

MARINE
Issued at 223 PM EDT Wed Apr 17 2024

High pressure in the Atlantic will remain in place through the end of the week, providing warm and dry conditions across the coastal waters and favorable marine conditions. Winds shift to the west-southwest by the weekend as a cold front ahead of a cold front that is expected to arrive by Monday and bring the next chance of rain across the area, but no headlines are expected at this time.

FIRE WEATHER
Issued at 223 PM EDT Wed Apr 17 2024

Minimum RH values will continue to drop below critical levels through the remainder of the week in inland areas as a dry air mass remains in place, though wind speeds will be light enough to preclude any red flag concerns. Humidity values will finally start to recover by the weekend as winds become southwesterly ahead of a cold front that is expected to arrive by next Monday, which will bring the next chance of rain across the region.
