258 FXUS62 KTBW 181204 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 804 AM EDT Tue Jun 18 2024 ...New UPDATE, AVIATION... .UPDATE...
-- Changed Discussion --
Dry air aloft continues to deepen as seen in the 12Z TBW sounding and local ACARs data to keep rain chances very low today. Tight 6-7mb surface pressure gradient over the FL Peninsula and daytime mixing of strong winds aloft to produce gusty E winds again today preventing Gulf seabreeze. Lack of afternoon convection and cloud cover for warm temps well above normal values as well. These winds will also create dangerous marine and boating conditions. Latest grids and forecast on track.

&& .DISCUSSION... Issued at 416 AM EDT Tue Jun 18 2024 Ridging will continue to dominate our weather pattern over the next couple of days. As the pressure gradient is squeezed over us between the strong ridge and the deepening low pressure in the western Gulf of Mexico, breezy easterly winds are expected the next few days. With this strong ridging overhead, slightly warmer than average temperatures are expected (lower 90s) over the next couple of days and the strong easterly flow will focus the warmest temperatures along the west coast of Florida. Mostly rain free conditions are expected today as PWs will remain under 1.5 inch and only isolated thunderstorm chances are expected on Wednesday. Moisture will begin returning to the area later this week as a system in the Atlantic approaches the east coast. There still remains some uncertainty regarding the degree of intensity with this system, but one thing they do agree on is the increase in rain chances it brings to the Florida Peninsula as moisture streams across the state towards the latter half of the week and into the weekend. Temperatures during this time frame will continue to run above average, with the warmest temperatures being felt across the Nature Coast. Lower 90s will be seen across SWFL through Central Florida, with middle 90s expected across our northern counties. The warm temperatures along with the increase in moisture will lead to heat index values in the triple digits for most of the forecast area during the afternoon hours. && .MARINE... Issued at 416 AM EDT Tue Jun 18 2024 Strong easterly winds are expected the next few days along with elevated seas. A Small Craft Advisory remains in effect through today and into Wednesday morning. Additional advisories may be needed before winds finally diminish Thursday night. && .FIRE WEATHER... Issued at 416 AM EDT Tue Jun 18 2024 Breezy easterly winds are expected the next few days with high dispersion expected, but RH values will remain well above critical thresholds. Winds will diminish by the end of the week along with increasing rain chances. && .PRELIMINARY POINT TEMPS/POPS...
