Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 220 PM EDT Thu Oct 21 2021

. Low Dispersions Expected On Friday .

DISCUSSION. High pressure over the Atlantic will maintain an east-southeast wind flow over the forecast area through Friday. A weakening cold front will sink south through the region on Saturday with high pressure then rebuilding in over the southeastern U.S. in the wake of the front with an easterly flow continuing. An increase in moisture will support increasing rain chances, mainly across the southern half of the forecast area Friday into Saturday, and then across most of the area during Sunday and Monday as the aforementioned front stalls out across the southern peninsula with the highest rain chances (Pops 50- 60%) focusing across south central and southwest Florida where the best available moisture, weak impulses moving through the flow aloft, and the stalled frontal boundary will reside.

Now during Tuesday and Wednesday an upper level trough and attendant surface low will be lifting northeastward up along the mid Atlantic coast. In the wake of these features high pressure with drier air building in from the west will support lower rain chances across the forecast area. During Thursday models show a strong upper level trough and attendant surface low moving from the lower Mississippi valley across the Southeastern States with a trailing cold front approaching from the west. This system will bring the next chance for showers and storms to the region as the front move into and through the region, and a few strong storms could be possible, so stay tuned. Temperatures will run above seasonal norms with overnight lows in the upper 60s to lower 70s, with daytime highs climbing into the upper 80s each afternoon.

AVIATION. 21/18Z-22/18Z. VFR prevails for the next 24 hours with FEW-SCT CU/SC at 3 to 6K FT under some CI. Winds E to SE shift during the afternoon . SW to NW at TPA/PIE/SRQ and NE elsewhere. Light and VRBL over night then E Fri morning.

MARINE. High pressure over the Atlantic will maintain an east to southeast wind flow over the Gulf waters through the end of the week and into the weekend with a weak pressure pattern supporting an onshore sea breeze component along the coast each afternoon. On Saturday a weak cold front will sink south through the waters. The front will then stall out across the southern waters during Sunday and Monday as high pressure rebuilds in north of the waters with an east to southeast flow continuing along with shower chances over the central and southern waters. Wind and seas will be higher in the vicinity of showers and thunderstorms, otherwise no headlines are expected.

FIRE WEATHER. Weak 20 foot winds and transport winds will support low dispersions over the region the remainder of the afternoon and again on Friday. An increase in moisture and rain chances is expected across the southern half of the forecast area on Friday, then across all of the area during the weekend and into early next week. Humidity values are forecast to remain above critical levels with no other fire weather hazards expected.
