Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 330 PM EDT Thu Jun 22 2017 .SHORT TERM (Tonight-Friday)... High pressure will continue to build into the area through Friday with some drier air moving in and suppressing rain chances, 30-40 percent for early tonight and 20-30 percent on Friday. Light winds will pick up from the SE later Friday morning and then the sea breeze will take over during the afternoon shifting winds to onshore near the coast. Lows tonight will be in the lower to mid 70s inland and mid to upper 70s coastal. Highs Friday will generally be in the lower 90s, with some upper 80s at the beaches. .MID TERM/LONG TERM (Friday night-Thursday)... A strong U/L ridge will hold over the Florida peninsula Friday night through Sunday. On Monday and Tuesday, a strong U/L disturbance will push across the Great Lakes and Ohio river valley with an associated U/L trough digging along the eastern seaboard and Florida peninsula. As the trough lifts northeast off the mid Atlantic coast Wednesday and Thursday, an U/L ridge will build back over the southeast U.S. and Florida. At the surface, the persistent area of high pressure over the western Atlantic with a ridge axis across the Florida peninsula will hold over the region Saturday...but will begin to slide east of the forecast area on Sunday. Atmosphere will remain conditionally unstable and daytime heating will allow scattered afternoon showers and thunderstorms to develop Saturday and Sunday with the best areal coverage over the interior where the collision of the east/west coast sea breeze boundaries is expected. Thunderstorm activity will gradually dissipate during the evening hours. Lower heights combined with an approaching frontal boundary will aid destabilization on Monday, Tuesday, and Wednesday afternoons with scattered to numerous showers and thunderstorms each day. Moisture pooled south of the boundary will also allow PCPW values to increase to AOA 2 inches which will create the risk for locally heavy rain. Transition day on Thursday as high pressure surface and aloft begins to build back over the forecast area with large scale subsidence gradually increasing...and pops lowering a bit. However, scattered afternoon thunderstorms are expected to develop with highest pops along the coastal counties south of Tampa Bay in region of best available deep layer moisture and L/L convergence along the west coast sea breeze boundary. Temperatures will run a few to several degrees above climatic normals over the weekend, then return back to near normal early next week due to the increasing cloud cover. && .AVIATION... VFR conditions prevailing across all terminals this afternoon with southeast winds between 8-10kt shifing to onshore at the coastal TAF sites. Scattered afternoon thunderstorms, with best convective development over the northern terminals, will be possible between 19z-02z which may temporarily bring MVFR/local IFR conditions. Winds subside tonight then increase to 8-10kt after daybreak tomorrow under the prevailing southeast flow. && .MARINE... High pressure will build across the coastal waters from the Atlantic through Saturday keeping generally SE winds in place with an afternoon sea breeze developing near the coast. For Sunday through Tuesday, the high pressure ridge will get pushed off to the south and east as a trough settles just north of the state and washes out, with high pressure to the north bridging across the remnant boundary by the end of the period. This will turn winds more to the E/NE for early next week with afternoon sea breezes dominating the flow. Scattered thunderstorms can be expected each day. No headlines are anticipated through the period. && .FIRE WEATHER... No concerns as relative humidities will remain above 35 percent and winds and ERC values below critical thresholds. && .Preliminary Point Temps/PoPs...
