Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 325 PM EDT THU AUG 11 2016 .SHORT TERM (Today and Friday)... The surface low pressure system that brought heavy rainfall to the northeastern gulf coastal region continues to gradually shift westward along the northern gulf coast. In its wake, weak upper ridging is building into the Mid-Atlantic and southeast states as surface high pressure extends from the western Atlantic into the southeast U.S. For the rest of today, thunderstorms continue to develop along the Atlantic coast and interior portions of the Florida peninsula. As weak surface high pressure nudges into the region, south southeast low level flow will persist. This coupled with westward surging thunderstorm outflows, will allow storms to build westward through the remainder of the day into this evening. A few stronger storms may also develop, with gusty winds, frequent lightning, and heavy rainfall. Storms should push offshore this evening, with some lingering stratiform showers along the coast through around midnight. Thereafter, expect widespread mid and upper clouds will keep conditions overcast with light east/southeast winds. For Friday, conditions look to mostly mirror today. Morning marine thunderstorms will diminish as the seabreeze develops and subsidence overspreads the waters. Thunderstorms will once again develop first over the east Florida coast, then build westward from late afternoon through evening, eventually reaching the Florida gulf coast and moving offshore. Temperatures look to remain seasonable with highs in the low to mid 90s, and lows in the mid 70s inland, with upper 70s to near 80 degrees along the coast. Long Term (Friday Night-Thursday)... The models are in agreement with the upper high along the Carolina coast and the upper low that has been impacting the area over Louisiana. The low remains nearly stationary through Saturday as the high drifts over the Atlantic while building westward across the SE US. On the surface the ridge is weaker and influenced by the surface low over Louisiana but builds more firmly over the southeast by Saturday providing a south to southeast wind flow across the forecast area. Precipitation will be primarily along the east and west coast sea breeze merger along the west coast during the late afternoon. By Sunday the low has weakened and pulled into an approaching frontal band and upper trough over TX and the ridge is firmly in place across the SE. The surface ridge into the SE firmly reflects this also and the rain chances are slightly higher but still in the scattered category. The upper trough slowly progresses to the east as the ridge slowly weakens into Wednesday but the surface ridge continues into the SE. During this time frame the scattered afternoon convective storms will continue. By Wednesday an inverted upper trough forms over the Bahamas and moves near Florida Thursday as the model solutions diverge. && .AVIATION (18z TAFs)... Scattered storms continue to slowly drift westward across central and western Florida. These will continue to build westward, affecting most terminals through 00z Fri. Expect gusty winds, lightning, and torrential rainfall with storms, reducing visibilities to IFR levels at least temporarily. Storms should gradually move offshore by 02z to 03z Fri, with returning VFR conditions. Patchy fog/low stratus may develop overnight where any heavier rainfall occurs this afternoon, but widespread impacts are not expected. West to southwest winds near the coast this afternoon will become easterly overnight. && .MARINE... Surface high pressure will continue to build in to the north of the waters, resulting in persistent east to southeast winds. Winds and seas will come down each afternoon as the seabreeze develops, but will likely increase each evening and overnight as weak easterly surges develop. These surges may be accompanied by marine thunderstorms as they shift off the west Florida coast. Any marine storms may locally enhance winds and seas. Otherwise, winds of 10 to 15 knots and seas of 2 to 3 feet or less can be expected. && .FIRE WEATHER... A seasonably warm and humid airmass will remain in place with light southeast winds. Rain chances each afternoon coupled with continued moist southerly flow will keep humidities well below critical levels through the first half of next week. && .Preliminary Point Temps/PoPs...
