000 FXUS62 KTBW 171311 AFDTBW Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 911 AM EDT Fri Aug 17 2018 .UPDATE... Latest RAP model has Atlantic high pressure ridging west with an axis across far north-central FL this morning. This will provide prevailing southeasterly low level flow...more southerly in the north...but light enough to allow onshore flow to form near the coast in afternoon sea breezes. The 12Z TBW sounding came in with a PWAT value of 1.58 inches...slightly below normal. Other sounding around the state had over 2 inches in the north with 1.5-1.7 inches central and south. Anticipate today being similar to yesterday with isolated to scattered showers and storms forming in the early afternoon then then increasing late afternoon and early evening in a convergence zone as the west coast breeze boundary pushes inland...along the I-75 corridor. Forecasts are on track but may make minor adjustments as afternoon convection get underway. && .AVIATION... 17/12Z TAFs. VFR prevail although SCT-NMRS TSRA form AFT 19Z-20Z with PSBL MVFR/LCL IFR. Light winds become SE and increase some during the morning and CONT for the afternoon...except shifting to onshore at TPA/PIE/SRQ. && .MARINE... High pressure ridge axis just north of the waters today provides southeasterly and southerly winds at gentle speeds.
