Area Forecast Discussion National Weather Service Tampa Bay Ruskin FL 320 PM EDT Thu Aug 12 2021 .DISCUSSION... We have another day or so of rather typical summer-time conditions before TC Fred enters the picture. Current NHC forecast has Fred regaining tropical storm status between Cuba and the Florida Straits by Friday evening, then moving northwest through the eastern Gulf just offshore the west coast of Florida Saturday and Sunday before making landfall in the panhandle of Florida Sunday night. While Fred is forecast to continue strengthening while moving through the eastern Gulf, it is not expected to become a hurricane before landfall due to unfavorable shear. For the rest of today, scattered to numerous showers and storms will develop this afternoon and move slowly westward toward the coast through the evening hours. We will have to watch for the possibility of some stronger storms again as the east and west coast sea breeze interact west of I-75. Friday will be another typical summer day with scattered to numerous afternoon and evening storms moving from east to west. Fred should be moving through the Florida Keys early Saturday, then continue northwestward through the eastern Gulf Saturday and Sunday. This is where the forecast gets tricky. 12Z guidance continues to struggle with the track and intensity of Fred. Our forecast will be based on the official NHC forecast track, so widespread showers and some storms will overspread the area from southeast to northwest on Saturday and continue through most if not all of Sunday. While it won't be raining all the time, we do expect frequent showers, and could see locally heavy rainfall where persistent bands set up. The highest totals with Fred should be along the coast based on the forecast path, but even inland areas should see their fair share. Current thoughts are 3 to 5 inches with locally up to 8 inches. Fred should be moving out of the picture on Monday with some residual impacts expected. Deep tropical moisture will remain overhead resulting in numerous showers and storms. We should finally return to more typical summer-time conditions for Tuesday through Thursday as the surface ridge axis builds back over the state resulting in scattered to numerous mainly afternoon and evening showers each day. && .AVIATION... Brief MVFR/IFR conditions will be possible at the terminals between 19-24Z as SHRA/TSRA develop over the region and have depicted short Tempo groups during this time frame to cover this. Outside of the convection VFR is expected. East winds in the 7 to 10 knot range will prevail except becoming onshore from KSRQ north to KTPA and KPIE terminals between 18-19Z with the sea breeze with higher gusts in the vicinity of TSRA. East-northeast winds in the 5 to 7 knot range can be expected after 02Z tonight through early Friday morning. && .MARINE... Main hazards through Friday will be for scattered to locally numerous showers and storms moving off the coast each evening. These storms could have strong gusty winds and even some small hail. Tropical depression Fred located just north of eastern Cuba is forecast to move west-northwest and then northwest, reaching the Florida straits as a tropical storm by Friday night and continuing northwest through our offshore waters over the weekend. Expect rapidly deteriorating conditions from south to north late Saturday and Saturday night with Tropical Storm conditions possible until late Sunday night or early Monday. Mariners are urged to check the latest forecasts before heading out this weekend. && .FIRE WEATHER... No fire weather concerns. Widespread heavy rains likely as Fred moves northwestward just off the Florida Gulf coast this weekend. && .Preliminary Point Temps/PoPs...
