Area forecast discussion, Jul 26, 7:15 PM EDT, 24 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 715 PM EDT Wed Jul 26 2017 .AVIATION [Through 00Z Friday]... Scattered showers and storms will continue to drop southwest into the region this evening. These storms would primarily impact VLD and ECP, but possibly TLH as well. Overnight, expect LIFR restrictions at TLH, ABY, and VLD, with less confidence at ECP and DHN. Expect storms to be concentrated in the late afternoon once again tomorrow. && .PREV DISCUSSION [301 PM EDT]... .NEAR TERM [Through Tonight]... An upper level shortwave near the Georgia coast will persist through the near term. An MCV rotating over southeast Georgia this afternoon will help to generate scattered to numerous showers and thunderstorms particularly in a stretch from TLH to VLD (higher chances near VLD). Convection will be on a diminishing trend after 00z with the better chances (30-40%) remaining across the eastern portion of the CWA. For the second half of tonight, PoPs will decrease to about 20 percent with the focus still across the eastern portion of the CWA, but with the addition of the coastal areas. Lows overnight will only drop into the mid 70s inland to upper 70s along the coast. .SHORT TERM [Thursday Through Friday Night]... The weak upper low over the southeast will continue to influence rain chances for Thursday. PoPs will be in the 30-50% range with the highest in south Georgia and the Big Bend. By Friday upper level flow becomes more zonal ahead of the approaching trough. Friday PoPs will be slightly lower 20-40%. Highs will be in the lower 90s with warmer temps to the west where rain chances are lower. .LONG TERM [Saturday Through Wednesday]... The trough over the eastern US will shift east through the period. It will bring a weak front that will increase shower and thunderstorm chances for the weekend. Drier air will arrive by late Sunday before rain chances increase again mid week. PoPs will generally be 30-60% with the highest chances in the Big Bend. Highs will be in the upper 80s with lows in the low 70s. .MARINE... Winds will be westerly 5 to 10 knots through Thursday then will increase to 15 knots through the weekend. Seas will be 3 feet or less. .FIRE WEATHER... Hazardous fire weather conditions are not expected over the next several days. .HYDROLOGY... All area rivers are below flood stage. A few heavy showers and thunderstorms could lead to brief localized flooding. && .PRELIMINARY POINT TEMPS/POPS...
