Area forecast discussion, Jun 16, 2:39 PM EDT, 1 hour 24 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 239 PM EDT Sat Jun 16 2018 .NEAR TERM [Through Tonight]... Showers and storms generated along the seabreeze, and further inland associated with weak upper-level forcing will gradually diminish after sunset. Scattered areas of light rain could linger as late as midnight. Overnight lows will fall into the lower 70s under cloudy skies. .SHORT TERM [Sunday Through Monday Night]... The recent stretch of active weather may finally be drawing to a close as weak ridging starts to build over the region during the short term period. While some west-southwesterly flow will continue into Sunday afternoon resulting in scattered showers and storms, the 1000-700 mb flow becomes light and variable on Monday, which combined with the building ridging should return rain chances to the normal range (30-40 percent PoPs). Temperatures throughout the short term period will feature highs in the lower 90s and lows in the lower 70s. .LONG TERM [Tuesday Through Saturday]... Through much of the long term period, model guidance is in good agreement that at least some weak mid level ridging should remain in place across the Southeast. In fact, by Wed/Thurs, model guidance is showing that some drier mid level air will begin to work in from the east, which could further reduce afternoon shower and thunderstorm potential. As a result rain chances are generally at or slightly below normal for late June, in the 30-40 percent range. Given lower storm chances, afternoon temperatures will be a little warmer with a few spots getting into the mid 90s. Max daytime heat indices by mid week will be in the low 100s. && .AVIATION [Through 18Z Sunday]... VFR conditions will prevail through the TAF for just about all terminals (outside of thunderstorms). Showers and thunderstorms will bring with them the potential for IFR vis restrictions and gusty winds. The main exception to VFR will be near dawn at DHN where low-end MVFR to high end IFR visibilities and ceilings are expected. && .MARINE... Light winds and low seas are expected through the next few days. Some enhancement in winds and seas is expected near the coast with the daily sea breeze circulation. && .FIRE WEATHER... Low dispersions below 20 are possible Sunday afternoon. Otherwise, there are no other fire weather concerns. && .HYDROLOGY... A typical summertime pattern is expected, which will keep any widespread rainfall amounts low. However, as the steering flow becomes weaker by the first of the week, isolated heavy rainfall is possible from stronger thunderstorms. && .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
