Area forecast discussion, Feb 9, 5:25 AM CST, 21 minutes before
Area Forecast Discussion National Weather Service Tallahassee FL 625 AM EST Tue Feb 9 2021 .AVIATION... [Through 12Z Wednesday] Mostly IFR conditions and rain showers are expected today with a few thunderstorms mixed in. Rain chances should diminish into the late afternoon and evening, although mist will remain possible through the whole taf period. Ceilings are expected to become IFR to even LIFR/VLIFR overnight tonight with dense fog possible in some areas. && .PREV DISCUSSION [229 AM EST]... .NEAR TERM [Through Tonight]... A shortwave rotating across the northern Gulf early this morning will continue to spur the development of showers and thunderstorms from west to east across the area through much of the day. With the warm front to our south still, a stable layer at the surface will keep any thunderstorm development elevated with the main threats being small hail, heavy rainfall, and lightning. Light showers and mist may stick around into the evening hours, but thunderstorm chances should begin to diminish late afternoon as the shortwave exits the area. A low stratus deck is forecast to move overhead this morning and remain in place through at least tonight, with intermittent mist possible throughout the near term period. Fog development is expected overnight tonight and could become dense in some areas. .SHORT TERM [Wednesday Through Thursday]... In the upper levels, a weak ridge will be over the region. At the surface, a weak frontal boundary will lift northward through the region on Wednesday. On Thursday, a low pressure system will develop near Mississippi. On Wednesday, showers and thunderstorms will be more likely north of I-10 with POPs of 40 to 60 percent. On Thursday, showers and thunderstorms will move into the westernmost part of the region in the late afternoon or evening. Potential for severe storms will be low Wednesday and Thursday due to the absence of upper level support. Skies will be cloudy. Highs will be in the 70s. Lows will be in the upper 50s. .LONG TERM [Thursday Night Through Tuesday]... In the upper levels, a shortwave will move through the region Friday night. Otherwise, nearly zonal flow or weak ridging will be in place. At the surface, a slow moving low pressure system will linger over the region from Thursday night through Saturday morning. The best chance for showers and thunderstorms appears to be Thursday night through Friday night but uncertainty is high this far out. Temperatures will be cooler after frontal passage with highs in the 50s and 60s this weekend. .MARINE... Light southerly winds will increase slightly on Thursday ahead of the next low pressure system. Winds will be moderate and northeasterly this weekend. Showers and thunderstorms are expected with a weak system today and tomorrow, then a slow moving system is expected late this week. .FIRE WEATHER... Very light transport winds and low mixing heights will keep dispersion fairly stagnant for the next couple of days. Showers and thunderstorms will be possible today, with fog possible both this morning and again overnight tonight. .HYDROLOGY... Most local rivers are currently below action stage and none are in flood stage or forecast to reach flood stage at this time. This week will be fairly wet with a weak system expected today and tomorrow, then a slow moving system is expected late this week into the weekend. Forecast rainfall totals for the next five days are 1.5 to 2.5 inches. Flooding is not expected at this time but uncertainty is high regarding the system late this week. .SPOTTER INFORMATION STATEMENT... Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur (while following all local, state, and CDC guidelines) by calling the office or tweeting us @NWSTallahassee. && .PRELIMINARY POINT TEMPS/POPS...
