Area Forecast Discussion National Weather Service Tallahassee FL 651pm EST Wednesday Feb 19 2020 .NEAR TERM [Rest of Today and Tonight]... A weak cold front moved through the region this morning, leaving light northerly flow in place across the area. With this front south of the Florida Panhandle, skies have actually cleared across Srn Georgia and into the Florida Big Bend. In these areas, temperatures have warmed into the mid to upper 70s. The next shortwave, and eventual frontal system are approaching from the west. Cloudiness in advance of this feature is overspreading our western counties and should cover the remaining portion of the forecast area tonight. The best forcing for ascent, however, will remain back west of the region until the daytime hours on Thursday. Thus, while there is some lower end rain chances in the forecast this evening, Probability of Precipitation won't really begin ramping up until closer to 12z on Thursday. Long Term - Thursday Through Friday Night The slow-moving frontal boundary currently draped over the southeast will finally be pushed through and out of our area in the short term. A shortwave moving east from the Central Plains and a second shortwave moving south from the Great Lakes will interact, amplifying and deepening the trough, consequently pushing out the frontal boundary. As the front moves through the CWA, widespread and potentially heavy rainfall is expected early Thursday through Thursday night with cool and dry conditions arriving Friday. The front is expected to progress through our area nearly north-south, tightening the temperature gradient with Cold Air Advection and cloud cover to the north and daytime warming in the south. As such, highs Thursday will range from the mid-50s to the low-70s, and overnight lows dropping into the upper-30s to low-40s. Temps Friday will only get up to the mid-50s, dropping into the 30s, with temps hovering at or below freezing generally north of I-10. Long Term - Saturday Through Wednesday Highs Saturday will remain in the 50s and lows 30s until a trough swings through beginning Monday night. This trough will bring increased Probability of Precipitation into the region. As of right now, due to lower instability, thunderstorms are not forecast. The chance of rain will not be pushed out throughout the entire forecast period. While it may not rain all day, everyday, everywhere within our region, the chance of rain will persist due to the front stalling near the region. Highs Sunday through Wednesday will range from the upper 60s to lower 70s, while the lows will range from 40s to 50s. Cooler air will begin to move back into the region Wednesday. Marine Winds will be increasing and shifting southerly through Thursday with a Small Craft Advisory likely needed by Thursday night through Friday night for both winds and seas. Conditions should diminish below advisory levels by Saturday and remain less than 15 knots with seas less than 3 feet thereafter. There will also be widespread showers Thursday through Thursday night with a frontal passage and more rain expected for next week. Fire Weather Despite low and high afternoon dispersion values the next few days, there are no other fire weather concerns. Patchy fog is possible tonight. Hydrology Moderate to heavy rainfall is likely Thursday night with a frontal passage with the highest rainfall amounts on the northern fringe or our forecast area. Highest amounts would be around 1 to 2 inches. Another round will be possible Monday into Tuesday. 7 day rainfall amounts show a little over 2 inches for parts of SE AL and SW GA with less than an inch farther south. This could push a few rivers into Minor flood stage. Apalachicola at Blountstown is still in minor flood and looks to remain there for the next few days.
