Scattered showers over the coastal areas of the Panhandle observed tonight, leading to raising the Probability of Precipitation over the coastal areas for the rest of the night. No other changes were made to the current forecast.

.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.
