Near Term - Through Today
Gradient between high pressure to the north and deepening low off of the Florida East Coast kept winds up enough to keep temperatures a few degrees above forecast lows this morning. Even so, most areas dropped below freezing, with a few locations in the Panhandle and SE Alabama reaching the mid 20s. Moderation will begin today, as a shortwave ridge moves over the region. Expect highs to range from the lower 50s to upper 50s under a veil of thin cirrus. Updated temperatures just a bit to account for slightly slower than forecast warming this morning. Otherwise, the forecast is on track.

.SHORT TERM [Wednesday Night Through Friday]... Dry conditions continue through early Thurs before coming to an end as an amplifying upper-level trough digs southeast from the Plains. This feature will aid in the development of a low-pressure system at the surface that is forecast to race up the OH/TN valley and drag a cold front to its south. The front is expected to arrive at our area Thurs night and bring a line of showers and possibly some thunderstorms. Rain subsequently returns to the forecast with a slight chance of thunder in the short-term period. The highest Probability of Precipitation are in the western FL Panhandle & marine zones, and AL counties late Thurs. Elevated Probability of Precipitation then shift eastward with the front's progression Fri morning and into the afternoon.

Slight and temporary warming is expected before the cold front passes with high temperatures mostly in the 60s on Thurs and climbing to around 70 on Fri. Lately, the NBM has shown a cold bias for min T just before frontal passage, so decided to blend in some Euro guidance to show slightly warmer pre-frontal temperatures with lows in the low 40s.

.LONG TERM [Friday Night Through Wednesday]... The aforementioned cold front should exit our area Fri evening and leave behind a cooler and drier airmass in its wake. Therefore, mostly clear skies are expected on Sat as surface high pressure builds over our area. By Sun, some tropical moisture gets advected from the TX coast to the northern Gulf coast but appears to remain mostly offshore, so kept low-end Probability of Precipitation in the forecast, but any rain that occurs will likely be confined to the coastal and marine zones through early Mon. The remainder of the long-term period is expected to be cool and dry with highs in the 60s and lows in the 40s.
