Area Forecast Discussion National Weather Service Tallahassee FL 651 PM EST Fri Dec 4 2020

AVIATION. [Through 00Z Sunday]

Showers will continue to impact VLD over the next few hours reducing visibilities at times to MVFR/IFR levels. Otherwise a period of IFR ceilings is expected in the wake of the front and will clear from west to east through the night will all sites VFR during the early morning hours.

PREV DISCUSSION [119 PM EST].

NEAR TERM [Through Saturday].

A cut-off low is moving through the Southeast this evening. At the surface, a cold front is currently (1 PM EST) moving through Central Alabama and the western Florida Panhandle. A line of showers with a few embedded thunderstorms will continue to move through the region this afternoon and evening. Lightning has been very limited so far this morning but the showers in the FL Panhandle have shown weak rotation sporadically. With very high deep layer shear today, one or two weak, brief tornadoes cannot be ruled out this afternoon or evening. Higher dew points are slowly creeping farther northward this afternoon. Instability will remain low but a few storms may become strong enough to produce damaging straight-line winds this afternoon.

This evening, showers and thunderstorms will move out of the region as high pressure air moves in behind the cold front. Clouds will clear out tonight and lows will be colder in the upper 30s and 40s. Tomorrow will be mostly sunny with northerly winds. Highs will be in the upper 50s and lower 60s.

SHORT TERM [Saturday Night Through Sunday Night].

Another upper level cut-off trough is expected to propagate eastward along the northern Gulf coast starting Sunday, which will aid in the development of a Gulf surface low pressure system across the southern Gulf of Mexico. The apex of the upper level trough is expected to push through our region Monday morning, and merge with the northern jet stream upper level trough over north Georgia. As the upper level cut-off trough pushes through the region, enough forcing for ascent and divergence aloft will aid in the development of showers across our region. Much of the heaviest rainfall will likely be in the Florida Peninsula as the surface low tracks through the Orlando area into the Atlantic.

LONG TERM [Monday Through Friday].

As much of the rain falls across the region from the aforementioned system on Monday, cooler weather will once again establish itself across the region. The previously discussed northern jet stream upper level trough is expected to pivot across coastal Georgia and South Carolina. These lower heights will allow for cooler temperatures to develop across the region. Beyond the trough exiting off the eastern seaboard, surface high pressure and, and upper level ridging are expected to build over the region starting in the middle of next week. This will allow for a brief warming trend to develop starting Thursday of next week. Overall high temperatures will remain in the upper 50s to low 60s through Wednesday, and then climb into the upper 60s by Thursday. Lows through the early half of the week will remain in the mid to upper 30s starting Monday night, and slowly start to warm into the mid 40s by Friday night.

MARINE.

Winds will remain southerly at cautionary levels around 15-20 knots throughout the remainder of the day ahead of the cold front; however, the front is expected to push through our area for the remainder of the day. Behind the front, northwest/northerly flow is expected to take over, and remain near cautionary levels around 15-20 knots. Winds will drop below cautionary levels Saturday evening; however, will remain out of the north/northeast.

FIRE WEATHER.

Red flag conditions are not expected for the next several days.

HYDROLOGY.

Showers and thunderstorms will move through the region today; however, widespread rainfall totals will be less than an inch across much of the area. Portions of the Florida Panhandle may see locally heavier amounts of up to two inches. Based on the low rainfall totals expected, there are currently no flooding concerns at this time.

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.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
