Area Forecast Discussion National Weather Service Tallahassee FL 319 AM EST Tue Jan 21 2020

NEAR TERM [THROUGH TONIGHT].

A shortwave passing overhead today will continue amplifying the eastern CONUS longwave trough and result in a lowering of heights. At the surface, high pressure will result in northeasterly winds transporting an airmass sourced from the Eastern Seaboard. The combination of these will result in afternoon highs a few degrees lower than yesterday. Expect about all locations throughout the Tri- State region to remain below 50 degrees today.

Lighter winds are expected overnight, which will allow temperatures to fall a couple degrees cooler than this morning. Thus, expect low to mid 20s on Wednesday morning with more widespread frost possible as well. Due to the fact that winds will be below 5 mph on average, we'll likely avoid Wind Chill Advisory criteria, but by virtue of very low temperatures to begin with, even very light winds could result in apparent temperatures below 20 in some spots.

SHORT TERM [WEDNESDAY THROUGH THURSDAY].

Large-scale subsidence and dry air will begin do decrease across the area as the center of the deep layer high pressure system slowly propagates eastward across the mid-atlantic states. Winds will become northeasterly and then easterly on Wednesday which will allow moisture and slightly warmer air into the area.

As a result, a warming trend that will start on Wednesday. High temps will reach the mid 50s and low 60s on Wednesday and Thursday respectively. The lows on Thursday morning will stay above freezing.

LONG TERM [THURSDAY NIGHT THROUGH TUESDAY].

A surface low will form and propagate eastward across the Ohio Valley through the weekend. An associated cold front will push through the area bringing increased precipitation chances starting overnight Thursday. A few isolated storms could be possible with this system, however, severe threat should remain low given the lack of instability.

The cold front, and the associated convective activity, will quickly exit the area overnight Friday. Cool and dry conditions are expected to return by Saturday morning. Temps could get quite cold again with lows forecasted to reach the mid 30s on Sunday morning. Dry conditions expected to persist through the end of the rest of the forecast period.

AVIATION. [Through 06Z Wednesday]

VFR conditions will prevail through the TAF.

MARINE.

Moderate to borderline small craft advisory criteria will continue through the day today before northerly flow increases again overnight. The small craft advisory has been extended to 12Z Wednesday and now includes offshore portions south of Apalachicola Bay.

FIRE WEATHER.

While Red Flag conditions are not forecast over the next few days, dry and cool conditions will prevail with high dispersion indices likely today.

HYDROLOGY.

A cold front will begin to move into the area on Thursday bringing another round of precipitation. The system will be very progressive, thus, not allowing heavy rainfall accumulations. Currently WPC is estimating widespread 1 inch or less, with the highest rainfall potential across the FL Panhandle. Given the slightly dry soil conditions in place across the area, flooding will not be a concern with this system.

SPOTTER INFORMATION STATEMENT.

Spotter activation is not requested. However, spotters are always encouraged to safely report significant weather conditions when they occur 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.
