Area Forecast Discussion National Weather Service Tallahassee FL 629 AM EST Fri Jan 17 2020

AVIATION. [Through 12Z Saturday]

Easterly wind speeds will increase to around 10 to 15 knots this afternoon. Wind gusts up to 20 - 25 knots is possible during the peak heating hours and across SW GA and eastern Florida Big Bend. Meanwhile, slightly lower wind speeds are expected for terminals further west. VFR conditions will prevail through the TAF period.

PREV DISCUSSION [330 AM EST].

NEAR TERM [Today].

Deep layer ridging will prevail today in the wake of the overnight frontal passage. Highs will climb into the upper 60s to low 70s across north Florida, and will remain in the lower 60s elsewhere as a wedge front sits across S GA/AL. While we won't be completely cloud free today, we will see more sun than recent days.

SHORT TERM [Tonight Through Sunday].

A shortwave moving through the Upper Mississippi Valley and Midwest on Saturday will drag a cold front into the Southeast. Return flow over the coastal front in advance of the cold front will result in increasing rain chances across the Panhandle and SE AL through the day on Saturday. The cold front will pass through the Tri-State region on Sunday as a southern stream wave merges in with the northern stream over the Southeast. Rain is expected region-wide overnight on Saturday through Sunday afternoon. Prior to the frontal passage late on Sunday, highs and lows will remain above average.

LONG TERM [Sunday Night Through Friday].

A blast of Arctic air is expected in the wake of the weekend cold front as another shortwave deepens the eastern CONUS trough early next week. While we most likely won't be breaking any records, low will fall into the mid 30s on Sunday night, then into the upper 20s both Monday and Tuesday night. Afternoon highs on Monday and Tuesday will also remain below average with low to mid 50s forecast region-wide. We'll gradually warm back to seasonal levels as ridging builds in mid to late week.

MARINE.

Advisory conditions will continue through tomorrow afternoon as high pressure noses into the northeast Gulf. A brief dip below headline conditions is forecast later in the weekend, before Advisory conditions are once again expected behind a cold front. Expect showers and isolated thunderstorms both Saturday and Sunday.

FIRE WEATHER.

Dry conditions are expected this afternoon with RH values in the low 30s across the region. Northeasterly transport winds will increase throughout the day to around 15 to 20 mph. This will lead to high dispersions for eastern Big Bend and portions of southwest Georgia (>75). Meanwhile, soil moisture content across SE Georgia and eastern Big Bend is low. These conditions make for a low-end fire weather concern, however, red flag criteria is not met.

On Saturday, moisture will increase ahead of the next cold front, thus, no hazardous fire weather is expected.

HYDROLOGY.

Rainfall amounts over the next seven days are expected to be an inch or less. Due to recent heavy rainfall in north and central Georgia, dam releases upstream are resulting in minor flooding along the Apalachicola River at Blountstown. Elsewhere, flooding is not expected.

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.
