Area Forecast Discussion National Weather Service Tallahassee FL 639 AM EST Thu Feb 20 2020

AVIATION. [Through 12Z Friday]

Widespread MVFR/IFR conditions have moved into the area. These conditions will continue through the TAF period with LIFR conditions possible at times today and tonight. Rain showers will overspread the region from west to east late this morning with a cold front expected to move through late in the TAF period.

PREV DISCUSSION [330 AM EST].

NEAR TERM [Through Tonight].

Northerly flow will prevail over much of the region through the day with increasing rain chances as an upper level disturbance moves over the region. At this surface, a warm front currently offshore will lift north through the day as a weak area of low pressure develops over the northern Gulf in response to the upper level disturbance. As this happens winds will becoming southeasterly over the Big Bend briefly later this morning before northerly flow returns behind the cold front in the afternoon. To the north and west of this surface low, and associated warm front, expect widespread showers to develop this morning through the early afternoon. These showers will then quickly progress south by the afternoon and evening as the surface low moves east of the region and the cold front pushes through the region. Much of the precipitation will be along and behind the cold front today with GA/AL counties seeing rain develop in the later morning hours and our Florida counties not seeing rain until the afternoon period.

SHORT TERM [Friday Through Saturday Night].

By Friday morning, deep layer subsidence will be overspreading the region as the upper-level shortwave moves off the Mid-Atlantic coast. The cold front will have cleared the southeast Big Bend and northwesterly flow will advect dry air into the region, scouring out any remaining cloud cover. Anomalously cool lower-tropospheric temperatures associated with the trough will prevent high temperatures from climbing out of the middle 50s region-wide, with low 50s more likely in GA and AL. Overnight, the calm center of the surface ridge will draw near and combine with clear skies resulting in temperatures dropping into the upper 20s to around 30 degrees. In addition to the freezing temperatures, frost will also be possible. Saturday and Saturday night will feature temperatures around 5 or so degrees warmer than Friday as ridging starts to build in aloft and dewpoints begin to creep up as easterly flow starts to take hold at the surface.

LONG TERM [Sunday Through Thursday].

Sunday will be sunny and mild as ridging dominates the Southeast. However, a more progressive pattern will result in a transition back to a wet regime by Monday. The good news is that we're not looking for an extended period of dreary weather, with another cold front drying things back out by Tuesday night or Wednesday through the end of the week.

MARINE.

Advisory conditions are expected to overspread the northeast Gulf in the wake of a cold front beginning tonight. Poor marine conditions will continue through Saturday, becoming more favorable through Sunday. An increase in winds and seas is expected again early next week ahead of another frontal system.

FIRE WEATHER.

Humid conditions along with increasing rain chances through the day will keep fire concerns low this afternoon. A cold front moves through later tonight and will bring increased winds and drier conditions for Friday.

HYDROLOGY.

Moderate to heavy rainfall is likely late this afternoon through the night with a frontal passage. The highest rainfall amounts (about 1 to 2 inches) are expected on the northern fringe or our forecast area. Another round of rain will be possible Monday into Tuesday. 7 day rainfall amounts show a little over 2 inches for parts of SE AL and SW GA with less than an inch farther south. This could push a few rivers into Minor flood stage by next week (especially along the Flint). The Apalachicola remains in minor flood and looks to remain there for the foreseeable future.

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.
