Area Forecast Discussion National Weather Service Tallahassee FL 759 PM EST Wed Dec 11 2019

NEAR TERM [Through Tonight].

The cold front that moved through last night is well to our south with north-northeast winds in its wake. However, clouds and rain continue to move along lingering lift. Although there has been a slight increase in dew points this evening, the rain is going to be very light once it reaches the ground, if it does at all. Had a hard time with the POPs tonight give the chance we don't see any accumulation. But don't be surprised to see a few sprinkles overnight and into the early morning hours. Cooling tonight will be more exaggerated in southern Alabama/Georgia due to relatively less cloud coverage. Lows in the northern portion of the CWA will dip in to the low 40s with the southern areas remaining a little warmer only reaching the mid to upper 40s. Fog is not a concern for the area as it has been the last few nights.

PREV DISCUSSION [609 PM EST].

SHORT TERM [Thursday Through Friday Night]. Unsettled weather pattern will remain in place through Friday as the next set up shortwaves move through the base of the broad trough over the eastern CONUS. A strong 1040mb high over New England will keep northeast flow in place across the forecast area as weak low pressure develops over the Gulf ahead of the next shortwave. Expect isentropic lift to increase by Thursday evening with rain spreading across much of the area. There is still uncertainty as to how deep the low pressure gets and where exactly it tracks. However, it currently appears that the warm sector is unlikely to make it very far inland, limiting the risk for any strong to severe storms with this system. However, the rain alone will be beneficial with a widespread 1 to 2 inches possible.

With plenty of clouds and the northeasterly low-level flow, temperatures will remain below normal Thursday afternoon. Temperatures will be a few degrees warmer Friday afternoon as the wedge of high pressure breaks down.

LONG TERM [Saturday Through Wednesday]. Seasonal temperatures and drier conditions are expected over the weekend as the Friday system exits to the northeast. However, another round of rain is likely by early next week as another cold front approaches.

AVIATION. [Through 00Z Friday]

Very light rain showers continue across the area and will break briefly overnight before returning Thursday afternoon. Winds shift to the northeast and could remain elevated, 10-15 knots, through the TAF period. CIG heights are around 2500-3500 but may drop below that towards the very end of the TAF period.

MARINE. Strong northeasterly winds will continue through Thursday as strong high pressure remains in place along the eastern seaboard. Conditions should improve by Friday into Saturday as weak low pressure develops over the Gulf and the gradient weakens. A Small Craft Advisory will remain in place into Thursday. Increasing onshore flow will return by late in the weekend ahead of the next cold front.

FIRE WEATHER. No fire weather concerns.

HYDROLOGY. Light rain overnight into Thursday will generally be less than a tenth of an inch. Heavier rain is expected Thursday night through early Saturday, with amounts of 1 to 2 inches expected. This should not cause any issues on area rivers and streams.

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.
