545 FXUS62 KTAE 150821 AFDTAE AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 321 AM EST Mon Dec 15 2014 .Near Term [Through Today]...
-- Changed Discussion --
With a weak Sfc high pressure ridge anchored in from the Carolinas SW into our CWA, very little change to our current fcst is expected today. After yet another mostly clear and chilly start over the region this morning, afternoon temperatures will rebound quite well, with the possibility of a repeat of Sunday`s 35-40 degree diurnal ranges. High temps are expected to climb into the mid to upper 60s across much of SW and SC GA, to the upper 60s to the lower 70s elsewhere. Skies are not expected to be entirely clear however, as a band of Cirrus (associated with an upper level low over OK and KS) moves steadily eastward through the CWA, with its only impact temporarily dimming the bright sunshine. .Short Term [Tonight Through Wednesday]... The ridging that has been the dominate feature for the last several days will slide eastward as an upper level trough lifts north of the area on Tuesday. With low level moisture returning ahead of the weak cold front tonight, some areas of fog could develop. The front will push through the area during the day on Tuesday with just some scattered showers associated with it. Afternoon high temperatures on Tuesday will be rather warm ahead of the front with low to mid 70s expected over most of the area. A slight cool down back to near average temperatures for this time of year is expected on Wednesday behind the front. .Long Term [Wednesday Night Through Monday]... The next system of interest is expected to arrive between the Friday night and Saturday time frame. There remains some model disagreement with this system with the ECMWF showing a much stronger system than the GFS. The Canadian model is not as strong as the ECMWF, but it shows more moisture and better chance of rain over the area than the GFS does. The WPC is leaning towards a better chance of rain as well, so with this in mind, PoPs were trended upward. A slight chance of thunderstorms was also added across the western third of the area out of respect for the stronger ECMWF scenario. Temperatures are expected to be mostly near seasonal averages through the period.

Light winds and low seas will prevail through today. For tonight through Tuesday, an uptick of winds to near 15 knots will be possible behind a cold front, mainly to the west of Apalachicola. Winds and seas will then subside once again for Wednesday and Thursday with another increase expected for Friday into next weekend.

-- Changed Discussion --
Despite generally fair, seasonable, and dry weather today, conditions will not be dry enough to cause any Red Flag concerns. Increasing moisture and a chance of rain tomorrow will also preclude any fire weather hazards.
