149 FXUS62 KTAE 141601 AFDTAE AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 1101 AM EST Sun Dec 14 2014 .Near Term [Through Today]...
-- Changed Discussion --
Another sunny, dry day is in store with deep ridging centered over the Southeast. The 12Z Tallahassee sounding showed a very shallow layer of higher RH near the surface associated with a strong inversion. The atmosphere aloft was much drier, and the dewpoints should mix out late this morning or this afternoon, similar to yesterday. Only minor tweaks were made to the existing forecast.

.Short Term [Tonight Through Tuesday]... High pressure will be centered just north of the forecast area tonight. This will allow for another chilly night with lows Monday morning dropping into the low to mid 30s. By Monday, the pattern will be in transition as high pressure moves off the East Coast and a storm system moves across the Plains. Little in the way of return moisture or even deep layer forcing with this storm system will keep rain chances very low Monday night into Tuesday. High temperatures Monday and Tuesday will finally return to above normal values, and possibly exceed 70 degrees in a few areas. .Long Term [Tuesday Night Through Sunday]... In the wake of a mainly dry cold front on Tuesday afternoon, cooler and drier air will return to the region by the middle of the week. Model guidance continues to remain in good agreement that Wed-Thurs should be under the control of high pressure with slightly below normal temperatures each day. By Friday, the models begin to diverge with a more energetic 14/00z Euro indicating a higher amplitude trough moving across the Central and Southern Plains leading to strong surface cyclogenesis across the Western Gulf. The 14/00z GFS has a similar pattern - though weaker solution. While it`s too early to speculate about strong storms, both models seem to suggest that rain chances will be increasing late Friday and into Saturday. Thereafter, considerable uncertainty abounds. Maintained a forecast a little closer to climatology for the end of the period, though cooler conditions could be in the offering if the Euro were to verify. .Aviation... [Through 12Z Monday] VFR conditions are expected to prevail through the period with light winds. .Marine... Northwest winds will weaken later today as high pressure moves near the marine area. On Monday, winds will shift to the south ahead of an approaching cold front. On Tuesday, a cold front will pass through the northeast Gulf and will increase winds to moderate levels. High pressure will move in behind this front, resulting in light winds and low seas for the remainder of the work week. .Fire Weather... Fair weather will continue through Monday, with a gradual warming and moistening trend, especially during the afternoons. With a high pressure system remaining in place, surface and transport winds, as well as daytime mixing heights, will remain low. This combination will keep daytime dispersion values at unusually low levels. .Hydrology... With generally dry weather expected through the next several days, rivers will remain well below flood stage.
