705 FXUS62 KTAE 111451 AFDTAE AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 951 AM EST Thu Dec 11 2014 .Near Term [Through Today]...
-- Changed Discussion --
An upper level shortwave trough will move through the area today. There are currently high clouds over most of the CWA, particularly near the Gulf Coast. At the sfc, high pressure centered over the mid-Mississippi Valley is bringing northerly flow and cool dry air to the region. Cloud cover will decrease during the afternoon hours as the trough moves further away. High temperatures will continue to be on the cool side, generally in the mid to upper 50s.

.Short Term [Tonight Through Saturday]... With a trough in place along the eastern seaboard generating deep northerly flow across the forecast area, expect to see a continuation of the dry and seasonably cool weather through Saturday. Highs are expected to be in the upper 50s to lower 60s Friday and Saturday afternoons, with morning lows hovering around freezing. .Long Term [Saturday Night Through Thursday]... The amplified upper pattern will translate eastward during the latter half of the weekend, with an upper ridge moving from the Central Plains towards the Appalachians. However, with a weak pressure gradient in place and neglible return flow (along with the proximity of the winter solstice), the airmass will be very slow to modify, keeping temperatures a little below climo for both Sunday and Monday. An upper low will eject from the Desert Southwest by Monday morning and push towards western Tennessee by Monday night. Guidance is in better agreement this morning with deamplifying the upper low with time and carrying the bulk of the system well north of the forecast area. The trailing front will cross the forecast area on Tuesday, bringing some chance of rain. However, with the best dynamics remaining well north and the lack of deep moisture (from the aforementioned minimal return flow), a significant rainfall event is not likely with just scattered PoPs in the forecast. .Aviation... [Through 06Z Friday] VFR conditions will prevail through the period with light northwesterly flow. .Marine... Winds will generally remain out of the north into the weekend as high pressure holds in place northwest of the waters. Winds may occasionally reach 15 knots during the overnight hours the next few days. Winds will weaken late in the weekend as high pressure builds over the waters before turning onshore early next week. .Fire Weather... Relative humidity values will approach critical levels during the afternoon hours through Saturday. However, durations are unlikely to be met. Thus red flag conditions are unlikely for the next few days. .Hydrology... With all rivers below action stage and no rain expected for through the weekend, there are no flooding concerns.
