AREA FORECAST DISCUSSION

.Near Term [Through Today]...
A shortwave trough will move through the region this morning.
Ahead of this feature, mid and high level cloudiness will
continue to stream over the region. By late morning and early
afternoon, as the main trough axis moves east of the region,
skies will become mostly sunny allowing for temperatures to warm
into the mid to upper 70s.
.Short Term [Tonight Through Sunday]...
Upper trough over the region tonight will slide eastward through
the weekend and be replaced by an upper ridge by Sunday. A very
dry and seasonable airmass will remain in place with slowly
modifying temperatures. Low temperature in the mid to upper 40s
tonight will warm to the upper 40s to lower 50s by Sunday morning.
Highs in the upper 70s on Saturday will rise to the lower 80s by
.Long Term [Sunday Night Through Friday]...
An upper level ridge, with it axis over the Mississippi Valley at
the start of the period, will drift east of the area by Monday.
At that point, we will see some amplification of the ridge as an
upstream trough digs into the central U.S. Eventually, this
trough will slide eastward. However, there are differences among
the models in the timing of this eastward advance. Surface high
pressure over the Central Gulf Coast on Sunday will move off the
Southeast U.S. coast early next work week. The position of the
deep layer ridging just to our east will keep PoPs at a minimum.
Slight chance PoPs do not return return to the forecast until
Wednesday and Thursday. A front will be approaching from the
northwest on Thursday. However, the 12Z run of the GFS is now
much less progressive than earlier runs to bring it through the
forecast area. The consensus of the current suite of model
guidance keeps any weak tropical lows confined to the Caribbean
Sea or Bay of Campeche during this period.
[Through 12Z Saturday] Aside from a CS layer between 20kft and
25kft moving through the region on Friday morning, skies will be
clear throughout the remainder of the TAF cycle with light N to
NE winds during the daytime hours.
High pressure west of the area and low pressure well to the south
will keep northeasterly flow in place over the waters through the
weekend. Winds may occasionally approach 15 knots during the
overnight hours but no headline conditions are expected. High
pressure will slide over the waters by late Sunday into Monday
with very light winds and minimal seas. As the high slides
eastward, onshore flow will develop by late Monday and Tuesday.
Dry conditions will continue through the next few days across the
region. Relative humidity values will approach critical levels in
North Florida on Friday and Saturday afternoons, but red flag
criteria are not expected to be met.
Due to the ongoing dry spell, there are no hydrologic concerns
across the region.
