.NEAR TERM [Through Today]...
Tracking the dry cold front though the CWA this morning with timing
roughly 04-06 ET across SE AL and western FL panhandle counties, 07-
09 ET across the SW GA and central FL panhandle counties, and 10-12
ET through the FL Big Bend and the rest of SW GA. Again, little
moisture to work with so no precipitation expected. Breezy northwest
winds will accompany the front with gusts up to 25 MPH. High
temperatures will be cooler with western extent through the CWA
given the earlier frontal passage. Readings will be in the mid-upper
70s west of the Flint/Apalachicola rivers and lower 80s east of this
.SHORT TERM [Tonight Through Sunday]...
With the cold front expected to be well to the east of the region
by tonight, much cooler and drier air will continue to pour into
the region. High pressure by Saturday morning will still be back
across the Southern Mississippi Valley, so a breezy cool advective
regime overnight should result in fairly uniform temperatures
across the region in the mid 40s. Overnight lows were last in the
40s in Tallahassee on May 7th.
Throughout the day on Saturday, surface high pressure will spread
eastward and eventually center over the Southeastern States by
Sunday morning. Even with full sunshine on Saturday, temperatures
will only warm into the mid 70s across the region with relative
humidities in the low 20 percent range in the afternoon.
With the high pressure area essentially in place across the region
by Sunday morning, a very favorable environment for strong
radiational cooling will be in place. Model guidance has been
trending slightly cooler with some of the gridded guidance showing
lows Sunday morning into the upper 30s. With the high centered
nearly overhead and a dry atmosphere, will trend the low
temperature forecast down a couple of degrees, which results in
lows across the inland areas in the 40-43 degree range.
With the high in place over the region on Sunday, expect a sunny
day with temperatures a little warmer than on Saturday. It`s
possible a few sites will reach 80 degrees Sunday afternoon.
.LONG TERM [Sunday Night Through Friday]...
After one additional night of chilly temperatures Sunday night,
the local airmass will begin to modify and warm through the
middle of the week. High pressure building off the Mid Atlantic
Coast on Tuesday night will start a period of moderate easterly
flow across the Eastern Gulf Coast States which will result in an
increase in cloud cover and temperatures essentially returning to
climo, with lows in the mid 50s and highs right around 80.
.AVIATION [Through 06Z Saturday]...
Surface cold front roughly lies from KCTJ-KMOB at 06Z and moving
eastward. Expect the front to enter southeast AL over the next few
hours, crossing KDHN around 08Z, KABY around 10Z, KTLH around 12Z,
and KVLD around 13Z. MVFR cigs are possible across KDHN and KABY
with the frontal passage with lower probabilities at the other sites
as moisture wanes with eastward progression. Gusty northwest winds
expected today with gusts to 20-22 knots. Skies clear later today
through the evening hours.
Winds will increase to advisory levels behind a cold front today
and remain strong into Saturday. Winds at cautionary levels are
possible Saturday night before high pressure settles over the
marine area, keeping winds and seas low from Sunday through
A cold front will move through the region this morning with much
cooler and drier air in its wake through the weekend. Relative
humidity values will drop to near 30 percent across SE Alabama and
southwest Georgia this afternoon which is above critical thresholds.
Relative humidity values will drop even lower Saturday afternoon,
possibly close to 20 percent in spots. However, other necessary red
flag criteria are unlikely to be met.
No rain is expected over the next several days, thus there are no
