.SHORT TERM...
(Rest of Tonight)
Issued at 945 PM CST THU NOV 14 2024

This evening on satellite, a swath of post front wrap around
stratus clouds will swing S and E across portions of AL tonight
into early Thu morning. Will be monitoring for fog development,
generally outside of these areas. However, winds are staying up
here and there. This may be enough wind to keep dense fog from
developing tonight. NW-NNW flow behind the system is ushering in
colder air into AL with overnight lows expected to go down into
the 40s for morning lows.

Previous short-term discussion:
(This evening through Friday)
Issued at 237 PM CST THU NOV 14 2024

Clouds continue to clear across the local area in the wake of a
cold front and as sfc high pressure expands east into the
Southeastern CONUS. The upper low responsible for the rain and
cold front will continue to track east off the Atlantic Coast, and
ridging will build over the area as we head into the weekend.
Large scale subsidence will promote dry weather through tomorrow,
with cooler temperatures as highs will be limited to the 60s. The
only potential concern in the short term period will be the
chance for patchy fog development tonight, as cloud cover has
largely cleared the area and recent rainfall has led to saturated
grounds. The main question will be how much cloud cover develops
as a result of wrap-around moisture tied to the aforementioned
upper low, and if the winds will calm enough to support fog
development. Otherwise, overnight lows will be a bit cooler
dropping into the 40s.

.LONG TERM...
(Friday night through next Wednesday)
Issued at 237 PM CST THU NOV 14 2024

Not much change in the long term forecast during the afternoon
update, as conditions remain dry through Monday before upper
troughing shifts east into the MS River Valley and rain chances
increase Tuesday and Wednesday ahead of a cold front. With the sfc
low occluding well before the system nears our area, do not expect
strong to severe storms at this time. Behind this front will be a
much colder airmass, dropping highs into the 50s by Thursday and
lows into the 40s.

Previous long-term discussion:

Ridging, both surface and aloft, will keep conditions dry through
the remainder of the work week and into weekend. Early next week,
bits of shortwave energy will start to eject out of a big longwave
trough in the western part of the country. These impulses will
flatten our ridge a bit, and allowing moisture to creep back up. 00Z
computer model runs now show a surface front arriving here on
Tuesday. Much of the large scale lift will stay to our west and
north, but there is likely to be enough low level convergence along
the slow moving front to cause some showers in central Alabama.
Computer model blend guidance keeps POPs in the forecast through the
remainder of the 7-day forecast period. Looks like some cold weather
is coming as well, although the timing and magnitude of said cold is
still to be determined.

.AVIATION...
(00Z TAFS)
Issued at 635 PM CST THU NOV 14 2024

All TAF sites are behind the front with drier air moving into the
area. There is a large swath of lower level moisture by way of
stratus clouds ~3-6kft to our N that will sag SEWD tonight. Lower
IFR cigs are over GA but those are not expected. Currently the
TAFs are VFR. Will be watching to see how much progress this area
makes. NW-NNW winds are staying up some as well, although they
should not be gusty overnight. Have left fog out for now, but will
be looking to see if it needs to be added for the 6z set.

.FIRE WEATHER...

Rain free conditions will continue through the weekend. 20 ft
winds will remain light through the weekend, generally below
5-7mph. Winds will be northerly on Friday and gradually veer to
the east and southeast through the weekend. Humidity levels will
remain above 40 percent through the weekend.
