...Windy Conditions Today Then Turning Cold Tonight...

.An upper low will swing through the area today, allowing winds
to pick up to around 20 to 30 mph with higher gusts. These winds
will calm down quite substantially this evening and the colder
airmass will begin to settle down into the area. This puts the
northern half of the area generally at or below freezing. Further
south, temperatures will stay above freezing for most of the area
but will still be in the low to mid 30s. Dewpoints will remain
above 30 in these areas so patchy frost is possible. There could
be a few spots in the south that drop to 32 degrees but those
will be more isolated than across the north.

Area Forecast Discussion...UPDATED
National Weather Service Birmingham AL
1202 AM CDT Mon Mar 12 2018

.UPDATE...
Aviation Discussion.

&&

.SHORT TERM...
Through Tonight.

Area of showers is moving west to east across Central Alabama this
evening, ahead of a cold front. Now seeing northwesterly winds at
Haleyville and Tuscaloosa, with wind gusts up to 25-30 mph.
Anticipate the front moving through the Birmingham metro and an
increase in winds within the hour.

Forecast thinking overnight has not changed from this afternoon.
Colder, drier air will filter into the area behind the front, as
an upper level trough moves across the region. Most of the wrap
around moisture will remain north of Central Alabama late
tonight/early Monday morning. If a few showers do move through the
northern portion of the area, profiles just off the surface will
be cold enough to support a light rain/snow shower. Chances are
low and uncertainty high, and will only carry slight chance to
chance wording. Ground temperatures are too warm for any
accumulation, and no impacts from any light snow showers/flurries
are expected.

14

Previous short-term discussion:
Tonight through Monday.

--Continued cloudiness with another opportunity for showers
 tonight; clearing sky and chilly breezes on Monday--

At 20:30Z/3:30PM, GOES-16 water vapor showed an upper trough over
MO, which is forecast to move through the region tonight/into
early Monday and eventually aid in a deepening surface low, turned
Nor'easter, off the Eastern U.S. coastline. The upper trough will
push a front/associated rain showers through Central Alabama
tonight, with wrap-around moisture across the comma head region
centered over the TN Valley.

This is a cold upper trough, with a good envelope of low-level/850mb
cold advection as well. Temperature profiles (excluding the surface)
are progged to fall below 0C/32F tonight in a northwest-to-southeast
fashion late overnight-early Monday morning, before moderating a
touch through Monday. This is only worth mentioning given the
potential for wrap-around moisture. Right now, assuming the track
and pivot of the upper trough/low, there's just a slim chance that
there'd be spotty light precipitation reaching this far south, and
overlapping the period of cold air, as the bulk of deeper
moisture/precipitation remains well toward the north/northeast.
If an overlap were to occur, a snow flurry would be possible
early Monday morning, limited to the northeasternmost points of
the forecast area. Impacts are not expected. Low temperatures
should be around the mid-upper 30s north to low-mid 40s south.

Drier air will steadily advect into the region behind the departing
upper trough/low, which will erode our overcast cloud deck from west-
to-east and yield sunshine all areas by/into Monday afternoon.
Northwesterly breezes will increase overnight behind the frontal
passage, and last through the day due to a pressure gradient between
the deepening downstream surface low and upstream surface high.
Gusty winds will relax around sunset. High temperatures will be in
the 50s area-wide, perhaps some pockets of upper 40s in higher
terrain.

*Right now, winds (sustained and gusts) are just shy of Wind
Advisory criteria; however, we'll need to take another look during
the next 1-2 shifts for possible issuance for Monday, especially
across the eastern part of the CWA where the pressure gradient will
be highest (even more-so farther east).

89^GSatterwhite

.LONG TERM...
Tuesday through Saturday.

High pressure will build into the area behind the upper low on
the backside of the eastern CONUS trough. This will help provide
the area with another shot of colder air through the end of the
week. At this time it looks like Wednesday and Thursday mornings
will be the coldest with another widespread freeze/frost across
the area. Continued to go below model blends by a few degrees as
there will likely be some radiational cooling that the models have
a hard time at calculating.

With such an amplified trough in the east, there will be an
equally amplified ridge developing to our west. This system will
slide into the area by Friday and we will see warmer temperatures
and the approach of the next system that will likely work into
the area by next weekend. Will need to monitor the model trends on
this system as warmer temperatures could allow for better
dynamics to work into the area increasing a severe risk, but at
this time there are too many uncertainties. So overall, look for
drier and cooler temperatures through midweek and then a modified
airmass will move into the area with more Spring-like temperatures
by the end of the week.

.AVIATION...
06Z TAF Discussion.

Area of rain is moving eastward tonight, affecting most locations
along and east of the I-65 corridor. Heaviest rain will not impact
forecast terminals. MVFR cigs expected overnight, but cannot rule
out occasional drops to IFR cig. The exception is TOI, where
rainfall will stay north of the site, and fog/low clouds has brought
conditions down to LIFR.

As the front continues to push across the area, northwesterly winds
will increase significantly. Speeds should average 16-21 knots, at
least, with gusts between 25-30 knots through Monday before relaxing
around sunset. Stronger winds will help prevent category drops
overnight, and will bring the cig and vis at TOI up to IFR/MVFR.

Drier air will advect into the region behind the front, causing
rising cloud bases and an eventual clearing sky/return to VFR Monday
afternoon.

14

&&

.FIRE WEATHER...

Showers and storms to impact the area during the day and into
tonight. Rain finally ends on the day Monday with dry conditions
through the much of next week. Visibilities will be restricted at
times due to the rain, but fog is not expected to be a big impact
through Sunday. KBDI values remain very low due to recent rainfall
and will likely remain that way with the upcoming rains, so there
are no fire weather concerns.
