.SHORT TERM...

Very little change expected in the temperature department
overnight. Low clouds will remain socked in at most locations
holding the temperatures close to where they are now. Lows in the
40s north and central, 60s southeast. Rain has diminished for the
most part at the time being. Some drizzle still showing up from
time to time. There may be some redevelopment of some showers and
this will be handled shortly with the early morning update.

Dense fog will also be an issue. Currently have all but the
southeast in the advisory. Will have to keep an eye on those areas
to make sure nothing develops there too. The quasi-stationary
front is hung up in the area too. 

75

Previous short-term discussion:
A quasi-stationary front was located near TOI and EUF early this
evening. The front really made no progress northward as a weak
wave moved along it this afternoon. This front will continue to
meander across the far southern reaches of the area tonight and
Monday. Quite an airmass difference across the front with highs in
the 40s north and 70s southeast. South to west winds will
continue in the lower levels just above the front. This moisture
will ride over a relatively cool airmass and low clouds and fog
are expected. Some of the fog will become dense at times, with
visibilities 1/2 mile or less. Will hold off on an advisory at
this time and try to narrow down an area better. An advisory may
become necessary and will monitor observations closely for a later
update. Rain will remain possible close to the front south with
drizzle north.

75

Previous short-term discussion:
Light rain with a few pockets of moderate rain continues to
overspread the area as a weak surface boundary sets up across the
southern half of the state. The rain should gradually end from
west to east through the late afternoon and evening hours as the
boundary weakens and stalls to the south. It is likely that the
steady light rain will become more showery and drizzle through the
overnight as low clouds and some patchy dense fog develops. 
Expect this pattern to continue until the next potent shortwave 
ejects from the west early Wednesday.

17/KLAWS

.LONG TERM...
Monday through Sunday:

Monday/Monday night:

Southwesterly anti-cyclonic flow will be in place on Monday around
deep layer ridging centered between Florida and Cuba. A split flow
pattern will remain in place with a southern cutoff low over the
Desert Southwest and northern stream troughing over Canada. A
precipitation-reinforced quasi-stationary front will extend from
the Louisiana Gulf Coast northeastward toward southeast Alabama.
The eastern portion of this boundary may drift southward during 
the morning following passage of a weak meso-low. Precipitation 
forecast remains challenging due to weak/broad forcing associated 
with weak waves in the southwest flow, and how quickly a residual 
cold pool/area of dry air erodes in the wake of today's activity. 
Showers and thunderstorms will develop late tonight/early tomorrow
morning along the frontal boundary in the vicinity of the 
Louisiana Gulf Coast in a broad area of upper-level lift 
associated with the right entrance region of an upper-level jet 
streak and lift to the east-northeast. Generally favor a non-GFS 
solution with a further south position of the front due to outflow
from today's activity and highest rain chances closer to the Gulf
Coast with some activity bleeding over into our southern 
counties. A separate area of mid-level frontogenesis and moisture 
will located further north closer to the I-20 corridor, which 
could allow for some rain to fall there as well if low-level dry 
air can be overcome. So, kept a mention of scattered showers in as
far north as Birmingham with lower confidence. Weak elevated 
instability will be in place across the southern counties which 
could allow for a rumble or two of thunder, but any surface-based 
instability and potential for any stronger storms should remain 
south of the forecast area. Also not expecting any heavy rain 
during this time. Temperatures will hinge on precipitation and 
lingering cool air. Will indicate highs in the upper 50s to low 
60s north and mid to upper 60s south (low 70s possible far 
southeast), but confidence is low as some high-res guidance keeps 
temperatures across the north in the low 50s. 

Some showers may linger near the I-20 corridor through the
evening. Focus for showers shifts to the northwest after midnight
as low-level isentropic lift strengthens ahead of the cutoff low
ejecting out of West Texas, and as the front lifts northward as a
warm front. This also results in a non-diurnal temperature trend
with temperatures steady/rising slightly after midnight.

Tuesday/Wednesday:

Models indicate a west to east band of moderate to heavy rainfall
developing along and north of the warm front as unseasonably high
PWATs intersect the boundary. This area of heavy rain has been
trending northward, so the main threat of flooding seems to be
shifting north of the forecast area, but will continue to 
monitor. The strong shortwave will move through the area late 
Tuesday night and Wednesday morning while getting squeezed between
the subtropical ridge and troughing over the northeastern CONUS. 
Models seem to be converging on the forecast area being in the 
warm sector of a surface low moving across northern Mississippi 
and middle Tennessee with low to mid 60s dewpoints and a few 
hundred J/kg of CAPE ahead of a cold front/dry-line like feature. 
There are still some key differences regarding the strength of the
low and associated backing of the low-level winds, and how soon 
the low-level winds will veer out relative to the instability 
arriving. If trends continue, a threat for isolated tornadoes late
Tuesday night and Wednesday morning could be added to the HWO in 
later issuances given favorable wind profiles for mini-supercells.

Thursday through Sunday:

One dry day is expected on Thursday between systems with the only
forecast challenge being a possible wedge briefly trying to build
in. Focus then shifts to the next southern-stream trough ejecting
out of the western CONUS, and eventually phasing with a deep
northern stream trough engulfing almost the entire CONUS. Another
cold front looks to move into the area during the Friday/Friday
night timeframe. Any threat for severe weather will depend on the
degree of moisture return in the wake of Wednesday's system.
Models and ensembles have had many varying solutions for this 
weekend regarding whether the front moves through, stalls, or 
retreats off to the northwest, and whether the expected outbreak 
of arctic air catches up to precipitation along the front. It's
certainly too early to use any deterministic model runs at this
point. General consensus continues to support only mentioning
liquid precipitation through the current forecast period at this
time.
