.AVIATION...
00Z TAF discussion: IFR/MVFR conditions will continue through the
evening as MCS continues to move through the area. The widespread
precipitation will become more showery after midnight, but low
clouds will keep MVFR ceilings continuing overnight into
Thursday./GG/

&&

.DISCUSSION...

Tonight through tomorrow night...showers and thunderstorms are
moving into the area as a strong upper trough and associated cold
front approach. Some of these storms are severe and expect this
activity to move into our area this afternoon and evening. Little
has changed as far as the severe potential, with the Highway 84
corridor continuing to look like the area with the best potential
for severe storms. Also, a tornado watch is already in affect for
these areas into this evening. The severe risk will end later this
evening with the cold front exiting the area soon after midnight.
Showers will continue to be possible into the overnight hours,
but will end in the northeast very early on Thursday.

Cooler air will usher in behind the boundary, with highs on Thursday
ranging from the low 60s in the Delta to around 70 across the Pine
Belt. Much of the day will be dry across the ArkLaMiss, but upper
troughing will deepen over the area on Thursday, with increasing
chances for light rain starting by the late afternoon, especially
for areas north of I-20. /15/

Thursday night through Tuesday night: a closed upper low will
slowly cross the lower to middle MS Valley region and reach the
Appalachians by this weekend. As this happen, cyclonic flow
around the western periphery of the low will maintain a long
stretch of considerable cloudiness and cool daytime temperatures
along with areas of light rain/drizzle over mainly northern
portions of the forecast area. As the upper low continues to pull
away, we'll see a dry weather pattern resume with much milder
daytime temperatures going through early next week. /EC/
