.DISCUSSION...

This afternoon through Friday: Storms have developed over eastern
MS in an environment with steep lapse rates and high DCAPE values
supportive of downburst potential. As the storms continue to
move/propagate southwest/west into a hot and unstable airmass
through the late aftn and early evening, they should become
better organized and may bring the potential for a greater wind
threat to much of the remainder of the forecast area. Storms
should diminish with sunset, but expect a lingering shower/storm
threat into the overnight as cyclonic flow aloft continues.

Given a similar weather pattern for Friday with the forecast area
located between the upper low to our east upper ridge to our west,
we'll likely see a repeat of storm development with daytime
heating. This may raise concern for damaging downbursts again, but
there is still some conditional aspect on how things will evolve
tomorrow based on how much coverage we ultimately end up with
today. /EC/

Friday night through Thursday: A large upper-level closed low
will begin to lift north east and open up into an elongated trough
over the southeast while simultaneously pushing a midlevel short
wave across the Lower Mississippi Valley. While mid and upper
level flow will remain more modest, diurnally driven showers and
thunderstorms will be possible Saturday. Long range models(GFS &
ECMWF) continue to struggle with placement of precipitation and
which days we will be dry through out the extended period. The GFS
puts a possible MCS across the southwest early Sunday morning and
again across the north Monday afternoon while the ECMWF remains
dry. By Monday evening both models begin to build in mid level
ridging. So with this much difference in PoPs and the agreement of
a ridge building in next week, stuck with the dry NBM blend
Monday through next Thursday. High temperatures will range from
the upper 80s to low 90s throughout the period./JNE/

.AVIATION...
18Z TAF discussion:

VFR conditions will prevail for the most part outside of SHRA/TSRA
activity through the forecast period, which should be most
prevalent during the afternoon/evening. There could also be LIFR
category stratus and fog concerns during the early morning in
primarily the PIB/HBG area. Otherwise, expect surface wind to be
light. /EC/
