Area Forecast Discussion
National Weather Service Jackson MS
328 PM CDT Wed Apr 5 2017
.DISCUSSION...
Today and Tonight...A cold front is working its way
across the area this afternoon. Currently it extends generally along
the Natchez trace Corridor and will exit east of the area early this
evening. The main effect of the boundary is very gusty winds and dry
air. The winds are gusting into the 30 to 35 mph range across the
delta and a wind advisory is already in affect until later this
evening. Although the advisory may expire this evening the surface
gradient will remain strong enough to support gusty winds through
much of the night. Skies will become clear overnight with lows
falling into the mid 40s across most of the area. /15/
Thursday night through Wednesday...
The period will begin with a large cold core low centered over the
Eastern Great Lakes with surface and upper level ridging building in
across the Great Plains. This ridging will continue to build into
the area by Friday into the weekend as the low pulls away off the
New England coast. The surface ridge will become centered over the
lower MS River valley by Friday evening, which will allow for ideal
radiational cooling conditions under clear skies with calm winds.
Temps will be much milder through the end of the work week and into
the weekend with the coldest overnight lows into the upper 30s and
the low 40s on Fri night/Sat morning. By Sat night into Sun the high
will shift east of the area which will allow southerly flow and
moisture return across the area as dewpoints rise back into the 50s.
On Sunday, a trough ejecting out of the Inter-Mountain West will
induce surface cyclogenesis across the Northern Plains and will drag
a cold front south through the Southern Plains. The parent low and
the majority of the forcing and energy will pull away to the east by
Tuesday, thus leaving a slow eastward advancing frontal boundary
across the ArkLaTex. Latest global models are in fairly good
agreement on rain chances returning to the NW portions of the CWA by
Tuesday morning as the frontal boundary continues to move east,
however model solutions diverge shortly after as the GFS washes out
the boundary leaving the best rain chances in the NW while the ECMWF
brings rain into central MS by Wed morning. Thunderstorms will also
be possible with some degree of instability to work with but severe
weather is not expected with very little forcing, shear, and next to
no height falls. While dewpoints will be back into the 60s in
concert with a 330 K ThetaE ridge there's too much uncertainty in
regards to timing and coverage to introduce any flooding potential
in the HWO, especially given that this will be on day 6 and 7. /TW/

.AVIATION...
18Z TAF discussion:
VFR conditions will prevail through the period at TAF sites as a
cold front moves across the area. The main concern will be the
gusty winds as there is a wind advisory in effect for TAF sites
GLH/GWO. The winds are currently out of the SW-W at 10-15 with
gusts to around 20 mph. Gusts to around 30 mph or higher are
likely at most sites this afternoon through the evening hours. The
gusty winds will continue through the night into Thursday morning./15/
