Area Forecast Discussion
National Weather Service Jackson MS
400 AM CST Thu Jan 24 2019

Today and Tonight...As high pressure at the surface settles over the
region, lingering low clouds in the wake of Wednesday`s frontal
passage will continue to shift east and out of the CWA through the
morning. Winds will also ease up, as cooler drier air filters into
the region.  This afternoon, look for mostly sunny skies as highs
range from the middle 40s to lower 50s.

Tonight, a trough axis will swing east through the region. This will
force another cold front southeast and through the forecast area
during the overnight hours.  As a result, a reinforcing shot of cold
dry air will begin advecting southeast into the Lower Mississippi
River Valley early Friday morning, as strong high pressure builds in
from the northwest behind the front. Currently, other than an
increase in clouds, primarily northern portions of the area, no
precipitation will accompany this frontal passage. Lows overnight
will range from the upper 20s to lower 30s. /19/

Friday through Wednesday...

The weather pattern will remain rather chilly through much of the
extended portion of the forecast. The region will remain under
troughing that will also encompass most of the eastern part of the
United States through the weekend. This will lead to cooler than
normal temperatures to start the weekend with a slight warming trend
to more normal temperatures by the end of the weekend into the early
portion of next week.

Our next chance for rain and potentially wintry precipitation will
come around Monday night into Tuesday. A strong front will move
through the region, bringing some at least slight chance to chance
for rain during the evening and overnight on Monday. Once again,
there does look to be some chance that as the cold air moves in, a
mix of rain or snow would occur especially in the northern part of
the forecast area early Tuesday morning. Temperatures will also
plummet through the day with highs Tuesday reaching the mid 30s
across the Highway 82 corridor early before dropping through the
day. Precipitation should move east of the region through the
afternoon, leaving dry conditions in place for much of the remainder
of the week. Chilly temperatures will continue through the rest of
the week as well. /28/


06Z TAF discussion:
Low stratus and some lingering patchy drizzle, left in the wake of
a cold front that`s finally moved east into Alabama, will continue
to clear out of the region from west to east overnight. Until it
does clear, a mix of MVFR/IFR flight categories will be observed
at sites tonight, with KGTR and KMEI likely observing such
categories through perhaps 14-15Z Thursday. Once the low stratus
moves out, VFR flight categories will prevail at TAF sites through
the remainder of this forecast period. Otherwise, winds will
generally be from the northwest throughout the period, between
5-10 knots. /19/
