Cumulative rainfall for 2024 from the start of the year through mid September was generally above average with just a few times dropping down to average. However, from mid September through the entire month of October, virtually no appreciable rain fell.

The episode as NWS LIX wrote it up.
Cumulative rainfall for 2024 from the start of the year through mid September was generally above average with just a few times dropping down to average. However, from mid September through the entire month of October, virtually no appreciable rain fell. A few rain events in November and early December helped some, but the amounts were not enough to make up the deficit from average. It wasn't until the end of December that a rain event that dropped around 6 inches of rain brought Jackson County out of D2 drought conditions.

(This evening through Sunday night)
Issued at 240 PM CST Sat Nov 30 2024
After a chilly start this morning much of the area warmed up into
the mid 50s to lower 60s under sunny skies providing a very
pleasant end to November. As dry as it is across the area we will
cool very quickly tonight as radiational cooling conditions should
be rather optimal.
Through Monday the biggest forecast problem is going to be
temperatures and who all reaches freezing. High pressure is
already building in should remain mostly over the area through the
evening but overnight it will slowly slide east. That said it
will still wedge southwest through the area which is usually a
great setup for the drainage areas. Combine that with rather dry
conditions, dewpoints have dropped into the lower to mid 20s
across most of the area along and north of the I-10(coastal
MS)/12(SELA)corridor. Along the immediate coast and south of I-12
in SELA dewpoints are as high as the upper 30s and lower 40s. With
high pressure providing light winds and dry BL conditions the
other two things that could impact are clouds and if there is any
WAA in the LLs. Both are yes but not overwhelming though. The WAA
is negligible overnight as the models suggest most of the WAA at
h925 is already occurring and slowing significantly after 3z.
While h85 temps are generally steady the entire time. This should
not hurt radiational cooling so clouds now. Like last night cirrus
could stream in across the area and there is some possible
thicker cirrus streaming across northwestern Mexico and into
western TX. This may move in overnight tonight but it may also be
a little farther south than what was expected. It also appears to
be not as thick as the cirrus that was possible last night. With
only thin to possibly moderate cirrus overhead and everything else
being optimal cooling tonight should be fairly good across the
northeast half of the CWA. With that we have issued another Freeze
Warning including all of southwest MS and coastal MS. Portions of
SELA in the warning will be east and north of a line from East
Feliciana through Hammond and east across the immediate
Northshore. If clouds remain thin some other locations just
outside of the warning could approach freezing but given the tight
dewpoint gradient along the River parishes cooling fast enough
this evening may not be as efficient.
A L/W trough over the eastern CONUS will not be going anywhere for
a little while and this will keep the area in northwest flow
aloft. With that a reinforcing cold front will move through late
tomorrow. This won't necessarily usher in drier or cooler air but
it will keep the region from moderating with highs Sunday and
Monday only a few degrees warmer than todays.
This will also allow a few areas to test freezing once again but
with last nights freezing temps and if much of the area gets to
freezing tonight that is in the warning there may not be a freeze
warning issued for Sunday night/Monday morning for some locations
given that they will have already had a few freezes. /CAB/

.LONG TERM...
(Monday through Friday night)
Issued at 240 PM CST Sat Nov 30 2024
The extended portion of the forecast is a little more active but
confidence is not very high. Models are struggling with how to
handle the Rex Block over the Pacific coast. The very cold air
mass over western Canada will surge south but as feared given the
L/W troughs location much of that colder air will get shunted to
the northeast of the region. Overall not as much adjustments made
to the forecast from the NBM.
Monday night through Tuesday night should be the last chance for
well below normal temps for atleast the rest of the work week. The
L/W trough will slowly work east with the trough axis just off the
Atlantic coast possibly by Thursday. The low at the base of the
Rex Block well begin to slide east a tad before becoming elongated
from the 4 corners and to the southwest into the Pacific while s/w
ridging will develop just to the east of it over the southern
Plains. This will lead to more of a zonal flow over head Wednesday
night and through Friday. By Wednesday we should begin to moderate
quickly with return flow as high pressure at the sfc slides east
and weak cyclogenesis is expected along the lower and middle TX
coast. That low will likely remain weak but it will move north and
then northeast into Lower MS Valley Thursday. At the same time we
will likely see a few subtle impulses in mean flow try to move
through the area and that will likely help to develops some
showers and possibly a few embedded thunderstorms. /CAB/

High pressure building in through tonight will keep winds on the
light side across the coastal waters. Winds will become more
easterly tonight before a reinforcing frontal passage Sunday
backing winds out of the northeast until mid week. Return flow
should begin to get started as high pressure moves east and weak
low pressure develops across the lower and middle TX coast. /CAB/
