Synopsis for pascagoula to atchafalaya river out 60 nm -
high pressure is slowly pushing south and will become remain centered over the lower ms valley late tonight and early tomorrow before sliding over towards the ohio and tn valleys Wednesday. This will finally allow winds to slack off quickly tomorow while veering around from northerly tonight to easterly by Wednesday. Winds will also increase Wednesday with headlines likely being needed Wednesday night and Thursday as a surface low develops and slides across the gulf.

SHORT TERM
(This evening through Tuesday night)
Issued at 417 PM CST Mon Jan 13 2025
Rain and moisture quickly pushed out to the southeast and we have generally seen mostly sunny skies. Even with some slight CAA through the day we have not seen cold weather cu develop. This allowed temps to get much warmer than anticipated with lower 60s across portions of the area.
The forecast for the next 48 hours is relatively quiet as the next possible impacts really don't show up till maybe overnight Wednesday and more so this weekend. So the interesting this with our system yesterday and last night is there was never any real trough axis sliding through. The rain was driven by a sfc low sliding across the northern Gulf under WSW flow aloft. With the (saying this loosely)
L/W trough highly positively tilted from the central Canadian/US border to the southwest through the 4 corners and into the Pacific off the srn CA coast it has maintained that broad WSW flow. This is not going to change over the next few days as another system dropping down the Pac coast will continue to anchor the base of the trough back to the southwest tonight. This feature closes off and eventually cuts off west of the Baja with a possible Rex Block trying to develop Wednesday over the ern Pac and west coast. This begins to lead to more of a zonal flow aloft with a potent s/w dropping southeast over top of the Rex Block and into the srn Plains states Wednesday night and could lead to rain returning much earlier than previously thought but more on that in the long term.
So for the next few days we look quiet and cool. There is still some weak CAA expected to occur over the next 18-24 hours and tomorrow could be slightly cooler than today. But with no real LL thermal trough seen in the models that cold weather stratus deck that was a possible concern today and possible lingering into tonight is no longer an issue. We should have no problem cooling off and a light freeze is possible across southwest MS and just across the border into the FL parishes but farther south towards I-12 lows probably remain in the mid to upper 30s and mainly due to some mixing still.
Light CAA taking place overnight in the LL will help keep winds up a little and thus some mixing and not allowing for optimal radiational cooling. That may be a lot better tomorrow night and could allow for a few locations in the river drainage basins to cool off to near freezing. That said with the winds up tonight, especially across the northshore as winds will mix more efficiently coming off the lake, wind chill values will range from the mid 20s in southwest MS to upper 20s and lower 30s down to I-12 and across coastal MS and then lower to mid 30s along and south of I-10 in SELA.
As we mentioned earlier there is still likely to be some mild CAA in the LL and mdls show h925 temps dipping a little early tomorrow and this may lead to highs generally in the 50s across the area. Again this will actually be a few degrees cooler as many sites did peak out in the lower 60s today. Another cool night Tuesday night but we should be a few degrees warmer as LL temps look to start slowly warming as we head into Tuesday evening. We may also have some thin cirrus across the region. /CAB/
LONG TERM
(Wednesday through Sunday night)
Issued at 417 PM CST Mon Jan 13 2025
Confidence is not extremely high in the extended forecast.
Initial thoughts were we should remain dry until the next system next weekend but now there has been a large shift towards rain returning as early as overnight Wednesday night. This appears to have a lot to do with the disturbance currently southwest of CA and the abundant energy dropping down the coast into it. As that happens as was mentioned earlier it will close off and eventually cut off late Tuesday night/early Wednesday. Because of this the WSW flow aloft becomes more zonal as it is in response to another strong disturbance dropping south over the Continental Divide which will move into the srn Plains late Wednesday. Depending on how strong/deep this disturbance is we will see some type of response in the Gulf with either an actual sfc low Wednesday night over the northwestern/north-central Gulf or a weaker wave a little farther south over the western Gulf. Both options bring about the possibility of rain early Thursday but the slightly farther north and more well developed solution has light rain during the over night hours spreading in from the southwest/west and likely light rain through most of the day leading a rather cool and dreary day Thursday. NBM is a little off as it doesn't have real high PoPs but it holds onto rain through Friday which neither of the previous solutions show. Given this is the first real trend towards better rain chances for Thursday we will stick closely to the NBM for now but given the amount of lift aloft and that fact that we did not have a true trough pass through and thus never completely cleaned out the environment and moisture will be just to our south am more inclined to believe the trend towards a wetter scenario for overnight Wednesday through Thursday...fairly similar to the past 24- 36 hours where models were dry 3-4 days out and then progressively got wetter.
Next more bona fide system will be this weekend with the L/W trough becoming more amplified as the short lived Rex Block breaks down quickly (blocking pattern don't typically break down quickly but then again we are in winter and have been in an active pattern for almost a month now). There may be some embedded thunderstorms as instability will still be very very limited but likely stuck much closer to the coast. Heading into next week we will see another significant cool down and lets see how things transpire and if there is another 1 or 2 southern winter systems. /CAB/

Conditions rapidly improving across the area. Low cigs are finally pushing southeast and becoming SCT to FEW with only some wispy cirrus blowing over from the southwest. Winds are breezy out of the north but should begin to slack off around sunset for all but MSY and NEW that will see enhanced mixing overnight thanks to the Lake. Once the last of the low clouds mixes/moves out VFR conditions are expected to persist through the rest of the forecast. /CAB/
