. EVENING UPDATE .
Performed a gridded update this evening to reflect radar/obs trends. Main focus ongoing currently is a light band of showers/drizzle parading east across the area. This band is along a 850mb trough/low-level front and associated PVA helping to squeeze out lingering moisture in the low to mid levels. CAM's are not picking up on this much due to how light the returns currently are on radar, but observations are coming in at -RA and prompts enough coverage to manually introduce in the grids through 06Z. However, recent trends since 00Z indicate a downward trend in intensity, still look for some light showers to continue to the east to right before midnight tonight.
Otherwise, low clouds will persist in the wake of this feature tonight, with strong CAA and northerly winds. The big question is how long will low clouds stick around into tomorrow, which may prevent temperatures from warming to suggested model guidance. Using 925mb as a good proxy for low cloud thickness after "some" subtle afternoon mixing (CAM indicating LCL's roughly in this region) places higher LCL RH along and east of I-55. Ofcourse, little 925mb RH is evident in the AM as ceilings/LCL's are below this layer, with lifting likely due to aforementioned mixing by the PM. Will introduce a slight nudge up in cloud cover for now, but not overcast, with thickest cloud potential south of I-10/12 and east of I-55 to marine areas, less clouds to the north. Have reflected this in MaxT's by averaging 2-4 degrees below the blends which places the southshore and coastal MS in the upper 50's. Can't go farther than this due to lack of confidence, but overall still expect a chilly day tomorrow with some intervals of clouds and staying dry. Surface high pressure settles in Wednesday night and into Thursday morning, with maximized radiative cooling processes likely and have once again pulled lows a few degrees below blends with widespread upper 30's likely along/north of I-10/12 to the 40's south to the coast.

SHORT TERM (Tonight through Friday) .
The shortwave trough will continue to move east across the lower Mississippi valley tonight with the associated surface low moving east-northeast across the north central to northeast Gulf coast. The fairly widespread rain will end over eastern/offshore areas this evening. Drier and continued cool conditions will prevail with the sun returning during late morning to midday hours on Wednesday as high pressure builds in behind the front and low pressure area. The surface high will continue to build in on Thursday with a modifying airmass allowing high temperatures to push back up near normal after a cooler than normal period through Wednesday night. The next potent shortwave trough will move southeast through the central Gulf coast region late Friday, Friday night and early Saturday morning. The models depict generally light to moderate rainfall amounts with this system mainly late Friday and Friday night and very few if any thunderstorms.
LONG TERM (Saturday through Tuesday) .
Surface high pressure will be in control with dry and mild weather expected over the weekend. As the surface high shifts east, the next system that may impact our region will be a shortwave trough moving through the western states early in the week. The mentionable rain chances at this point look beyond this forecast period. Temperatures should be near to slightly above normal and rather pleasant for early March.
AVIATION .
00Z TAF FORECAST .
Expect areas of light SHRA and drizzle to persist early this evening, with low CIG's and periodic lower VIS leading to MVFR/IFR conditions. Expect CIG's to continue to lower through the night, with primarily IFR for most terminals through daybreak Wednesday. Low clouds will be slow to break up by Wednesday morning, with a slow clearing expected from north to south. Where clouds remain tight, expect MVFR conditions to persist, otherwise VFR conditions will slowly spread south with SKC and light northerly surface winds. All areas clear out through Wednesday night with prevailing VFR conditions. KLG
MARINE .
Strong north winds near or over 20 knots with higher gusts will continue into tonight. The Small Craft Advisories will remain the same as from the mid morning update. Winds and waves will subside on Wednesday through Thursday as high pressure builds into the region. Yet another weak low pressure system will move across the north Gulf late Friday and Friday night brining another period of moderate to stronger winds and increased wave heights late Friday night through the weekend.
