SYNOPSIS.

Upper low early this morning looks to be in the vicinity of Jackson, MS. Upper ridging along the Pacific Coast, with a weaker upper low well to the west of Los Angeles. At the surface, low pressure appears to be centered over western Alabama. Radars and surface observations aren't indicating any precipitation over or near our CWA at this time. That being said, wouldn't be out of the question for radars from KLIX/KDGX/KPOE to be shooting above any snow flurries or sprinkles over SW Mississippi, as the beams are around 9000-12000 feet over Wilkinson County. Temperatures were generally in the 30s at 3 AM CST, with breezy to windy conditions.

SHORT TERM (through Tuesday night).

Will hold onto the Wind Advisory for now south of Lake Pontchartrain, although not seeing a lot of observations sustaining 25 mph at this time.

Really the only forecast issues in the short term will be today, with the low end potential of some snow flurries north, and the timing of clearing later in the day, with it's associated impact on high temperatures.

Upper low appears to be at the base of the longwave trough and should begin to lift northeastward this morning. Some question as to how saturated the airmass is over southwest Mississippi. The special 06z LIX sounding showed the airmass pretty much bone dry above 5000 feet, and questionable whether it's cold enough to promote snowfall. The JAN sounding at the same time showed a healthy saturated layer from about 3000 to 10000 feet and cold enough to support snow. Water Vapor imagery does show that the dry slot is likely to exit the southwest Mississippi area in the next few hours. Will assume that the moist layer over southwest Mississippi will be somewhere in the middle of the 2 soundings, say at about 7000-8000 feet. Will continue the possibility of a few snow flurries across southwest Mississippi through mid morning, but at this time, don't anticipate major impacts.

Low confidence in any significant clearing much prior to sunset with a cold upper low and low level thermal troughing in the area. If there's a preferred area for clearing prior to late afternoon, it'd probably be the southwest third of the area, say west of a Baton Rouge to Grand Isle line. Trending on the cool side of guidance for highs today.

Once the low starts pulling out today, high pressure will build in from the west. By Tuesday afternoon, it will be centered over the Carolinas with onshore flow returning locally. Beyond this evening, don't expect much in the way of clouds, let alone precipitation until Tuesday night. NBM and operational model guidance numbers generally in the same ballpark for tonight through Tuesday night, so really no significant targets of opportunity to make any real improvements in the temperature forecast. 35

LONG TERM (Wednesday and beyond).

After a few dry days, this portion of the forecast period will be the beginning of a relatively wet period. Zonal upper level pattern over the southeast will be transitioning into troughing as one dives south out of Canada on Wednesday. A cold front associated with this feature will just be moving into northern LA/MS midday, which means it wouldn't be reaching the CWA until late afternoon and into the evening hours. The same goes for rainfall from this system. A swath of showers and a few thunderstorms, mostly post frontal, will steadily be tracking southeast across the local area Wednesday evening and generally pushing offshore by Thursday morning. At least thats what the GFS indicates. The ECMWF suggests continued isentropic lift behind the front which will keep rain going through Thursday. NBM carrying a fair portion of its POP weight on the ECMWF. GFS performance has been better for quite some time and wouldn't be surprised if its solution does better with this forecast period. Regardless, drastic drop in temps expected with this frontal passage. After mid to possibly even upper 70s on Wednesday, highs will struggle to reach the 50s in some locations on Thursday. A series of reinforcing troughs look to maintain below normal temp pattern through the weekend with low, but non-zero, rain chances. Will need to monitor for frozen precip chances if cold stays in place while shortwaves pass through. For now, in coordination with WFO MOB, trending toward a somewhat drier solution than the NBM for next weekend.

MEFFER/35

AVIATION (12z TAF package).

Most observed ceilings sitting just above FL030 this morning, but am seeing MVFR conditions at KGPT and KMCB, and noted upstream. Also will need to monitor the potential for -SHSN through mid- morning, mainly at KMCB. Don't expect major impacts, although have noted 4SM at KHEZ in the last hour with some potential for brief ceilings around FL010. Prevailing conditions during the day are likely to be MVFR to VFR ceilings, which should exit around 00z Monday. Winds will also continue to be an issue, with gusts in the 20-30 knot range possible for a good portion of the day. Gusts higher than 30 knots still possible downwind of Lake Pontchartrain at KMSY and KNEW through late afternoon/early evening. 35

MARINE.

Will hold onto the Gale Warning for now, and allow day shift to pare it back, or replace it with a Small Craft Advisory as conditions dictate. May be able to drop the lakes and sounds prior to the 21z CWF issuance, but doubtful it happens much before that. Small Craft Advisories will likely be necessary for about 12 hours after the Gale Warnings. Conditions should relax Monday and Tuesday, with moderate onshore flow returning by Wednesday. With the passage of a new cold front Wednesday night into Thursday, Small Craft Advisories are likely to again become necessary. Those may need to be continued into next weekend. 35
