826 FXUS64 KLIX 232134AFDLIXArea Forecast DiscussionNational Weather Service New Orleans LA334 PM CST Thu Jan 23 2025...New SHORT TERM, LONG TERM, AVIATION, MARINE....SHORT TERM...(This evening through Friday night)Issued at 327 PM CST Thu Jan 23 2025Finally much of the area was able to climb into the mid 40s to lower 50s. This definitely had an impact on the snow and ice over the area. Many locations that have been shaded from the sun though are still holding onto the snow and will take another day maybe even a second to completely get rid of but by tomorrow afternoon we should be almost snow/ice free.Even though the snow and ice is melting and evaporating we are still going to be chilly. The trough axis is off to our northwest and will swing through the Lower MS Valley tomorrow. But we quickly move into zonal flow as the mid lvl flatten out across the central and eastern CONUS. This will bring about a progressive pattern into the area and we will see big difference this weekend from where we were 36 hours ago. High pressure builds in tonight with light northerly winds still in place. The cirrus that was streaming over the area is pulling away to the east and a decent radiational cooling night is in store. Now we will not be anywhere close to what we saw the previous 3 nights but it will still be a cold one with dewpoints tanking into teens and mid 20s. Lows tonight will drop towards and moderate to hard freeze across much of the area. Winds will be fairly light tonight but still around 4-6 mph out of the north, especially south and southwest of the tidal lakes. This will present slightly colder wind chills tonight than the actual temperature. With actual lows and/or wind chills drop down to or below 25 again tonight across the entire area we issued another Cold Weather Advisory for all areas along and south of I-10/12. Temperatures will climb above freezing even faster tomorrow morning with highs in the mid 40s to lower 50s. Friday night could actually be slightly colder than tonight for the northern and especially areas east of I-59. High pressure will be directly centered over the area going into the evening but it will slowly slide northeast through the night. This will allow the ridge to wedge into the area from the northeast and usually very favorable for cold air drainage across the area. This should lead to the PAscagoula and Pearl drainage areas to drop quite a bit again with another night of light to hard freezes across the region. /CAB/&&.LONG TERM...(Saturday through Wednesday night)Issued at 327 PM CST Thu Jan 23 2025Heading into the weekend we will start moderating and seeing the moisture recover over the area. The zonal flow aloft will likely send one or two subtle impulses across the area late this weekend and into the new work week. That along with an inverted trough draped across the Lower MS Valley Sunday night and into Monday may spark showers and perhaps one or two rumbles of thunder but that is not looking too likely. With the fast zonal flow overhead we will slowly moderate through the work week with mid to upper 60s expected by Tuesday and even a few 70s by Wednesday. Morning lows will also slowly climb with mid 40s to lower 50s Tuesday morning and upper 40s to mid 50s by Wednesday. Next shot for some decent rain looks to be late in the week as a potent closed low tries to work east across the 4 corners. /CAB/&&.AVIATION...(18Z TAFS) Issued at 327 PM CST Thu Jan 23 2025Unless there is some very shallow ground fog/freezing fog duringthe early morning hours there should be no concerns. Confidence istoo low to carry FZFG or FG at this time. Other than that VFRcondtiions will persiste with winds slowly adjusting fromnorhterly tonight to light and vrb or out of the east middaytomorrow. /CAB/&&.MARINE...Issued at 327 PM CST Thu Jan 23 2025High pressure will dominate the region but with it still centeredoff to the WNW tonight northerly to northeasterly winds willcontinue to and could approach 12 to 15 kts over the outer waters,especially west of the mouth of the river. High rpessure thismoves directly over the area tomorrow and continues to push NEovernight with return flow trying to quickly set back up Saturdaymorning. /CAB/&&.PRELIMINARY POINT TEMPS/POPS...MCB 23 47 22 54 / 0 0 0 0 BTR 25 50 25 58 / 0 0 0 0 ASD 25 51 24 56 / 0 0 0 0 MSY 31 49 31 56 / 0 0 0 0 GPT 26 48 26 53 / 0 0 0 0 PQL 22 51 23 56 / 0 0 0 0 &&.LIX WATCHES/WARNINGS/ADVISORIES...LA...Cold Weather Advisory from 10 PM this evening to 9 AM CST Friday for LAZ046>048-056>060-064>070-076>090.GM...None.MS...Cold Weather Advisory from 10 PM this evening to 9 AM CST Friday for MSZ083>088.GM...None.&&$$SHORT TERM...CABLONG TERM....CABAVIATION...CABMARINE...CAB
