884 FXUS64 KJAN 231558 AFDJAN Area Forecast Discussion National Weather Service Jackson MS 958 AM CST Sun Feb 23 2025 ...New MESOSCALE UPDATE... .MESOSCALE UPDATE... Issued at 949 AM CST Sun Feb 23 2025 The forecast remains on track with rain being reported at most sites at and south of I-20 in response to a low amplitude trough moving through the area. Rainfall rates are not expected to reach flood stage this afternoon. Highs will crest in the high 40s for sites south of Highway 82 and peak just above 50 north of Highway 82./OAJ/ && .DISCUSSION... Issued at 415 AM CST Sun Feb 23 2025 Today through tonight: Rain is increasing early this morning over western and southern portions of the forecast area as a low- amplitude shortwave trough quickly approaches from the west in the fast zonal flow aloft. Rain will continue to increase this morning and should reach peak coverage this afternoon, before diminishing this evening. This will be a chilly, soaking rainfall event with one to two inch amounts common along/south of the highway 84 corridor, up to one inch amounts along the I-20 corridor, and lighter amounts farther north. Convective rainfall will be minimal, and this will limit any potential for excessive rainfall rates that could result in flash flooding. The system will move out and rain should end over eastern portions of the area prior to daybreak, at which time we`ll most likely need to monitor for some fog potential. /EC/ Monday through next weekend: Temperatures will moderate in the longer term with a fairly quiet pattern in the upcoming week. W/NW flow aloft will promote fairly dry conditions with near to slightly above normal temperatures. Ridging will build Tuesday into Wednesday and bring a brief warm up early to mid week, with temperatures warming into the 70s. By Thursday, an upper trough and associated surface cold front will push in from the north and bring temperatures back to normal for the remainder of the week. This front could bring a few showers and isolated thunderstorms Wednesday night into Thursday, but overall the airmass in its wake is rather dry, so rain should shut off fairly quickly. High pressure becomes reestablished by Friday/Saturday and will allow a return of highs in the 70s for the weekend./SAS/ && .AVIATION... (12Z TAFS) Issued at 553 AM CST Sun Feb 23 2025 Conditions will deteriorate through today, with widespread IFR/LIFR stratus and reduced vsby due to RA/SHRA by late afternoon along/south of the I-20 corridor. Rain will end from west to east tonight, but widespread IFR/LIFR stratus will continue until early Monday morning, when fog will also become a possibility. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
