997 FXUS63 KMPX 181123 AFDMPX Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 523 AM CST Tue Nov 18 2025 .KEY MESSAGES... - Warmer temperatures and dew points has lowered the likelihood of accumulating snow this morning. Thus we have canceled the Winter Weather Advisory. - Rain could still transition over to a wintry mix of snow & sleet this morning over portions of eastern Minnesota & western Wisconsin, but any slushy accumulations are expected to remain under 1". && .DISCUSSION... Issued at 220 AM CST Tue Nov 18 2025 The main question mark for the winter weather potential with this system was whether temperatures would end up a degree or two above/below freezing, & sure enough we are seeing temperatures on the warm end of freezing overnight - with all stations across southern Minnesota reporting rain or a mix of rain & ice pellets so far. Warmer than forecast dew points have been the main culprit, with dew points of 33-35 degrees within the band of rain preventing bulb cooling from reaching the freezing mark. Thus we`ve removed any chance of snowfall accumulation across southern Minnesota, with maybe a light wintry mix of rain, ice pellets, & a few snowflakes through early morning. Slightly farther north towards the US 212/I-94 corridor (mainly the far-southern Twin Cities metro through Eau Claire), we still can`t totally rule out some wintry weather this morning where dew points are currently much cooler & thus could lower wet bulb temperatures to near freezing as the band of precipitation spreads northwards. Any chance for multiple inches of snowfall accumulation looks very unlikely, but a few hours of slushy snow & sleet with accumulations of half an inch to an inch still appears possible once the rain changes over to a wintry mix, generally between 7-10 this morning. Any travel impacts this morning would likely only be limited to lower visibility once the changeover to snow/sleet occurs, so we have opted to drop the Winter Weather Advisory as as surface temperatures will be warm enough to prevent any freezing on the roads. Precipitation could continue to near noon across southeast Minnesota & western Wisconsin, but rising temperatures will likely changeover any light snow or sleet back to rain by late morning. Highs will then warm into the low to mid 40d across central Minnesota & northwest Wisconsin, to the upper 30s across southern Minnesota. For Wednesday, light rain could skirt across central Minnesota during the evening but the bulk of any precipitation will remain over northern Minnesota. Looking ahead, another extended stretch of warm & dry weather looks likely with ensemble guidance suggesting temperature anomalies of 5-10 degrees above normal & low chances for precipitation well into Thanksgiving week. Highs will generally be in the upper 40s to low 50s with lows in the 30s. && .AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/... Issued at 523 AM CST Tue Nov 18 2025 The forecast has ended up on the warmer side of the range of solutions. This has kept the precipitation so far this morning rain rather than snow. For the terminals some snow could mix in at EAU later this morning, otherwise it will most likely stay rain. Generally MVFR ceilings associated with this precipitation. Expect a clearing to VFR afternoon/evening with some lowering ceilings again tonight. Some guidance suggests as low as IFR tonight, but going to give it a few more runs before I am confident in ceilings going that low tonight. KMSP...Overall the terminal area is right on the northern edge of precipitation this morning. So opted to stick with a TEMPO for the morning. While rain is in the vicinity MVFR ceilings are expected. Clearing to VFR this afternoon as everything clears out behind the system. Ceilings to fall again late this evening into tonight. More MVFR ceilings will be possible. /OUTLOOK FOR KMSP/ WED...MVFR, IFR CIGS possible. Wind S 5-10 kts. THU...MVFR. Wind SW bcmg NW 5-10 kts. FRI...VFR.
