360 FXUS63 KMPX 270538 AFDMPX Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 1238 AM CDT Fri Jun 27 2025 .KEY MESSAGES... - Another round of rain today may be heavy at times, but the overall flooding threat is less than it was Wednesday. - A threat of severe thunderstorms, including tornadoes, exists across mostly southeastern Minnesota this afternoon. - Another round of strong to severe storms possible Saturday night into Sunday. && .DISCUSSION... Issued at 209 PM CDT Thu Jun 26 2025 Forecast in the short-term calls for similar conditions as to what we saw yesterday. Although this time, the QPF maxima has shifted eastward into southeastern MN and western WI. That being said, radar reflectivity still showing a wide swath of rainfall across MN this afternoon. Rainfall rates appear less intense as observations range between a tenth to a few tenths of an inch since 12z. However, we are monitoring two systems today. The first is a discrete MCV that has made its way across the MN/IA border that is produce heavy rainfall in southern MN. The second is the main low of pressure circulating around SE`rn SD, northern NE. A warm frontal boundary extending from the low shows up well on satellite currently as clearer skies creep into southeastern MN and south/central WI. This is the primary area of concern as we head into the afternoon/evening as the SPC has issued another slight risk for severe weather for these regions. Although seeing the current location of the aforementioned MCV in relation to this frontal boundary will likely confine most severe weather chances east of a line from Freeborn, up to Goodhue, over to Eau Claire Counties. The primary threat once again will be tornadoes as sfc to 6km shear on forecast soundings showing 30-40kts and MuCAPE values exceeding 1500 J/kg. Heavy rain and damaging wind gusts will also be a threat this evening. A tornado watch is in effect until 8 PM tonight. Additional rainfall today looks to exceed an inch however areas in southern MN could receive closer to two additional inches depending on where the strongest convection sets up. With that said, another Flood Watch was issued earlier this morning across southern MN through 1 AM Friday. Should QPF trends northward, the current Flood Watch area may need to be expanded. Heavy rainfall rates between 1 to 2" are possible once again given high tropical-like PWATs nearing 2". One thing to note though is with the lapse of rainfall we saw overnight, this allowed for yesterday`s rain water to recede. Therefore areas across central MN that see more rainfall this afternoon, shouldn`t expect anything beyond ponding in the usual spots. Friday continues to look like a beautiful day. Temperatures will reach the low to mid 70s with dew points near 60 degrees. The "nicer" weather though will be short lived. Saturday, much warmer temperatures and humidity return. Heat headlines may not be needed but heat indices will near the mid 90s especially across southwestern MN. Aside from the hot and humid conditions, another Slight (level 2 of 5) risk for thunderstorms is forecasted for Saturday. A shortwave is expected to move across the Dakotas Saturday which will converge on an already unstable airmass. Impacts are yet to be determined but make sure to make plans accordingly for a potential for severe thunderstorms. Once that passes, things look to quiet down early next week with highs in the low to mid 80s with dew points mainly in the 60s. Active weather returns later in the week. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1222 AM CDT Fri Jun 27 2025 Some pockets of drizzle linger, but the main aviation concern overnight will be the fog and low ceilings. Generally IFR or low MVFR can be expected across the region, with some spots flirting with LIFR at times. These conditions will last through mid morning, with gradual improvement expected the rest of the day. Winds shift from the N/NW to SE by late afternoon, generally at or below 5 kts. KMSP...Going to be right on the line between LIFR and IFR much of the early morning hours. I am leaning more confidently towards IFR prevailing, but it is reasonable to expect at least FEW-SCT cigs below 500 ft through around 14-16z. /OUTLOOK FOR KMSP/ SAT...Mainly VFR. Chc PM TSRA/MVFR. Wind S 8-12 kts. SUN...MVFR/RA likely, chc TSRA/IFR. Wind SW 5-10 kts. MON...VFR.Wind NW 10-15 kts. && .MPX WATCHES/WARNINGS/ADVISORIES... MN...None. WI...None. && $$ DISCUSSION...Dunleavy AVIATION...BED
