Area forecast discussion, May 25, 7:13 AM CDT, 3 hours 48 minutes before
Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 713 AM CDT Mon May 25 2020 .Updated for 12Z Aviation Discussion... Issued at 701 AM CDT Mon May 25 2020 && .SHORT TERM...(Today through Tuesday) Issued at 430 AM CDT Mon May 25 2020 By this morning, a remnant MCV will lift northeast into the area with the potential for another Monday night. Showers will accompany the MCV, moving across eastern Minnesota and west- central Wisconsin leaving behind another day of overcast skies. Temperatures will rebound into the upper 70s/low 80s despite the cloud cover. CAMs try to develop another round of showers and thunderstorms from a potential MCV Monday evening. Forecast soundings show MLCAPE values between 500 to 1000J/kg with poor lapse rates and weak vertical wind shear, limiting the severe threat. However, if storms develop there will still be the potential for gusty winds and small hail. Monday evening convection will be dependent on the convective trends across the southern Plains. The final system from the southern Plains trough will lift north across the region Tuesday. After this time, the trough will cut off over Texas and end the train MCVs. For Tuesday, expect high temperatures in the upper 70s with mostly cloudy conditions. Tuesday afternoon/evening presents another chance of showers and thunderstorms. Potential thunderstorm development will be favored across eastern Minnesota and western Wisconsin ahead of the surface front where atmospheric instability will be the greatest. .LONG TERM...(Tuesday night through Sunday) Issued at 430 AM CDT Mon May 25 2020 Zonal flow north of the cutoff system midweek will give way to troughing across the north central and northeastern U.S. late week and next weekend. A brief shot of cooler and drier air will accompany the trough and surface high pressure on Friday. The airmass behind the trough will be relatively dry, keeping the rain chances out of the area for the rest of the forecast period. High temperatures will remain in the low/mid 70s into next weekend. Expect the cool down to be brief as both EPS/GEFS ensembles continue to build the ridge back northeast from the Rockies late weekend and the following week as the trough lifts away. Looking ahead into the first week of June, the CPC outlooks favor above normal temperature probabilities. && .AVIATION...(For the 12Z TAFS through 12Z Tuesday morning) Issued at 701 AM CDT Mon May 25 2020 Generally VFR conditions today and tonight, but we'll see a few scattered showers and thunderstorms over the next 24 hours, along with early morning patchy fog today and again on Tuesday. Winds will be light and variable. Although there is a chance for thunder, confidence was too low to include mention in the TAF. KMSP... Generally VFR conditions today and tonight, but we'll see a few scattered showers and thunderstorms over the next 24 hours, along with early morning patchy fog today and again on Tuesday. Winds will be light and variable. Although there is a chance for thunder, confidence was too low to include mention in the TAF. /OUTLOOK FOR KMSP/ Tue...VFR/MVFR with -TSRA possible.
