Area forecast discussion, Apr 7, 12:44 AM CDT, 2 hours 22 minutes before
Area Forecast Discussion National Weather Service Twin Cities/Chanhassen MN 1244 AM CDT Tue Apr 7 2020 .UPDATE... Issued at 1234 AM CDT Tue Apr 7 2020 Updated to include 06z aviation discussion below. && .SHORT TERM...(This evening through Tuesday night) Issued at 252 PM CDT Mon Apr 6 2020 Extensive cloud cover that was across the area for most of the day has mixed out some... but cu is filling in the holes and redevelopment of low clouds will occur tonight along with some areas of fog. An area of showers and embedded thunderstorms still looks to work into the western portion of the area later this evening as the instability axis ahead of the cold front works in from the Plains. The best chance for precipitation will be across the northern half of the area, where elevated instability will combine best with isentropic ascent. With MUCAPE values getting near or above 1000 J/Kg and decent deep layer shear there is some potential for a few strong elevated storms. The main threat from any such activity would be large hail, generally north of I-94 during the overnight hours into early Tuesday morning. The front will push east Tuesday, taking precipitation chances with it. .LONG TERM...(Wednesday through Monday) Issued at 252 AM CDT Mon Apr 6 2020 The overall theme for the latter portion of the forecast period hasn't changed, with the model guidance still in good agreement on a change to the large scale pattern that favors much cooler weather for our area. The modest ridging currently in place will give way to northwest upper flow by midweek, then troughing across the eastern half of the continent by the weekend. Much colder air will work into the area behind a cold front on Wednesday, and this will remain through the remainder of the period (albeit with some modification over time). The main chances for precipitation will be on Wednesday, primary along the frontal boundary as it pushes through the southern portion of the forecast area, then again over the weekend (although guidance still has some disagreement on the timing for things, with the GFS lagging the ECMWF and Canadian solutions). Some shower activity in between those systems can't be ruled out given the cold air aloft and opportunity for decent boundary layer heating with April sunshine. && .AVIATION...(For the 06Z TAFS through 06Z Tuesday night) Issued at 1234 AM CDT Tue Apr 7 2020 MVFR ceilings, with some pockets of IFR ceilings, have overspread much of the area and ceilings will continue to drop overnight as a warm front approaches from the west. IFR ceilings are expected at all sites with some MVFR-IFR fog developing through daybreak Tuesday. The main concern is convection through Tuesday morning. Best chances remain along and north of the I-94 corridor but instead of moving ENE, models have aligned with radar trends in the convection moving more due E and potentially SE in eastern MN into western WI. As such, have only kept the 2 southern MN TAFs dry with a mix of SHRA and TSRA in the TAFs. For winds, the trend is to keep SE winds in place ahead of the system then winds quickly snap to SW and NW as the low pres center and its cold front move through the area. Timing is still a little tricky so some leeway of 1-2 hrs may be needed for the wind shift and clearing Tuesday afternoon. KMSP...Have adjusted the precip mention to a TEMPO as convection in western MN is moving generally due E and there is a fair amount of lightning in the convection so although only generic thunderstorms, they may come close enough to MSP for them to show up in the observations. The duration of TSRA may be a bit longer than the current TEMPO shows so that may need to be adjusted based on radar trends. Otherwise, confidence remains high in having IFR conditions during the morning push, especially for ceilings. Clearing will be fairly quick late morning into early afternoon as the cold front pushes across the area. /OUTLOOK FOR KMSP/ Wed...VFR. Chc -TSRA/MVFR. Wind NW 10-15G25kts. Thu...VFR.
