Area forecast discussion, Jul 24, 3:15 AM CDT, 6 hours before
Area Forecast Discussion National Weather Service La Crosse WI 315 AM CDT SUN JUL 24 2016 .SHORT TERM...(Today and tonight) Issued at 315 AM CDT Sun Jul 24 2016 One more day of uncertainty around the convective potential before we get a respite for a few days. 08z data showing the cold front pushing southeast across MN, running from the Twin Cities down to KFRM. There was some convection along the front, but it was from the Cities northward. Moisture transport and thermodynamic support point to the action staying up there, but some of the mesoscale models were still trying to develop some activity across southeast MN and northeast IA. However, looking at the latest radar trends and model runs, this support is waning. With chances dwindling, have made a change to the forecast with less rain chance this morning. Once the front goes through by midday, that should be it. Cool high pressure begins to build in tonight. .LONG TERM...(Monday through Saturday) Issued at 315 AM CDT Sun Jul 24 2016 High pressure will remain in control Monday into Tuesday, providing a needed break from the rain, heat, and humidity. But a zonal flow regime sets up across the region for the remainder of the week, bringing periodic short waves of varying strength. The first of which comes late Tuesday into Wednesday. Another impacts the region Thursday, with yet another on Friday. There will be some dry periods in there, but it does appear that having rain chances in the forecast every day is the best way to go. Temperatures are looking to be near or below normal through the week. && .AVIATION...(For the 06Z TAFS through 06Z Sunday night) Issued at 1138 PM CDT Sat Jul 23 2016 Pesky stratus issues have once again reared their ugly head the past few hours at RST with an MVFR ceiling developing. Don't see any reason that will go much of anywhere in advance of an approaching cold front slated to arrive just after sunrise. In fact, some of that MVFR stratus will likely sneak eastward toward LSE at times as well. Still watching upstream showers and thunderstorms across west central Minnesota along the incoming cold front. For now, not seeing much development farther south, which will be key to whether or not we see any storms pass near the TAF sites. Per recent trends, unless that development occurs the next few hours, showers and maybe a few storms should scrape by to the north, and will maintain only a vicinity mention at this point. There could be some lingering lower stratus for a time right behind the passing cold front through mid morning, but quick drying midday onward should deliver clearing skies and some stronger northwest winds in the 12 to 16 knot range. && .ARX Watches/Warnings/Advisories... WI...None. MN...None. IA...None. && SHORT TERM...MW LONG TERM...MW AVIATION...Lawrence
