NWS La Crosse, WI wrote its last area forecast discussion before the first event at Oct 31, 10:45 PM CST, 1 hour 15 minutes earlier.
Area Forecast Discussion National Weather Service La Crosse WI 1145 PM CDT Sun Oct 31 2021 .SHORT TERM...(This evening through Monday) Issued at 248 PM CDT Sun Oct 31 2021 This afternoon's clouds gradually dissipate after sunset. Radiational cooling will follow overnight allowing temperatures to drop into the mid 20s to lower 30s. The pressure gradient continues to slowly weaken as the cold front that passed through the area this morning advances eastward, but it will remain breezy tomorrow with 10-15 knot winds and gusts up to 20 knots. Otherwise look forward to partly to mostly sunny skies across most of the area with high pressure building in at the surface to start the week. .LONG TERM...(Monday night through Sunday) Issued at 248 PM CDT Sun Oct 31 2021 The forecast continues to remain consistent- troughing at upper levels has moved in and will continue to dominate the synoptic flow with high pressure at the surface. Model inconsistencies exists with the timing of embedded shortwave troughs in the flow beginning Tuesday, but the GEFS and EC ensemble members largely do not precipitate through the forecast period so there is no mention of sensible weather at this time. Cooler air being funneled in by the northwesterly flow aloft will keep temperatures below normal through the week before rebounding to near-normal values next weekend when a ridge moves in from the High Plains. The coolest days looks to be Tuesday and Wednesday when high temperatures top out in the upper 30s to mid 40s. && .AVIATION...(For the 06Z TAFS through 06Z Monday night) Issued at 1143 PM CDT Sun Oct 31 2021 VFR conditions persist at both sites for the 06Z forecast period. Similar conditions to yesterday with winds and fl050-070 cumulus deck increasing with daytime heating. Expect both to wane with loss of daytime heating (i.e. early evening). Max afternoon wind gusts expected to be lighter than yesterday at ~20-25 kts. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...None. MN...None.
