Area Forecast Discussion National Weather Service La Crosse WI 324 PM CDT Tue Apr 23 2019 .SHORT TERM...(This evening through Wednesday) Issued at 324 PM CDT Tue Apr 23 2019 Quiet weather expected in the short-term. Flooding continues along the Mississippi River and the lower reaches of the Wisconsin River. High pressure builds into the region tonight providing dry and quiet weather. The only forecast concern is on low temperatures over central Wisconsin, where clear skies and calm winds could result in low temperatures falling a few degrees below forecast values. .LONG TERM...(Wednesday night through Tuesday) Issued at 324 PM CDT Tue Apr 23 2019 Main forecast concerns in the long term are on potential fire weather concerns Thursday afternoon and again on Friday due to low afternoon relative humidity and breezy conditions. Focus then turns to a cooler weekend with chances for rain and potentially a rain/snow mix in northern areas. A weak cold front approaches the region from the northwest Wednesday resulting in warmer southwest flow across the area. Wednesday will likely be the warmest day of the week with highs in the upper 60s to lower 70s. The front slides through Wednesday night into Thursday morning, and there could be a few showers along the front, but widespread measurable precipitation is not looking likely. Much drier air moves into the region in the wake of the front along with breezy conditions. Afternoon relative humidity values are expected to fall into the mid to lower 20s. Even drier and windier conditions are in store for Friday with afternoon relative humidity values expected to fall into the lower 20s and we could even see some values in the teens. Have lowered dew point values for both Thursday and Friday afternoon. Rain is looking likely on Saturday as low pressure pushes through the region. Saturday will be a very cool day with highs only making it into the 40s. High pressure makes a very brief return late Saturday night into Sunday morning then rain chances return. Cannot rule out some snow mixing in with the rain Friday night, Saturday night, and possibly late Sunday night, but confidence is low that temperatures would be cold enough for snow. Cool temperatures look to continue into next week with continued chances for rain. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1230 PM CDT Tue Apr 23 2019 VFR conditions will prevail through the period with skies remaining skc largely through daybreak Wednesday. Northerly winds this afternoon will become light and variable tonight as surface high pressure drifts overhead. Winds shift to the SSW Wednesday morning, becoming a tad gusty by midday with increasing mid-level clouds. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...None. MN...None.
