Persistent below normal precipitation since February 2021 allowed severe drought conditions to develop across parts of western Wisconsin in the middle of June, including Vernon and Crawford Counties. Rainfall amounts of 1 to 3 inches during the last part of June allowed soil moisture conditions to improve and brought an end to the severe drought.

NWS La Crosse, WI wrote its last area forecast discussion before the first event at Jun 15, 4:42 AM CST, 1 hour 18 minutes earlier.
Area Forecast Discussion National Weather Service La Crosse WI 542 AM CDT Tue Jun 15 2021 .SHORT TERM...(Today through Wednesday) Issued at 227 AM CDT Tue Jun 15 2021 Continued dry for the next couple days as surface high pressure remains sprawled out across Ontario/Great Lakes/Upper Mississippi River regions. Plan on mostly sunny conditions today and Wednesday with highs in the mid-70s to mid 80s and dewpoints in the 40s to lower 50s. .LONG TERM...(Wednesday night through Tuesday) Issued at 227 AM CDT Tue Jun 15 2021 A fairly vigorous mid-level trough rolls into the Northern Plains Wednesday night and our area Thursday into Thursday night. A push of moisture transport and warm air advection ahead of this wave will produce a good chance of showers and storms after midnight Wednesday night. The mid-level trough will then push a surface cold front through Thursday afternoon/evening with another expected round of showers and storms per latest model runs. Models agree on some sort of MCS activity but differ on where it sets up/moves. Just not certain at this point to go more than chancy pops for now. May also have to watch for a few stronger storms as well with 0-3km bulks shear increasing into the 25-35kt range by Thursday evening. High temperatures may be a bit tricky as model soundings hint at a pretty good amount of mid-cloud Thursday to prevent highs from climbing higher than 80s/lower 90s. Hopefully we can get some much-needed beneficial rainfall out of this. Extended models showing a quasi-northwest flow over the CONUS/Upper Mississippi River Valley region through the remainder of the period. This looks to provide an overall cooler period with on/off chances of showers and storms. && .AVIATION...(For the 12Z TAFS through 12Z Wednesday morning) Issued at 540 AM CDT Tue Jun 15 2021 VFR conditions continue with surface high pressure over the region. RAP forecast soundings continue to show plenty of dry air in the low levels, with just enough moisture to produce few to perhaps sct diurnal cumulus today. Winds will be out of the northeast around 10 knots or less today, becoming light out of the southeast early Wednesday morning. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...None. MN...None.
