Tonight
A shortwave trough will round the southern periphery of a broad northern longwave trough located over western Ontario and Manitoba tonight. As a 30-knot 850 mb jet moves into the region from the Central Plains, showers and storms will develop along and north of Interstate 90. This activity will then move off into northeast Wisconsin and Upper Michigan as this jet veers overnight. Somewhat concerned that we are holding on to the rain chances too long overnight and on Saturday morning in central and north- central Wisconsin. While there is strong 0-3 km and 0-6 km CAPES, the 0-1 mixed-layer CAPES are less than 100 J/kg. As a result, not anticipating any organized severe storms. Low temperatures will range from the mid-50s to lower 60s.
Saturday and Saturday night
A stronger shortwave trough will move through the region on Saturday and Saturday night. As this occurs, it will cause the 500 mb longwave trough to dig southward into the Mid Mississippi River Valley. As this occurs, a surface cold front will move southward through the Upper Mississippi River valley on Saturday and Saturday evening and through the Mid Mississippi River Valley late Saturday night. With the 0-1 km mixed-layer CAPES ranging from 500-1000 J/kg along and 0-3 km and 0-6 km shear greater than 40 knots along and south of the Interstate 90 corridor on Saturday afternoon and early evening, there could be some stronger storms. The main hazards would be damaging wind gusts and hail up to 1 inch in diameter. High temperatures will range from the lower 70s to lower 80s. Low temperatures will range from the mid-40s to mid-50s.
Sunday through Monday
With the polar jet being south of the region and surface high pressure over the region, it will be dry and unseasonably cool across the region for both Sunday and Monday. The largest temperature anomalies (around 10F) will be on Sunday when high temperatures will range from the mid-60s to lower 70s. Low temperatures on Sunday night will range from the mid-40s to lower 50s. On Monday, high temperatures will range from the upper 60s to mid-70s.
Monday night through Friday
With an active polar jet located across the region, there will be periodic showers and storms. Temperatures will remain unseasonably cool with high temperatures will be in the lower and mid-70s and low temperatures will range from the upper 40s to mid 50s.
AVIATION /00Z TAFS THROUGH 00Z SUNDAY/
Issued at 625 PM CDT Fri Jun 12 2026
Primary concerns for aviation interests over the next 24 hours will come from 2 rounds of showers and thunderstorms. The first will roll eastward between 00z and 12z Saturday and mainly remain north of a TOB to ISW line but may (30%) affect RST/LSE.
After 18z Saturday, another round will mainly affect areas along and south of an MCW to 82C line but uncertainty about northern extent was too high to include in RST/LSE TAF. Otherwise, winds mainly out of the west will prevail and VFR is expected outside of TSRA.
