.DISCUSSION...
Issued at 308 PM CDT Wed Jul 8 2026

A cold front was located across northwest Wisconsin back into
the Twin Cities metro area early this afternoon with high
pressure building across the Northern Plains and Upper Midwest.
Showers and thunderstorms were developing ahead of the cold
front across northwest Wisconsin along and south of a 
Manitowish Waters to Hayward to Hinckley line. Cloud cover
through the day has limited instability across northwest
Wisconsin and no strong or severe storms are expected before
activity exits the region later this evening. Heavy rainfall
does remain possible across Price County into this evening with
PWATs in excess of 1.7" in place per latest SPC RAP analysis. 

High pressure will then build in for Thursday into Thursday
night with zonal flow aloft. Flow turns more northwesterly on 
Friday with an embedded shortwave moving through the Upper
Midwest Friday afternoon into Friday night. This will bring
chances for shower and a few thunderstorms, mainly along the
International Border and Arrowhead. Heading into the weekend,
upper level ridging will develop across the central CONUS with
southerly/southwesterly flow at the surface around high pressure
in the Mid-Mississippi Valley. This will pump well above normal
temperatures into the region with highs in the 80s Saturday
before low 90s arrive for Sunday and Monday. Increasing 
dewpoints are also expected this weekend which will lead to hot 
and humid conditions with apparent temperatures reaching into 
the lower to mid-90s. These conditions may lead to an increased
risk of heat-related illness and heat headlines may be needed. 

A cold front will push across the Upper Midwest on Tuesday and
will bring low chances for showers and thunderstorms as it moves
through. Cooler air will also arrive in the wake of the front
for Wednesday as highs fall back into the low to mid 80s.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 630 PM CDT Wed Jul 8 2026

VFR conditions at all terminals except periodic drops to MVFR at
HYR. Fog is expected tonight at HYR from earlier rain showers,
dropping to IFR conditions. There's a lesser chance at DLH and 
HIB, but confidence is high enough to include MVFR/IFR
conditions in the TAF. Winds will be light and variable
throughout the TAF period.

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 308 PM CDT Wed Jul 8 2026

Main forecast concern in the near term will be dense fog this
afternoon and tonight. Fog has already developed along the North
Shore per webcams and is expected to develop across the
remainder of the nearshore waters into this evening before
lifting after sunrise Thursday. Winds will remain under 10 
knots through Saturday.

Forecast Discussion at weather.gov/mqt.

.FIRE WEATHER...
Issued at 1247 PM CDT Wed Jul 8 2026

A few showers and thunderstorms will remain possible across
parts of interior northwest Wisconsin this afternoon, mainly
Price County and adjacent areas. Additional rainfall up to
0.10-0.15" will be possible in this area. Dry conditions will
prevail elsewhere. RH values are still forecast to vary widely
across the region, with readings of 30-45% along and north of
the Iron Range into the Arrowhead with values above 50%
elsewhere. Winds will be variable this afternoon at 5 to 10 mph.

A dry and warming pattern is expected to setup for the remainder
of the week and into the weekend outside of very low shower and
thunderstorm chances in far northern areas Friday afternoon into
Friday night. Highs will reach into the 80s Thursday- Saturday 
with 90s in the mix by Sunday. Thursday looks to be the driest 
day in terms of RH with values of 25-35% along and north of the 
Iron Range into the Arrowhead with values of 35 to 45% 
elsewhere. Increasing humidity heading into the weekend will 
keep minimum values at around 35% or above. Winds will remain 
under 15 mph into Saturday with some gusts to around 20 mph by 
Sunday.

breakdown of fire weather conditions.
