Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
705 AM CDT Thu Jul 2 2026

.KEY MESSAGES...

- Thunderstorms & locally heavy rainfall across far-southern
  Minnesota continue into this morning.

- Another round of thunderstorms is expected tonight & through
  the overnight hours. Damaging wind gusts & locally heavy
  rainfall are possible with these storms.

- Warm & muggy weather continues into next week.

.DISCUSSION...
Issued at 306 AM CDT Thu Jul 2 2026

A stationary front remains stalled out across far-southern
Minnesota overnight, which has allowed for thunderstorms to
constantly regenerate along the boundary. Most of the
thunderstorms activity so far has been across southeast
Minnesota & southwest Wisconsin, but ne development is beginning
to spread northwards out of northern Iowa. These thunderstorms
are slow- moving, meaning locally heavy rainfall is expected
with rainfall rates up to 2" an hour given the rich moisture
over the region. Some areas could see rainfall amounts up to 4"
by the time the thunderstorms begin to wane late this
morning/early this afternoon.

Elsewhere, a dry day is expected with warmer temepratures near
90 degrees as the precipitation & cloud cover mostly remains
southeast of the area. dew points will continue to be muggy, but
not excessively so with heat index values topping out this
afternoon in the mid-90s. CAPE values up to 3000 J/kg will
build by late afternoon/early evening along wit deep shear
values near 30 kts, setting the stage for another round of
potentially severe thunderstorms later tonight.

Thunderstorms are expected to initially develop late this
afternoon across central Dakotas, where they will merge into a
line or multiple clusters of storms & eventually move into
western Minnesota this evening. It's uncertain exactly when &
where this complex of thunderstorms may track is it moves east
through the night, as has been the case with most of the
thunderstorm complexes this week. Damaging wind gusts will be
the primary hazard with these thunderstorms followed by a low
chance of a few spin-up tornadoes. The greatest severe threat
will be across western Minnesota as the thunderstorms are
expected to diminish slightly as we get closer to midnight, but
wherever the thunderstorm complex tracks through the night will
have a threat for gusty winds. Locally heavy rainfall is also
possible, although this threat will be higher across southern
Minnesota, where a separate area of slow-moving thunderstorms is
expected to develop during the overnight hours. Thunderstorms
will be waning after sunrise with dry conditions then expected
through most of Friday. But wait! There's more! Another
thunderstorm complex looks likely to develop across the Dakotas
Friday evening & track eastwards through Minnesota & Wisconsin
during the night. This thunderstorm threat looks to be highest
across southern Minnesota & damaging wind gusts will again be
possible.

Temperatures look to be cooler in the low to mid 80s through
the Holiday Weekend, but the muggy dew points will continue.
pretty typical 4th of July weekend weather around these parts.
There will be some scattered thunderstorms to dodge saturday
evening for any fireworks displays but the chance for any
widespread thunderstorm complex & severe weather does look lower
than previous days. We may even see a few dry days develop
Sunday into early next week as Canadian high pressure moves into
the Upper Midwest. Looking-froward, no end in site to the warm
& muggy conditions with more of the same continuing through next
week.

.AVIATION /12Z TAFS THROUGH 18Z FRIDAY/...
Issued at 650 AM CDT Thu Jul 2 2026

VFR conditions expected through most of the period. Areas of fog
remain in place across central MN terminals with VIS less than 1
mile at RWF, STC, and RNH in western WI. Fog will slowly
dissipate over the next few hours. FEW-SCT250 expected through
the morning with winds light AOB 5 knots and generally S/SW or
VRB in direction. Winds will become 5-10 knots during the late
morning and afternoon timeframe. There still remains a bit of
uncertainty with regards to afternoon and evening SHRA/TSRA
potential across the area. Guidance continues to show a wide
range of outcomes through the period. HREF ensemble reflectivity
> 40dbz paintball output shows a not so confident depiction of
afternoon/evening storms, therefore forecast confidence is low.
Hence no mention of afternoon activity in this TAF issuance.
Updates will be likely at future TAF issuances when high res
guidance depicts activity a little better. PROB30s do exist in
the TAF for all MN terminals late this evening and early
overnight for -TSRA.

KMSP...VFR conditions expected through the morning hours and
through most of the afternoon and evening. Winds light AOB 5
knots and VRB or southerly in direction, winds will become 5-10
knots by late morning and afternoon timeframe. Skies FEW-
SCT250 through the day. FEW at 5-10 kft will be possible during
the afternoon hours as well. Guidance continues to show another
round of evening and overnight showers and storms. PROB30 exist
in the TAF for MSP late this evening and early overnight for
-TSRA.
