.DISCUSSION...
Issued at 116 PM CDT Fri Jun 19 2026

Light rain showers are exiting the area across western Minnesota
while another band of light rain is moving across the I-90
corridor across far-southern Minnesota. However, our area of
interest this afternoon will be with the building cumulus field
across northwest & west-central Minnesota. Instability isn't
going to be great after the rain & clouds this morning, but
very steep mid-level lapse rates mean than surface-based CAPE
of 500-1000 J/kg should develop this afternoon & allow for these
budding showers to build into scattered thunderstorms by mid-
afternoon. Impressive wind shear for mid-June will be in place
over the area as a jetstreak over the Upper Midwest provides
around 60 kts of 0-6km shear across MN & WI. However the weaker
instability means that any thunderstorms probably wont be able
to realize all of this deep shear, so effective shear values
look to be on the order of 30-40 kts across central MN & western
WI where we expect the most widespread storm coverage. This
still plenty of shear for storms to become organized, so we are
expecting a few strong to severe thunderstorms later this
afternoon with large hail the primary threat followed by
sporadic damaging wind gusts. The main window for these severe
thunderstorms looks to be between 3 PM to 7 PM, with the Storm
Prediction Center highlighting an area along the I-94 Corridor
of eastern MN & western WI with a Level 2/5 (Slight Risk) threat
of severe storms. The storms will begin to weaken as we get
closer to sunset, with the thunderstorms threat mostly over with
across western Wisconsin by 8-9 PM.

Weak high pressure moves into the region behind today's system,
setting up a seasonably cool & dry weekend with highs generally
in the low to mid 70s expected. Can't rule out a coupe, isolated
rain showers across western Wisconsin from the cumulus field
Saturday afternoon, but better chances for light rain look to
come Sunday morning across far-southern Minnesota. However, the
main threat for rain looks to set up to our south over Iowa.

Looking into next week: zonal flow aloft should extend the quiet
weekend weather into Monday, but building troughing over the
Great Lakes brings an increased chance for rain Tuesday into
Wednesday. This mainly looks to be another system with
widespread rain showers & a few isolated thunderstorms, & the
threat for any severe weather or heavy rain is low. Northwest
flow persists through the week in response to the troughing
over the Great Lakes & building ridging over the west, which
will keep temperatures seasonably cool through the week. Models
hint at various transient disturbances embedded within the
northwest flow that could lead to low chances for precipitation
later in the week, but mostly quiet weather looks to be the
forecast until next weekend.
