.DISCUSSION...
Issued at 319 PM CDT Tue Jul 15 2025

A stalled frontal boundary is draped across central Minnesota early
this afternoon. This has been the focus for some sub-severe
thunderstorms throughout the morning and this afternoon. Additional
thunderstorm development is expected over the coming hours as
further destabilization continues along and south of the front.
A Severe Thunderstorm Watch has been issued for portions of
central Minnesota and western Wisconsin through this evening.
Dew points are in the low to mid 70s with temperatures in the
upper 80s, allowing for heat indices in the mid to upper 90s.
While there is no shortage of CAPE, the shear environment is
marginal. This should lead to some fairly unorganized convection
with the threat for a few strong to severe storms along with
some heavy rain due to slow storm motion. The front will slowly
begin to sag southward late this evening through the overnight,
with most CAMs showing a line of storms on the leading edge. The
front will also work to bring some smoke back to the surface
across far west central Minnesota, though this should be short
lived. As instability decreases after dark, the focus shifts to
more of a heavy rain threat with PWATs approaching 2". An MCV is
forecast to move across northern Iowa early tomorrow morning,
leading to another uptick in storms across much of
central/southern Minnesota and eventually western Wisconsin.
Generally, QPF totals through tomorrow range from an inch to an
inch and a half, but locally higher amounts of 2-3" aren`t out
of the question. Temperatures tomorrow will be some 20-30
degrees cooler behind the front with locales across central
Minnesota topping out in the low 60s with mid 70s further south.
Rain will gradually taper off by late tomorrow.

Thursday and Friday will feature drier conditions and highs in the
low to mid 70s. Our next chance of precip is late Friday into early
Saturday as a shortwave moves across the region. Highs in the 80s
return for the weekend with mostly dry weather expected. A more
active pattern is on the horizon with several disturbances tracking
across the Upper Midwest with temperatures increasing through the
week.

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 643 PM CDT Tue Jul 15 2025

A line of sub-severe storms continues to move through east-
central Minnesota and western Wisconsin early this evening.
Brief periods of heavy rain leading to lower vis and gusty winds
up to 35 knots have been the trend along the line recently.
Behind the line, areas will see a lull in the action before
another round of more persistent SHRA with pulse-y TSRA. On and
off storm chances will last through tomorrow morning, ending
from west to east. MVFR/IFR cigs are likely overnight into
tomorrow for most terminals. Winds stay out of the N/NE,
becoming gusty tomorrow afternoon.

KMSP...Our initial round of TSRA came about an hour early, and
should clear out of the area by 02z if not sooner. Scattered
storms will be possible starting around 05z and lasting through
10z. By then, more persistent SHRA will move in from the
southwest with embedded thunder for a few hours during the
morning. Rain chances will quickly diminish by tomorrow
afternoon.

/OUTLOOK FOR KMSP/
THU...VFR. Wind NE 5-10 kts.
FRI...VFR. Chc -TSRA after dark. Wind SE 5-10 kts.
SAT...VFR. Chc -TSRA early morning. Wind SE bcmg N 5-10 kts.
