Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
208 PM CDT Fri Jun 5 2026

.KEY MESSAGES...

- Scattered thunderstorms, some capable of hail and gusty winds,
  will continue through early evening. Areas of fog developing
  late tonight.

- Drier and warmer Saturday, before another round of showers and
  thunderstorms late Sunday through Monday.

- Hotter and more humid conditions by the middle of next week
  with highs in the 90s expected. Heat indices may exceed 100
  degrees.

.DISCUSSION...
Issued at 208 PM CDT Fri Jun 5 2026

Scattered thunderstorms are beginning to develop across western
MN early this afternoon ahead of the main shortwave trough.
Storms are also developing along an outflow boundary, left
behind from from this morning's activity, from Cambridge
southwestward to Buffalo. Activity will generally increase in
coverage and expand eastward this afternoon, while remaining
fairly disorganized due to a lack of strong deep layer shear.
Nevertheless, some may pulse up and become severe for a short
time, as has been the case for the past couple of days.
Marginally severe hail and gusty winds are the main threats
until storms weaken near sunset. Clouds will clear this evening.
With light winds and recent rain areas of fog are probable
overnight.

Weak high pressure over the Great Lakes will turn winds light
easterly Saturday and drier air will work in. Temperatures will
rebound back to the upper 80s.

An upper low over the southern Plains Saturday will lift north
to the Upper Midwest Sunday night and Monday. With it will come
pwats between 1.75-2 inches. However, poor mid level lapse
rates and little low level forcing may make it difficult to
sustain deep convection which should keep QPF relatively light.

Next week a trough will dig into the west and a ridge will
buckle northward across the eastern U.S. Southwest flow will
overtake the central U.S. and several embedded disturbances may
bring storm chances Tuesday into early Wednesday. 700 mb temps
will climb to near +12C, which is near the warm limit to
allow convection. A hot and humid airmass will advect north,
and if convective development does not occur, widespread low to
mid 90s are expected Wednesday. Heat indices should climb to
around 100. The trough will approach Wednesday and a cold front
may push through as early as Wednesday evening. Showers and
thunderstorms should develop along the front and SPC highlights
the Upper Midwest in their day 6 outlook. Cooler air will
follow the front, and if this timing holds, the forecast may be
way too warm Thursday. Given storm chances and a quicker cold
front arrival, forecast temperatures have trended down mid to
late week.

&&

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 112 PM CDT Fri Jun 5 2026

Scattered thunderstorms will develop this afternoon north of RWF
and MKT. Highest coverage of storms will be after 20-21Z, but
still not confident enough for anything more than a PROB30 for
now, except at RNH early this evening. TS will weaken and
dissipate near sunset with clearing skies late evening. Areas of
fog will develop overnight, with IFR conditions possible.

KMSP...Tough call on the timing of direct impacts, if any at
all, from TS this afternoon and evening. Given the scattered
nature of the expected convection, continued with the PROB30
until storms begin developing and trends can be determined.

/OUTLOOK FOR KMSP/
SAT...VFR. Wind N at 5-10 kts, becoming E.
SUN...Mainly VFR. Chc TSRA/MVFR late. Wind SE at 10-15 kts
MON...SHRA/TSRA likely. MVFR possible. Wind SE 5-10 kts.
