.DISCUSSION...
Issued at 222 AM CDT Wed Jul 16 2025

Thunderstorms have been gradually waning in intensity & rainfall
rates overnight, diminishing the threat for any severe weather
or localized flooding. We will see scattered showers and
thunderstorms continue through the day as a surface low passes
through the area, with more widespread coverage along the low`s
track across southern Minnesota. Rainfall amounts will be
lighter today compared to yesterday with additional amounts
generally around 0.25-0.5", except across southeast Minnesota
where some enhanced thunderstorm activity this afternoon will
result in some 1-2" amounts. Temperatures will be a taste of
fall this afternoon with widespread cloud cover & periodic
precipitation keeping temperatures in the low to mid 60s this
afternoon across much of the area. Again, the exception is
across southeast Minnesota & western Wisconsin where warmest
temperatures in the 60s are expected.

Pleasant  summer days are expected Thursday & Friday as cool
canadian high pressure slides over the region. Highs will be in
the low to mid 70s along with drier dewpoints, & extended-range
smoke models do not indicate any dense concentrations of
canadian wildfire smoke. Showers and thunderstorms look likely
Friday night into Saturday morning as a weak shortwave passes
over the area, but widespread strong thunderstorms or heavy rain
looks unlikely. Another region of high pressure then keeps the
weekend dry into Monday, with seasonably cool temperatures in
the upper 70s to low 80s.

Ensemble guidance continues to depict an anomalously strong
ridge developing across the central plains & mid-missisiipi
valley midweek through next weekend. We will likely miss out on
the excessive heat & humidity under the ridge, but can still
expect a return to above-normal temperatures & more humid
conditions. Our placement on the northern periphery of the ridge
places Minnesota & Wisconsin under a classic "Ring of Fire"
pattern where a few shortwaves & organized thunderstorm
complexes will will track along the periphery of the ridge.
Models are notoriously poor at resolving these subtle features
more than a day or two out, but a few chances for severe
weather & heavy rain look likely somewhere across the Upper
Midwest to end the week.

.AVIATION /06Z TAFS THROUGH 06Z THURSDAY/...
Issued at 1124 PM CDT Tue Jul 15 2025

RA/TSRA will slowly but surely fill in across central-southern
MN through western WI through sunrise. TAF sites will experience
intermittent bouts of precipitation followed by more steady
rainfall close to sunrise, lasting for at least half of
Wednesday. Conditions will drop to MVFR, mainly due to ceilings,
and likely IFR, again mainly due to ceilings. However, TSRA with
heavier rainfall may also drop visibility to IFR at times.
Precipitation finally looks to wane Wednesday afternoon with VFR
conditions likely by or during Wednesday evening.

KMSP...VFR to start, but conditions will quickly drop to MVFR as
individual convective cells move across MSP through the early
morning hours. Closer to daybreak, the larger swath of rainfall
over western MN will make its way east to encompass much of
eastern MN, thus allowing for steady rain with a few embedded
thunderstorms for the morning push. Rainfall will continue
through mid-afternoon before diminishing going into the
afternoon push, with dry conditions Wednesday evening.

/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.
