.DISCUSSION...
Issued at 230 PM CDT Sat Jul 6 2024

Current satellite imagery depicts a typical summer afternoon with
plenty of cumulus clouds scattered across the region. As we continue
to heat through the afternoon, the atmosphere will mix and isolated
to scattered showers and storms will result. Some scattered showers
are already present in southwestern Minnesota, but remain pulse-like
due to a lack of deep layer shear. CAMs are showing a similar story,
with scattered pop-up showers and storms through the early evening,
particularly for western Minnesota. As a result of the pulse-like
nature and lack of shear, severe storms are not expected with
today`s activity. However, a few higher performing cells could
produce small hail and/or up to an inch of rain. In all
likelihood, most will get less than a quarter of an inch. After
sundown, storms will transition to more shower-y in nature as a
shortwave disturbance moves overhead. This could result in an
additional few tenths of liquid, but nothing too impactful.

Sunday will be similar to today, with isolated pop-up showers and
storms possible in the afternoon. The biggest difference between
today and tomorrow is location, with tomorrow`s rain chances
favoring western Wisconsin. Temperatures will remain fairly steady
through the early week, with highs around 80. Winds will also be
steady from the west/northwest and light in magnitude. Diurnally
driven showers remain possible Tuesday and Wednesday in western
Wisconsin. Overall, a rather benign weather pattern will couple up
with the light winds and seasonable temperatures giving way to a
pleasant week weather-wise.

The thermometer will trend upwards by late week as winds go
southerly and the atmosphere heats up. Upper 80s and potentially low
90s are possible by the weekend. This aligns well with our
climatologically warmest period of the year, with the high end of
the normal temperature range reaching 84 degrees (for MSP) July 8th
through 23rd. While climatological normal high temperatures will
begin to go down on July 24th, the Climate Prediction Center
forecast is favoring above normal temperatures July 12th through
August 2nd. Ensembles support this trend for the end of the
month, with the GEFS, ECMWF, and CMC all having consecutive
days in the 90s beginning mid-July.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 622 PM CDT Sat Jul 6 2024

A region of scattered thunderstorms will slowly track to the
east this evening. It is currently near the AXN area and will
track east to RWF, STC, MSP, and MKT. Should start falling apart
more by the time it gets to WI with rain more likely than TS at
RNH and EAU. Winds will remain light until thunderstorms
arrive. Should become quieter at night and in the following morning.
Another round of thunderstorms is expected on Sunday afternoon.
The exact location is uncertain and will have to wait for
future TAFs for more details on the exact timing an location of
these storms.

KMSP...Pushed back the start time of the thunderstorms slightly,
but upgraded to a TEMPO from PROB30 as it is looking more likely
that it will happen. Still not certain enough of the line
holding together for prevailing. Will assess the thunderstorm
chances more for the next AMD.

/OUTLOOK FOR KMSP/
MON...VFR. Chc aftn SHRA/TSRA. Wind W 5-10 kts.
TUE...VFR. Chc aftn SHRA/TSRA. Wind NW 5-10 kts.
WED...VFR. Chc aftn SHRA/TSRA. Wind NE 5-10 kts.
