.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
liklihood, 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 /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1211 PM CDT Sat Jul 6 2024

Pop-up thunderstorms have begun to develop across western to
central MN early this afternoon. This activity should be short-
lived but could pass by RWF, AXN, and STC. The more likely
timing for more widespread thunderstorms will be late this
afternoon in western MN as a mid-level disturbance arrives from
the west. These scattered storms will travel west to east across
MN this evening, likely weakening to just rain around 06Z, and
reaching WI early Sunday morning. Have included TEMPOs at MN
terminals for possibility of MVFR during thunderstorms. Outside
of the storms, VFR is likely with cigs dropping to low end VFR
at RNH and EAU towards the end of the period. However, patchy
fog does look possible at AXN near sunrise Sunday. South-
southwesterly winds will slow overnight (with a more southerly
component) before returning again Sunday morning.

KMSP...Kept PROB30 for isolated -TSRA from 22-02Z today. Rain
showers look possible from midnight to sunrise as a disturbance
passes through but conditions should remain VFR. Chance of
afternoon -TSRA again Sunday.
