Funnel Cloud in Iowa, July 1, 2021

Area Forecast Discussion

.UPDATE...
Issued at 352 PM CDT Thu Jul 1 2021

Water vapor imagery shows a shortwave trough moving south across
Minnesota. This system will bring a broken 6-8K deck of clouds to
much of the area this afternoon and evening. Soundings continue to
show weak capping mainly west of the Mississippi River. As a
result, we will continue to see isolated showers in these areas
through mid evening.

.SHORT TERM...(This evening through Friday)
Issued at 231 PM CDT Thu Jul 1 2021

Latest 18z surface analysis shows weak cold front extending from
northwest Minnesota to southern Wisconsin and high pressure over
southern Ontario. With daytime heating diurnal cumulus has developed
across central Wisconsin per the latest visible satellite imagery.

Surface ridge builds over the Upper Peninsula of Michigan and much
of Wisconsin tonight into Friday. Subsidence underneath ridge will
provide mostly clear/mostly sunny skies and slightly cooler
temperatures. High temperatures are expected to be in the upper 70s
to lower/middle 80s. With light winds and clear skies...patchy fog
will develop after 06z in river valleys tonight. The fog is not
expected to be widespread in river valleys...will leave mention
of fog out for now.

.LONG TERM...(Friday night through Thursday)
Issued at 231 PM CDT Thu Jul 1 2021

As the holiday weekend approaches, dry and very warm conditions are
still expected. A mid-level low in the Eastern Great Lakes region
will move east Friday night leading to warm inflow to the region
Saturday and Sunday. Temps will be in the upper 80s to low 90s
Saturday before climbing into the low/mid 90s on Sunday. Moisture
transport over the region picks up Saturday night into Sunday
raising dewpoints to the mid 60s. Heat will be the main hazard to
keep an eye on this weekend.

Monday through Wednesday is our next opportunity for some precip.
Lower amplitude flow with embedded shortwaves sets up across the
Upper Midwest and could lead to periods of convection during this
time. We are also monitoring the possiblity of a frontal passage
from the northwest Monday into Tuesday. Because predictability of
timing and strength of any precip remains low, broad-brushed rain
chances continue to be utilized. For now, warmer temperatures can
continue to be expected through Wednesday with dew points in the
mid/upper 60s.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 626 PM CDT Thu Jul 1 2021

A shortwave trough will move south across Minnesota and Iowa
tonight. This system will provide a broken 6-10K deck of clouds
for KRST and maybe briefly at KLSE through 02.06z. Once this
system moves away from the area, skies will become mostly clear
and the wind speeds will be generally less than 5 knots.
