.SHORT TERM /THROUGH TONIGHT/...
Issued at 139 PM CDT Thu Jun 11 2026
Severe thunderstorm likelihood continues for this afternoon but
some muddiness exists in the forecast details. The imprint on the
atmosphere from the morning MCS is markedly present with stable
low-level air signatures on radar and satellite, and this extends
across much of our area. Offsetting this to some degree is the
1000 mb low pressure near Des Moines tracking northeast, resulting
in some synoptic scale air mass recovery from the south. While
southeast winds are gusting across eastern Iowa now, the amount of
recovery in that is still limited due to lingering widespread
cloud cover. The post MCS air mass is looking more likely to be
enough to prevent a full recovery to northwest portions of the
CWA, at least of a notable tornado threat and significant severe
wind threat. It may even prevent it for many locations north of
I-80 as well, but synoptically there is still strong forcing for
ascent spreading over the area so not able to say that for
certain.
In summary, the area we are particularly concerned for surface-
based supercell/multicells capable of longer-lived mesocyclones
is along and east of the Mississippi River and along and south of
I-80 during the mid to late afternoon. Given more oblique shear
orientation with respect to the incoming cold front, and just how
cold frontal convection tends to evolve, it might not take long
(1-3 hours after initiation) for developing storms across the CWA
to become more clusters or segments, with a good bet of severe
winds in any that do, some significant in any mature bowing
segments (75+ mph).
Storms should be east of the area this evening as a cold front
moves through. This cold front will bring northwest winds in
its wake. Forecast soundings have trended down a bit, but could
still see gusts in excess of 35 mph for a couple of hours after
the front passes through. These winds will taper off overnight
and become more westerly, and temperatures will fall into the
mid 50s.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Issued at 139 PM CDT Thu Jun 11 2026
Friday through Saturday...On Friday, a brief area of high
pressure will build in, leading to mostly sunny skies. This will
exit eastward Friday night, and southerly return flow will
develop. By Saturday afternoon forecast soundings show 1000 to
2000 J/kg, with ample deep layer speed shear. A weak boundary
will be the focus for scattered thunderstorms, and a few could
produce severe weather. Right now large hail looks like the
primary threat.
Sunday through Thursday...Ensemble guidance shows lower height
anomalies spreading across the central US next week, which
supports cooler temperatures. A few weak disturbances embedded
in northwest flow will bring small chances for showers and
thunderstorms, but overall the first half of next week appears
mostly dry.
&&
.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 1235 AM CDT Thu Jun 11 2026
Main concern through 00Z this evening is scattered
thunderstorms. A few storms could produce damaging wind and
hail, but given the lower predictability did remove hail from
the TAFs.
A cold front will follow once storms exit the region this
evening, bringing VFR conditions, and a brief period of gusty
northwest winds. These winds will decrease later this evening
and overnight.
