Area Forecast Discussion
National Weather Service Quad Cities IA IL
248 PM CDT Fri Jul 3 2026

.KEY MESSAGES...

-  Extreme Heat Warning continues through this evening for the south,
   the other areas cloud debris and lingering precip should
   keep heat index readings below headline criteria. Still very
   humid and uncomfortable. Not as hot early next week with more
   seasonable temps.

-  Messy storm pattern through the weekend with several rounds
   of storms possible. But many dry hours embedded in with the
   storm chances as well.

&&

.SHORT TERM /THROUGH TONIGHT/...
Issued at 243 PM CDT Fri Jul 3 2026

The outflow boundary from last nights storm complex is now moving
back north and allowing the atmosphere to recover. The heat
headlines will remain in place with the 10 PM expiration time
looking reasonable.

The flood watch has been expanded in areal coverage down to Highway
34 in southeast Iowa and extended through 7 AM Saturday morning.

As the boundary moves back north, it will collide the other
boundaries across the area. Each boundary and the intersection of
boundaries will provide numerous foci for diurnal convection
development any time after 4 PM. Overall coverage will be isolated
to scattered (10-35%) through sunset with said convection slowly
decaying through midnight.

Late this afternoon storms will fire in eastern Nebraska and grow
upscale into another organized storm complex. The storm complex will
then move generally east across Iowa and arrive in eastern Iowa at
after midnight.

Thus rain chances will be low through 4 PM followed by an uptick
through sunset and then perhaps another lull. Depending upon where
the storm complex forms and moves tonight, there should be a general
uptick with rain chances after midnight.

Moisture levels in the atmosphere remain quite high so storms will
have plenty of moisture available to produce rain. Warm rain
processes have a 50-70% probability of coming into play so rainfall
rates in the stronger storms will potentially be high. Corfidi
vectors become perpendicular to each other and at times are opposed
to each other. This raises the potential for storms to repeat over
the same areas or move very slowly. If this occurs then rainfall
would have a high probability of being excessive.

As for the severe risk tonight, the better risk is the western half
of Iowa. Storms should be in a decaying mode when they arrive in
eastern Iowa. An isolated severe storm cannot be ruled out with
damaging winds and hail being the primary risks.

Saturday will likely be similar to Friday morning; a decaying storm
complex entering or over eastern Iowa that has new convection
developing along outflow boundaries. This scenario will likely be
seen through mid-morning followed by convection dissipating in the
late morning. Boundaries left over from the nocturnal convection
will provide numerous foci for diurnal development mid to late
afternoon Saturday. Like Friday, coverage will be low at 10-30
percent. There may be a couple of severe storms Saturday with
damaging wind and hail being the primary risks.

Heat and humidity will continue across the area on Saturday but peak
afternoon heat indices along/south of Highway 30 look to be 95 to
100. North of Highway 30, peak heat indices look to be 90 to 95.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 300 AM CDT Fri Jul 3 2026

Saturday night...there are signs of short wave energy and mid
level jet flux starting to angle the steering flow acrs the
upper Midwest more northwesterly. this process may form
nocturnal thunderstorms right overhead, just off to the
southwest, or north to northeast of the local CWA into Sunday
morning. Several models and ensembles support all three of these
scenarios and makes for high uncertainty at this juncture in
time. Will have to cover these chances with decent POPs and
await further runs for any changes.

Sunday...Not as hot and with a northwest flow upper wave overhead,
there will be the chance for isolated to widely sctrd showers and
storms popping up in the afternoon heating. High CAPE-low shear type
of scenario.

Quick look at next week, appears to be large/broad ridging regime
developing acrs much of the upper mid CONUS, meaning mainly dry and
seasonable for the home team through at least mid week.

&&

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1236 PM CDT Fri Jul 3 2026

Weak forcing and numerous outflow boundaries across eastern Iowa
and northern Illinois means isolated to scattered (10-30%
coverage) of SHRA/TSRA will be possible through sunset. After
02z/04 yet another organized storm complex will develop across
western Iowa and slowly move east through 12z/04. After 12z/04
the storm complex will slowly decay. Given the high moisture
levels in the atmosphere, IFR/LIFR conditions are possible for
any TSRA that impacts a TAF site.

This Hazardous Weather Outlook is for portions of north central
Illinois...northwest Illinois...west central Illinois...east
central Iowa...northeast Iowa...southeast Iowa and northeast
Missouri.

.DAY ONE...THIS AFTERNOON AND TONIGHT

The Extreme Heat Warning will continue through this evening
for areas generally along and south of an Ottumwa, Iowa to
Galesburg, Illinois line. Peak heat indices just over 100 are
expected.

The entire Outlook Area will be susceptible to rounds of
thunderstorms tonight. The potential for strong to severe storms
and flash flooding will also continue through this period. Most of
the area is in Slight Risk(Level 2 out of 5) tonight with
damaging winds the primary concern. Repeated storms producing
heavy rainfall at high rates will also have the capability to
produce flash flooding.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

There is a Marginal Risk(Level 1 out of 5) for severe weather on
Saturday for areas generally south and east of a Mount Pleasant
Iowa, to Quad Cities, to Princeton Illinois line.

Locally heavy rain and flash flooding will also continue to be a
threat on Saturday. The repeated rounds of heavy rain will produce
rises on some area creeks and tributary rivers, with a few
potentially reaching bankfull or even approach the flood stage
through early next week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed at times today through Saturday.
