Area Forecast Discussion
National Weather Service Des Moines IA
258 PM CDT Sun Aug 8 2021

.DISCUSSION.../Tonight through Sunday/
Issued at 257 PM CDT Sun Aug 8 2021

The primary messaging highlights through the period include...

* Convective trends and severe weather potential tonight
* Several days of heat and humidity this week
* Cooler, drier, and pleasant weather to end the week into the
  weekend

As has been the case recently, near term convective trends will
be the immediate concern. Although a small cluster of unorganized
convection may linger early southeast, the more prevalent focus
will be convection associated with the upper low nicely noted in
radar and satellite imagery over southeast MN. Expect convection
to gradually expand over the next few hours in what looks to be
an uncapped 1000-2000 j/kg environment. With most activity
expected in the core of the low and just ahead, the better deep
shear to the west and north will likely be unrealized for the most
part keeping any severe weather threat thermodynamically
dominate. However Hires/convection allowing models (CAMs) continue
to suggest additional development on the western flank later this
evening which may tap the better shear and lead to isolated
organization and supercells with several CAMs, including the 18z
HRRR, still noting isolated updraft helicity tracks into the
evening. With 100-150 j/kg 3km Capes near the core of the low,
funnel clouds, and potentially a brief landspout would be possible
even outside a more favorable shear environment. The CAMs seem a
little slow, but overall have a good handle on this evolution and
similar expectations moving a convective cluster slowly across
northern IA this evening, eventually reaching the Waterloo area
toward midnight with the severe weather potential diminishing by
that time.

By tomorrow, the start of heat and humidity concerns begin with
upper level ridging pushing into the Upper MS Valley. While it
will be quite unstable with MLCAPEs 4000+ j/kg central and south,
inhibition and a lack of trigger should keep the forecast dry with
elevated heat indices the primary concern. Peak apparent
temperatures should reach 100-105 south during the afternoon, so
have issued a Heat Advisory during the afternoon and early evening
for the bottom three tiers of counties. The forecast will likely
stay dry into the evening as well, but there are some concerns
overnight. While much of the guidance and the latest NBM are dry,
the Nam and especially the NamNest suggest Monday evening
convection across northern IL may gradually back-build into
eastern and possibly central IA as the low level jet and
associated 0-2km moisture convergence axis gradually lifts back to
the north, so have slight chances to cover that possibility early
Tue morning.

Tuesday will be another warm and humid today, but the remnants of
the current deep PV anomaly over WA will have lifted across the
Canadian provinces with its associated weakening forcing and
frontal boundary pushing through IA. Convection is expected to
develop along the boundary into and after peak heating, and also
possibly persist overnight as warm/moist advection persist aloft
of what's left of the boundary. Deep shear is somewhat limited,
but there will be a window for strong to severe storms due to
moderate to high instability during peak heating. Seasonal
absolute moisture and warm cloud depths may also promote locally
heavy rains fed by a 40kt low level jet.

Wednesday will be warm and humid again, and likely dry with
plenty of inhibition, but a maturing Canadian long wave trough
will eventually push a final front through Thursday ending this
stretch of heat and humidity. With little larger scale forcing or
low level focus, the forecast for the end of the week through the
weekend is mainly dry with seasonal temperatures and lower
humidities.

.AVIATION.../For the 18Z TAFS through 18Z Monday afternoon/
Issued at 103 PM CDT Sun Aug 8 2021

Small patches of MVFR stratus still linger over northeast IA but
VFR conditions are primarily anticipated into the evening. The
only concern will be small clusters of convection dropping across
the northeast third of IA this evening, and southeast this
afternoon and early evening. A window of VFR VCTS has been
included for these areas with a mention of MVFR or less omitted
until confidence increases for any particular location. After the
precip ends overnight, there may also be a period of at least MVFR
fog north until VFR returns later Monday morning.
