All of Iowa, Severe Weather

Severe Weather A Threat Again Today

624
The Storm Prediction Center has a slight risk of severe weather once again across most of the state except the far eastern and northeastern counties. All modes of severe weather are possible once again today, with large hail and damaging straight line winds being the main threats along with heavy rains. The tornado threat will be mainly across the southwestern counties down into KS and OK again today. There are several limiting factors that SPC mentioned in the outlook they are,
1. ABUNDANT PRIOR AND ONGOING CONVECTION FROM ERN OK/OZARKS AREA NWD
ACROSS MO VALLEY AND NWWD OVER PORTIONS KS…EARLY IN PERIOD. THIS
ACTIVITY HAS OVERTURNED AIR MASS ACROSS MUCH OF THAT
REGION…LOWERING DEW POINTS. RESULTING MODIFIED BOUNDARY LAYER
WILL ADVECT NWD ACROSS CENTRAL PLAINS…IA…DAKOTAS AND MO VALLEY
REGION WITH FRAGMENTED AND MODULATED MOISTURE FIELD…CHARACTERIZED
BY EMBEDDED RIBBONS AND POCKETS OF LOW-THETAE AIR.
2. LACK OF WELL-DEFINED FOCI FOR INITIATION IN THAT AIR
MASS…ESPECIALLY FROM ABOUT I-70 NWD.
3. HEIGHT RISES ARE EXPECTED BEHIND SHORTWAVE TROUGH THROUGHOUT
AFTERNOON OVER SRN PLAINS…WITH WEAK MID-UPPER LEVEL VERTICAL
MOTIONS.
4. CAPPING WILL INHIBIT TSTM COVERAGE…ESPECIALLY FROM RED RIVER
AREA SWD ACROSS W-CENTRAL/SW TX. ANY TSTM THAT DOES DEVELOP OFF
DRYLINE OVER TX STILL WILL POSE SVR WIND/HAIL RISK BEFORE NOCTURNAL
DISSIPATION.
5. NARROWNESS OF MOST FAVORABLE MOIST SECTOR MAY LIMIT TIME WINDOW
FOR SUPERCELLS. STILL…GIVEN RECOVERY EXPECTED OVER OK AND
PROBABLY SERN KS…VERY LARGE CAPE WILL SUPPORT ENHANCED
TORNADO/HAIL PROBABILITIES FOR NOW WITHIN SLGT-RISK FRAMEWORK.

So as of now there may or may not be severe weather but there will likely be some storms around that will produce some heavy rains that may lead to more flooding across the area or prolong it in areas where flooding is already occurring. Stay tuned for any changes today.
