storms soon firing in Southern Minnesota
As the low gets closer to the Minnesota-South Dakota border storms should begin popping as of right now temps range from 85-90 degrees with dew points of 60 or higher

Absoultely. As I posted on the another topic, the storms are actually going to struggle a bit to form into the upper atmosphere because the shear is so high:

SPC MCD 182033
WIZ000-MNZ000-182230-
MESOSCALE DISCUSSION 0370
NWS STORM PREDICTION CENTER NORMAN OK

AREAS AFFECTED...CNTRL MN
CONCERNING...TORNADO WATCH 83...
VALID 182033Z - 182230Z
...ENVIRONMENT IS FAVORABLE FOR SEVERE TSTMS NEXT FEW HOURS ACROSS
CNTRL MN...
LATEST RADAR FROM MINNEAPOLIS SHOWS STORMS RAPIDLY DEVELOPING ALONG
AND NORTH OF WARM FRONT WHICH EXTENDS FROM BBB/STC/RZN. VERY STRONG
TEMPERATURE GRADIENT NOTED...WITH UPPER 80S/90S ACROSS SWRN MN AND
UPPER 30S/LOWER 40S NORTH. COVERAGE IS EXPECTED TO INCREASE VERY
QUICKLY IN ATMOSPHERE CHARACTERIZED BY SBCAPE VALUES NEAR 2000 J/KG.
SUPERCELLS ARE LIKELY...GIVEN DEEP LAYER SHEAR VALUES AOA 50 KT.
TORNADOES WILL BE POSSIBLE WITH ANY SURFACE BASED STORM THAT HAS
MAXIMIZED SHEAR ALONG THE BOUNDARY. RECENT 0-1KM SRH HELICITY VALUES
ARE NEAR 150 M2/S2 AND ARE CONSIDERABLY LARGER FARTHER EAST. THREAT
INITIALLY MAY BE FROM LARGE HAIL AS STORMS STRUGGLE TO OVERCOME THE
TREMENDOUS SHEAR. HOWEVER...TORNADO THREAT WILL INCREASE AS SFC LOW
APPROACHES.
IN ADDITION TO THE THREAT OF TORNADOES...VERY LARGE HAIL IS LIKELY
WITH STORMS...ESPECIALLY IN ORGANIZED SUPERCELLS. LOCALLY RUN HAIL
MODEL SUGGESTS HAIL GREATER THAN 2" IS POSSIBLE.
