Areas affected...southeastern Minnesota and portions of eastern Iowa
into western Wisconsin and northwestern Illinois
Concerning...Severe potential...Watch unlikely=20
Valid 031915Z - 032115Z
Probability of Watch Issuance...20 percent
SUMMARY...A few strong/locally severe storms are expected to evolve
with time near the Upper Mississippi River Valley, and spread eastward/northeastward with time. With the stronger storms expected
to remain isolated, and magnitude of risk likely to remain limited,
WW issuance is not currently anticipated.
DISCUSSION...Latest radar loop shows storms developing from near the southeastern Minnesota/Wisconsin border/Mississippi River southward
into northeastern Iowa. The convection is occurring in an area of heating/destabilization that is ongoing west of remnant
precipitation and associated cloud cover across central and eastern
Wisconsin. While continued heating -- which has pushed mixed-layer
CAPE values to around 2000 J/kg -- will likely support additional
storm development, the deep-layer wind field only modestly
increases/veers with height. This suggests mainly multicell
organization of the stronger updrafts, likely limiting overall
severe potential. In addition, with storms tending to shift eastward/northeastward into the more rain- and cloud-cooled airmass
with eastward extent, current expectations are that WW issuance may
not be required.
