I'll say you're gonna get wet, then it's gonna windy, then get cold. What a line on storms, the flashes lighting up the sky!

Right now, it's 75 degrees with a dewpoint of at least 70 south of the twin cities.

WHILE WARM SECTOR BOUNDARY LAYER WILL BE VERY MOIST...WITH DEW
POINTS NEAR 70F...PROSPECTS FOR SIGNIFICANT DESTABILIZATION AND
POTENTIAL FOR VIGOROUS CONVECTIVE DEVELOPMENT ARE UNCERTAIN.

STRONGER SOUTHWESTERLY MID/UPPER FLOW AHEAD OF SHORT WAVE TROUGH
AXIS...FORCING FOR UPWARD VERTICAL MOTION...AND MID-LEVEL COLD POOL
ARE PROGGED TO SIGNIFICANTLY LAG TO WEST OF SURFACE FRONT THROUGH
MUCH OF THE FORECAST PERIOD.
MODELS SUGGEST THERE COULD BE A NARROW
WINDOW OF OPPORTUNITY DURING THE LATE AFTERNOON HOURS FOR
JUXTAPOSITION OF STRONGER LIFT/SHEAR IMMEDIATELY ALONG FRONT...FROM
PARTS OF EASTERN IOWA/NORTHWEST ILLINOIS THROUGH CENTRAL WISCONSIN.
IF THIS OCCURS...DAMAGING WINDS AND SOME HAIL WILL BE POSSIBLE IN
NARROW LINE OF CONVECTION. HOWEVER...TENDENCY SHOULD BE FOR COLD
FRONT TO FAIRLY RAPIDLY UNDERCUT STRONGER CONVECTION...AND SEVERE
THREAT DOES NOT SEEM LIKELY TO PERSIST BEYOND EARLY EVENING.


I would say probably not based on this paragraph.
