Moderate Risk of Severe Weather Tomorrow


Probability of severe weather 
A moderate risk of severe weather has been issued for Wisconsin. As of now, it appears that the main cause of severe weather is to be wind damage, with this quote from the SPC's outlook:


...SYNOPSIS...
A POWERFUL UPPER TROUGH WILL MOVE EWD OUT OF THE PLAINS AND INTO THE
MS VALLEY DURING THE DAY...WITH A 100+ KT MID LEVEL JET STREAK
EXTENDING FROM ROUGHLY ERN KS INTO SRN WI BY 00Z. AT THE SURFACE...A
DEEP AREA OF LOW PRESSURE WILL MOVE FROM SD/NEB INTO SRN MN...WITH A
COLD FRONT TRAILING ALONG THE MN/WI BORDER EXTENDING SWD ACROSS ERN
IA AND INTO ERN TX. AHEAD OF THE FRONT...STRONG SLY FLOW WILL RESULT
IN AMPLE MOISTURE AND INSTABILITY FOR THUNDERSTORMS...WITH BOUNDARY
LAYER DEWPOINTS NEAR 60 AS FAR N AS NRN WI. THE PROGRESSIVE NATURE
OF THIS TROUGH AND INTENSE WIND FIELDS SUGGEST SIGNIFICANT WIND
DAMAGE POTENTIAL
...AS WELL AS A FEW TORNADOES OVER THE UPPER MS
VALLEY.
FARTHER S ALONG THE COLD FRONT...CONDITIONS WILL ALSO BE FAVORABLE
FOR EPISODES OF DAMAGING WINDS WITH A LINES OF STORMS ALONG THE
FRONT...MAINLY FROM TX INTO AR.


This will be the same piece of energy currently making for a potentially deadly tornado outbreak today, so this should be closely watched.
