Summary of Windy Conditions May 24, 2012

PERSISTENTLY STRONG SOUTH WINDS OF 25 TO 35 MPH WITH GUSTS UP TO AROUND 50 MPH AFFECTED ALL OF SOUTH-CENTRAL AND SOUTHEAST WISCONSIN TODAY.

IMPACTS INCLUDED...
---A FEW TREES KNOCKED OVER...BUT MANY REPORTS OF BROKEN TREE BRANCHES UP TO 6 TO 10 INCHES IN DIAMETER
---SCATTERED POWER OUTAGES
---REDUCED VISIBILITIES BRIEFLY DOWN TO 1/4 MILE OR LESS DUE TO BLOWING DUST AND DIRT. DRY FARM FIELDS AND A LACK OF SUFFICIENT CROP COVER ALLOWED THE WINDS TO PICK UP DUST AND DIRT.
---DUST DEVIL OBSERVED BY A TRAINED SEVERE WEATHER SPOTTER SOUTH OF STH 106/CI IN SOUTH-CENTRAL JEFFERSON COUNTY.

THE GUSTY WINDS RESULTED FROM A LARGE SURFACE PRESSURE GRADIENT BETWEEN AN DEEP LOW PRESSURE MOVING FROM MINNESOTA INTO NORTHERN WISCONSIN AND A LARGE HIGH PRESSURE EAST OF THE NEW ENGLAND STATES.

BELOW IS A SURFACE WEATHER MAP SHOWING THE LOCATION OF THE LOW PRESSURE AT 6 PM.  NOTE THE SOUTH WINDS AHEAD OF THE ASSOCIATED COLD FRONT.  CLICK ON MAP FOR LARGER VERSION.
