Area forecast discussion, May 28, 2:10 AM CDT, 2 hours 3 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 210 AM CDT THU MAY 28 1998 THUNDERSTORM CHANCES TODAY AND POSSIBILITY OF SEVERE ARE MAIN CONCERNS. LATEST SURFACE ANALYSIS HAS A LOW CENTER LOCATED OVER EASTERN NORTH DAKOTA COLD FRONT EXTENDING SOUTH OUT OF THE LOW INTO EASTERN NEBRASKA. 00Z ETA TAKES THIS FEATURE SLOWLY EAST TODAY AND HAS IT LOCATED FROM NORTHEAST WISCONSIN INTO CENTRAL IOWA THIS AFTERNOON. CURRENT KARX RADAR PICTURES SHOW THUNDERSTORMS MOVING ACROSS EASTERN MINNESOTA INTO WEST WISCONSIN. THESE STORMS LOOK TO HAVE BEEN AIDED BY INTERACTION WITH THE LOW LEVEL JET. THE ATMOPHERE SHOULD BE RATHER UNSTABLE AGAIN THIS AFTERNOON WITH CAPES IN THE 3000-4000 J/KG. MOISTURE ALSO WONT BE A PROBLEM WITH DEWPOINTS AT 850 MB OF 10 DEGREES C. BASCIALLY THE ENTIRE ARX CWFA WILL NEED A MENTION OF THUNDERSTOMS WITH AREAS MAINLY NORTH OF LA CROSSE BEING AFFECTED THIS MORNING...AND PLACES TO THE SOUTH OF LA CROSSE GETTING THE MOST ACTION THIS AFTERNOON. HIGH CAPE VALUES AND LIMITED SHEAR THIS AFTERNOON WOULD SUGGEST THAT THE MAIN THREAT WOULD BE LARGE HAIL. TEMPERATURES TODAY SHOULD BE ABLE TO RISE NICELY AGAIN WITH PLENTY OF SUNSHINE OUTSIDE OF THE MORNING THUNDERSTORMS. HAVE OPTED TO GO CLOSE TO NGM GUIDANCE VALUES AS A STARTING PLACE. THANKS TO GRB AND DMX FOR COORDINATION THIS MORNING. KING
