SHORT TERM CONCERN IS PRECIPITATION CHANCE TODAY AND TONIGHT.

CURRENT SURFACE ANALYSIS INDICATES RAIN SHOWERS NORTH OF THE IRON
RANGE AND IN THE ARROWHEAD. THESE SHOWERS ARE ASSOCIATED WITH A WEAK
SHORTWAVE MOVING THROUGH THE AREA.  THEY WILL CONTINUE MOVE
SOUTHEAST AND SLOWLY DISSIPATE EARLY THIS MORNING. THERE IS AN
AREA OF THUNDERSTORMS ALONG THE ND/SD/WRN MN BORDER MOVING ESE.
THE AREA HAS DECREASED IN INTENSITY OVER THE PAST HOUR. THE
NORTHERN EDGE OF THE PRECIPITATION MAY CLIP CASS AND CROW WING
COUNTIES THIS MORNING. A WEAK SURFACE TROUGH WILL MOVE THROUGH MN
TODAY AND NW WI TONIGHT. IT WILL BRING ANOTHER ROUND OF SHOWERS
AND THUNDERSTORMS. THERE WILL BE SOME INCREASED INSTABILITY WITH
THE TROUGH THIS AFTERNOON AND EVENING. MUCAPES ARE
1500-2000...SHEAR IS 20-40...AND SOME SUN TODAY. SPC HAS THE
FORECAST AREA IN A 5% PROBABILITY FOR WIND/HAIL WITH THE MARGINAL
INSTABILITY.

AN AREA OF WEAK HIGH PRESSURE WILL BUILD INTO THE REGION FROM THE
WEST LATE THIS EVENING. THIS WILL END THE THREAT FOR PRECIPITATION
FOR LATE FRIDAY NIGHT AND SATURDAY. HOWEVER..BY THE AFTERNOON...AN
AREA OF LOW PRESSURE ALONG WITH A UPPER TROUGH WILL MOVE INTO
WESTERN MINNESOTA AND WILL EFFECT THE REGION SATURDAY NIGHT.

THE MODELS ARE IN PRETTY GOOD AGREEMENT THROUGH MUCH OF THE

SOUTHERN WISCONSIN BY SUNDAY EVENING. A SURFACE LOW/TROUGH AXIS
WILL BE ASSOCIATED WITH THIS UPPER WAVE. SHOWERS AND A FEW
THUNDERSTORMS WILL INCREASE IN COVERAGE SATURDAY NIGHT INTO SUNDAY
MORNING...THEN DECREASE FROM NORTH TO SOUTH SUNDAY
AFTERNOON/EVENING. SUNDAY NIGHT SHOULD BE DRY. WE HAVE THE HIGHEST
POPS OVER THE EASTERN PORTION OF THE NORTHLAND LATE SATURDAY NIGHT
INTO SUNDAY MORNING.

HIGH PRESSURE WILL THEN LEAD TO MAINLY DRY CONDITIONS SUNDAY NIGHT
INTO MONDAY NIGHT. THERE MAY BE A FEW SHOWERS TUESDAY INTO WEDNESDAY
OVER THE EASTERN HALF OF THE NORTHLAND WITH A SERIES OF SHORTWAVES
MOVING THROUGH IN THE NORTHERLY FLOW ALOFT. WE ALSO HAVE A SMALL
