A FEW MINOR CONCERNS EARLY THIS MORNING. THE FIRST, SATELLITE
IMAGERY WAS SHOWING PATCHES OF LOW CLOUDS/MARINE FOG JUST EAST OF
TWO RIVERS, AND WELL EAST OF MANITOWOC TOWARDS MID LAKE. THE AREA
WAS DRIFTING WESTWARD EARLIER BUT HAS SHOWN LITTLE MOVEMENT OF
LATE. THE SECOND CONCERN IS KDLH RADAR WAS SHOWING SOME RADAR
ECHOES INTO VILAS COUNTY. COULDN'T RULE OUT A FEW SPRINKLES OVER
THE NEXT FEW HOURS ACROSS NORTH-CENTRAL WI.
FOR TODAY AND LABOR DAY, SKIES WILL BE PARTLY CLOUDY WITH HIGHS
AROUND 80 AS THE STRETCH OF ABOVE NORMAL TEMPERATURES CONTINUE.
THE NORMAL HIGH FOR THIS TIME OF YEAR IS IN THE LOWER TO MIDDLE
70S, JUST A FACT THAT THE COOLER DAYS OF FALL ARE AROUND THE
CORNER. ATTENTION THEN TURNS TO APPROACHING COLD FRONT MONDAY
NIGHT. IT APPEAR THE CHANCES OF RAIN WON'T ARRIVE UNTIL ATE LATE
ACROSS NORTH-CENTRAL WI.
THE TUESDAY INTO WEDNESDAY TIME FRAME IS THE PERIOD OF MAIN
CONCERN. FOR MARINE INTEREST, HAZARDOUS CONDITIONS FOR SMALL CRAFT
DEVELOP ON TUESDAY DUE TO THE GUSTY SOUTHERLY WINDS AND BUILDING
WAVES WHICH WILL CONTINUE INTO TUESDAY NIGHT. WINDS WILL VEER TO
THE WEST ON WEDNESDAY, BUT WILL STILL BE GUSTY TO CREATE HAZARDOUS
CONDITIONS FOR SMALL CRAFT. IF YOU ARE HEADING TO LAKE MICHIGAN
BEACHES, THERE WILL BE AN INCREASED RISK OF RIP CURRENTS
TUESDAY INTO WEDNESDAY MORNING.
AS THE COLD FRONT MOVES ACROSS THE REGION TUESDAY AND TUESDAY
NIGHT, THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG AND AHEAD OF
IT. LOOKING AT SOME OF THE CONVECTIVE PARAMETERS, ENOUGH SHEAR AND
INSTABILITY AVAILABLE FOR STRONGER STORMS. THE STORM PREDICTION
CENTER DAY 3 OUTLOOK HAS A PORTION OF OUR AREA, OUR WESTERN
COUNTIES, IN A MARGINAL RISK OF SEVERE THUNDERSTORMS.
THURSDAY AND FRIDAY ARE EXPECTED TO BE DRY WITH THE NEXT CHANCE
OF SHOWERS/STORMS ON FRIDAY NIGHT AND SATURDAY. ABOVE NORMAL
TEMPERATURES TO CONTINUE INTO NEXT WEEKEND.
