DISCUSSION

THIS AFTERNOON AND TONIGHT:
A STALLED FRONT STRETCHES FROM NEAR THE TWIN CITIES EASTWARD
THROUGH NORTH CENTRAL WI AND ACROSS NORTHERN LAKE MICHIGAN THIS
AFTERNOON. NORTH OF THIS FRONT GUSTY EAST WINDS ARE BLOWING
ACROSS THE NORTHLAND. WITH INCREASED LOW LEVEL MOISTURE AND FLOW
OFF THE LAKE, PATCHY DRIZZLE AND LIGHT RAIN ARE EXPECTED TO
CONTINUE. STARTING TO SEE MORE LIGHT SHOWERS DEVELOP OVER THE
ARROWHEAD, AS LOW LEVEL ISENTROPIC LIFT INCREASES AND A MID
LEVEL JET MOVES OVERHEAD. FURTHER TO OUR WEST, MORE ORGANIZED
SHOWERS AND STORMS ARE ONGOING ACROSS PORTIONS OF ND.
FOR THE REST OF THE AFTERNOON AND EVENING, SHOWERS WILL BECOME
MORE WIDESPREAD AS A SHORTWAVE LIFTS THROUGH THE REGION. CANNOT
RULE OUT A THUNDERSTORM OR TWO, MAINLY FROM BRAINERD EASTWARD
ACROSS NORTHWEST WI. INSTABILITY PARAMETERS ARE MEAGER, WITH
LIMITED MUCAPE ABOVE A CAP BUT IN THE HAIL GROWTH ZONE. IF A
STRONGER STORM DOES DEVELOP, SMALL HAIL WILL BE THE MAIN
CONCERN. ADDITIONAL RAINFALL AMOUNTS WILL BE BETWEEN
0.10-0.50 INCH, AND DEPENDENT ON WHERE MORE PERSISTENT HEAVIER
RAIN FALLS.
TUESDAY AND WEDNESDAY:
UPPER LEVEL FLOW BECOMES MORE ZONAL TUESDAY, WITH SHOWERS
ENDING ACROSS THE ARROWHEAD TUESDAY MORNING. LOW LEVEL MOISTURE
LINGERS ACROSS THE AREA, AND WOULD NOT RULE OUT A FEW LIGHT
SHOWERS AROUND BUT FOR NOW WILL MAINTAIN A DRY FORECAST FOR MID
MORNING AND THROUGH THE DAY. HIGH PRESSURE ARRIVES WEDNESDAY,
KEEPING CONDITIONS DRY WITH CLEARING SKIES. TEMPERATURES WILL BE
MUCH MORE SEASONABLE WITH HIGHS IN THE 50S AND 60S. OVERNIGHT
LOWS WILL FALL BACK INTO THE 30S.
THURSDAY AND FRIDAY:
NOT MANY CHANGES NOTED FOR THE END OF THE WEEK SYSTEM. GUIDANCE
CONTINUES TO BE IN BETTER AGREEMENT WITH ONE LOW EJECTING OUT
OF THE CENTRAL ROCKIES STARTING THURSDAY MORNING, PUSHING
MOISTURE NORTHEASTWARD TOWARD THE UPPER MIDWEST. ANOTHER LOW
WILL BE DROPPING SOUTH OUT OF CENTRAL CANADA AND WILL PICK UP
THE PLAINS LOW SOMEWHERE OVER THE MIDWEST. ALTHOUGH THERE IS
SOME TIMING DIFFERENCES WITH THE TWO SYSTEMS, THERE IS GOOD
AGREEMENT THAT MOISTURE TRANSPORT FROM THE PLAINS WILL BE MAINLY
TO OUR SOUTHEAST. THERE WILL BE ENOUGH MOISTURE AND FORCING ON
THE NORTH SIDE OF THE PLAINS LOW FOR SHOWERS THURSDAY AFTERNOON
AND EVENING, WITH THE CANADIAN LOW CURRENTLY LAGGING A BIT
BEHIND AND MAINLY RESULT IN COLD ADVECTION SHOWERS THURSDAY
NIGHT.
WEEKEND:
THE AFOREMENTIONED LOWS WILL MERGE OVER THE GREAT LAKES LEADING TO A
STRONG PRESSURE GRADIENT SETTING UP OVER THE NORTHLAND. GUSTY NORTH
WINDS WITH AMPLE COLD AIR POURING IN FROM THE NORTH WILL LEAD TO A
VERY CHILLY SATURDAY MORNING WITH LOWS IN THE 20S. DRY AIR WILL ALSO
DOMINANT MOST THE REGION LEADING TO MOSTLY SUNNY SKIES AND
HIGHS CONTINUING TO BE IN THE 50S AND 60S. THE DRY AND WINDY
CONDITIONS MAY PROMPT FIRE WEATHER CONCERNS FOR SATURDAY.
