.DISCUSSION...
CLOSED UPPER LOW CONTINUES TO MOVE ACROSS WISCONSIN AND INTO THE
GREAT LAKES REGION WHILE RIDGING MOVES OVER THE ROCKIES. NEXT
UPSTREAM TROF IS CURRENTLY OFF THE BRITISH COLUMBIA COAST WHICH
WILL BRING UNSETTLED WEATHER INTO THE REGION OVER THE WEEKEND. AT THE
SFC...LOW PRESSURE CENTER CONTINUES TO MOVE NORTHEAST OF THE AREA.
CLOUDS AND A FEW SHOWERS CONTINUE TO ROTATE AROUND THIS BUT SHOULD
BE CLEAR OF THE AREA BY LATE EVENING HOURS AS WE LOSE DAYTIME
HEATING.
AREA OF SFC HIGH PRESSURE MOVES EAST TOWARD THE REGION OVERNIGHT
AND OVERHEAD ON THURSDAY WHILE UPSTREAM UPPER LOW PROGRESSES INTO
THE PACIFIC NORTHWEST. RETURN LOW LEVEL FLOW WL SET UP BY EARLY
SATURDAY WITH A FEW WEAK UPPER LEVEL WAVES MOVING OUT AHEAD OF SWRN
TROF. SOME ELEVATED INSTABILITY COULD SPAWN TSTMS SATURDAY AS A
WARM FRONT BEGINS TO PUSH NORTH OUT OF KANSAS. THIS FRONTAL
BOUNDARY LOOKS TO REMAIN NEAR THE KS/NEB BORDER THRU THE WEEKEND
AND WILL BE THE FOCUS FOR CONTINUED TSTM DEVELOPMENT.
IN THE EXTENDED PERIODS...FAIRLY QUIET WEATHER IS EXPECTED OVER
THE FORECAST AREA AS UPPER LEVEL RIDGE TRIES TO BUILD OVER THE
CONUS. A FEW WEAK WAVES MOVING THRU THIS FLOW COULD BRING A FEW
BOUTS OF SHOWERS AND TSTMS...BUT NOTHING LOOKS SIGNIFICANT AT THIS
POINT.
