A CLIPPER CONTINUES TO TRAVERSE THE NORTHLAND THIS AFTERNOON,
BRINGING CLOUDY SKIES AND WIDESPREAD LIGHT SNOW AND PATCHY
FREEZING DRIZZLE. WHILE ACCUMULATIONS FOR MOST AREAS WILL REMAIN
IN THE 1 TO 2 INCH RANGE, SOUTHWESTERLY FLOW MAY SLIGHTLY
INTERACT WITH THE TERRAIN ALONG THE NORTH SHORE ENHANCING
SNOWFALL RATES, WHERE ISOLATED TOTALS OF 3 TO 4 INCHES ARE
POSSIBLE. ANY ICING IS ANTICIPATED TO ONLY BE A LIGHT GLAZE.
SATELLITE CLOUD TOP PHASE RGB'S AND RADAR DUAL POL SIGNATURES
HIGHLIGHT THE FZDZ AREAS QUITE WELL WITH NICE AREAS OF NEAR-ZERO
ZDR AND HIGH CC IN THE PRESENCE OF REFLECTIVITY IN THE SYSTEM'S
DRY SLOT.
AS THE SYSTEM EXITS TO THE EAST THIS EVENING, A COLD FRONT WILL
SWEEP ACROSS THE REGION. WINDS WILL SHIFT FROM SOUTHWEST TO
NORTHWEST AND REMAIN GUSTY, USHERING IN A COLDER AIRMASS. ANY
LINGERING SNOW SHOWERS WILL TAPER OFF FROM WEST TO EAST TONIGHT.
OVERNIGHT LOWS ARE EXPECTED TO DROP INTO THE SINGLE DIGITS
ABOVE AND BELOW ZERO, WITH WIND CHILL VALUES DIPPING AS LOW AS
20 DEGREES BELOW ZERO BY MONDAY MORNING.
HIGH PRESSURE BUILDS IN FOR THE START OF THE WORK WEEK, BRINGING
CLEARING SKIES BUT KEEPING TEMPERATURES ON THE COOLER SIDE FOR
MONDAY. A GRADUAL WARMING TREND KICKS IN TUESDAY AND WEDNESDAY
AS TEMPERATURES CLIMB BACK INTO THE 20S. ATTENTION THEN TURNS TO
THURSDAY, WHEN A MORE ORGANIZED CLIPPER/LOW PRESSURE SYSTEM IS
FORECAST TO MOVE THROUGH THE UPPER MIDWEST. THIS SYSTEM WILL
LIKELY DRAW WARM AIR NORTHWARD, PUSHING HIGHS INTO THE 30S AND
INTRODUCING THE POTENTIAL FOR A MESSY MIX OF RAIN AND SNOW WITH
SNOWFALL AMOUNTS GIVING ANOTHER INCH OR TWO IF WE STAY IN THE
COLDER AIR.
