- CLIPPER BRINGS LIGHT SNOW TONIGHT INTO MONDAY
LIGHT SNOW MOVES IN LATE TONIGHT INTO MONDAY MORNING WITH 1-2
INCHES ALONG THE LAKESHORE AND AN INCH OR LESS FURTHER INLAND.
LIGHT SNOW PAIRED WITH TEMPERATURES IN THE TEENS TO LOW 20S WILL
BRING SLICK SPOTS FOR THE MONDAY MORNING COMMUTE.
THE SHORTWAVE TROUGH THAT WILL BRING OUR ROUND OF LIGHT SNOW
OVERNIGHT INTO MONDAY IS CURRENTLY OVER WESTERN WISCONSIN AND WILL
GRADUALLY MOVE EAST REACHING THE LAKESHORE AROUND MIDNIGHT.
MOISTURE IS NOT THAT DEEP, NOR IS THE BEST LIFT IN THE DENDRITIC
GROWTH ZONE, THEREFORE SNOWFALL RATES SHOULD REMAIN LIGHT.
PROBABILITIES OF 2 OR MORE INCHES ARE FOCUSED IN MUSKEGON,
OCEANA, AND MASON COUNTIES WHERE THE FETCH OFF THE LAKE IS THE
BEST FOR SOME LAKE ENHANCED SNOW. THEREFORE SOME ISOLATED POCKETS
UP TO 3 INCHES IS POSSIBLE (30 TO 50 PERCENT). THE BEST MOISTURE
EXITS THE REGION MONDAY MORNING WITH THE POTENTIAL FOR SOME
LINGERING LIGHT SHOWERS INTO THE AFTERNOON. WE WILL HAVE TO
MONITOR FOR SOME FREEZING DRIZZLE LATE MONDAY MORNING INTO THE
AFTERNOON AS THE SHALLOW MOISTURE MAY LACK CLOUD ICE.
- ANOTHER CLIPPER BRINGING SNOW THURSDAY NIGHT INTO FRIDAY
DRY CONDITIONS ARE EXPECTED DUE TO SURFACE RIDGING TUESDAY INTO
THURSDAY BEFORE ANOTHER CLIPPER SYSTEM SWINGS THROUGH THURSDAY
NIGHT INTO FRIDAY. THE PLACEMENT AND STRENGTH OF THE LOW STILL
VARIES, BUT THERE IS A TREND TOWARD LOWER PROBABILITIES OF 2
INCHES OR MORE (20 TO 40 PERCENT) AND 4 INCHES OR MORE (20
PERCENT) SINCE YESTERDAY'S FORECAST. OVERALL LOOKING LIKE ANOTHER
LIGHT WIDESPREAD SNOW EVENT THAT COULD BRING SOME SLICK SPOTS FOR
THE FRIDAY MORNING COMMUTE.
BEHIND THE COLD FRONT FRIDAY TEMPERATURES WILL FALL WITH LAKE
EFFECT SHOWERS LIKELY DEVELOPING AND CONTINUING THROUGH THE
WEEKEND. FRIDAY WILL BE OUR WARMEST DAY OF THE WEEK WITH
TEMPERATURES APPROACHING 30 DEGREES.
