- SOME SNOW IN MASON AND OCEANA COUNTIES ALONG THE LAKESHORE
OVERALL OTHER THAN SOME LIGHT FLURRIES MOST OF THE AREA WILL BE
DRY THROUGH WEDNESDAY. WITHIN THE NORTH TO NORTHEAST FLOW THIS
EVENING AN AREA OF CONVERGENCE WILL DEVELOP OVER LAKE MICHIGAN
CREATING A NARROW BAND OF SNOW. THIS BAND OF SNOW MAY CLIP
PORTIONS OF MASON AND OCEANA COUNTIES TONIGHT INTO WEDNESDAY
PROVIDING A DUSTING TO AN INCH OF SNOW THROUGH WEDNESDAY
AFTERNOON.
- NEXT ROUND OF WIDESPREAD SNOW THURSDAY INTO FRIDAY
WARM AIR ADVECTION MOVES IN FOR THURSDAY BRINGING ANOTHER ROUND OF
SNOW DURING THE DAY ALONG WITH SOME ADDITIONAL SUPPORT FROM
POSITIVE VORTICITY ADVECTION WITH A QUICK MOVING SHORTWAVE TROUGH.
AS THIS LIFT EXITS MOISTURE BECOMES MORE SHALLOW AND WE'LL NEED TO
MONITOR FOR FREEZING DRIZZLE THURSDAY NIGHT INTO EARLY FRIDAY
MORNING.
ANOTHER SHORTWAVE TROUGH AND ASSOCIATED POSITIVE VORTICITY
ADVECTION MOVE THROUGH FRIDAY MORNING BRINGING BACK THE DEEPER
MOISTURE FOR SNOWFALL THROUGH THE REST OF FRIDAY MORNING BEFORE
DRY CONDITIONS RETURN. TOTAL SNOWFALL AMOUNTS WILL LARGELY BE 2
INCHES OR LESS WITH AREAS NORTHWEST OF GRAND RAPIDS HAVING THE
BETTER CHANCES (20 TO 40 PERCENT) OF SEEING 2-3 INCHES.
TEMPERATURES FRIDAY ARE EXPECTED TO WARM INTO THE MID 30S FOR MUCH
OF THE AREA BEFORE THE COLDER AIR ADVECTS INTO THE REGION.
- COLD THIS WEEKEND THE MODERATING TEMPERATURES NEXT WEEK
BEHIND THE COLD FRONT 850MB TEMPERATURES FALL TO AROUND -18 C WITH
LIMITED MOISTURE BEHIND THE FRONT. LOW INVERSION HEIGHTS AND DRIER
AIR WILL NOT BRING A FAVORABLE ENVIRONMENT FOR LAKE EFFECT SNOW.
THEREFORE ONLY EXPECTING COLD TEMPERATURES WITH HIGHS IN THE TEENS
TO LOW 20S AND LOWS AROUND ZERO AWAY FROM LAKE MICHIGAN. THIS DIP
IN TEMPERATURES WILL BE SHORT LIVED AS WE GRADUALLY WARM UP SUNDAY
INTO NEXT WEEK WHERE WE COULD SEE TEMPERATURES RISE ABOVE FREEZING
AGAIN.
