ACTIVE WATCHES...WARNINGS...AND ADVISORIES ON THE GREAT LAKES CAN
BE FOUND AT...HTTP://WWW.CRH.NOAA.GOV/GREATLAKES/?C=HAZ&L=GL&P=A

5 DAY ICE DISCUSSION...
A LOW WILL MOVE EAST ACROSS SOUTHERN CANADA THROUGH FRIDAY PULLING A
TRAILING COLD FRONT ACROSS THE LAKES. HIGH PRESSURE WILL THEN PUSH
EAST ACROSS THE LAKES LATE FRIDAY INTO SATURDAY NIGHT. A COLD FRONT
WILL DROP SOUTHEAST ACROSS THE LAKES STARTING SATURDAY UNTIL
STALLING NEAR LAKE ERIE ON SUNDAY THEN REMAINING THERE INTO THE
MIDDLE OF NEXT WEEK.

ABOVE TO MUCH ABOVE NORMAL TEMPERATURES ARE EXPECTED ACROSS THE
LAKES THURSDAY COOLING TO NORMAL TO BELOW NORMAL FOR
SATURDAY...SUNDAY AND MONDAY. THE WARMER TEMPERATURES THROUGH FRIDAY
SHOULD LEAD TO RAPID ICE DETERIORATION...THEN COOLER AIR ARRIVING ON
THE WEEKEND THROUGH EARLY NEXT WEEK WILL SLOW ICE DETERIORATION OVER
THE NORTH HALF OF THE LAKES...ESPECIALLY AROUND LAKE SUPERIOR. THE
PERSISTENT CLOUD COVER OVER THE SOUTHERN PART OF THE LAKES SUNDAY
THROUGH THE MIDDLE OF NEXT WEEK WILL ALSO SLOW ICE MELTING.

THE SOUTH TO SOUTHEAST WINDS AHEAD OF THE COLD FRONT THROUGH
THURSDAY THAT WILL APPROACH GALE FORCE IN PLACES WILL LIKELY CAUSE A
NORTHWARD PUSH TO THE ICE FIELDS. AS WINDS TURN TO THE WEST TO
NORTHWEST BEHIND THE COLD FRONT...THE ICE FIELDS WILL THEN SHOW A
EAST TO SOUTHEAST SHIFT THURSDAY NIGHT THROUGH EARLY SATURDAY. LATER
SATURDAY THROUGH MONDAY...WINDS SHOULD STAY LIGHT ENOUGH TO HAVE
LITTLE EFFECT ON THE ICE FIELDS.
