GREAT LAKES ICE OUTLOOK
NATIONAL WEATHER SERVICE CLEVELAND OHIO
530 PM EST FRI FEB 20 2015

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...
ARCTIC AIR WILL REMAIN ENTRENCHED OVER THE GREAT LAKES THROUGH THE
FORECAST PERIOD WITH WELL BELOW NORMAL TEMPERATURES CONTINUING INTO
NEXT WEEK.  A FAST MOVING LOW PRESSURE SYSTEM WILL MOVE ACROSS THE
OHIO VALLEY AND THEN THE EASTERN GREAT LAKES ON SATURDAY.  BEHIND IT
A LARGE AREA OF ARCTIC AIR WILL MOVE SOUTHEAST ACROSS THE LAKES THEN
MOVE OFF THE SOUTHEAST COAST TUESDAY.  THIS WILL BE FOLLOWED BY
ANOTHER ARCTIC FRONT THAT WILL PUSH ACROSS ALL THE LAKES LATE
TUESDAY INTO WEDNESDAY FOR ANOTHER SHOT OF REINFORCING COLD AIR.

TEMPERATURES WILL BEGIN FALLING SATURDAY AS ARCTIC AIR MOVES OVER
THE LAKES.  THE COLDEST AIR WILL BE OVER THE LAKES MONDAY MORNING
WITH LOWS ACROSS LAKE SUPERIOR OF -10 TO -20 WITH TEMPS OF ZERO TO
-10 ACROSS THE REMAINDER OF THE LAKES.  THIS WILL ALLOW FOR THE
EXPANSION OF ICE COVERAGE AND ADD TO THE THICKNESS OF THE ICE. THIS
MAY BE ENOUGH TO COMPLETELY FREEZE OVER LAKE SUPERIOR AND ADD TO THE
ICE COVERAGE ON LAKES MICHIGAN AND ONTARIO.

THE WINDS ACROSS THE NORTHERN AND CENTRAL LAKES WILL REMAIN FROM THE
NORTHWEST THROUGH THE WEEKEND.  WINDS ACROSS THE EASTERN LAKES WILL
TURN TO THE SOUTH-SOUTHWEST SATURDAY...AS THE LOW MOVES ACROSS THE
EASTERN LAKES.  WINDS WILL SHIFT TO THE NORTHWEST SATURDAY NIGHT AS
THE LOW SHIFTS EAST.  STRONGEST WINDS ON THE LAKES WILL OCCUR MONDAY
NIGHT INTO TUESDAY AS WINDS SHIFT TO THE SOUTHWEST-WEST AND INCREASE
TO NEAR 30 KNOTS LATE MONDAY INTO TUESDAY AHEAD OF NEXT ARCTIC
BOUNDARY.  THIS MAY CAUSE RIDGING AND RAFTING OF ICE FIELDS AND
CREATE ICE FLOES.  IN ADDITION ANY TRACKS THAT HAVE BEEN OPENED DUE
TO ICE BREAKER OPERATION WILL LIKELY CLOSE.
