GREAT LAKES ICE OUTLOOK
NATIONAL WEATHER SERVICE CLEVELAND OHIO
515 PM EDT WED APR 15 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...
LARGE AREA OF HIGH PRESSURE CENTERED OVER LAKE SUPERIOR WILL SLIDE
EAST AND MOVE OFF THE NEW ENGLAND COAST THURSDAY EVENING...ALLOWING
A WARM FRONT TO LIFT ACROSS THE WESTERN AND CENTRAL LAKES.   THE
FRONT WILL LIFT ACROSS THE EASTERN LAKES THURSDAY NIGHT.  LOW
PRESSURE WILL MOVE NORTH ACROSS THE WESTERN LAKES SUNDAY LIFTING
ANOTHER WARM FRONT ACROSS THE LAKES.   THIS WILL BE FOLLOWED BY A
COLD FRONT THAT WILL SWEEP ACROSS THE LAKES MONDAY.

LIGHT SOUTH WINDS ACROSS THE WESTERN LAKES WILL TURN TO THE
NORTHWEST THURSDAY NIGHT.  LIGHT AND VARIABLE WINDS ACROSS THE
EASTERN AND CENTRAL LAKES WILL TURN TO THE NORTHWEST FRIDAY.

NORMAL TEMPERATURES THURSDAY...WILL GIVE WAY TO ABOVE NORMAL
TEMPERATURES ACROSS ALL THE LAKES THAT WILL LAST THROUGH THE END OF
THE WEEKEND.    THE REMAINING ICE FIELDS WILL CONTINUE TO
DETERIORATE THROUGH THE WEEKEND.   LAKE ERIE IS ICE FREE FROM ABOUT
FAIRPORT HARBOR WEST. ICE PERSISTS IN THE STRAITS OF MACKINAC AND
OVER THE EASTERN PORTION OF LAKE HURON AND MUCH OF THE EASTERN HALF
OF LAKE SUPERIOR.

THE WIND THE NEXT FEW DAYS WILL ONLY HAVE A MINOR IMPACT ON
DECREASING THE ICE COVERAGE. THE WARMER TEMPERATURES WILL HAVE THE
MOST IMPACT ON DECREASING THE ICE COVERAGE...NONE THE LESS IT WILL
BE A SLOW PROCESS.

THE ICE FLOES SHOULD NOT BE SHIFTING THAT MUCH FOR MUCH OF THE WEEK
BECAUSE OF GENERALLY LIGHT WINDS EXPECTED.
