GREAT LAKES ICE OUTLOOK
NATIONAL WEATHER SERVICE CLEVELAND OHIO
512 PM EDT MON APR 14 2014

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 PRESSURE SYSTEM WILL MOVE EAST OF THE GREAT LAKES REGION
TUESDAY FOLLOWED BY AREAS OF SNOW MAINLY OVER SOUTHERN LAKE HURON
AND LAKES ERIE AND ONTARIO. HIGH PRESSURE OVER THE DAKOTAS WILL MOVE
OVER THE GREAT LAKES WEDNESDAY. TEMPERATURES WILL BE 20 TO 30
DEGREES BELOW NORMAL WITH THE COLD AIRMASS IN PLACE THROUGH LATE
WEEK. TEMPERATURES WILL BEGIN TO REBOUND BACK TOWARDS NORMAL AS THE
AREA OF HIGH PRESSURE SLIDES EAST AND WARMER SOUTHERLY FLOW MOVES
INTO THE GREAT LAKES. AN AREA OF LOW PRESSURE WILL BRING SNOW TO
LAKE SUPERIOR THURSDAY BUT THE PRECIPITATION WILL LIKELY FALL AS
RAIN AS THE LOW MOVES OVER LAKES MICHIGAN AND HURON FRIDAY.

THE TEMPERATURES BELOW FREEZING EARLY THIS WEEK WILL SLOW THE ICE
ROTTING ON THE LAKES. HOWEVER THE INCREASED SOLAR RADIATION WITH THE
LONGER DAYS AND GRADUAL WARMING OF THE LAKE WATER TEMPERATURES WILL
SUPPORT A SLOW REDUCTION IN ICE CONCENTRATION DESPITE FREEZING
TEMPERATURES. OVERALL...VESSELS WILL STILL HAVE A DIFFICULT TIME
MAKING THEIR WAY THROUGH THE ICE FIELDS...PARTICULARLY OVER THE
NORTHERN LAKES.  VESSELS SHOULD BE CAUTIONED FOR THE POTENTIAL FOR
BECOMING TRAPPED IN THE ICE FLOES.
