DISCUSSION
A SEASONABLY STRONG 1020 MB SURFACE HIGH WILL REMAIN ANCHORED OVER
THE GREAT LAKES TODAY AND TOMORROW, SUPPORTING CONTINUED SUBSIDENCE,
LIGHT WINDS, AND A DRY/STABLE COLUMN. UNIDIRECTIONAL NORTHEAST FLOW
THROUGH THE LOW-LEVELS DID PRODUCE STRONG 0-3KM LAPSE RATES WHICH
HAVE AIDED IN SPARSE CU DEVELOPMENT ACROSS THE IRISH HILLS AND METRO
REGION. THE FEW-SCT CLOUD DECK WILL ERODE AROUND SUNSET, LEADING TO
CLEAR SKIES OVERNIGHT WITH LOWS RIGHT AROUND 50 DEGREES. THE OVERALL
LONGWAVE OMEGA BLOCK PATTERN WILL START TO BREAK DOWN TOMORROW AS
THE MEANDERING CLOSED LOW SYSTEM ACROSS THE ROCKIES RELEASES
EASTWARD AHEAD OF A DEEPENING PACIFIC NW TROUGH. THIS WILL FOLD THE
RIDGE AXIS ACROSS THE GREAT LAKES TOMORROW AND WILL GREATLY REDUCE
AMPLIFICATION OF THE WAVE. THIS WILL MUTE THE INFLUENCE OF NORTHEAST
FLOW TOMORROW AND WILL ALLOW TEMPERATURES TO PUSH INTO THE 80S UNDER
MOSTLY SUNNY CONDITIONS, OUTSIDE OF SOME TRANSLUCENT CIRRUS THAT
WILL STREAM IN THROUGH THE DAY. WINDS BACK TO THE SOUTHWEST ON
THURSDAY WHICH FOLD THE WARMER TEMPERATURES IN THE PLAINS INTO THE
GREAT LAKES, PUSHING HIGHS IN THE MID TO UPPER 80S.
THE NEXT LIKELY CHANCE FOR RAIN AND SOME THUNDERSTORMS WILL ENTER
FRIDAY INTO SATURDAY ONCE THE PACIFIC NW WAVE EXTENDS INTO THE
MIDWEST, EVENTUALLY PUSHING THE TROUGH INTO MICHIGAN. CONFIDENCE
TURNS LOWER SURROUNDING POP CHANCES INTO EARLY NEXT WEEK PENDING THE
ARRIVAL AND PLACEMENT OF A LOW PRESSURE SYSTEM ORIGINATING FROM
TEXAS. THIS IS PROJECTED TO STALL OUT SOUTH OF MICHIGAN AS HIGH
PRESSURE DROPS FROM CANADA INTO MICHIGAN.
MARINE
HIGH PRESSURE SITS ATOP THE GREAT LAKES REGION THROUGHOUT TODAY INTO
WEDNESDAY. AS THE HIGH PRESSURE MOVES OVERHEAD, LIGHT WINDS FROM THE
NORTHEAST BECOME VARIABLE. BY THURSDAY, WINDS OUT OF THE SOUTHWEST
ARE EXPECTED AS THE HIGH MOVES INTO THE MID-ATLANTIC. THE NEXT
CHANCE OF RAIN AND THUNDERSTORMS ARE GREATEST FRIDAY NIGHT INTO
SATURDAY AS A COLD FRONT APPROACHES THE AREA, WHICH IS EXPECTED TO
BRING BREEZY CONDITIONS AS WELL.
