THE REGION WILL GRADUALLY EXIT EAST INTO NEW ENGLAND TODAY AS A
LARGE UPPER RIDGE BEGINS TO EXPAND EAST INTO THE MIDWEST AND
GREAT LAKES INTO SATURDAY. MAINLY DRY AND SEASONABLE WEATHER
WILL CONTINUE AS SURFACE HIGH PRESSURE REMAINS ACROSS THE AREA.
A FEW SHOWERS OR STORMS ARE POSSIBLE ACROSS FAR NORTHEAST OHIO

SHORTWAVE MOVES EAST THROUGH THE LOWER GREAT LAKES, AIDED BY A
DEVELOPING LAKE BREEZE.

KEY MESSAGE 2...
CONFIDENCE IS INCREASING FOR A FEW STRONGER STORMS BEGINNING
LATE SUNDAY INTO TUESDAY AS SEVERAL POTENT SHORTWAVES TRAVERSE
THE BASE OF A STRONG UPPER-LEVEL TROUGH ACROSS HUDSON BAY.
THERE WILL BE A COUPLE OF PERIODS TO WATCH FOR DEVELOPING
STORMS, THE FIRST OF WHICH APPEARS TO BE SUNDAY NIGHT INTO
MONDAY AS A LEADING SHORTWAVE ENTERS THE LOWER GREAT LAKES,
THOUGH CONFIDENCE IS A BIT LOWER GIVEN THE MORE MESOSCALE
DYNAMICS AT PLAY. SLIGHTLY HIGHER CONFIDENCE EXISTS FOR A MORE
WIDESPREAD STRONG THUNDERSTORM POTENTIAL IN THE MONDAY NIGHT
INTO TUESDAY TIMEFRAME WITH CONVECTION SUPPORTED BY THE PASSAGE
OF A POTENT MID AND UPPER-LEVEL TROUGH. GIVEN THE FAVORABLE
NORTHWESTERLY SHEAR AND ANTICIPATED LINEAR STORM MODE, IF ANY
