KEY MESSAGE 1...
THE RISK OF SEVERE WEATHER HAS COME TO AN END BUT CLOUDS WILL
LINGER ALONG WITH POST-FRONTAL LEFTOVER SHOWERS, AND FALLING
TEMPERATURES. THAT SAID, TEMPERATURES ONLY SETTLE MODESTLY
OVERNIGHT INTO THE 50S TO NEAR 60 FOR LOWS WHICH. WHILE COOLER
THAN THE PRIOR NIGHT, IS STILL QUITE MILD FOR MID APRIL.
KEY MESSAGE 2...
ABOVE NORMAL TEMPERATURES CONTINUE UP TO SATURDAY, BUT A RAINY
COLD FRONT IN THE EVENING WILL HERALD AN ABRUPT PATTERN FLIP TO
MUCH COOLER WEATHER FOR SUNDAY INTO MONDAY.
TEMPERATURES WILL BUMP DOWN SOME ON FRIDAY IN THE WAKE OF THE
PRIOR BATCH OF THUNDERSTORMS, YET STILL ABOVE NORMAL WITH HIGHS
OF MID 60S TO MID 70S. THERE COULD STILL BE A FEW LINGERING
SHOWERS EARLY FRIDAY, OTHERWISE PASSING HIGH PRESSURE WILL
PROVIDE FOR WINDOW OF DRY WEATHER THROUGH AT LEAST MIDDAY
SATURDAY.
AN UPPER TROUGH WILL DIG INTO THE WESTERN GREAT LAKES SATURDAY,
WITH DEEP SOUTHWEST FLOW BOOSTING TEMPERATURES WELL INTO THE 70S
ACROSS THE AREA. THIS WILL OCCUR AHEAD OF A VERY WELL-MARKED
FRONT TRAILING FROM STRONG CANADIAN LOW PRESSURE. A NARROW YET
SIGNIFICANT RIBBON OF MOISTURE WILL POOL ALL THE WAY UP FROM
THE WESTERN GULF, CAUSING RAIN AND EMBEDDED THUNDER TO SWEEP
ACROSS OUR REGION LATE SATURDAY THROUGH SATURDAY NIGHT.

HALF OF THE WEEKEND. TEMPERATURES SUNDAY WILL INITIALLY RANGE
