KEY MESSAGES

DISCUSSION
KEY MESSAGE 1)
DIURNAL CU, LIKELY ENHANCED SOMEWHAT BY THE FETCH OFF OF LAKE
HURON/ERIE, IS IN PLACE ACROSS OUR AREA THIS AFTERNOON. THIS SHOULD
GENERALLY DISSIPATE AS WE HEAD INTO THIS EVENING, ALTHOUGH IT MAY
LINGER A BIT LONGER ACROSS OUR EAST.
SURFACE HIGH PRESSURE WILL DRIFT EAST ACROSS THE REGION THROUGH
TONIGHT AND BE CENTERED OVER EASTERN OHIO BY SUNDAY MORNING. WITH
CLEARING SKIES AND LIGHT WINDS, EXPECT GOOD RADIATIONAL COOLING
TONIGHT WITH WIDESPREAD FROST AND SOME SUB-FREEZING TEMPERATURE.
GENERALLY EXPECT LOWS IN THE UPPER 20S TO LOWER 30S, BUT EVEN COOLER
READINGS WILL BE POSSIBLE IN OUTLYING/SHELTERED AREAS. A FREEZE
WARNING REMAINS IN EFFECT FOR TONIGHT INTO SUNDAY MORNING TO ACCOUNT
FOR THIS.
OTHERWISE, DRY CONDITIONS WILL PREVAIL THROUGH NEXT WEEK AS THE
SURFACE HIGH REMAINS IN PLACE ACROSS MUCH OF THE GREAT LAKES REGION.
EXPECT A GRADUAL WARMING TREND THROUGH MIDWEEK AS THE AIRMASS SLOWLY
MODERATES.
AVIATION /18Z SATURDAY THROUGH THURSDAY/
A BAND OF MVFR CIGS ASSOCIATED WITH MOISTURE OFF LAKE ERIE CONTINUES
TO SLOWLY SCATTER OUT THIS AFTERNOON. MOST SITES HAVE CLEARED OUT TO
VFR, BUT CAN'T RULE OUT AN OCCASIONAL MVFR CIG THROUGH THE REMAINDER
OF THE AFTERNOON. HIGH PRESSURE WILL LEAD TO CLEAR SKIES AND LIGHT
WINDS OVERNIGHT. THIS COULD RESULT IN SOME RIVER VALLEY FOG POTENTIAL
AT KLUK LATE TONIGHT INTO EARLY SUNDAY MORNING. OTHERWISE, EXPECT
VFR CONDITIONS TO PREVAIL.
AN EXTENDED PERIOD OF LIGHT WINDS AND VFR CONDITIONS FOLLOWS THROUGH
THE REST OF THE WEEKEND AND ALL OF NEXT WEEK.
OUTLOOK...NO SIGNIFICANT WEATHER EXPECTED.
