SYNOPSIS
AFTER ANOTHER COLD START TO THE DAY, TEMPERATURES WILL MODERATE
ON WEDNESDAY AND INTO THE SECOND HALF OF THE WEEK TO NEAR
AVERAGE VALUES. HIGH PRESSURE KEEPS DRY CONDITIONS IN PLACE
THROUGH THE WEEKEND. THE NEXT CHANCE OF RAIN HOLDS OFF UNTIL
EARLY NEXT WEEK.
NEAR TERM /THROUGH TONIGHT/
KEY MESSAGE(S):
- LAKE WIND ADVISORY IN EFFECT UNTIL 7 PM FOR GUSTS UP TO 30 MPH ON
AREA LAKES.
- GRADUAL WARMING BEGINNING TODAY.
CLEAR SKIES CONTINUE WITH HIGH PRESSURE ACROSS THE AREA AND A VERY
DRY AIR MASS IN PLACE WITH PWATS AROUND A HALF INCH. TEMPERATURES 10
TO 15 DEGREES WARMER THAN TUESDAY, WITH HIGHS IN THE LOW TO MID 60S.
PRESSURE GRADIENT WILL ALLOW BREEZY WEST TO SOUTHWEST WINDS TO
CONTINUE THROUGH THIS AFTERNOON, WITH GUSTS OF 25-30 MPH AND A LAKE
WIND ADVISORY IN EFFECT UNTIL 7 PM TONIGHT. THE HIGH CENTERED TO OUR
SOUTHWEST SLOWLY PUSHES NORTH TONIGHT, ALLOWING THE GRADIENT TO
RELAX. EXPECT CONTINUED MODERATION FOR LOW TEMPERATURES TONIGHT,
GENERALLY FALLING INTO THE UPPER 30S AND LOW 40S.
SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/
KEY MESSAGE(S):
- DRY HIGH PRESSURE IN PLACE THROUGH FRIDAY.
DEEP NORTHWESTERLY FLOW WILL CONTINUE ACROSS THE REGION THROUGH THE
END OF THE WEEK AS SERIES OF SHORTWAVES REMAIN TO OUR NORTH. TEMPS
WILL STEADILY MODERATE EACH DAY AS THE ASSOCIATED SURFACE HIGH
SLIDES OVERHEAD AND PERSISTENTLY LOW PWAT'S ALLOW FOR PLENTY OF SUN
EACH DAY. DAYTIME HIGHS SHOULD CLIMB INTO THE LOW-MID 70'S AND
OVERNIGHT LOWS IN THE LOW 40'S.
LONG TERM /SATURDAY THROUGH TUESDAY/
KEY MESSAGE(S):
- DRY CONDITIONS EXPECTED THROUGHOUT THE LONG TERM PERIOD
DESPITE AN APPROACHING FRONT OVER THE WEEKEND.
SURFACE HIGH PRESSURE AND NORTHWESTERLY FLOW ALOFT WILL CONTINUE THE
DRY PERIOD INTO SATURDAY, SO THE WARMING TRENDS WILL CONTINUE FOR
THE FIRST HALF OF THE WEEK. A STRONG LOW WILL DIG SOUTH INTO THE
OHIO VALLEY AND PUSH A SURFACE FRONT TOWARDS OUR AREA BY SUNDAY.
DESPITE SOUTHWESTERLY FLOW AHEAD OF THE FRONT, MOISTURE IS STILL
VERY LIMITED WITH PWAT'S REMAINING BELOW 0.5". THIS FRONT IS THEN
EXPECTED TO PUSH THROUGH SUNDAY WITH WHAT LOOKS LIKE A FAIRLY WINDY
SYSTEM; EC EFI IS ALREADY HIGHLIGHTING SUNDAY FOR HIGHLY ANOMALOUS
WINDS AND GUSTS. THESE WINDS THOUGH SHOULD REMAIN UNACCOMPANIED AS
LOW PWAT'S AND RELATIVELY WEAK FORCING WILL NOT BE ABLE TO DEVELOP
MUCH IN THE WAY OF PRECIP. BEYOND SUNDAY, THE AIRMASS DOES NOT LOOK
TERRIBLY COOL, SO ONLY A MODEST COOLING TREND IS EXPECTED ALONG WITH
CONTINUED DRY CONDITIONS.
AVIATION /18Z WEDNESDAY THROUGH MONDAY/
VFR CONDITIONS EXPECTED.
SKC THROUGH THE PERIOD EXCEPT FOR QUICKLY PASSING HIGH CLOUDS
POSSIBLE LATE THIS EVENING. GUSTY WEST TO SOUTHWEST WINDS TO AROUND
20 KTS PERSIST THROUGH THIS AFTERNOON BEFORE DIMINISHING AROUND
SUNSET TONIGHT. WINDS THEN BECOME LIGHT AND VARIABLE INTO THURSDAY
MORNING. CONFIDENCE IN ANY FOG RESTRICTIONS AT THE TERMINALS IS LOW
