A TIGHTENING PRESSURE GRADIENT BETWEEN HIGH PRESSURE CENTERED OVER
THE SOUTHEAST US AND LOW PRESSURE OVER EASTERN ONTARIO WILL MAKE FOR
BREEZY CONDITIONS THROUGH THE EVENING. WESTERLY WINDS COULD GUST AS
HIGH AS 25 TO 30 MPH. WINDS WILL SUBSIDE SHORTLY AFTER SUNSET. SKIES
WILL BE MOSTLY CLEAR TONIGHT, WHICH WILL MAKE FOR FAVORABLE VIEWING
CONDITIONS FOR POSSIBLY SEEING THE NORTHERN LIGHTS TONIGHT!
TEMPERATURES WILL FALL INTO THE 30S THIS EVENING. CLOUDS INCREASE
AFTER MIDNIGHT FROM WEST TO EAST.
THE NEXT FEW DAYS WILL BE DRY. INCREASING WAA THROUGH THE WEEK WILL
ALLOW FOR TEMPERATURES TO MODERATE BACK TOWARDS SEASONABLE LEVELS BY
THE END OF THE WORK WEEK. BREEZY SOUTHERLY WINDS ON SATURDAY WILL
HELP BOOST HIGH TEMPERATURES INTO THE 60S AREA-WIDE, WITH SOME
LOCATIONS SOUTH OF US 24 APPROACHING 70 DEGREES!
A LOW PRESSURE SYSTEM WILL LIFT THROUGH THE UPPER MIDWEST INTO
ONTARIO ON SATURDAY. IT'S ATTENDANT WARM FRONT MAY BRING ISOLATED
SPRINKLES SATURDAY MORNING, WITH ADDITIONAL CHANCES FOR RAIN
ARRIVING SATURDAY AFTERNOON AND EVENING WITH THE SYSTEM'S ATTENDANT
COLD FRONT. MOISTURE RETURN FROM THE GULF IS DISJOINTED OUT AHEAD OF
LIFT FROM THE COLD FRONT, SO HAVE KEPT CHANCES AT 20-40% FOR NOW,
BUT WOULDN'T BE SURPRISED IF SATURDAY TRENDS MAINLY DRY IN THE
COMING DAYS. BEHIND THE FRONT, TEMPERATURES EARLY NEXT WEEK DROP TO
NEAR SEASONABLE LEVELS FOR THIS TIME OF YEAR IN THE UPPER 40S TO LOW
50S.
