NORTHWESTERLY FLOW IS BRINGING A CLASSIC AUGUST FALL TEASER TODAY,
WITH BREEZY WINDS, A BROKEN ALTOCUMULUS CLOUD DECK, AND DEWPOINTS IN
THE 50S. EVEN LOWER DEWPOINTS IN THE 40S ARE EXPECTED OVERNIGHT INTO
WEDNESDAY MORNING, WHICH WILL LIKELY MAKE FOR A RELATIVELY CHILLY
NIGHT TONIGHT. EXPECT OVERNIGHT LOWS IN THE 40S FOR MOST, EXCEPT
RIGHT ALONG LAKE SUPERIOR.
RINSE AND REPEAT TOMORROW WITH A WESTERLY BREEZE IN THE AFTERNOON,
LOWER DEWPOINTS, AND HIGH TEMPERATURES IN THE 70S.
A LITTLE WIGGLE IN THE UPPER LEVEL FLOW THURSDAY SHOULD ALLOW FOR
SOME MOISTURE AND WARMTH ADVECTION BACK INTO THE AREA, WITH
DEWPOINTS IN THE MID TO UPPER 50S AND TEMPERATURES RISING INTO THE
80S. THAT IMPULSE COULD ALSO LEAD TO SOME SCATTERED SHOWERS AND
THUNDERSTORMS LATE THURSDAY THROUGH FRIDAY.
WE EXPECT TO STAY UNDER BROAD UPPER LEVEL TROUGHING INTO NEXT WEEK
WHICH WILL KEEP US ON THE SLIGHTLY COOLER SIDE. ANY UPPER LEVEL
SHORTWAVES THAT MOVE THROUGH COULD BRING SOME PASSING PRECIPITATION
CHANCES.

WINDS GUSTING 15-20MPH. A LITTLE MORE MOISTURE RETURNS THU-FRI BUT
AFTERNOON RH MAY STILL FALL INTO THE 35-40% RANGE. STRONG SOUTHWEST
