KEY MESSAGES
- AN EXTENDED PERIOD OF DRY AND ABOVE TO MUCH ABOVE AVERAGE
TEMPERATURES THROUGH THE NEXT 7 DAYS.
DISCUSSION
ISSUED AT 142 AM CDT SUN OCT 18 2026
TODAY LOOKS TO BE THE COOLEST OF THE NEXT 7 DAYS WITH HIGHS IN
THE LOW TO MID 60S. MONDAY ONWARD HIGH TEMPERATURES SHOULD BE IN
THE UPPER 60S OR 70S EACH DAY. NO PRECIPITATION IS EXPECTED THE
NEXT 7+ DAYS WITH CLOUDLESS OR NEARLY CLOUDLESS SKIES MANY OF
THE DAYS. GUSTY SOUTHWEST WINDS WILL DEVELOP THIS AFTERNOON IN
RESPONSE TO A TIGHTENING PRESSURE GRADIENT FROM DEEP LOW
PRESSURE TRACKING ACROSS CENTRAL CANADA. IN THE WAKE OF THAT
SYSTEM SFC HIGH PRESSURE WILL BECOME ESTABLISHED OVER THE UPPER
GREAT LAKES/SOUTHEAST CANADA RESULTING IN LIGHTER WINDS MUCH OF
THE UPCOMING WORK WEEK. WEAK AFTERNOON LAKE BREEZES COULD BRING
SOME MODEST COOLING NEAR THE LAKE IN THE AFTERNOONS. A PEEK
BEYOND DAY 7 OF THE FORECAST SUGGESTS THAT THIS PATTERN COULD
PERSIST THE REST OF OCTOBER.
