DISCUSSION
ISSUED AT 136 PM CDT THU JUL 23 2026
IT'S ANOTHER BEAUTIFUL JULY DAY AS A BROAD SURFACE HIGH
STRETCHES ACROSS MUCH OF THE GREAT LAKES REGION. INCREASING
SOUTHERLY FLOW ON ITS WESTERN PERIPHERY WILL SUPPORT A GRADUAL
WARMING TREND HEADING INTO THE WEEKEND. HIGHS ARE EXPECTED TO
PEAK ON SATURDAY THROUGH MONDAY WITH WIDESPREAD 90S LIKELY EACH
DAY. HEAT IMPACTS WILL BE A CONCERN, ESPECIALLY WITH DEWPOINT
TEMPERATURES RANGING BETWEEN 65 TO 75 DEGREES. THIS WILL RESULT
IN AFTERNOON HEAT INDICES APPROACHING 100F EACH DAY. THE HEAT
CONTINUES INTO THE WEEK, THOUGH WITH THE RIDGE EXPECTED TO
WEAKEN AND A PASSING SHORTWAVE OR TWO IN THE FLOW ALOFT, WE
SHOULD SEE SOME RELIEF FROM THE HEAT. IT MAY NOT BE MUCH, BUT IT
WILL FEEL BETTER THAN NOTHING.
OUR RAIN CHANCES WILL REMAIN LIMITED OVER THE NEXT 7 DAYS,
THOUGH THERE IS AN INCREASING SIGNAL FOR AT LEAST SOME
SCATTERED STORMS SUNDAY PM. A VERY MOIST AND UNSTABLE AIRMASS
WILL BE IN PLACE ACROSS THE REGION AS A SUBTLE IMPULSE IN THE
FLOW SPREADS EAST FROM THE DAKOTAS. FOR ANY STORMS THAT DEVELOP
WITHIN THIS FORCING, IT WILL BE A PRIME ENVIRONMENT FOR SEVERE
WEATHER GIVEN THE INCREASING LLJ AND SEVERAL THOUSAND J/KG OF
MUCAPE. THERE IS SOME UNCERTAINTY WITH TIMING AS WELL, BUT LATE
AFTERNOON INTO THE EVENING WOULD BE FAVORED AS THE EML DEEPENS.
A 15% RISK FOR SEVERE WEATHER IS CENTERED OVER MN AND WI FOR THE
DAY 4 SWO.
IT SHOULD BE HIGHLIGHTED AS WELL THAT THERE IS A DAY 2 SLIGHT
RISK ACROSS PORTIONS OF NORTHERN MN AND EASTERN ND. THERE ARE
SOME INDICATIONS THAT DECAYING STORMS COULD CONTINUE INTO
CENTRAL MN FRIDAY EVENING, THOUGH INSTABILITY QUICKLY DECREASES
THE FURTHER SOUTH THE STORMS TRAVEL WHICH SHOULD LIMIT THEIR
MOBILITY.
UNDER THIS BUILDING RIDGE, NORTHWESTERLY FLOW ALOFT MAY USHER IN
PERIODS OF ELEVATED SMOKE FROM WILDFIRES ACROSS WESTERN NORTH
AMERICA. THE IMPACTS FROM THIS WOULD BE MORE IF HIGHER
CONCENTRATIONS WERE EXPECTED TO BE AT THE SURFACE, BUT IT IS
WORTH NOTING SINCE IT COULD STILL BE NOTICEABLE IN THE SKY AT
THE VERY LEAST.
