DISCUSSION
ISSUED AT 311 PM CDT SAT SEP 5 2026
LABOR DAY WEEKEND...EAST/NORTHEAST LOW-LEVEL WINDS FROM HIGH
PRESSURE OVER ONTARIO AND THE GREAT LAKES HAS ALLOWED FOR A SHALLOW
LAYER OF LOW-LEVEL MOISTURE AND CLOUDS TO PREVAIL ACROSS MUCH OF THE
REGION THROUGHOUT THE MORNING AND INTO THIS AFTERNOON. ANTICIPATE
THESE CLOUDS TO GRADUALLY DISSIPATE BY THIS EVENING WITH THE LOSS OF
DAYTIME HEATING. SKIES WILL BE MOSTLY CLEAR OVERNIGHT, WITH THE
POTENTIAL FOR PATCHY FOG TO DEVELOP EARLY SUNDAY MORNING. EXPECT DRY
CONDITIONS AND ABOVE NORMAL TEMPERATURES (HIGHS RANGING FROM THE
UPPER 70S TO LOW 80S) TO CONTINUE THROUGH THE REMAINDER OF THE LABOR
DAY WEEKEND AS THE HIGH PRESSURE AND UPPER-LEVEL RIDGING REMAIN IN
PLACE. PATCHY FOG MAY DEVELOP LATE SUNDAY NIGHT INTO MONDAY MORNING
AS WELL.
REST OF THE FORECAST...THE RIDGE AND HIGH PRESSURE WILL GRADUALLY
DEPART LATE MONDAY AS RETURN FLOW SETS UP AHEAD OF AN APPROACHING
SYSTEM/WEAK COLD FRONT PROGGED TO MOVE OVER THE AREA LATE MONDAY
THROUGH EARLY WEDNESDAY MORNING. IT IS TOO EARLY TO DETERMINE THE
SEVERE POTENTIAL, BUT THIS PATTERN WOULD FAVOR STRONG/SEVERE STORMS
IF THE STORMS MOVE THROUGH DURING PEAK HEATING ON TUESDAY. WILL
CONTINUE TO MONITOR OVER THE COMING DAYS. MAINLY DRY CONDITIONS
RETURN FOR THE REMAINDER OF WEDNESDAY THROUGH EARLY FRIDAY.
