DISCUSSION
ISSUED AT 112 PM EDT FRI OCT 9 2026
PATTERN SYNOPSIS/FORECAST:
UPPER LEVEL HEIGHTS ON THE REBOUND AS LONG-WAVE RIDGING BUILDS INTO
THE NORTHERN GREAT LAKES EARLY THIS AFTERNOON. OVERHEAD RIDGE
BUILDING PART OF A MATURING LONG-WAVE AMPLIFICATION PROCESS...DRIVEN
IN LARGE PART BY DEEP TROUGHING BUILDING INTO THE WESTERN NOAM.
THOSE BUILDING HEIGHTS AND ATTENDANT DEEP LAYER SUBSIDENCE RESULTING
IN MOSTLY SUNNY SKIES TODAY, WITH THAT SUNSHINE HELPING TEMPERATURES
RETURN TO NEAR OR A BIT ABOVE SPECIFIC NORMAL VALUES FOR TODAY'S
DATE (CURRENT READINGS IN THE 50S AND 60S).
UPPER LEVEL RIDGING WILL CONTINUE TO MATURE AS IT CENTERS ITSELF
ACROSS THE AREA THIS WEEKEND. CURRENT GULF OF AMERICA HURRICANE
ISAIAS WILL CONTINUE TO PIVOT RAPIDLY NORTH, EVENTUALLY CUTTING UP
INTO THE TENNESSEE AND OHIO RIVER VALLEYS LATER THIS WEEKEND. RIDGE
DOES BEGIN TO BREAK DOWN HEADING THROUGH NEXT WEEK AS VARIOUS PIECES
OF ENERGY OUT OF UPSTREAM TROUGHING EJECT EAST ACROSS CENTRAL NOAM.
PRIMARY FORECAST CONCERNS:
TEMPERATURE TRENDS AND ADDRESSING ANY SHOWER POTENTIAL THROUGH THE
PERIOD.
DETAILS:
BIGGEST STORY FOR THIS WEEKEND WILL BE THE WELL ABOVE NORMAL
TEMPERATURES...FUELED BY THOSE BUILDING OVERHEAD HEIGHTS AND
INTENSIFYING RETURN FLOW ON THE BACKSIDE OF DEPARTING SURFACE HIGH.
TOP-DOWN THERMAL PROFILES EASILY SUPPORT HIGHS BOTH SATURDAY AND
SUNDAY UP INTO THE 70S FOR MOST, WITH PERHAPS SOME AREAS OF
NORTHWEST LOWER MICHIGAN MAKING A RUN AT 80 ON SATURDAY WHEN SOUTH
WIND PRODUCED DOWNSLOPE WARMING WILL BE MOST NOTABLE. CONDITIONS
SHOULD LARGELY REMAIN DRY, ALTHOUGH WILL NEED TO WATCH THE NORTHERN
EXTENT OF DEEPER MOISTURE TIED TO DECAYING ISAIAS LATE SATURDAY
NIGHT/EARLY SUNDAY AS IT PIVOTS NORTHEAST THROUGH THE LOWER OHIO
VALLEY (ALTHOUGH CURRENT TRENDS SUPPORT ANY RAINS REMAINING JUST TO
OUR SOUTHEAST).
START OF NEXT WORK WEEK AGAIN LOOKS MILD, ALTHOUGH EXACT
TEMPERATURES DETAILS WILL BE DICTATED BY TIMING OF SLOW SOUTHEAST
DIVING COLD FRONT. LOOKS LIKE AREAS SOUTH OF THE BIG BRIDGE REMAIN
IN THE WARM SECTOR MUCH OF THE DAY, SUPPORTING HIGHS BACK UP INTO
THE 70S. PERHAPS A BIT COOLER ACROSS EASTERN UPPER OWNING TO THE
PASSING FRONT. STILL, EASILY LOOKING AT WELL ABOVE NORMAL
TEMPERATURES UP INTO THE 60S EVEN UP THERE. FRONT WILL SLOWLY WORK
SOUTH ACROSS THE AREA MONDAY NIGHT. WHILE THE VAST MAJORITY OF
DEEPER MID LEVEL SUPPORT BECOMES DETACHED TO OUR NORTH, PROBABLY
STILL LOOKING AT THE THREAT FOR A FEW SHOWERS ALONG AND JUST BEHIND
THE FRONT LATER MONDAY INTO EARLY TUESDAY.
TEMPERATURES DEFINITELY LOOK TO TREND TO MORE NORMAL-LIKE LEVELS FOR
THE REST OF NEXT WEEK. WEATHER DOES LOOK TO POTENTIALLY BECOME A
TOUCH MORE ACTIVE THE SECOND HALF OF THE WEEK AS CORE OF WESTERN
TROUGHING ROTATES NORTHEAST INTO THE CENTRAL PLAINS AND NORTHERN
CONUS. PLUME OF DEEPER SUBTROPICAL MOISTURE WILL LIKELY ACCOMPANY
THIS TROUGHING AND ATTENDANT MATURING COLD FRONT...DRIVING GOOD
POTENTIAL FOR SOME MUCH NEEDED RAINS. TIMING SUBJECT TO CHANGE OF
COURSE, BUT DEFINITELY LOOKING AT SOME WET WEATHER POTENTIAL AT
TIMES WEDNESDAY NIGHT THROUGH FRIDAY.
