DISCUSSION
ISSUED AT 132 PM CDT FRI OCT 3 2025
MORNING CLOUDS CONTINUE TO DISSIPATE, BUT A NARROW BAND OF BRIEF
SHOWERS REMAINS ONGOING NORTH OF THE METRO. THE CLOUDS AND
SHOWERS WILL CONTINUE TO BREAK UP AND SHOULDN'T LAST MORE THAN
AN HOUR OR SO IN ANY GIVEN LOCATION GOING FORWARD. IN THE WAKE
OF THE CLOUD COVER, TEMPERATURES HAVE STARTED TO SKYROCKET
ACROSS SOUTHERN AND WESTERN MN AND ST. JAMES REACHED 90 AS EARLY
AS 1215 PM. OTHER READINGS EARLY THIS AFTERNOON ARE IN THE MID
TO UPPER 80S, SO THERE'S LITTLE DOUBT WE'RE GOING TO HAVE
WIDESPREAD LOW 90S LATER THIS AFTERNOON WEST OF I-35. THIS IS
WELL IN LINE WITH MIXING DOWN 925 MB TEMPS OF +26 TO +27C AND
MEETS OR EXCEEDS THE NBM 95TH PERCENTILE. IT'S THE SAME STORY
SATURDAY, PERHAPS A DEGREE OR TWO WARMER, SO I WOULDN'T BE
SURPRISED TO SEE A FEW LOCATIONS REACH THE MID 90S ACROSS
WESTERN MN.
LIGHT SOUTHERLY WINDS ARE IN PLACE NOW, BUT THEY WILL BEGIN
INCREASING OVERNIGHT AS A LOW LEVEL JET DEVELOPS FROM THE
SOUTHERN HIGH PLAINS TO MN AHEAD OF AN APPROACHING TROUGH. A
45-50 KT LLJ STREAK WILL SCOOT OVERHEAD SATURDAY AFTERNOON.
MIXING IS EXPECTED TO DEEPEN TO JUST BELOW THAT LEVEL. WHILE
THERE WILL BE NEAR CONTINUOUS 30-35 KT GUSTS, ROGUE GUSTS
GREATER 40 KTS ARE ALSO POSSIBLE.
A POTENT SURFACE LOW WILL TRACK FROM CENTRAL SD TO NORTHWEST
MN SATURDAY NIGHT. A TRAILING COLD FRONT WILL REACH WESTERN MN
LATE SUNDAY MORNING AND THE I-35 CORRIDOR LATE AFTERNOON OR
EARLY EVENING. THE THERMAL RIDGE WON'T BE AS IMPRESSIVE AS
SATURDAY, ALTHOUGH THERE REMAINS GOOD POTENTIAL FOR STRONG
HEATING JUST PRIOR TO THE FRONT. IT WON'T BE AS HOT, BUT GUSTY
WINDS WILL CONTINUE. MODELS HAVE ALSO BECOME A BIT MORE
OPTIMISTIC FOR SOME SHOWERS AND STORMS TO DEVELOP ALONG THE
FRONT FROM MID AFTERNOON ONWARD, AND DESPITE THE DRY BOUNDARY
LATER, FORECAST SOUNDINGS DO SHOW MODEST SURFACE-BASED
INSTABILITY.
MUCH COOLER AND DRIER AIR WILL ARRIVE BEHIND THE FRONT AND
SURFACE HIGH PRESSURE WILL BUILD IN MONDAY AND TUESDAY. THE HIGH
APPEARS A LITTLE WEAKER AND NOT CENTERED OVERHEAD TUESDAY NIGHT
AS IT WAS YESTERDAY, SO THE RISK OF A WIDESPREAD FROST OR FREEZE
IS ALSO LOWER. STILL, LOWS IN THE 30S AND 40S WITH PATCHY FROST
WILL BE A BIG CHANGE FROM THIS WEEKEND. THE HIGH WILL MOVE OFF
TO THE EAST FOR LATER NEXT WEEK AND SOUTHERLY FLOW WILL RETURN.
TEMPERATURES SHOULD RETURN BACK TO ABOVE NORMAL LEVELS WITH 70S
(AND EVEN SOME 80S PER ECMWF) NOT OUT OF THE QUESTION.
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
ISSUED AT 605 PM CDT FRI OCT 3 2025
THE 00Z TAF LARGELY MIRRORS THE 18Z WITH SKC TO SCT250 AND VFR
ACROSS ALL LOCATIONS THROUGHOUT THE PERIOD. THE PRIMARY CONCERN
WILL BE WINDS FAVORING 150 TO 180 INCREASING TO 15-20KTS GUSTING
FROM 30-35KTS AFTER 17-18Z. LLWS WILL ALSO BE A CONCERN AS THE
STRONGER WINDS ARRIVE AS THE SYSTEM APPROACHES FROM THE WEST,
PRIMARILY FROM 04-14Z WITH SPECIFIC INTERVALS WITHIN THE TAF
PERIOD, AND OVERALL WEAKER/LOWER DURATION LLWS FOR EASTERN TAF
SITES.
KMSP...A SLIGHT BUMP UP IN PEAK GUST POTENTIAL TO 30KTS IS THE
ONLY REAL CHANGE WITHIN THE TAF, WITH LLWS STILL INCLUDED FROM
05-14Z AND SUSTAINED WINDS FROM 15-20KTS AFTER 17Z.
