THE MAIN UPPER TROUGH CONTINUES TO ROTATE TO OUR NORTH OVER
CENTRAL CANADA, WITH COOLER AIR ALOFT ALLOWING FOR A FAIR AMOUNT
OF CUMULUS TO DEVELOP OVER THE REGION THIS AFTERNOON. THE CLOUD
COVER WILL DISSIPATE AFTER SUNSET, LEAVING SURFACE HIGH
PRESSURE AND DEW POINTS IN THE 40S. AT THIS POINT THINK WE
SHOULD STAY ABOVE THE 40 MARK OVERNIGHT, BUT A FEW SPOTS COULD
GET INTO THE LOW TO MID 40S. A COUPLE OF THE MODEL RUNS HAVE
SOME LIGHT PRECIP ALONG THE CANADIAN BORDER TOMORROW AS A
REINFORCING SHORTWAVE ROUNDS THE BASE OF THE UPPER TROUGH, BUT
NBM PROBS OF ANYTHING MEASURABLE ARE LESS THAN 10 PERCENT. A
STRONGER SHORTWAVE MOVING THROUGH COULD BRING A FEW SHOWERS
THURSDAY AFTERNOON AND EVENING, BUT MAIN IMPACTS LOOK TO BE
BRIEF DOWNPOURS AND SOME LIGHTNING AS SURFACE BASED CAPE LOOKS
PRETTY LIMITED AND SHOULD REMAIN UNDER 1000 J/KG. SLIGHTLY
COOLER AND QUIET ON FRIDAY AS A COLD FRONT AND THEN HIGH
PRESSURE COME DOWN BEHIND THE SHORTWAVE.
ENSEMBLES ARE IN PRETTY GOOD AGREEMENT ON NORTHWESTERLY FLOW
ALOFT CONTINUING THROUGH THE WEEKEND AND INTO THE START OF NEXT
WEEK, WITH VARIOUS WEAK SHORTWAVES MOVING THROUGH. NBM HAS KEYED
IN ON ONE OF THOSE SHORTWAVES COMING THROUGH SUNDAY NIGHT AND
INTO MONDAY BRINGING FAIRLY HIGH PROBABILITIES OF AT LEAST 0.01
OF PRECIP. GIVEN UNCERTAINTY WITH THE TIMING OF SUCH FEATURES IN
THE LONG TERM SEE LITTLE REASON TO CHANGE IT AT THIS POINT.
TEMPERATURES SEEM FAIRLY SEASONABLE WITH HIGHS IN THE UPPER 70S
TO LOW 80S AND LOWS IN THE 50S.
AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/
ISSUED AT 1216 PM CDT TUE AUG 4 2026
VFR CONDITIONS WITH SOME CUMULUS CLOUDS FORMING THIS AFTERNOON,
BUT THINK THAT COVERAGE WILL BE SCATTERED AND IF ANY CEILINGS DO
FORM THEY WILL BE OVER 3000 FT. CUMULUS WILL DISSIPATE AFTER
SUNSET, AND OUR WINDS THAT ARE GUSTING UP AROUND 20 KTS IN SOME
SPOTS FROM THE NORTHWEST WILL ALSO DECREASE DOWN BELOW 8 KTS.
WINDS WILL PICK UP AGAIN OUT OF THE SOUTHWEST BY TOMORROW
MORNING, WITH A FEW SPOTS GUSTING ABOVE 20 KTS AGAIN.
