SITUATED ALONG A FRONTAL BOUNDARY ACROSS SOUTHERN SASKATCHEWAN
TO START THIS EVENING. THIS BOUNDARY WILL MOVE SOUTH-SOUTHEAST
TONIGHT, WITH SHOWERS AND INCREASING CLOUDS WEST AND NORTH
CENTRAL. THIS CONTINUES THURSDAY MORNING ACROSS THE REMAINDER OF
THE AREA, WITH WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS
DURING THE DAY THURSDAY. OVERALL, CHANGES TO THE FORECAST WITH
THIS UPDATE WERE MINIMAL, AND MAINLY FOCUSED ON TIMING OF THE
ARRIVAL OF POPS AND LOW LEVEL CLOUDS.
DISCUSSION
ISSUED AT 221 PM CDT WED JUN 10 2026
ISOLATED TO SCATTERED SHOWERS ARE EXPECTED TO CONTINUE THIS
AFTERNOON AND EVENING OVER MUCH OF THE STATE, EXCEPT THE SOUTHWEST.
THERE HAVE BEEN A FEW RUMBLES OF THUNDER, ESPECIALLY EAST OF
HIGHWAY 85. HOWEVER, WITH MARGINAL INSTABILITY AND ENHANCED
SHEAR MOVING OFF TO THE EAST, SEVERE THUNDERSTORMS ARE NOT
ANTICIPATED FOR THE FORECAST AREA. WINDY CONDITIONS WILL ALSO
CONTINUE THROUGH THIS AFTERNOON BEFORE BECOMING LIGHTER, ALBEIT
STILL BREEZY, THIS EVENING AND OVERNIGHT.
TONIGHT THROUGH THURSDAY WILL SEE INCREASING PRECIPITATION CHANCES
AS UPPER LOW OVER MANITOBA GRADUALLY CHURNS EASTWARD, WHILE
SHORTWAVE ENERGY AND ASSOCIATED SURFACE TROUGH SLIDES THROUGH THE
NORTHERN PLAINS. THIS WILL RESULT IN SCATTERED SHOWERS AND
THUNDERSTORMS AT TIMES GENERALLY STARTING AND ENDING FROM NORTHWEST
TO SOUTHEAST. OVERALL, PRECIPITATION TOTALS ARE EXPECTED TO BE
LIGHT, THOUGH HIGHER AMOUNTS ARE POSSIBLE WITH ANY THUNDERSTORM
ACTIVITY. IN ADDITION TO SHOWERS AND THUNDERSTORMS, WINDY
CONDITIONS ARE EXPECTED ON THURSDAY AS THE SURFACE TROUGH
SIGNIFICANTLY TIGHTENS THE GRADIENT. MODERATE CAA AND MODEST
PRESSURE RISES COULD RESULT IN ADVISORY LEVEL WINDS THURSDAY,
ESPECIALLY IN THE SOUTHWEST.
AFOREMENTIONED UPPER LOW VERY SLOWLY MEANDERS EASTWARD THROUGH
THE REMAINDER OF THE WEEK AND INTO EARLY NEXT WEEK... ONLY
PROGRESSING ABOUT AS FAR AS ONTARIO/HUDSON BAY. THEREFORE, WHILE
THE NBM PRODUCES A MOSTLY DRY FORECAST FRIDAY THROUGH EARLY
NEXT WEEK, EMBEDDED SHORTWAVE ENERGY IN NORTHERLY/NORTHWESTERLY
FLOW ALOFT COULD PRODUCE OCCASIONAL SHOWERS AND THUNDERSTORMS.
IN ADDITION, BREEZY TO WINDY CONDITIONS ARE EXPECTED MOST DAYS
THROUGH THE REMAINDER OF THE WEEK. OF FINAL NOTE, COOLER
TEMPERATURES, USUALLY BELOW AVERAGE, WILL PREVAIL THROUGH AT
LEAST THE WEEKEND AND LIKELY INTO EARLY NEXT WEEK.
AVIATION /00Z TAFS THROUGH 00Z FRIDAY/
ISSUED AT 657 PM CDT WED JUN 10 2026
A FEW ISOLATED SHOWERS ARE PRESENT IN THE NORTHWEST ALONG WITH
AN EXPANDING MID LEVEL CLOUD DECK NORTH. MOSTLY DRY CONDITIONS
ARE EXPECTED THIS EVENING BEFORE MORE WIDESPREAD SHOWERS SPREAD
FROM NORTHWEST TO SOUTHEAST ACROSS MOST OF THE STATE TONIGHT
THROUGH THURSDAY MORNING. THESE SHOWERS WILL BRING MVFR CEILINGS
WITH THE POTENTIAL FOR POCKETS OF IFR CEILINGS TO DEVELOP.
WINDY CONDITIONS OUT OF THE WEST WILL LET OFF A BIT THIS EVENING
BEFORE SWITCHING TO THE NORTHWEST LATE TONIGHT AND BECOMING
GUSTY ON THURSDAY.
