DISCUSSION
ISSUED AT 134 PM CDT TUE JUL 14 2026
..SYNOPSIS
RIDGING WILL GRADUALLY FLATTEN AND MOVE EAST TODAY INTO WEDNESDAY,
ALLOWING COOLER AIR TO SETTLE INTO THE AREA, ESPECIALLY NORTH OF
HIGHWAY 200. HIGHS ALONG THE INTERNATIONAL BORDER ON WEDNESDAY WILL
BE NEAR OR JUST ABOVE 80 DEGREES, WITH A SHARP GRADIENT AROUND THE
HIGHWAY 200 CORRIDOR, THEN LOW TO MID 90S TO THE SOUTH. THERE WILL
BE A SLIGHT REBOUND OF WARMER TEMPS FURTHER NORTH ON THURSDAY AND
FRIDAY AS THE WESTERN SIDE OF THE RIDGE BUILDS BACK INTO THE AREA
THROUGH THE WEEKEND. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
COULD FORM ALONG THE FRONT AND INTO THE POST-FRONTAL ENVIRONMENT
EACH AFTERNOON TODAY THROUGH FRIDAY. ADDITIONAL SHOWERS AND
THUNDERSTORMS WORK BACK INTO THE FORECAST THIS WEEKEND, BUT WILL
DEPEND ON THE TIMING OF ANOTHER SLOW MOVING COLD FRONT. THIS SHOULD
SERVE TO BRING TEMPERATURES BACK TOWARDS SEASONAL AVERAGES BY THE
MIDDLE OF NEXT WEEK.
..HEAT IMPACTS THIS WEEK
AREAS TO THE SOUTH OF A SLOW MOVING COLD FRONT ARE EXPECTED TO
REMAIN QUITE WARM THROUGH THE END OF THIS WEEK. AFTERNOON TEMPS IN
THE 90S WILL COMBINE WITH DEW POINTS GENERALLY IN THE UPPER 60S TO
LOW 70S TO BRING HEAT INDEX VALUES OF AROUND 100 DEGREES EACH
AFTERNOON. THE BEST CHANCES TO SEE THESE HIGHER HEAT INDICES WILL BE
IN THE SOUTHERN RED RIVER VALLEY AND ADJACENT AREAS OF SOUTHEAST
NORTH DAKOTA AND WEST CENTRAL MINNESOTA. TEMPERATURES IN THE CENTRAL
RED RIVER VALLEY COULD CLIMB BACK INTO THE LOW 90S; HOWEVER, LOWER
DEW POINTS SHOULD KEEP HEAT INDEX VALUES IN THE MIDDLE TO UPPER
90S.
AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/
ISSUED AT 1233 PM CDT TUE JUL 14 2026
VFR CONDITIONS PREVAIL AT ALL TAF SITES THIS AFTERNOON. LOOK FOR
AN ISOLATED THUNDERSTORM OR TWO NORTH OF KTVF AS A COLD FRONT
CONTINUES SOUTHEASTWARD ACROSS THE AREA. WINDS WILL SHIFT TO THE
NORTH AND NORTHEAST FOLLOWING THE FRONT THIS AFTERNOON AND
EVENING, GENERALLY IN THE RANGE OF 7-12 KNOTS, BUT WITH A FEW
GUSTS UP TO 25 KNOTS AT KDVL. AS THE WIND SHIFTS AND INCREASES,
THERE COULD BE BRIEF PERIODS OF LLWS TONIGHT INTO EARLY
WEDNESDAY MORNING.
