DISCUSSION
ISSUED AT 231 PM CDT WED JUL 8 2026
..SYNOPSIS
ZONAL FLOW ACROSS THE NORTHERN CONUS TODAY WILL GRADUALLY GIVE
WAY TO MORE MERIDIONAL FLOW BY THIS WEEKEND AS RIDGING BUILDS
ACROSS THE ROCKIES AND PLAINS. CLUSTERS THEN DEPICT A COUPLE
STRONGER WAVES RIDING ALONG THE PERIPHERY OF THE RIDGE IN
INTERIOR CANADA. THIS COULD HAVE IMPACTS REACHING SOME OF THE
LOCAL THRESHOLDS FOR HEAT ADVISORIES OR EVEN AN EXTREME HEAT
WARNING THIS WEEKEND SO THE IMPACT OF THESE WAVES IN THE
PLACEMENT AND AMPLITUDE OF THE RIDGE WILL CERTAINLY BE SOMETHING
TO WATCH. ALONG WITH THESE WAVES COMES CHANCES FOR SOME
SCATTERED RAIN THOUGH NO DROUGHT BUSTERS. THE MAIN RAIN CHANCE
TO BE AWARE OF LOOKS TO BE THURSDAY EVENING/OVERNIGHT MAINLY
ACROSS OUR EASTERN NORTH DAKOTA COUNTIES WITH CHANCE FOR SOME
STRONG TO SEVERE ACTIVITY.
- THURSDAY SEVERE RISK
AMID MOSTLY ZONAL TO SLIGHTLY NW FLOW WILL COME A SHORTWAVE
TOMORROW WITH A DEVELOPING LOW LEVEL JET IN THE EVENING AHEAD
THE PACIFIC TROUGH. AS MOISTURE SURGES NORTH IN CENTRAL NORTH
DAKOTA WITH DEWPOINTS NEARING 70 POTENTIALLY THERE WILL BE NO
SHORTAGE CAPE WITH UPWARDS OF 3000-4000 MUCAPE AND ENOUGH SHEAR
ALONG CLOCKWISE CURVED HODOGRAPHS FOR INITIALLY ROBUST SUPERCELL
STRUCTURES. CAPABLE OF GOLF BALL SIZED HAIL AND POTENTIALLY A
FEW TORNADOES THOUGH A LATER INITIATION TIME MAY SHUNT THE
TORNADO THREAT (AN EARLIER STORM START TIME MAY YIELD A HIGHER
THREAT.) REGARDLESS AS STORMS WORK EAST INTO OUR FORECAST AREA
AND NAMELY THE DEVILS LAKE BASIN AROUND 7-9PM THEY SHOULD
TRANSITION TO A MORE ELEVATED MODE AND THE SURFACE BEGINS TO
COOL WITH THE CESSATION OF DAYTIME HEATING AND HAZARDS WILL
EVOLVE TO PRIMARILY HAIL AND AN INCREASING WIND THREAT STORMS
LIKELY CONGEAL INTO ONE OR MORE LINES/BOWING SEGMENTS. HAZARDS
FOR OUR AREA ARE HAIL TO 1.75" AND WINDS TO 60MPH.
- HEAT IMPACTS
FOR THIS WEEKEND AS HEAT BUILDS THERE IS HIGH CONFIDENCE IN
MUCH OF EASTERN NORTH DAKOTA SEEING AIR TEMPERATURES CRESTING 90
DEGREES AS EARLY AS SATURDAY AND LASTING THROUGH AT LEAST
MONDAY WHEN HIGHS FALL BACK INTO THE 80S FOR THE MIDDLE OF NEXT
WEEK. DURING THIS STRETCH THE 25-75TH PERCENTILE SPREAD ON
POTENTIAL HIGH TEMPERATURES IS A REASONABLE 5-8 DEGREES MEANING
WHILE TEMPS COULD END UP SLIGHTLY WARMER OR COOLER THAN
CURRENTLY BEING FORECAST IT IS UNLIKELY HIGHS WILL ONLY BE IN
THE LOWER 80S RATHER THAN LOWER 90S. ALONG WITH THE WARM TEMPS
WILL BE HEAT INDICES NEAR TO ABOVE 100 SATURDAY THROUGH MONDAY.
WITH THIS HEAT HEADLINES LOOK TO BE IN ORDER WITH SUNDAY BEING
THE HOTTEST DAY OF THE STRETCH. WILL WAIT UNTIL TOMORROW AT THE
EARLIEST TO ISSUE ANY HEADLINES FOR SATURDAY BUT IT WILL BE A
PROPER JULY SCORCHER OF A WEEKEND REGARDLESS OF ANY PRODUCTS
BEING ISSUED.
