DISCUSSION
ISSUED AT 1106 PM CDT WED AUG 26 2026
IT WAS A QUIET AFTERNOON ACROSS THE REGION AS SURFACE HIGH
PRESSURE BUILDS INTO THE AREA. IT REMAINS QUIET TONIGHT WITH
LIGHT WINDS AND CLEAR SKIES. TEMPERATURES FALL INTO THE UPPER
50S AND LOW 60S BY SUNRISE ON THURSDAY. PATCHY FOG MAY DEVELOP,
BUT THIS SHOULD REMAIN SHALLOW AND LOCALIZED WITH LITTLE TO NO
IMPACTS EXPECTED AT THIS TIME. LIGHT WINDS AND MOSTLY SUNNY
SKIES LAST THROUGH THURSDAY AFTERNOON WITH TEMPERATURES CLIMBING
INTO THE LOW- TO MID-80S. FRIDAY'S WEATHER IS EXPECTED TO REMAIN
SIMILAR TO THURSDAY. ONLY MINOR CHANGE IS ANTICIPATED WITH
TEMPERATURES A TOUCH WARMER, INCREASING CLOUDS, AND INCREASING
SOUTHERLY WINDS BY AFTERNOON.
A SHORTWAVE TROUGH IS FORECAST TO BEGIN APPROACHING THE NORTHERN
ROCKIES AS THE PERSISTENT UPPER-LEVEL RIDGE OVER THE WESTERN
CONUS STRENGTHENS THIS WEEKEND. THESE CONCURRENT FEATURES
GRADUALLY INCREASES LEE TROUGHING ACROSS THE GREAT PLAINS. THE
RESULT WILL BE THE DEVELOPMENT OF BREEZY SOUTH TO SOUTHWEST
WINDS ON SATURDAY. WIND SPEEDS MAY APPROACH 20 MPH WITH GUSTS AS
HIGH AS 30 MPH. ON TOP OF THESE WINDS, TEMPERATURES AND MOISTURE
INCREASE. MID 90S CAN BE EXPECTED FOR HIGH TEMPERATURES ON
SATURDAY WITH HEAT INDEX VALUES PUSHING TOWARDS 100. AS THE
TROUGH DRAWS NEAR, THUNDERSTORMS ARE FORECAST OVER THE NORTHERN
PLAINS. OUR AREA MAINTAINS A LOW CHANCE OF THUNDERSTORMS
SATURDAY NIGHT INTO SUNDAY MORNING AS THE TROUGH PROGRESSES
EAST. WE REMAIN ON THE SOUTHERN END OF THIS ACTIVITY AND
EXTENDED CAM GUIDANCE IS HINTING AT THE SOUTHERN EXTEND OF
THUNDERSTORMS REMAINING NORTH OF THE REGION. OVERALL, MOST WILL
NOT SEE RAIN AS THE HEAT CONTINUES TO BUILD HEADING INTO
SUNDAY. HIGH TEMPERATURES MAY REACH THE MID- TO UPPER-90S WITH
HEAT INDEX VALUES NEAR 100, MARKING THE HOTTEST DAY IN SOME
TIME.
THANKFULLY, THE AFOREMENTIONED TROUGH HELPS TO WEAKEN AND
FLATTEN THE RIDGE HEADING INTO NEXT WEEK. SLIGHTLY COOLER
TEMPERATURES RETURN, BUT REMAIN ABOVE NORMAL IN THE MID- TO
UPPER-80S. PERIODIC THUNDERSTORM CHANCES REMAIN IN THE FORECAST
DURING THIS TIME, BUT CONFIDENCE IS LOW. RAIN CHANCES MAY
LARGELY DEPEND ON THE SOUTHERN EXTENT OF ANY PASSING WEATHER
DISTURBANCES OR ANY MESOSCALE FEATURES (FRONTS, OUTFLOW, MCV,
ETC.) THAT CAN HELP WITH THUNDERSTORM DEVELOPMENT. AS THE RIDGE
CONTINUES TO FLATTEN BY MID-WEEK, RAIN CHANCES SHOULD GRADUALLY
INCREASE.
