UPDATE
ISSUED AT 341 AM CDT TUE SEP 1 2026
A CLUSTER OF WEAKENING THUNDERSTORMS IN EASTERN COLORADO/NORTHWEST
KANSAS ARE PUSHING TO THE NORTHEAST WITH SCATTERED STORMS CONTINUING
THROUGH SUNRISE. THE TREND OF HOT TEMPS CONTINUES WITH HIGHS
REACHING INTO THE UPPER 80S-LOW 100S. HEAT INDEX VALUES WILL BE IN
THE 90S-100S FOR THE ENTIRE AREA.
OVER THE LATE EVENING/OVERNIGHT HOURS STORM CHANCES RETURN TO THE
AREA. SUFFICIENT CAPE AND SHEAR ARE PRESENT FOR THE DEVELOPMENT OF
STRONG TO SEVERE STORMS. STORM DEVELOPMENT WILL DEPEND ON THE PATH
OF A WEAK FRONTAL SYSTEM MOVING THROUGH THE AREA. CURRENT GUIDANCE
SUGGESTS STORMS WILL FORM ALONG THE FRONT IN THE SANDHILLS TRACKING
EAST-NORTHEAST. THE BEST CHANCE FOR STORMS STAYS TO THE NORTH OF I-
80 OR WEST OF HWY-183. THE BIGGEST THREAT FOR SEVERE STORMS REMAINS
TO THE NORTH, IN THE SANDHILLS AND SOUTH DAKOTA.
THE GENERAL PATTERN OF TROUGHING TO THE WEST OF THE ROCKIES AND
RIDGING OVER THE PLAINS/MIDWEST REMAINS IN PLACE THROUGH THE END OF
THE WEEK KEEPING THE SOUTHWEST FLOW IN PLACE. WITH THIS PATTERN,
WARM TEMPS, WITH HIGHS IN THE UPPER 80S-90S EXPECTED TO CONTINUE
INTO THE EARLY PART OF SEPTEMBER. ADDITIONALLY ANY
DISTURBANCES/SHORTWAVES MOVING THROUGH THE PATTERN WILL CONTINUE TO
PROVIDE LOW CHANCES (10-20%) OF STORMS ON ANY GIVEN DAY.

THE COUNTRY AND TEXAS NORTHWARD TO NEBRASKA AND PORTIONS OF THE
MIDWEST. AN UPPER LOW IS CENTERED OVER SOUTHERN CANADA AND EXTENDS
SOUTHWARD OVER THE NORTHERN PLAINS AND PORTIONS OF THE UPPER
MIDWEST. WINDS ACROSS SOUTH CENTRAL AND CENTRAL NEBRASKA AND NORTH
CENTRAL KANSAS ARE FAIRLY LIGHT AT AROUND 5 TO 10 MPH AND ARE
TRANSITIONING TO THE SOUTH TO SOUTHEAST. HIGH TEMPERATURES TODAY
WILL RANGE FROM THE MID 80S TO UPPER 90S ACROSS THE FORECAST AREA. A
SHORTWAVE TROUGH IS EXPECTED TO MOVE OVER/NEAR THE AREA LATE THIS

DEVELOPING AND MOVING ACROSS MAINLY AREAS ALONG AND TO THE WEST AND
NORTH OF THE TRI-CITIES AREA BEGINNING AROUND 1 AM AND CONTINUING
UNTIL AROUND OR SLIGHTLY PAST SUNRISE. CAPE, WIND SHEAR, AND LAPSE
RATES WILL BE SUFFICIENT FOR SOME OF THESE STORMS TO BECOME STRONG
TO MARGINALLY SEVERE. HAIL UP TO AROUND QUARTER SIZE AND WIND GUSTS
UP TO AROUND 60 MPH WILL BE POSSIBLE WITH THE STRONGEST STORMS. A
SURFACE LOW WILL BE NEAR/ACROSS THE AREA TONIGHT WITH LOW

INTO THE AREA TUESDAY EVENING INTO TUESDAY NIGHT. SHOWERS AND STORMS

ALONG THIS FRONT AND ASSOCIATED WITH AN UPPER DISTURBANCE MOVING
OVER/NEAR THE AREA. THESE STORMS WILL HAVE THE POTENTIAL TO BECOME
STRONG TO SEVERE GIVEN HIGH CAPE AND FAIRLY HIGH WIND SHEAR AND
LAPSE RATES. LARGE HAIL AND DAMAGING WINDS WILL BE THE MAIN THREATS.

EXPECTED TO GO AWAY 2 TO 3 HOURS AFTERWARDS. LOW TEMPERATURES
TUESDAY NIGHT WILL GENERALLY RANGE FROM THE LOW/MID 60S TO THE
MID/UPPER 70S.
