EVEN HOTTER TEMPERATURES TODAY, WITH HIGHS FORECAST TO REACH THE
MID 90S MOST LOCATIONS, AND EVEN THE UPPER 90S FAR SOUTHWEST.
THIS WILL LEAD TO HEAT INDEX VALUES IN THE MID TO UPPER 90S.
THUNDERSTORMS ARE POSSIBLE BY LATE THIS AFTERNOON, WITH ONE
FOCUS ALONG A PRE-FRONTAL SURFACE TROUGH, DRAPED FROM NEAR
CHAMBERLAIN SOUTH DAKOTA THROUGH VALENTINE, BACK TO THE
SOUTHWEST THROUGH OSHKOSH IN GARDEN COUNTY. SOME OF THE LATEST
CAMS INCLUDING THE 3KM NAM DEVELOP CONVECTION ALONG THIS
BOUNDARY, ESPECIALLY FROM SOUTH DAKOTA INTO CHERRY COUNTY. IF
STORMS DO FORM ALONG THIS BOUNDARY, UPSCALE GROWTH MAY LEAD TO A
CLUSTER OR CLUSTERS OF STORMS DEVELOPING SOUTHEAST INTO NORTH

STORMS INITIATING IN THE WESTERN SANDHILLS WILL MOVE EAST
THROUGH THE EVENING HOURS. PLENTY OF INSTABILITY AVAILABLE, WITH
SPCAPES AS HIGH AS 3000 TO OVER 4000 J/KG. LARGE HAIL AND
DAMAGING WINDS, ESPECIALLY FROM OUTFLOW FROM STORM CLUSTERS ARE
THE MAIN THREATS. LOCALLY HEAVY RAIN IS ALSO POSSIBLE, GIVEN
PWATS FROM 1.25 TO 1.5 INCHES AVAILABLE. THE ACTIVITY SHOULD
MOVE INTO PORTIONS CENTRAL AND EASTERN NEBRASKA LATE EVENING
INTO THE OVERNIGHT HOURS.
ON SUNDAY, A COLD FRONT WILL PUSH THROUGH THE FORECAST AREA,

TO THE THE MID TO UPPER 80S SOUTHWEST. THERE A 5 TO 8 DEGREE
SPREAD BETWEEN THE 25TH AND 75TH PERCENTILE MAX TEMPERATURES,
SO CONFIDENCE IN HIGHS IS BELOW AVERAGE. REGARDING POPS, CHANCES
INCREASE TO ABOUT 40 PERCENT SUNDAY AFTERNOON AS THE SURFACE
FRONT STALLS NEAR THE NEBRASKA/KANSAS BORDER. THERE IS ALSO A
MARGINAL RISK FOR SEVERE STORMS ACROSS THE ENTIRE AREA, MEANING
