SHORTWAVE TROUGH LIFTING NORTHEAST OUT OF COLORADO AND ASSOCIATED
SURFACE FEATURE NEAR THE COLORADO-KANSAS STATE LINE WILL PROVIDE
LIFT FOR SCATTERED THUNDERSTORM DEVELOPMENT THIS AFTERNOON AND
EVENING. MODEST INSTABILITY BUT WEAK DEEP LAYER SHEAR MAY YIELD A
FEW STORMS WITH SMALL HAIL BUT OVERALL SEVERE THREAT RATHER LOW.
ACTIVITY WILL GRADUALLY SHIFT EASTWARD THROUGH THE LATE EVENING
AND OVERNIGHT HOURS...ENDING BY AROUND 12Z.

SHORTWAVE RIDGING WILL BUILD OVER THE HIGH PLAINS EARLY WEDNESDAY
BUT A WEAK SYSTEM IS FORECAST TO MOVE THROUGH THE RIDGE AXIS IN
THE AFTERNOON. WEAK TO MODERATE INSTABILITY WILL BE IN PLACE
ACROSS THE NORTHEAST PORTION OF THE FORECAST AREA...ROUGHLY NORTH
OF A YUMA TO HILL CITY LINE...WHERE WIDELY SCATTERED THUNDERSTORMS
WILL DEVELOP DURING AFTERNOON PEAK HEATING HOURS. DEEP LAYER SHEAR
CONTINUES TO BE LESS THAN 20KTS SO THE THREAT FOR SEVERE STORMS

WEAK FRONTOGENESIS WITH THIS FEATURE AND IT IS POSSIBLE FOR A FEW

WEATHER DISTURBANCE THAT THE ECMWF/GFS/SREF BRING INTO THE WESTERN

THURSDAY NIGHT. GOOD DYNAMICS AND RIGHT REAR PORTION OF UPPER JET

KANSAS/NEBRASKA BORDER. LOCALLY HEAVY RAINFALL POSSIBLE. WILL
CONTINUE WITH A CHANCE OF SHOWERS/STORMS EARLY FRIDAY MORNING BEFORE
DECREASING THEM FROM NORTH TO SOUTH AS SOME DRIER AIR MOVES IN.
HOWEVER...PLENTY OF INSTABILITY AROUND AND POSSIBLY A FRONTAL
BOUNDARY SO CANT COMPLETELY RULE OUT PRECIP DURING THE REST OF THE
DAY.

THURSDAY GENERALLY UPPER 80S TO LOW 90S. FOR FRIDAY HIGHS GENERALLY
IN THE 80S.

NORMAL IN THE UPPER 80S TO LOW 90S WITH OVERNIGHT LOWS IN THE 60S.
