NATIONAL WEATHER SERVICE GOODLAND KS
505 PM MDT THU MAY 7 2015

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 1209 PM MDT THU MAY 7 2015

SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG THE FRONT RANGE AND
PALMER DIVIDE THIS AFTERNOON AS THE NEXT SHORTWAVE TROUGH COMES UP
IN THE SOUTHWESTERLY FLOW ALOFT. THESE STORMS WILL GRADUALLY SHIFT
EASTWARD TONIGHT WITH THE WESTERN HALF OF THE FORECAST AREA
FAVORED. THERE IS A SLIM CHANCE FOR OTHER STORMS THAT DEVELOP
ALONG THE COLD FRONT IN SOUTHWEST KANSAS TO MAKE IT THIS FAR
NORTH. SHEAR AND INSTABILITY PARAMETERS ARE NOT PARTICULARLY
IMPRESSIVE...BUT CANNOT RULE OUT AN ISOLATED SEVERE STORM MAINLY
IN COLORADO EARLY THIS EVENING BEFORE LOSS OF SURFACE HEATING.
OVERNIGHT AND INTO FRIDAY MORNING...SCATTERED LIGHT SHOWERS AND
PERHAPS AN ISOLATED THUNDERSTORM WILL GRADUALLY DIMINISH WITH TIME
AS THEY CONTINUE TO MOVE NORTHEAST. FAVORABLE LOW LEVEL UPSLOPE
AND MOIST LOW LEVELS WILL RESULT IN LOW CLOUDS AND AREAS OF FOG BY
DAWN...MAINLY IN SOUTHWESTERN AREAS.

THE SET UP FOR FRIDAY WILL BE SIMILAR TO TODAY. ANOTHER SHORTWAVE
TROUGH IN THE SOUTHWESTERLY FLOW ALOFT WILL PROVIDE SYNOPTIC SCALE
FORCING FOR AFTERNOON SHOWER AND THUNDERSTORM DEVELOPMENT. BEST
CHANCES FOR SEVERE STORMS WILL BE SOUTH OF HIGHWAY 40 WHERE
INSTABILITY AND SHEAR WILL BE MAXIMIZED...THOUGH PROBABILITIES
WILL BE HIGHEST JUST SOUTH OF THE LOCAL AREA. MORNING CLOUDS WILL
BE SLOW TO ERODE DUE TO PERSISTENT UPSLOPE AND MAY PLAY A ROLE IN
LIMITING AFTERNOON INSTABILITY.
