.SHORT TERM...(TONIGHT)
ISSUED AT 310 PM MDT FRI JUN 5 2015
THE MAIN CONCERNS LATE THIS AFTERNOON AND EVENING IS THE THREAT OF
SEVERE THUNDERSTORMS ALONG WITH THE POTENTIAL FOR FLASH FLOODING.
FORTUNATELY THE ATMOSPHERE OVER MUCH OF THE CWA STABILIZED
FOLLOWING MORNING SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A
QUICK MOVING SHORTWAVE. IT WILL TAKE A FEW HOURS FOR THE BOUNDARY
LAYER TO DESTABILIZE BUT EXPECTING THUNDERSTORMS TO REDEVELOP LATE
THIS AFTERNOON. THE MODELS CONTINUE TO STRUGGLE SHOWING WHERE AND
WHEN STORMS WILL OR WILL NOT DEVELOP. MOST LIKELY THUNDERSTORMS
WILL DEVELOP ALONG THE LARAMIE THE LARAMIE RANGE LATE AFTERNOON
AND THEN SHOULD PUSH NORTHEAST INTO THE PLAINS DURING THE EVENING.
SHOULD ANY THUNDERSTORM BECOME STATIONARY OR BACK BUILD...FLASH
FLOODING THREAT WILL INCREASE...SUCH AS OCCURRED YESTERDAY. THE
FLOW ALOFT IS SOMEWHAT STRONGER...SO MOST LIKELY STORMS WILL NOT
REMAIN STATIONARY BUT COULD STILL SEE A FEW TRAINING THUNDERSTORMS.

NORTHEAST SFC WINDS DEVELOPING DURING THE DAY ON SUNDAY WITH SOME
GOOD QPF AMOUNTS. AIRMASS WILL LIKELY BE TOO STABLE FOR A SVR
RISK...WITH ONLY ISOLATED EMBEDDED TSTMS.
MONDAY-WEDNESDAY:
DRYING AND WARMING WILL OCCUR BY EARLY NEXT WEEK. WEAK MIDLVL
DISTURBANCE OVER COLORADO ON MONDAY WILL BE PUSHED SOUTHEAST BY
TUESDAY AS AN UPPER LEVEL RIDGE BUILDS OVER WYOMING. WITH NONE OF
THE MODELS INDICATING MUCH QPF AND SIGNIFICANT RIDGING
ALOFT...LARGELY KEPT POPS BELOW 20 PERCENT.
THURSDAY:
THE GFS AND ECMWF ARE IN GENERAL AGREEMENT AT SHOWING AN UPPER
TROUGH MOVING INTO UTAH-COLORADO BY THURSDAY. FRONTAL PASSAGE ON
WED NIGHT/THURS MORNING WILL USHER IN COOLING ALONG WITH A BETTER
CHANCE OF PRECIP. WENT WITH WIDESPREAD 30-40 POPS SINCE THE LONG
