AREAS AFFECTED...CENTRAL HIGH PLAINS
CONCERNING...SEVERE THUNDERSTORM WATCH 479...
VALID 300310Z - 300415Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 479
CONTINUES.
SUMMARY...SCATTERED STRONG-SEVERE THUNDERSTORMS WILL PROPAGATE
ACROSS THE CENTRAL HIGH PLAINS OVER THE NEXT SEVERAL HOURS. WIND AND
HAIL CONTINUE TO BE A THREAT.
DISCUSSION...SCATTERED THUNDERSTORMS ARE GRADUALLY COALESCING ACROSS
THE CENTRAL HIGH PLAINS OF NORTHWESTERN NE/EXTREME SOUTHEAST WY.
THIS ACTIVITY HAS NOT YET DEVELOPED A SIGNIFICANT COLD POOL, BUT
FURTHER PRECIP EXPANSION IS POSSIBLE AS THE NORTHERN PLAINS UPPER
TROUGH APPEARS TO BE INFLUENCING THIS ACTIVITY. AS NORTHWESTERLY
MID-LEVEL FLOW STRENGTHENS ACROSS WESTERN NE, ONGOING CONVECTION
SHOULD CONTINUE TO PROPAGATE SOUTHEAST. LATEST SHORT-RANGE MODEL
GUIDANCE, INCLUDING MOST HREF MEMBERS, SUGGEST UPSCALE GROWTH INTO
THE EARLY-MORNING HOURS, AND AN MCS SHOULD EMERGE. A NEW SEVERE
THUNDERSTORM WATCH MAY BE NEEDED DOWNSTREAM TO ACCOUNT FOR THIS
SCENARIO.
