THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 275
CONTINUES.

SUMMARY...ISOLATED SEVERE THUNDERSTORMS WILL CONTINUE ACROSS WW275.

DISCUSSION...SLOW MOVING MCS APPEARS TO BE DEVELOPING ACROSS THE SRN
HIGH PLAINS/ROCKIES THIS EVENING. ALONG THE SWRN FLANK OF THIS
EXPANDING CONVECTIVE COMPLEX DEEP LAYER SHEAR/INSTABILITY IS A BIT
STRONGER ACROSS CNTRL NM. AS A RESULT...ISOLATED SUPERCELLS HAVE
EVOLVED ACROSS THE WRN HALF OF WW275 AND THESE MORE DISCRETE
STRUCTURES HAVE PRODUCED LARGE HAIL AT TIMES AS THEY MOVE SEWD AT
ROUGHLY 20-25KT. GIVEN THE ORIENTATION OF THE INSTABILITY AXIS IT
APPEARS THE GREATEST SEVERE THREAT WILL REMAIN CONCENTRATED NEAR THE
HIGHER TERRAIN FOR THE NEXT SEVERAL HOURS.
