AREAS AFFECTED...KS/SE CO/NE NM/OK PANHANDLE/NRN TX PANHANDLE

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 191905Z - 192030Z

SCATTERED CONVECTION WILL CONTINUE DEVELOPING ALONG THE MTNS OF NE
NM AND FAR SERN CO. ADDITIONAL STORMS WILL STRENGTHEN OVER SWRN KS.
THE CONVECTION WILL HAVE THE POTENTIAL FOR ISOLATED LARGE HAIL
AND/OR DAMAGING WIND GUSTS. A WW MAY BECOME NECESSARY OVER THE NEXT
HOUR OR SO.

CONVECTION IS DEVELOPING IN NE NM/SE CO...NORTHEAST OF A SFC
LOW/CONVERGENCE ZONE EXTENDING DOWNSTREAM FROM UPPER IMPULSE MOVING
EWD ACROSS SRN CO/NRN NM. MODERATE INSTABILITY IS PRESENT ACROSS THE
REGION...WITH MLCAPE OF 1000 TO 1500 J/KG. OBJECTIVE ANALYSIS SHOWS
20 TO 25 KT OF DEEP LAYER SHEAR ACROSS THIS AREA SUGGESTING A
POTENTIAL FOR SEVERE MULTICELL STORMS WILL EXIST. STEEP LAPSE RATES
AROUND 9.0 C/KM WILL ENHANCE THE POTENTIAL FOR LARGE HAIL. A
DAMAGING WIND THREAT WILL ALSO EXIST CONSIDERING SFC DEWPOINTS ARE
IN THE 50S AND TEMPS HAVE REACHED THE 90 OVER MUCH OF THE AREA.
