...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF EASTERN NM...THE TX PANHANDLE...AND FAR WESTERN OK...
..SUMMARY
SOME STRONG TO LOCALLY SEVERE THUNDERSTORMS MAY OCCUR LATE THIS
AFTERNOON AND EVENING ACROSS THE SOUTHERN HIGH PLAINS.
..SYNOPSIS AND DISCUSSION
RECENT SURFACE ANALYSIS PLACES A PAIR OF HIGHS ACROSS THE CONUS, ONE
OVER SOUTHERN LOWER MI AND ANOTHER IN THE EASTERN ID/SOUTHWEST MT
VICINITY. A RESERVOIR OF LOW-LEVEL MOISTURE, CHARACTERIZED BY
DEWPOINTS ABOVE 60 DEG F, EXISTS BETWEEN THESE TWO FEATURES, FROM
THE SOUTHERN CONUS UP THROUGH THE PLAINS. THE LOW-LEVEL MOISTURE
WILL HELP FOSTER THUNDERSTORM DEVELOPMENT OVER MUCH OF THIS AREA,
WITH THE HIGHEST COVERAGE ANTICIPATED ALONG THE SURFACE TROUGHING
THAT EXTENDS FROM A PAIR OF SURFACE LOWS OVER THE CENTRAL PLAINS
INTO THE SOUTHERN HIGH PLAINS.
A BELT OF MODERATE WEST-NORTHWESTERLY FLOW ALOFT WILL EXTEND
EASTWARD FROM EASTERN CO/FAR NORTHEAST NM ACROSS KS INTO THE OZARKS.
SOUTHERN PERIPHERY OF THIS STRONGER FLOW WILL HELP SUPPORT MODERATE
EFFECTIVE BULK SHEAR ACROSS NORTHEAST NM AND THE TX PANHANDLE/TX
SOUTH PLAINS. DESPITE RESIDUAL CLOUD COVER AND POOR LAPSE RATES,
AMPLE LOW-LEVEL MOISTURE WILL HELP SUPPORT MODEST BUOYANCY ACROSS
THE REGION AS WELL. THE RESULTING ENVIRONMENTAL CONDITIONS MAY
RESULT IN A FEW STRONGER STORMS CAPABLE OF HAIL (LIKELY BELOW 1" IN
DIAMETER) AND/OR DAMAGING GUSTS.
