DISCUSSION...
THIS IS DEFINITELY A QUIETER FORECAST PERIOD THAN HAS BEEN THE CASE
IN RECENT WEEKS. THROUGH AT LEAST EARLY NEXT WEEK...A RIDGE OF HIGH
PRESSURE IS EXPECTED TO REMAIN ANCHORED OVER AZ/NM AND EXTENDING INTO
HIGH PLAINS. A SHORTWAVE TROUGH CURRENTLY OVER ARIZONA TODAY WILL
ROTATE AROUND THE RIDGE AND HELP TO BRING A WEAK COLD FRONT THROUGH
THE PANHANDLES LATE THURSDAY NIGHT INTO FRIDAY MORNING. ENHANCED LIFT
WITH THE SYSTEM...AS WELL AS SURFACE CONVERGENCE ALONG THE
FRONT...COULD HELP PRODUCE SHOWERS AND THUNDERSTORMS ACROSS THE
PANHANDLES AROUND THIS TIME. BEST CONFIDENCE IS AROUND THE TIME OF
FRONTAL PASSAGE...WITH 20 TO 50 POPS FOR THURSDAY AND FRIDAY PERIODS.

THE RIDGE THEN BUILDS BACK OVERHEAD AS THE SHORTWAVE CONTINUES
EASTWARD. HAVE KEPT THE REST OF THE FORECAST DRY...AS BEST MID-LEVEL
MOISTURE LOOKS TO REMAIN OVER NEW MEXICO THROUGH EARLY IN THE WEEK.
COULD SEE SLIGHT CHANCES FOR RAIN IN THE NORTHWESTERN PARTS OF THE
FORECAST AREA SUNDAY THROUGH TUESDAY DEPENDING ON WHERE RIDGE SETS UP
EXACTLY. TEMPERATURES MOSTLY NEAR TO JUST A FEW DEGREES ABOVE NORMAL
THROUGH THE PERIOD.
