.DISCUSSION...
SFC ANALYSIS AT 3 PM SHOWED PRE-FRONTAL TROUGH EXTENDING FROM
ROUGHLY KSTJ-KLBL WITH ACTUAL COLD FRONT LAGGING FROM EXTREME NW
MISSOURI INTO SE COLORADO. FRONT WILL GRADUALLY DROP SOUTH THIS
EVENING AND WILL LIKELY BE APPROACHING OK/KS BORDER BY MIDNIGHT OR
EVEN LATER. GIVEN WEAK CONVERGENCE ALONG BOUNDARY...WEAK LAPSE
RATES AHEAD OF THE FRONT AND UPPER LEVEL SUPPORT WELL TO THE
NORTHEAST...NOT EXPECTING MUCH MORE THAN SCATTERED CONVECTION
LATE TONIGHT. THUNDERSTORM CHANCES WILL TREND SOUTH DURING THE DAY
SUNDAY...ALTHOUGH THERE WILL LIKELY BE A LULL IN THE ACTIVITY
DURING THE MORNING OR EARLY AFTERNOON BEFORE REDEVELOPMENT
COMMENCES SOUTH OF I-40 IN THE AFTERNOON...AGAIN WITH SCATTERED
COVERAGE AT BEST.

FRONT WILL USHER IN MUCH LOWER DEW POINTS LEADING TO STRETCH OF
PLEASANT TEMPS AND MAINLY DRY WEATHER. WEAK UPPER LOW PASSING TO OUR
NORTHWEST TUE/WED MAY INCH CLOSE ENOUGH TO BRING A CHANCE OF
SHOWERS TO FAR NORTHWEST AREAS. HOWEVER WITH THE SFC PATTERN
FEATURING A BROAD AREA OF HIGH PRESSURE EXTENDING ALL THE WAY FROM
NEW ENGLAND TO OK/AR...DRY AND STABLE REGIME WILL PERSIST THROUGH
THE REMAINDER OF THE EXTENDED PERIOD.
