SHALLOW COLD FRONT HAS BEEN ERODING ON ITS LEADING EDGE AS
DAYTIME HEATING MODIFIES THE AIRMASS.  KMAF HAS BEEN FLIRTING
WITH W TO NW WINDS LAST SEVERAL HOURS.  FRONT APPEARS HUNG UP ON
THE WESTERN END AND AT 20Z STRETCHED FROM NORTH OF KCNM... TO
KMAF... TO NORTH OF KSJT.  COOLER AIR STILL LAGGED TO THE NORTH.
FRONT EXPECTED TO GET MOVING AGAIN TONIGHT AND PUSH THROUGH MOST OF
THE AREA BY MIDDAY TOMORROW.

STILL EXPECT WIDELY SCATTERED/SCATTERED LATE AFTERNOON THUNDERSTORMS
TO DEVELOP IN THE SOUTHEAST PART OF THE AREA AS THERE ARE SEVERAL
BOUNDARIES TO FOCUS DEVELOPMENT ON.  AS COOLER AIR HAS BEEN
RELUCTANT TO MOVE SOUTH... OVERNIGHT LOWS ARE A PROBLEM.  GUIDANCE
HAS BEEN TOO COOL... WILL STAY ABOVE.
