.DISCUSSION...
REINFORCING COLD FRONT WILL PUSH THROUGH THE REGION TODAY KEEPING
HIGHS WELL BELOW NORMAL...WITH SCATTERED SPRINKLES POSSIBLE ACROSS
FAR NE OK / FAR NW AR. WINDS WILL QUICKLY TURN SOUTHERLY TONIGHT
ACROSS E OK...HOWEVER A LONGER PERIOD OF LIGHT WINDS WILL ALLOW
TEMPS ACROSS FAR NW AR TO APPROACH FREEZING THOUGH UNCERTAINTY
EXISTS AS MID CLOUDS WILL ALSO BE INCREASING AHEAD OF THE NEXT
WAVE.

A GOOD WEST TO EAST GRADIENT IS EXPECTED FOR HIGHS ON SATURDAY AS
SFC HIGH QUICKLY SHIFTS EASTWARD. THE AMPLIFIED PATTERN WILL
MAINTAIN FREQUENT FRONTAL PASSAGES...WITH THE NEXT FRONT ARRIVING
DURING THE DAY ON SUNDAY BUT NOT BEFORE TEMPS WARM APPRECIABLY. IT
APPEARS A NARROW AXIS OF INSTABILITY WILL DEVELOP ALONG THE
FRONTAL BOUNDARY ACROSS SE OK INTO WESTERN AR BY SUNDAY EVENING.
SUBSTANTIAL INHIBITION WILL PRECEDE THE BOUNDARY...HOWEVER FRONTAL
FORCING IS LIKELY TO BE SUFFICIENT TO PRODUCE SCATTERED
THUNDERSTORMS SUNDAY EVENING.

THE PATTERN ALOFT BECOMES LESS AMPLIFIED DURING THE FIRST PART OF
THE WORK WEEK...AND THE SUNDAY FRONTAL BOUNDARY IS EXPECTED TO
STALL AND GRADUALLY LOSE DEFINITION BY TUESDAY BUT NOT BEFORE
REMAINING A FOCUS FOR AT LEAST A SLIGHT CHANCE OF PRECIP. BY MID
WEEK MOISTURE RETURN LOOKS TO INCREASE WITH A MINOR WAVE PASSING
SUPPORTING A CHANCE OF SHOWERS AND THUNDERSTORMS...WITH A STRONGER
WAVE MOVING INTO THE PLAINS BY LATE NEXT WEEK.
