DISCUSSION...
SFC LOW CURRENTLY OVER CENTRAL KS WILL TRACK INTO THE MID MISSISSIPPI
VALLEY TODAY WITH BREEZY W-NW WINDS PREVAILING ACROSS THE LOCAL
AREA. CURRENT PRECIP ACROSS NW AR WILL CONTINUE EASTWARD LEAVING
THE FORECAST AREA DRY AFTER SUNRISE. WRAP AROUND CLOUDINESS WILL
SPREAD INTO NORTHERN AREAS DURING THE DAY WITH ISOLATED SHOWERS
POSSIBLE THIS AFTERNOON ACROSS FAR NE OK / FAR NW AR. SFC HIGH
PRESSURE WILL CONTINUE TO BUILD INTO THE REGION OVERNIGHT WITH
NOTICEABLY COOLER TEMPERATURES ON TUESDAY WITH WINDS GRADUALLY DIMINISHING.

THE NEXT WAVE TO INFLUENCE THE REGION PUSHES INTO THE WESTERN HIGH
PLAINS ON WEDNESDAY WITH LIGHT RAIN EXPANDING ACROSS THE AREA IN
ITS ADVANCE. AN INCREASING TREND IN THE DATA IS THAT THE HEAVIER
PRECIP WILL BE FAVORED SOUTH OF INTERSTATE 40 WITH NOTICEABLY
LIGHTER AMTS FURTHER NORTH. INCREASING CLOUD COVER AND PRECIP WILL
MAINTAIN THE COOL TEMPS.

TROUGHING REMAINS TO OUR WEST THURSDAY BEFORE ANOTHER WAVE SHIFTS
ACROSS THE AREA FRIDAY INTO SATURDAY. THIS WILL MAINTAIN PRECIP
CHANCES UNTIL THE TROUGH AXIS PASSES. THERE REMAINS CONSIDERABLE
SPREAD IN THE DATA REGARDING THE TRACK OF THIS SYSTEM...HOWEVER
TEMP PROFILES CURRENTLY SUPPORT ALL RAIN FOR THE MAJORITY OF THE
EVENT DESPITE THE VARIOUS TRACKS OFFERED.
