AREA FORECAST DISCUSSION

...UPDATE...

.DISCUSSION...
A LONGWAVE TROF AXIS WAS CURRENTLY SHIFTING EASTWARD OVER
NORTHWEST ARKANSAS PER LATEST WATER VAPOR IMAGERY. ALONG AND
BEHIND THIS AXIS...LIGHT PRECIP IN THE FORM OF LIGHT DRIZZLE/LIGHT
RAIN CONTINUED TO BE OBSERVED ACROSS PORTIONS OF EASTERN OKLAHOMA
AND NORTHWEST ARKANSAS. A FEW LOCATIONS ACROSS FAR NORTHWEST
ARKANSAS HAVE REPORTED SOME LIGHT SNOW MIXING WITHIN THE LIGHT
RAIN...ESPECIALLY OVER THE HIGHER TERRAIN LOCATIONS. AN OVERCAST
LOW LEVEL CLOUD DECKS HELD SURFACE TEMPERATURES DURING THE NIGHT
AND EARLY THIS MORNING IN THE MID/UPPER 30S OVER MOST
LOCATIONS...WHICH ALLOWED PRECIP TO REMAIN MAINLY LIQUID ACROSS
EASTERN OKLAHOMA.

PRECIP CHANCES WILL REMAIN POSSIBLE OVER FAR EASTERN OKLAHOMA INTO
NORTHWEST ARKANSAS THROUGH THE LATE MORNING HOURS AND SHOULD EXIT
NORTHWEST ARKANSAS BY MID AFTERNOON WITH THE DEPARTING LONGWAVE
TROF. TEMPS OVER THESE LOCATIONS SHOULD ALSO REMAIN IN THE
MID/UPPER 30S FOR MUCH OF THE DAY...WHICH COULD ALLOW FOR A
CONTINUED CHANCE OF SOME LIGHT SNOW MIXING IN WITH LIGHT RAIN.
WILL KEEP A MENTION OF SNOW ACCUMULATION...HOWEVER...WILL LOWER
AMOUNTS A BIT TO LESS THAN A QUARTER OF AN INCH OVER FAR NORTHWEST
ARKANSAS...WITH TRACE AMOUNTS TO AROUND A TENTH OF INCH BEING MORE
POSSIBLE.

ACROSS THE REST OF THE CWA...SKIES ARE EXPECTED TO CLEAR OUT THIS
AFTERNOON FROM WEST TO EAST ACROSS EASTERN OKLAHOMA AND THIS
EVENING OVER NORTHWEST ARKANSAS. THE CLEARING LINE AS OF MID
MORNING WAS LOCATED OVER CENTRAL OKLAHOMA. THIS WILL HELP
AFTERNOON TEMPS GET UP INTO THE 40S FOR EASTERN OKLAHOMA...WHILE
TEMPS OVER NORTHWEST ARKANSAS SHOULD NOT WARM MUCH. MORNING UPDATE
WILL BE TO ADJUST POPS/WX/SNOW AMOUNTS BASED ON THE MENTIONED
ABOVE...WHILE TWEAKING AFTERNOON SKY/TEMP GRIDS BASED ON LATEST
TRENDS.
