Area forecast discussion, Aug 9, 3:33 AM CDT, 2 hours 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
333 AM CDT FRI AUG 9 2013

.DISCUSSION...
A SURFACE FRONTAL BOUNDARY CURRENTLY LIES EAST WEST ACROSS CHOCTAW
COUNTY WITH A LARGE AREA OF PRECIPITATION NORTH OF THIS BOUNDARY
ACROSS MOST OF EASTERN OKLAHOMA. THE HIGHEST RAINFALL TOTALS WITH
THIS ACTIVITY HAVE BEEN IN THE RANGE OF 1.5 TO 2 INCHES. THE AREA OF
HEAVIEST RAINFALL IS EXPECTED TO CONTINUE TO TRACK NORTHEASTWARD
ACROSS THE FORECAST AREA THROUGH THE DAY TODAY. HAVE EXTENDED THE
CURRENT FLASH FLOOD WATCH TO RUN THROUGH THIS AFTERNOON IN ITS
CURRENT CONFIGURATION.

MORE OF THE SAME MCS ACTIVITY IS EXPECTED TO BE GENERATED ACROSS
THE AREA AGAIN TONIGHT. MODELS DO NOT MOVE THE SURFACE FRONT MUCH
OVER THE NEXT 24 HOURS. PRECIPITABLE WATER ACROSS THE REGION IS
PROGGED TO REMAIN NEARLY 2 INCHES. GFS AND NAM BOTH GENERATE LIFT
ACROSS EASTERN OKLAHOMA AND NORTHWEST ARKANSAS FRIDAY NIGHT IN THE
SAME GENERAL AREA AS THE CURRENT ACTIVITY. QPF AMOUNTS TONIGHT ARE
ACTUALLY A BIT LOWER... SO AT THIS TIME WILL NOT ISSUE ANY
ADDITIONAL FLOOD PRODUCTS.

THE PATTERN FINALLY BEGINS TO SHIFT EAST BY SUNDAY... WITH RAIN
CHANCES LESSENING. THIS MAY BE ONLY A BRIEF RESPITE HOWEVER... AS
NORTHWEST UPPER FLOW BECOMES ESTABLISHED OVER THE SOUTHERN PLAINS BY
EARLY NEXT WEEK. THIS PATTERN WILL AGAIN BE FAVORABLE FOR NOCTURNAL
MCS ACTIVITY.

A CONTINUED MOIST ENVIRONMENT WILL KEEP OVERNIGHT LOW TEMPERATURES
NEAR SEASONAL AVERAGES OVER THE NEXT WEEK OR SO... WHILE CONTINUED
CLOUDS AND PRECIPITATION WILL KEEP DAILY MAXIMUM TEMPERATURES BELOW
AVERAGE.
