NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
202 AM EDT SUN JUL 12 2026
AREAS AFFECTED...CENTRAL AND EASTERN OK
CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE
VALID 120602Z - 121200Z
SUMMARY...LOCALIZED AREAS OF FLASH FLOODING WILL BE POSSIBLE
THROUGH EARLY THIS MORNING FROM AREAS OF HEAVY SHOWERS AND
THUNDERSTORMS.
DISCUSSION...THE LATEST GOES-E IR SATELLITE IMAGERY ALONG WITH
RADAR SHOWS AN AXIS OF HEAVY SHOWERS AND THUNDERSTORMS DROPPING
GRADUALLY DOWN TO THE SOUTH-SOUTHWEST ACROSS AREAS OF CENTRAL AND
EASTERN OK. AN OUTFLOW BOUNDARY ASSOCIATED WITH THIS ACTIVITY
CONTINUES TO INTERACT WITH A MOIST AND UNSTABLE AIRMASS POOLED UP
ACROSS THE BROADER RED RIVER VALLEY, AND THIS WILL SUPPORT
ADDITIONAL AREAS OF CONVECTION PERSISTING AT LEAST THROUGH THE
EARLY MORNING HOURS.
MLCAPE VALUES NEAR 1500 J/KG AND PWS OF 1.75+ INCHES WILL MAINTAIN
A THREAT FOR HIGH RAINFALL RATES REACHING 1.5 TO 2.5 INCHES/HOUR.
THE SLOW CELL-MOTIONS NOTED IN RADAR IMAGERY SUGGESTS SOME
ADDITIONAL SHORT-TERM RAINFALL TOTALS COULD REACH UP TO 3 TO 4
INCHES, AND THIS IS SUPPORTED BY A CONSENSUS OF THE LATEST HIRES
CAMS.
THESE ADDITIONAL RAINS OVERNIGHT AND THROUGH EARLY THIS MORNING
MAY POSE AN ADDITIONAL LOCALIZED THREAT FOR FLASH FLOODING.
GENERALLY THE MORE URBANIZED LOCATIONS WILL BE AT GREATEST RISK
FOR SEEING ANY IMPACTS SINCE FFG VALUES ACROSS THE REGION ARE ON
THE HIGH SIDE.
