Upper low, currently over southeast New Mexico will lift northeast into Oklahoma today.
Scattered showers/thunderstorms have begun to develop over central Oklahoma early this morning. Latest model runs indicate thunderstorm activity will likely lift into northeast/east-central Oklahoma this morning. Potential amounts ahead of the upper system forecast to be near 2 inches with the potential for heavy rainfall in the stronger storms.
Although widespread flooding is not expected, localized flash flooding appears likely given the slow
storm motions expected/high rain rates. In addition, portions of southeast Oklahoma/west-central Arkansas have greatly reduced flash flood guidance from Wednesday`s storms.
A flash flood watch will be issued for the entire area through tonight. Localized 3 to 4-inch rainfall amounts will be possible, although most locations will more than likely see 1/2 to one inch.
Upper low will move east into Arkansas during the day Friday. Low-level moisture will persist on the back side of the system and with surface heating, additional showers/scattered thunderstorms will
likely redevelop over eastern Oklahoma/northwest Arkansas.
Precipitation chances will begin to taper off from west to east Friday night into Saturday. Drier air-mass will filter into the region Sunday night into Monday with dry/mild conditions through
midweek as high pressure builds into the central/southern plains.
