Heavy rainfall, severe weather expected next week

(TULSA, Okla.) A period of unsettled weather will prevail for much of the upcoming week as a surface cold front approaches with an upper system. While there will be severe weather potential in the Monday to Wednesday period, an increased potential for heavy rainfall and flash flooding will likely exist, especially Tuesday and Wednesday as the front moves slowly across the area. The next cold front is forecast to move into north-central Oklahoma on Monday. Thunderstorms should increase in coverage Monday night, potentially impacting portions of northeast Oklahoma. There remains some uncertainties regarding the southward progression of cold front on Tuesday which will have significant impact on main thunderstorm timing. The severe weather threat will likely increase with all modes of severe weather possible, including the threat for heavy rainfall/flash flooding. The front is expected to briefly stall over the area on Wednesday and with a very moist/unstable air-mass in place along/south of boundary, severe weather/heavy rainfall threat will persist with the potential for training thunderstorms. Rain is expected to taper off Thursday as cooler air moves in behind the front. Dry mild conditions are expected behind the cold front Friday into the early part of the weekend as surface ridge builds into the region.
