Severe storms possible Monday night

(TULSA, Okla.) A warming trend will continue over the next several days. A few light showers will be possible from southeast Oklahoma into northwest Arkansas Sunday night, but no significant rainfall is expected. Thunderstorm chances will increase across eastern Oklahoma by Monday evening, with the threat expanding into western Arkansas during the night. Forecast instability and wind shear are supportive of at least a limited risk of severe weather, most likely in the form of large hail with elevated storms across northeast Oklahoma. Farther south the overall storm coverage remains uncertain at this time. Some threat of heavy rainfall will also exist across northeast Oklahoma and northwest Arkansas, with some localized flooding potential due to saturated soil conditions. Showers and storms will end early Tuesday, with much above normal temperatures then likely to prevail for the rest of the work week. A frontal boundary will stall near the Kansas/Oklahoma border Thursday, and remain in that vicinity through Friday before getting a push to the south. Shower and thunderstorm chances will increase Thursday night through Friday night, with some potential for severe storms once again. Drier weather with seasonable temperatures will return for next weekend. Monday Cloudy, with a high near 67. Calm wind becoming southeast around 5 mph in the afternoon.
