Strong words from the Storm Prediction Center on Monday's outlook: "A serious outbreak of destructive, tornadic supercells is likely over parts of this region this afternoon into evening, especially in the high- and moderate-risk areas. Given the expected fast storm motions, especially mid-afternoon into evening, a few of the best-organized supercells may reach an equilibrium with their already very favorable mesoscale environments long enough to sustain wide, long-track tornadoes."
Tulsa Public Schools and Catoosa Public Schools are closed Monday. Tulsa City-County Library branches will close at noon Monday. Collinsville High School postponed its graduation scheduled for Monday evening. Tinker Air Force Base has implemented liberal leave for those on the base, and a spokesman said aircraft were moved to other bases over the weekend.

(8 a.m. Monday): In an outlook issued Monday morning, the National Weather Service stated a "serious outbreak of destructive, tornadic supercells is likely" across the southern plains, including much of Oklahoma and parts of Texas throughout the day and into the overnight hours.
Forecasters have the Tulsa area in a "moderate" risk categories for severe weather, with a rarely used "high" risk area stretching from the Interstate 44 corridor to roughly Snyder, Texas. A tornado risk exists across an arc from west Texas to the Oklahoma-Missouri-Arkansas border, but the "high" risk area carries greater chances for violent, long-track tornadoes.
In an outlook issued Monday morning, the National Weather Service stated a tornado outbreak is likely across the southern plains, including much of Oklahoma and parts of Texas throughout the day and into the overnight hours.
After several days of warning that Monday's forecast had the potential for a significant event, forecasters now say those fears could be realized as early as lunchtime across eastern and central Oklahoma.
Forecasters have the Tulsa and Oklahoma City metro areas in "moderate" risk categories for severe weather, with a rarely used "high" risk area stretching from west Oklahoma City to roughly Snyder, Texas. A tornado risk exists across an arc from west Texas to the Oklahoma-Missouri-Arkansas border, but the "high" risk area carries greater chances for violent, long-track tornadoes.
Initial modeling as of early Monday reportedly has a first round of storms in both the Texas panhandle and across western and central Oklahoma as a warm front moves north across the state. These storms will initially produce large hail, but any cell that matures could produce a tornado. As they move northeastward, they will not only lose their associated tornado risk but also clear the area, allowing for a second round of storms forming in southwest Oklahoma and the Interstate 27 corridor in Texas.
