It appears the real severe weather season in Oklahoma will get going beginning this Saturday. The models over the past couple of days have been hinting at a pattern that will result in a prolonged period of thunderstorms with associated severe weather potential and heavy rain/flooding potential. I can see a possible scenario of severe weather in the state every day from Saturday through the end of next week. Beyond the end of next week it's vague, but the pattern could continue beyond that.
This Saturday evening the severe weather threat will be over western Oklahoma, with the greatest threat over NW Oklahoma. Wind shear profiles look ideal for supercells: from top to bottom (surface) the winds go from W, to SW, to S, to SSE at ground-level. I imagine there will be 1-3 isolated supercells in western Oklahoma Saturday evening that will have the threat of producing tornadoes. Any threat to OKC appears slight at this time and would more than likely be between 10PM and 2AM.
Depending on where the cold front sets up Sunday and the rest of next week (which is highly dependent on the amount of rain that occurs with/behind the front), more severe weather and isolated tornadoes will be possible. One day I see on the horizon that could have an enhanced threat of tornadoes would be Wednesday, but that is not set in stone by any means.
Bottom line is this: Late April and Early May are primetime for severe weather in Oklahoma. Some years we are lacking in storms moving through during this peak season, but it appears as though a stormy pattern will coincide with peak severe weather season this year. Just stay weather aware over the next couple of weeks. If you don't own one, I highly recommend purchasing a programmable NOAA weather radio. The programmable radios are more expensive, but you can set them to just go off for certain counties and certain warnings (Tornado, Severe Thunderstorm, Flood, etc.) The cheaper ones give you peace of mind as well, but you can only program by county, not by type of warning.
More updates to come in the coming days!
