5/20 - 11:20am CDT - Off to Western Oklahoma

After a not-as-good-as-we-thought-it-would-be day yesterday, we're off to Western Oklahoma in search of storms that will likely fire this afternoon behind an already ongoing line of storms in the central and eastern part of the state. Upper-level winds should be supportive of storms that could fire this afternoon, but we're still waiting for the atmosphere to recover behind the ongoing storms this morning. Short-range models indicate ample moisture with decent instability in the western part of the state. The dry line, which you can easily see in the dew point forecast image below, will provide a focus for storm formation as outflow boundaries from this morning's storms interact with it. This interaction will create lift to get storms going this afternoon. Temperatures aloft will still be a little cool for really good isolated storm development, but we'll take what we can get.
