Quiet conditions will continue into tonight, with mainly clear skies overnight. Winds will be light and temperatures will cool down into the low 50s in most areas, with perhaps a few locations dipping down into the upper 40s across the north. With light winds, cool temperatures and clear skies, a bit of fog is not out of the question. However, if any fog does form, it is likely to remain patchy.
On Monday, the next storm system will rapidly begin to organize across the western high plains with a major severe weather outbreak looking likely for parts of Oklahoma and Kansas. In the Ozarks, we'll start with sun, and southeasterly breezes will start to transport in more humid air. With a bit more warmth, and building low level moisture, the atmosphere will become more unstable by late in the day. Several models show showers and thunderstorms moving into the area by late Monday afternoon and evening. Some of these storms may be severe. More strong to severe storms are possible overnight Monday.
There may be a brief lull in storm activity early Tuesday, before the next round of storms forms Tuesday afternoon and evening. Right now, it looks like we will see a squall line developing with damaging winds the primary severe weather threat along with heavy rainfall.
Once this system moves through, a large ridge of high pressure will build over the southeast U.S. and then spread north into Missouri. This will bring a summer-like pattern to the region with highs from Wednesday on in the mid to upper 80s and increasing humidity. Warm and muggy conditions will continue right into next weekend. A few storms will be possible Friday, Saturday and Sunday, with the best chance for storms showing up on Saturday the way it looks.
