Reversion to the mean in the temperature charts with cool anomalies confined to the Pac NW and near the upper Great Lakes. Otherwise temperatures are forecast to be at seasonal averages over nearly all of the lower 48; maybe slightly cool over the lower MS valley and slightly warmer over the Atlantic seaboard. At this point only relatively light precipitation is expected the week after next over the Mississippi basin and midwest; the west and Texas look quite dry and the Atlantic seaboard rather wet.

This week quite heavy rain is likely over NW North Dakota and Montana with locally heavy thunderstorm precipitation likely over much of the central and northern Mississippi basin, the Missouri river basin, and over the Southeastern states. The eastern half of the country (except for New England) should expect a significant warming trend this week as a continental blocking pattern sets up and the jet stream shifts north into Canada. A large ridge will build early in the week over the east and later over the west, split by an area of low pressure moving through the NW early this week that becomes trapped between the two ridges over Missouri-Kansas by the end of the week. All of the Gulf States and Florida, plus OK and Kansas should expect well above normal temperatures this week, with some cooling over KS and OK as the low pressure approaches wednesday.
