The jet stream pattern which has provided us with slightly cooler summer and has chilled the northeastern U.S. looks as if it will be shifting more to the central U.S. next week. This means we will continue to see below normal temperatures and perhaps wetter conditions.
There is some evidence in the computer weather models that the shift will cause a front to stall somewhere in the central Great Plains during this period. This usually brings enhanced rainfall to areas along and north of the front. Since summer is a time of deeper moisture (high dew points) to the south of cool fronts, this can mean excessive rain is possible in this zone.

The 6-10 day outlooks issued by the Climate Prediction Center show the cooler temperature departure area in blue and the above average precipitation area in green. The current thinking is to set this front up more to our south be we in the Ozarks should be watching this for possible adjustment.
The whole stalled front episode will likely be followed by another cool shot which will send our lows into the fifties once again with highs only in the seventies.
