Cool Summer for Much of the U.S.


The Ozarks were not alone in having a cool summer. The states in blue all recorded below normal conditions and the numbers indicate the ranking of the state on its overall coolest summer list. Missouri ended up 12th and Arkansas was 23rd.

A persistent trough of low pressure aloft not only kept a constant supply of cool air flowing south from Canada but also kept clouds in the picture through much of the Great Lakes and New England.

We had ranked cool months in July and August in the Ozarks. A heat wave in late June and a brief burst of hot temperatures in early August are the only signs of summer we had in the region.

Low Pressure Backing Up


A weak and isolated low which was previously thought to be moving eastward by later in the week is now forecast to stall a bit more and probably track westward, passing south of the Ozarks, between now and Saturday.

The upshot of this is to keep rain chances going as long as this feature is close by. The 1-3 day rainfall forecast through Friday from the HPC is included, showing areas of western Arkansas forecast to pick up in excess of 4" as a result of this feature.

In the Ozarks, the rain totals ramp up quickly moving southward. A few inches of rain are conceivable in portions of Arkansas.

Bands of showers rotating around this feature will be capabile of producing locally heavy downpours in isolated sections of Missouri too.

It appears as if a weekend cool front will finally "kick" the rain system out of here at that time.
