PAST CLIMATE MAPS
Last month I talked about the jet stream and how it was showing signs of repositioning itself further south. As it was, the bubble of hot and dry weather shifted more over the western United States, which brought cooler temperatures and a more active weather pattern over much of southern Minnesota and Iowa, resulting in an increase in rainfall. While the Twin Cities metro was left with much below normal rainfall.
I expect the jet stream to continue to bring us more active weather this month, especially the first half of the month, with rainfall totals averaging above normal. Temperatures this month are favored to average near normal as cooler Canadian air should make its presence felt.
A mix of sun and clouds are expected on the opening weekend of the month and into Labor Day, Sept 1-3. Accompanying the clouds will be passing showers, some of which could be locally heavy.
The sun, cloud and shower mix is favored to persist from Tuesday to Thursday, Sept. 4-6. Temperatures should cool.
Fair skies are expected on Friday and Saturday, Sept. 7-8.
The weather pattern is favored to stay active from Sunday to Saturday, Sept. 9-15. Look for more clouds than sun, with periods of soaking rains.
Sunshine is expected on Sunday, Sept. 16.
Prospects for showers are favored to taper off from Monday to Friday, Sept. 17-21. We'll see more sun, with shower activity becoming more scattered and isolated. Temperatures should warm.
Expect an increase in clouds and shower activity from Saturday to Tuesday, Sept. 22-25.
Sunny skies with little chance for rain are favored from Wednesday to Friday, Sept. 26-28. Temperatures should warm.
Look for passing clouds and showers on Saturday and Sunday, Sept. 29-30. Rainfall totals should be light.
