Cool, dry outlook for first part of November

Cool and dry weather is expected over much of the Midwest the first two weeks of November.

Iowa Department of Agriculture and Land Stewardship State Climatologist Justin Glisan says an active storm track is making way for an equal to better chance of below normal temperatures coupled with a dryer pattern.

“Especially in the precipitation field, we see that equal chance spanning from Indiana all the way over into the Dakotas and Minnesota.”

He tells Brownfield there is a slight development towards a classic La Nina signature.

“And we have transitioned into what’s called a La Nina advisory, and that La Nina means a cold sea surface temperature anomaly in the tropical Pacific that shifts thunderstorm activity further west in the Pacific Basin.”

Gilsan says this elevates the probability for wetter conditions later in the month across the Ohio Valley into the Great Lakes over to Montana and the Pacific Northwest, with dryer than average chances across the southern half of the U.S.
