A June full of extreme weather

We’re heading toward the end of June and North Idaho has yet to report a 90-degree day. However, at the Spokane International Airport, a high of 90 degrees was hit June 22. The high on that date in Coeur d’Alene was 86 degrees. Other stations in the region reported highs in the mid-to-upper 80s on June 22, but there was a 90-degree high at Worley.
With astronomical summer beginning last week, it doesn’t appear that we’re going to have a spell of very hot weather across the Inland Northwest through at least early July. However, Cliff and I do believe that we’ll have a period of about four to six weeks of very warm to hot weather with below-normal precipitation beginning around the middle of July. By late August and September, precipitation totals should climb to near to above-normal levels in our region as we should start to see more of an influence from the cooling of sea-surface temperatures along the Equator.
Our weather patterns seem to be in a transition with the sudden cooling of sea-surface temperatures in the waters of the south-central Pacific Ocean. Many computer forecast models and forecasters are stating that we have a good chance of seeing a new La Niña, the cooler-than-normal sea-surface temperature event, form late this year. The latest information does show a small stretch of cooler-than-normal waters along the equatorial regions that is pointing to a new La Niña. As I mentioned in previous articles, if a phenomenon does form, it would be the fourth one in five years, which is very rare. A new La Niña would also mean an increased chance of above-normal snowfalls across the Inland Northwest and much of the northern U.S. during the next winter season.
