A large swing in the jet stream will finally bring some wet weather to fire scorched areas of California this week. The persistent dry conditions in the west over the last several months has led to the largest loss of life of any natural disaster in the state in more than a hundred years… and that toll is still rising. The only thing that will stop the kindling from continuing to go up in flames is moisture… and it’s finally on the way.
The river of air at the top levels of the atmosphere that’s effectively the steering current for storms, known as the jet stream, is expected to dive southward into California midweek and could bring a few inches of rain to the mountains, with up to an inch of rain for some of the valleys. While this won’t cure the current desperately dry situation, it may prevent future fires from popping up for at least a couple weeks. Not to mention, help firefighters squelch the current blazes still rolling statewide.
It’s this same pattern shift that will warm temperatures back above average in the Upper Midwest, including Minnesota, for at least a couple of days over the long Thanksgiving weekend. But those storms rolling on shore in the west will have to end up somewhere, so we’ll have to watch out for some rain and snow potentially heading through the state over the weekend as well.
