GALION — Old man winter won’t hold back in the northern Plains this season with shots of brutally cold air predicted to slice through the region.
Developing snowpack in early December may contribute to even colder weather. Temperatures will plummet as the season goes on, averaging 6 to 9 degrees lower overall than last winter.
“…There are going to be some nights, especially if there’s snowcover in the heart of winter, that could get down to 20 or 30 below, especially in parts of Minnesota like International Falls and Duluth and parts of the Dakotas,” Pastelok said.
Cold air will also remain entrenched across the Midwest after arriving in late November. Coupled with warmer waters over the Great Lakes, an early start to lake-effect season is in store.
“I do feel we’re going to kick this season off pretty quick, especially the western lakes. But I think even the eastern lakes will get involved and it will extend all the way out to January,” he said.
Freeze could harm southern citrus crops
Winter will slowly creep into the Southeast this season, as very mild air hangs on throughout the month of December.
However, the new year will usher in a pattern change as a sudden burst of cold air penetrates the region.
“I am afraid that we have a shot at seeing a damaging freeze in central Florida in mid- to late January this year,” Pastelok said.
The chill could spell disaster for the area’s citrus farmers.
Cold air will once again retreat following January and the threat is predicted to shift to severe weather.
“Places like Atlanta, Chattanooga, even up into Roanoke, they could have some severe weather,” Pastelok said. “But if the storm track is a little farther east, then you’re looking more like Tallahassee to Savannah and, maybe, Charleston.”
Early storms to blast Northwest, northern California
Winter will waste no time in the northwestern U.S. and northern California, as the season kicks off with rain and winter storms.
“They’re going to start out pretty wet, especially from northern California into the Northwest coast,” Pastelok said. “I think that, right off the bat in December, we start to see the snow piling up in the mountains.”
November and December will see the most action, before high pressure builds in and stormy weather eases back in late January and February.
Dry, warm season in store for Southern California, Southwest
While moisture aims for the Northwest, warm and dry conditions will span much of the season for central and Southern California and the Southwest.
“December is [looking] very warm [in the Southwest] and I think we could break some record high temperatures,” Pastelok said.
A few cold shots will hit areas like Phoenix and Flagstaff, Arizona, in January, but the warm weather will quickly rebound.
For Southern California, the pattern will exacerbate ongoing drought conditions.
“We’re in a pattern that doesn’t really show a lot of rain coming toward Southern California, so I don’t expect too much relief,” Pastelok said.
What precipitation does fall in California will aim primarily for the north, though it will fail to have the significance of last January when the region was hammered by heavy rain and snow.
“I do think in the early part of the season we’re looking good anywhere from San Francisco, Sacramento and into the mountains,” he said.
“…If we can get some snowpack built up in the north, we can fill up these reservoirs going into spring and summer.”
Winter to get late start across southern Plains, Gulf Coast
Fall-like weather will linger into the winter season across the southern Plains and Gulf Coast, but a change will loom on the horizon.
“A turnaround could come into late December and January as chillier air masses work down from the north,” Pastelok said.
Though the milder weather will retreat, dryness will stick around, becoming a major theme of the season.
“The area of the country that may miss out on big [snow] storms this year may be Dallas and Little Rock,” he said. However, a few disruptive ice events are not out of the question.
