A fitting start to autumn: forecaster says low temperatures, frost today could usher in harvest season | news

CADILLAC — Temperatures haven’t really felt autumn-like so far this September, but in an ironic twist, all that is expected to change today — the first day of the autumnal equinox.

Accuweather meteorologist Brandon Buckingham said while the summer months were slightly below normal overall — 2.1 below normal in June, 0.9 below July and 0.3 below August — September bucked that trend, with Temperatures that were 3 degrees above normal on Wednesday.

That unusual warmth is expected to be tempered today, when Buckingham said temperatures are expected to drop significantly, potentially producing the first frost of the season.

High temperatures are not expected to rise above 54 degrees during the day tomorrow, according to the National Weather Service, while low temperatures could drop to nearly 34 degrees at night.

“People may want to bring sensitive crops indoors,” said Buckingham, adding that the low temperatures could herald the harvest season for farmers in the area.

“It’s definitely going to feel like sweatshirt weather,” Buckingham said. “It’s going to have that raw October or November feel … like football season or salmon fishing weather.”

Temperatures are forecast to recover into the 60s on Friday, Saturday and Sunday, but Buckingham said the remaining days of September are likely to remain much colder than at the start of the month. Buckingham said they believe temperatures will follow a “roller coaster pattern” for the remainder of the month, with rapid spikes of 10 to 15 degrees above seasonal norms, followed by cold fronts bringing autumn-like conditions back to the area.

This is a typical type of pattern on the way to a La Nina winter that the U.S. has experienced for the past three winters in a row, Buckingham said. What that means for October and November is more of the same rapid swings in temperature; For example, while temperatures could soar back into the 70s on a few days in October, those highs are expected to collapse a day later as the cold front pulls through.

Temperatures are forecast to be 1 to 1.5 degrees above normal for October overall, while temperatures in November are forecast to be 1 to 2 degrees below normal. Temperatures for the first half of December are expected to be 1 to 2 degrees above normal.

Overall, the fluctuations in average temperatures should not be too extreme, resulting in an average time of year in many ways.

The extended fall forecast calls for lower-than-usual temperatures across the country, according to the Farmers’ Almanac. The cold will really kick in in the second half of November and continue through the rest of the year.

The Farmers’ Almanac also predicts above-average rainfall for much of the central part of the country, including the Great Lakes, the Ohio Valley and Midwest, and the Rockies and Great Plains.

Buckingham confirmed there are likely to be some opportunities for active weather in the form of showers and storms over the next few weeks, but he said it doesn’t look like snow will be early this year; It’s possible the first snow could arrive by October, but given historical norms, Buckingham said it’s more likely to show sometime in November.
