| View from my airplane window the other day as we descended into Sioux Falls, Vermont last Thursday. It's awfully hot out here on the Great Plains for late September! |
It was 92 degrees out here in Yankton Sunday, so it was a truly summer day. It wasn't very humid, so the heat was manageable. Forecasts call for temperatures of near 90 degrees in Yankton today and tomorrow.
This all will make my impending return to Vermont feel even chillier than it will be. And it will be chilly enough, as many Vermont towns will stay below 60 degrees Wednesday and Thursday.
Normal temperatures out here in Yankton are only a little warmer this time of year than in Vermont. But extremes are wider. Daily record highs are hotter than in Vermont, and daily record lows are lower.
The bottom line is, if you think Vermont weather bounces around a lot, try the Northern Plains.
Back in Vermont, I'm pretty sure there won't be any true summer weather again until next, well, summer. Or maybe late spring. That hot air in the Plains is not heading toward Vermont. Instead, an upper level low pressure system will direct Canadian air over us for the next few days.
It's a dry pattern, too, which is too bad because northern areas of Vermont still need the rain. A cold front and weather disturbance today will produce a tenth to three tenths of an inch of rain today, which is really not a whole lot.
Very light, scattered showers could roam around Wednesday and Thursday in the chilly air but won't amount to much.
So far at least, frost during this cool spell looks like it will be limited to the normal cold spots. But keep watching the forecast daily. If any part of Vermont ends up getting several overnight hours of clear skies and light winds during this cool spell, frost could be more widespread.
Sure, there will be warm days ahead as we're still early in autumn. But sustained summer weather is gone until next year.
