Stick A Fork In It, Garden Season Ends Tonight For Almost Everybody In Vermont

Agapanthus, an orange tree and other tropical plants on
my St. Albans, Vermont deck need to come in today
amid a freeze warning tonight. Other plants, like the 
half dead thing in the blue pot, will just be
abandoned to the frost, as the gardening 
season ends tonight amid subfreezing temperatures. 
 Well, this day had to come eventually. 

Your gardening days in Vermont are pretty much over. Until next spring. 

The biggest freeze of the season is on our doorstep, and from now on the only gardening the vast majority of us will be doing for the rest of the season is fall cleanup and storage.

 I've got some heavy lifting to do today as the orange tree, the hibiscus and several agapanthus plants in heavy pots that are on my deck all need to come indoors today. 

Who knew an autumn freeze would turn into a nice gym workout?

Anyway, it should get below freezing everywhere in Vermont except places right next to Lake Champlain. 

A freeze warning is in effect for the entire state, except the Northeast Kingdom, where the growing season ended with freezes earlier this autumn. And Grand Isle County, which is surrounded by the warm waters of Lake Champlain.

Even in Grand Isle County,  the National Weather Service is thinking about issuing a frost advisory for tonight, as temperatures might get close enough to the freezing mark to worry about frost. 

Most, but not all of us escaped a frost or freeze last night because clouds and wind kept up most of the night.  But you can tell the cold air is flooding in by looking at the mountains. 

As of 6 a.m., the summit of Mount Washington in New Hampshire was just 16 degrees, with a northwest wind gusting to 66 mph.  They're living up to their "world's worst weather" reputation.

The summit of Vermont's Mount Mansfield was down to 25 degrees at 6 a.m. Clouds might have left some rime ice at the summit. Skies cleared at dawn so you should take a peak at the Green Mountain summits. The tops might be white with ice.

Today will be bright and cool for your garden Emergency Frost Harvest. Sunshine won't help warm things up too much as actual temperatures struggle into the low 50s and a gusty northwest wind will add to the chill.

Tonight is a perfect setup for cold temperatures. The air will be dry, the wind will die down to calm, and the sky will stay clear. Which means you'll almost definitely be scraping ice off your windshield tomorrow morning. 

After our stretch of record October warmth, Montpelier could actually get to or at least close to a record low for the date tomorrow. Their record low for Friday is 24, and that's the expected low temperatures there. 

Any record lows won't be widespread, though. Most other towns and cities in and near Vermont should stay three to five degrees above record lows for tomorrow's date. 

Montpelier's forecast notwithstanding, this cold wave is not all that unusual for the first half of October. Though with climate change, it's been a few years since it's gotten this cold this early in the season. 

Another warmup is coming, starting Friday afternoon. But instead of record warmth, we're still looking at merely average temperatures. Heading through the weekend and into next week, that means lows within a few degrees of 40 and highs in the low 60s. 

Notice I didn't mention drought. There's too much to talk about there in this post, so look for an  update later this morning on that. Spoiler: The new U.S. Weekly Drought Report comes out this morning, and there has been some changes to the forecast for Sunday and Monday.
