September brings frost advisories and freeze warnings to Vermont

Our first cold weather warnings of the year are up for the North Country.

It’s early September, and as autumn begins to make inroads in the North Country and Northern New England, our first frost advisories and freeze warnings of the season have been posted by the National Weather Service Office in Burlington.  We’re under a frost advisory at our location with temperatures expected to be down near the freezing mark, but for some areas of the Adirondacks, temperatures are anticipated to get down into the upper 20s F, approaching near record lows for this date.  Further information can be found in the excerpt from the forecast discussion by the National Weather Service Office in Burlington below, with additional details at their site:

Widespread frost and freeze potential in Vermont

A map from the National Weather Service in Burlington showing the frost advisories and freeze warnings for Vermont and the surrounding areas on September 19th, 2012
Freeze Warnings and Frost Advisories are up throughout much of the state of Vermont tonight.

Parts of the Northeast have had bouts of sub-freezing temperatures since the end of August, but tonight looks like the first widespread occurrence of the season throughout Vermont.  We’ve got a frost advisory here in Washington County, but it sounds like some of the colder areas of the state up in the Northeast Kingdom could get down into the middle 20s F, and freeze warnings are in place.  It’s certainly time to cover up those gardens in the usual cold spots.

Another round of frost and freeze warnings for Vermont

The map of freeze warnings and frost advisories for October 5, 2011 from the National Weather Service Office in Burlington, Vermont
After our initial round of frosty weather back in mid September, more substantial freeze warnings and frost advisories are back for the start of October.

We’ve got another batch of cold air moving in over the next couple of days, so the National Weather Service Office in Burlington has put up freeze warnings throughout the area. Temperatures should be colder than last round with most areas in the 20s F, but since we’re into October now, that’s not all that surprising. For those areas like the Northeast Kingdom and the Adirondacks that don’t have warnings up, it’s because they aren’t needed; for those colder areas with early dates for the typical first frost, the growing season is considered to be over already. This is bad news for farmers in that area. Unfortunately, the weather cannot be changed. This will probably impact the crops of many farmers. To prevent this from happening next year, some farmers may want to take some extra precautions. Some may want to visit https://shrinkwrapcontainments.com/t-reinforcedblackout.aspx, for example, to purchase some light deprivation tarp. This is currently being used by full-time farmers in other areas who are trying to extend the growing season by creating artificial growing conditions. This tricks the crops, allowing them to continue growing for longer. Hopefully, this should help more farmers to have a successful growing season next year.

Some of the details from the National Weather Service have been added below:

Frost and Freeze alerts posted for Vermont

The frost and freeze warnings map from the National Weather Service Office in Burlington Vermont for September 16th, 2011
Freeze Warnings and Frost Advisories have been posted for the entire state of Vermont.

The National Weather Service office in Burlington has posted a freeze warning for our area, and indeed the entire state of Vermont is under either freeze warnings or frost advisories, so cover up vegetation as necessary. This may also be a good time to look into local furnace maintenance services as you want to be sure your current furnace can meet the demands of this cold weather. Companies like CJS Heating offer such services. Why now? Well, furnaces have to work much harder when the weather is colder and so some may struggle to keep up. The last thing you’d want is for it to stop working whilst temperatures are so low. Though the first frost for valley locations in the Central and Northern Green Mountains does typically happen in September, the average date for the occurrence is toward the end of the month (September 27th for Morrisville and September 30th for Montpelier) so this is a bit on the earlier side. Yesterday in the Northern New England thread at Americanwx.com, Powderfreak posted the chart from the National Weather Service that shows the average dates and ranges for first frost at some of our Vermont climate locations – mid September is in the 10th – 25th percentile. Take a look at that post for more information about average dates of 32 F temperatures around the state.
