Yes, It Will Snow In Vermont Later Today. How Much Is Still A Question

Yup! Another NWS snow prediction map. Valleys
should get very littl e snow this afternoon, but 
the mountains and Northeast Kingdom could get
a few inches of new snow.

UPDATE:  Rain was already starting to change to snow in St. Albans, Vernont as of 9:50 a.m. The earlier changeover might mean more snow than forecast. I'm not sure on that, stay tuned!!

PREVIOUS DISCUSSION

If you got up early this Sunday morning, you enjoyed the last vestiges of the warm weather we just experienced. The high temperature today in Burlington looks like it was 61 degrees not long after midnight. 

It was still 57 degrees at 5 a.m. just before the cold front arrived. By 8 a.m. it was 48 degrees and rain was falling. 

Before we go on with the very bad weather news, let's reminisce briefly about Saturday. 

Southeast winds flowing down the slopes of the western Green Mountains often warm up a lot as they do so. Yesterday was no exception, allowing Burlington to get up to 76 degrees with the rest of the Champlain Valley experiencing similar temperatures. 

The rest of Vermont was in the 60s. The warmth and sunshine made for a gorgeous spring Saturday. 

Now for the depressing part. The snow, and the intense cold might do a number on some garden plants, depending exactly how cold it gets.  Here are the details

TODAY: 

The cold front is slowing down as it moves through Vermont and New Hampshire. That's allowing moisture to flow northward behind the front, ensuring a fair amount of precipitation all day. Notice I didn't just say rain.

Sure, a lot of this will be rain. But as temperatures fall into the 30s by afternoon, the rain will mix with and change to snow in many areas.   We're still struggling with how much snow we'll get.

Officially the National Weather Service forecast calls for a trace to an inch in most valleys, ranging up to four to seven inches on mountain summits. 

Most of us have removed our snow tires, so just a note that traveling could get tricky during the heaviest snow, especially in higher elevations. The ground is warm, so most of the snow will stick to grassy surfaces and  not roads. But the snow could be heavy enough in spots to make the roads slushy.

I'm also going to throw out a very slight chance of an unpleasant surprise. The kind of April surprise I'll describe has happened in the past, so it's possible.  Again, not likely, but it's a slight chance worst case scenario

The National Weather Service has a 10 percent chance that the snow could get really aggressive. Under this scenario, Burlington gets three inches of snow. St. Albans four inches, Montpelier 5 and Island Pond 9. 

The weather front now passing through is set up in a similar fashion to the big April snowstorms of 1983 and 2000. But there seems to be less cold air available than in those two occasions, which makes a big dump of snow today much less likely. 

Any snow might go back to a light rain for a time in the valleys as precipitation tapers off later today. 

TONIGHT

The only thing coming out of the sky tonight will be scattered light snow showers. The mountains could pick up another inch but everybody else will see no more than a dusting.  Especially for those of you with summer tires, some of the water out there on pavement could freeze, making for some icy patches. Yes, I know that's obnoxious for the third week in April.

Even worse, a reinforcing shot of cold air might rejuvenate the snow showers a bit toward morning.

MONDAY

Enjoy your spring blooms while you can. There's a good
chance that lows from 15-25 degrees Monday night
could destroy them. 

Monday will bring a throwback to mid-March. Stiff northwest winds will hold temperatures all day in the 30s to near 40. A few of the warmer valleys south could make it to the mid-40s.

Scattered  morning snow showers in northern and central valleys will tend to fade by midday but could continue in the afternoon across the Green Mountains. In other words, it will be a typical mid-March day. 

It'll be a good day to cut any flowers you have blooming and bring them inside to enjoy because.....

MONDAY NIGHT

Skies will clear and winds will go calm.  "High" temperatures are going to be so low on Monday it won't be much of a journey to get below freezing. And it will get far below freezing by dawn Tuesday. 

As of this morning, the National Weather Service is going for a low early Tuesday morning of 23 degrees in Burlington, 20 in Montpelier, 21 in Rutland and 17 in St. Johnsbury. Parts of the Northeast Kingdom and Adirondacks of New York could each 14 or 15 degrees. 

These aren't quite record lows, but are quite frigid for the third week in April.

As I've mentioned before, climate change has created earlier springs. Also more volatile ones. So, spring trees, plants and flowers bloom prematurely, only to get zapped by a freeze. 

Decades ago, a freeze of this magnitude during the third week of April would have been no big deal because plants would not have progressed far enough along to be damaged.   It's not every year in the recent past we've had damaging late freezes, but it's been frequent. I'm thinking late April, 2021 and especially May, 2023 as examples. We're going to add April, 2026 to this list 

Early spring blooms are tough and there will be survivors this time. But we won't know for weeks whether lilacs and other plants that are still budding but not quite blooming received damage or not. I know that daffodil blooms get wrecked at temperatures under 25 degrees. And depending on how far along lilac buds are, they have a good chance of turning brown and ugly too.

So this whole thing is just a depressing mess. The only hope is if we unexpectedly get increasing clouds or wind Monday night to hold temperatures a little higher.

BEYOND THE COLD WAVE

As we likely survey the wreckage of our gardens later this week, the weather, almost cruelly, will turn very, very normal.  Tuesday will still be quite cool, but the rest of the week will be pretty average, with highs i the 50s to around 60 and lows in the 30s to around 40.  It looks like there will be very little rain during this period. And more importantly, no snow!
