Some Changes To Roller Coaster, Sometimes Wintry Vermont Week Forecast

That looks like perlite in my St. Albans, Vermont perennial
gardens, this morning, you know, the white pellets
that you see in potting mix. But it's snow pellets that
fell when a cold front passed through overnight. 
Wintry periods are in the forecast this week. 

 Right on schedule, the second of three "bowling ball" shots of cold spring air rolled into Vermont around midnight. It was accompanied by a whoosh of wind, gusting to 40 mph or so, and a few showers of graupel.  

(Graupel is sort of a combination snow and glorified small hail).

Skies cleared behind the front super fast, and it was clear by the time we woke up this morning. It's cold for the season this morning, but not wildly so. It's around 30 to 32, with mid 20s once you get up to 1,000 feet above sea level or so

FIRE RISK TODAY?

The air arriving today is super dry.  The humidity this afternoon will be in the 20 to 25 percent range, which is very low. The sun will be out and winds will gust to at least 25 mph from the northwest.

This is a recipe for fire weather. As noted in a post last week, these bursts of low humidity and wind dry out things super fast. That dead brush from last year can easily catch fire and the winds would spread it quickly. 

The Vermont Department of Forests, Parks and Recreation has all of Vermont in a high fire danger today.

So: No burning your brush pile, no flicking your cigarette butts out your car window and no playing with fire in your backyard today, please. 

It'll also be cool for the season with highs in the 40s to around 50 in the warmer valleys. Another freeze comes tonight.

TUESDAY

Much warmer ahead of our next bowling ball of cold air. Clouds will increase slowly during the day. Winds will turn gusty from the south. I think there will be another relatively high fire risk during the day. Humidity will be a little higher than today, but those gusty south winds would spread any fire that does start pretty effectively. 

Spring will return by afternoon - briefly - as we get into the 60s.

WEDNESDAY WINTER

We'll start off rainy on Wednesday but cold front - another bowling ball of chilly air - will blast in during the afternoon. It's going to be a crappy Wednesday afternoon to say the least. As temperatures crash downward through the 40s and into the 30s, rain will change to snow. 

The only good news is that the American computer model that I mentioned yesterday has backed away from the idea that it had about us getting several hours of heavy, wet snow.

Instead, dry air will sweep in, ending the snow for the most part in the evening. 

I am somewhat worried about how cold it will get Wednesday night and early Thursday morning. Temperatures will fall well into the 20s, with low 20s fairly common in northern Vermont. A few cold hollows could hit the upper teens. 

So, you magnolia blooms will certainly be toast.  If any fruit trees are blooming early, they're in trouble. Luckily, most are budding so that will minimize the damage. Unlike last May when a killing freeze hit orchards while trees were in full bloom. 

Some garden perennials could get damaged, too, we shall see. Most I think will make it through OK.  

THURSDAY AND BEYOND 

We'll shake our brief excursion back to winter. Thursday will be a sunny, dry, chilly day, much like today. Thursday night will bring us another freeze, but probably not one as intense as Wednesday night's.

After that, regularly scheduled springtime will return. We just have to get through this weird weather week. 

Showers - rain showers to reassure you - might return by next Sunday.  We could even see some temperatures in the low 70s a week or so from now, too.
