More Vermont Fire Risk Before Wintry Blast, Hard Freeze, Then Spring

Lots of wannabe lilac blooms on my big lilac
shrub in front of my St. Albans, Vermont house. 
Crossing my fingers they will survive 
Wednesday night's expected hard freeze.

 You can certainly tell at dawn this morning where the first stirrings of a warming south wind had started and where it was still calm and cold.  

It was in the low 40s in the Champlain Valley where a steady south wind was already blowing, but in the mid-20s elsewhere in Vermont after a clear, calm night. 

Those south winds will increase areawide today, giving us a quick squirt of warm air before winter unfortunately returns for a brief visit. 

The air is still really dry and is expected to stay that way all day. Winds gusting to 30 mph continues the fire danger that started yesterday.  

Yes, it's muddy underfoot still, and there's vernal pools in the woods. But the dead grass and leaves from last autumn have dried out in the sun. That's what can catch fire. Those fires can spread fast in today's winds. 

So, for the second day in a row, the Vermont Department of Forests, Parks and Recreation has us in a high fire danger for the day. 

WINTER

The kind of respite from this brief period of fire risk is not the kind we want. 

Rain will break out overnight, then change to snow - yes, snow - during the afternoon Wednesday. That's normally the warmest time of day this time of year, when temperatures should be approaching 60 degrees.

Not on Wednesday! Temperatures in the 40s will crash through the 30s in the afternoon.  Snow will accumulate even in many of the valleys. Not much, though. Perhaps a dusting to an inch.  But it's still harsh. 

That's not the real problem this time of year. It's the temperatures. 

These lilac buds died and failed to bloom after
this harsh winter storm and freeze in April, 2021
Not nearly as much snow as that episode is expected
with the upcoming freeze, but temperatures will
fall far into the 20s by Thursday morning.
Coldest hollows will be in the upper teens. 

They'll go below freezing in the late afternoon and evening and stay subfreezing into Thursday morning.

 Skies will quickly clear and winds will die down overnight. That means lows by Thursday morning ranging from around 18 in the cold spots to maybe 30 degrees right next to Lake Champlain.

That puts most of us in the 22 to 27 degree range. 

That's similar to the horribly damaging freeze of last May 18. Thankfully, plants and trees aren't nearly as far along now as they were last May. 

Trees haven't leafed out.  Fruit trees aren't flowering yet. So damage this time will be much less.  Those orchards are budding for sure, but fingers crossed I think most (but perhaps not all) of those buds should make it through this cold snap. 

Vineyards are probably relatively safe, too.

Because it is before the official growing season, there won't be any freeze warnings in Vermont with this. We should be glad this frigid episode isn't happening a couple weeks later than it is.

Still, this might be a disheartening spell for gardeners, like me. If your magnolia tree is blooming and those blooms survived this morning's freeze, enjoy them today. Those blooms will be brown wreckage by Thursday. 

It'll be interesting to see how hardier early plants do. My lilacs have tons of flower buds, more than in most years, so I was looking forward to a huge lilac season.  

I do worry this will be like 2021, when my lilac buds ended up failing to flower after dying in a harsh snowstorm and deep freeze. We shall see, but I'm not super optimistic. 

This is turning out to be yet another spring in which plants outside start to bud and blossom too early because of oddly warm weather. Then a harsh freeze threatens them. It's become a depressing spring pattern. With this frigid spell, it will be the fifth year in a row it's happened, with varying degrees of damage. Mostly relatively minor, except for last year. 

It's the new, changed climate.  It's generally warmer than it used to be, so spring advances earlier than it once did. But the new climate is also more extreme, so we get these brief blasts of winter air to cause potential damage. 

SPRING 

These spring cold blasts are always very brief, and this one will be no exception. Thursday will be cold for the season, with highs in the 40s, and another nasty frost/freeze is likely Thursday night. Though it won't be as cold as the night before.

By Friday afternoon, we'll be well into the 50s, Saturday will see highs passing 60 degrees and we could get into the low 70s by Sunday or Monday.
