After Our Vermont Morning Frosts, It's Back To Late Spring Warmth. Except A Nippy Sunday?

It's lilac season, as they blooms cascade over my deck
railing. Cool temperatures this Memorial Day weekend
will preserve the lilacs for awhile, but it won't exactly
feel like an introduction to summer. 

 The cold temperatures last night worked out about as forecast. We had widespread frost, with a large minority of places in northern Vermont going below freezing. 

Montpelier got down to 31 degrees and Morrisville was 29 degrees. St. Johnsbury was barely above freezing at 33 degrees. 

It looks like the Champlain Valley escape the frost for the most part, as temperatures there reached the upper 30s. Burlington had an overnight low of 38 degrees.

There was likely seen light frost across southern Vermont, too. Rutland, Springfield and Bennington all reported morning low temperatures of 35 degrees 

We have nice day on the way, with highs popping back up well into the 60s.  Some high clouds should return this afternoon, but those won't entirely hide the sun. 

Then we get into a Memorial Day weekend that looks, not great in the weather department. But we still have some questions about how much rain we might get and when it might fall. We do know it will be dry much of the time, at least on Saturday and Monday. Let's take a shot at the forecast here: 

SATURDAY

Not too bad, actually, especially north. If the clouds stay thin enough north, the day might begin with patchy frost in the normally colder spots, but the vast majority of us will be fine. It'll be a cloudy day, with the thickest clouds south.

That'll affect temperatures. Highs under the thicker clouds south will probably hold temperatures down into the upper 50s. Where the clouds are thinner north, weak sun getting through will hopefully push temperatures up to near 70.

SUNDAY

Unfortunately, if current forecasts hold, Sunday's weather will be almost as bad as it can get for this time of year. Almost, because there will be no disasters, no snow, or anything like that. 

But it won't feel like the introduction to summer it's supposed to be, either. Light rain should move in later Saturday night and continue much of Sunday. Worse, this is a cold system, so the lack of sunshine and the rain could well hold high temperatures to within a few degrees either side of 50. 

Some places, especially in wetter southern Vermont, could have a high temperature in the mid and upper 40s. You know, like late March,  not late April. 

The one ray of hope is there is some questions as to whether the high pressure system that gave us this morning's frost will at least partially block this system. If it does, there would be some breaks in the clouds and warmer temperatures, especially north. But that looks sort of unlikely at this point. 

The rain should be quite light, ranging from a tenth of an inch north to up to a half inch far south. 

MONDAY

OK, this won't be perfect, but it will be better. Winds from the west will import somewhat warmer air into Vermont. We'll still have a risk of showers, but temperatures should pop back up to near 70, which isn't far from normal for this time of year.
