Sunday, March 20, 2016; The Vernal Equinox
Happy Spring Equinox!
This morning in Huntington at 8:15AM it’s currently 16 degrees under clear skies. Winds are calm. Relative humidity is 86%, dewpoint 13, barometric pressure 30.27”. Yesterday’s high was 33, and the overnight low was 10.
High pressure will deliver one more calm, sunny and cool day today before sliding to our east. A coastal low will bring clouds tonight and tomorrow morning, but no snow to our region. More involved weather will be on tap for the middle of the upcoming week.
We’ll see sunny skies today with highs in the upper 30s and light and variable winds, becoming northerly around 10 mph this afternoon. Tonight should be partly cloudy with lows around 20 and southwest winds around 10 mph until midnight, becoming light and variable.
Monday should be mostly cloudy in the morning, then becoming partly sunny. Highs will be in the mid 30s with northwest winds 10 to 15 mph. Monday night should be partly cloudy with lows around 17 and northwest winds 10 to 15 mph gusting up to 25 mph.
Tuesday’s looking partly sunny with highs in the upper 30s and west winds 10 to 15 mph. A clipper system will move across the region Tuesday night bringing light snow with accumulations of a dusting to 2″ possible overnight. Lows will be in the upper 20s. Chance of snow is 70%.
Last year on this date we had a high of 38 and a low of 8. We had 15.25″ of snow at the stake.
Burlington averages for this date are highs of 41 and lows of 24.
The record high was 80°F again in 2012 (we had a high of 79).
The record low was -2°F in 1949.

The Venal Equinox occurred this morning at 12:29AM. This is the point in the earth’s orbit around the sun when the tilt of its axis is perpendicular to the plane of the sun allowing for equal amounts of day and night time at the equator. It also marks the astronomical beginning of spring. You can read more about equinoxes here.
Astute observers may have noticed, however, that the day on which we had 12 hours of daylight and 12 hours of night occurred on March 17th. This is our “equilux” date. Here’s a discussion of why our daylight is actually longer than our nighttimes on the equinox (drawn from Wikipedia):
“…from the Earth, the Sun appears as a disc rather than a point of light, so when the centre of the Sun is below the horizon, its upper edge is visible. Sunrise, which begins daytime, occurs when the top of the Sun’s disk rises above the eastern horizon. At that instant, the disk’s center is still below the horizon.
Second, Earth’s atmosphere refracts sunlight. As a result, an observer sees daylight before the top of the Sun’s disk rises above the horizon. Even when the upper limb of the Sun is 0.4 degrees below the horizon, its rays curve over the horizon to the ground.”

We came across this wild turkey hanging out in a Norway spruce in Norwich yesterday. Interestingly, juxtaposed with the image of bald eagles yesterday, these two species represent the winner and runner-up in the American National Symbol contest as Ben Franklin favored the turkey over the bald eagle.
