Thursday, September 22, 2016: The Autumnal Equinox
Happy Equinox and first day of fall!
This morning in Huntington at 8:00AM it’s currently 54 degrees under clear skies. Winds are calm. Relative humidity is 99%, dewpoint 53, barometric pressure 30.19”. Yesterday’s high was 78, and the overnight low was 49.
We’ve got one more day of above normal temperatures across the region today as high pressure gradually moves east of the area. Clouds will increase this afternoon and tonight ahead of a cold front moving down from Canada. The front will bring increased chances for precipitation after midnight tonight through much of Friday. The front will slide south of the area Friday night and behind it colder air will move in for the weekend. Quite appropriate for the beginning of fall!
We’ll see partly sunny skies today with highs in the upper 70s and light and variable winds. Tonight should be partly cloudy until midnight, then become cloudy with a 50% chance of showers after midnight. Lows will be in the mid 50s with southwest winds around 10 mph.
Friday showers are likely. Highs will be in the lower 60s with light and variable winds. Chance of rain is 70%. Friday night should be partly cloudy with lows in the lower 40s and north winds around 10 mph.
Cool high pressure will build in Saturday bringing sunny skies and much cooler with highs only in the upper 50s with northwest winds around 10 mph and gusting up to 25 mph. Saturday night should be mostly clear with lows in the upper 30s.
Last year on this date we had a high of 71 and a low of 43.
Burlington averages for this date are highs of 68 and lows of 48.
The record high was 88°F in 1965.
The record low was 31°F in 1962.

The autumnal equinox occurs this morning at 10:21AM. This marks the point in the earth’s orbit around the sun when earth’s axial tilt is perpendicular to the sun and day and night are just about equal in length (but not quite. Click here for more on this….) It marks the first day of astronomical fall for the northern hemisphere (spring for the south). Here’s a handy graphic showing the axial tilt of the earth’s pole and its relationship to the sun.

New England asters are still bright and attractive to pollenators. This honey bee (and many others) was getting the last of the nector from a large bloom of asters along the Stowe Rec Path yesterday afternoon.
