Monday, September 22, 2014; the Autumnal Equinox
This morning in Huntington at 6:30AM it’s currently 56 degrees under overcast skies. Winds are calm. Relative humidity is 96%, dewpoint 55, barometric pressure 29.58” and rising. We picked up 0.34” of rain overnight. Yesterday’s high was a summery 81, and the overnight low was 56.
The surface cold front which brought showers to the region overnight will shift east of the region today and andy scattered showers should taper off this morning. We’ll see mostly cloudy skies with a chance of showers this morning. It’ll be on the cool side again with highs only in the mid 50s and west winds 10 to 15 mph gusting up to 30 mph. Chance of rain is 50%. High pressure will begin moving in tonight bringing partly cloudy skies with lows in the upper 30s and west winds 10 to 15 mph.
Tuesday should be partly sunny with highs in the lower 60s and southwest winds around 10 mph, becoming westerly in the afternoon. Tuesday night should be mostly clear with lows in the lower 40s and north winds around 10 mph.
Wednesday’s looking sunny with highs in the mid 60s and light and variable winds. Wednesday night should be clear with lows in the mid 40s. At this point the trend is for gradually warmer and continued dry weather into next weekend.
Last year on this date we had a high of 62 and a low of 45. We picked up 0.67″ of rain.
Burlington norms for this date are highs of 68 and lows of 48.

The Autumnal Equinox occurs today at 10:29PM. Equinoxes, like solstices, occur twice a year—in March and September—and mark the time when the the earth’s axis (tilted at 23.5°) is near perpendicular with the sun’s rays as the earth orbits the sun. Consequently, we get a near-equal amount of night and day. You can read more about the equinox here. Astute observers (John I…) will note that the length of day reported above is not exactly 12 hours. This is because of two things: the first is that “sunrise” is defined as the moment that the leading edge of the sun first breaks an imaginary plane of the horizon, and “sunset” is the moment the upper edge of the sun disappears below the horizon. It takes some time for the entirety of the sun’s disc to travel below the horizon, hence more daylight. Also, refraction causes the sun’s upper edge to be visible from Earth several minutes before the edge actually reaches the horizon, and, conversely, after it sets. I hope that explains it!

Robin & I biked the Richmond River Trail along the Winooski River yesterday morning. We came across this enchanting horsetail forest down near the mouth of the Huntington River. Lovely!
