Tuesday Discussion : Winter Chill on the Horizon

With the passage of the cold front, autumn’s chill has settled back into the valley.  We had a brief warmup overnight, before the front pushed through.  Temps briefly climbed into the 60s before falling back into the 40s before sunrise.

For the rest of the day on Tuesday, we’ll have sunshine mixing with fair weather clouds, and light breeze.  Temps Tuesday afternoon will climb into the mid and upper 50s (about 5°) below average for this time of year.  Tonight… temps will fall into the upper 30s and low 40s around the region, with a light SW wind… but mostly clear skies.

That brings us to Wednesday, and the approaching of an arctic cold front.  Now… this time of year, an arctic front doesn’t mean the same thing it means in December and January… but it’s still going to pack a biting punch.  The front will drop south during the day on Wednesday, and increase winds out of the west/northwest during the afternoon.  Winds 10 to 20mph will gust upward of 30mph at times on Wednesday… and a spot rain shower can’t be ruled out.  In the Catskills… that could transition to snow showers, if the cold air moves in fast enough.

Behind the front, we’ll have a strong NW wind at 10 to 15mph, gusting over 20mph into Wednesday night.  Temps will plunge through the 30s… and into the upper 20s in some places.

This map shows the projected low temperatures Wednesday night… but this doesn’t factor in the 10 to 15mph wind, that will gust even higher at times.  That will generate wind chills in the mid 20s… and even some low 20s in the Catskills.  Surely the coldest air of the season so far.  Frost may not be a major concern due to the winds… but a hard freeze may still be an issue.  We’ll have to monitor the situation.

The cold will last through Thursday… when afternoon highs won’t get out of the 40s in the afternoon!  But as the weekend approaches, we’ll begin to see temperatures slowly climbing back toward average levels.  The change of seasons is upon us, Hudson Valley.  Make sure you’re bundled accordingly.  Have a great Tuesday!
