Columbus Day got off to a chilly start with a morning low of 47 degrees in Central Park. That's the first time the temperature has been below 50 since May 16th. With high pressure off to the northwest, cool, dry air will continue pouring into the region through tonight. While it will be sunny, this afternoon's high will only reach 60 degrees and tonight's low could dip into the mid 40s in the city. It will be much cooler away from the water. Frost advisories have been posted for the Hudson Valley from Orange and Putnam Counties northward and a hard freeze is expected for much of Upstate north and west of Sullivan County. Fun fact: The earliest snowfall on record happened 37 years ago today, when a trace of snow was measured in Central Park.
The front this chilly air pushed through the city yesterday teamed up with moisture from now ex-Hurricane Matthew to provide much needed rain over the weekend. Central Park and LaGuardia airport received more than a half-inch of rain, while well over an inch fell on JFK. The heaviest rain fell where it was needed most, as much of eastern Long Island had over 1.5 inches of precipitation.
Don't look for it to rain again anytime soon. High pressure on the ground and subsiding air aloft will make for clear skies through Thursday. According to the National Weather Service, a "moisture-starved" cold front will pass on Thursday night, followed by another high pressure system arriving on Friday. That adds up to mostly clear skies through Sunday.
Afternoon highs will gently rise from near 60 today to maybe the low 70s on Thursday, before dropping back down to the mid 60s for next weekend.
