Record low temperatures were set this morning in the following locations:

LGA 23 Old Record 24 in 1975
JFK 23 Old Record 24 in 2001
ISP 22 Old Record 22 in 2001
EWR 22 Old Record 23 in 2001

We recovered nicely into to lower and middle 40s this afternoon. Which is still 10 degrees below normal. Party cloudy skies are expected tonight. Then it will mostly cloudy tomorrow morning. A cold front will move through the region tomorrow evening. Ahead of is 50kt-60kt low-level jet and precipitable water values (pwats) around .75″. This could some showers to develop tomorrow afternoon and evening. Heavy rainfall is not expected however. Amounts .25″ at best likely.

Shortwave energy will cut-off to our southwest on Saturday. As this system approaches our area, rain moving in from south to north. Rain is likely fall heavy times Saturday night into perhaps Sunday. 200mb-500mb jet streaks are positioned favorably for upper-level divergence (forcing). The cut-off low intensifies and takes negative tilt over Ohio Valley. This causes surface low pressure to form along the coast. Warmer, moist air will be transported with developing low-level jet. The heaviest rainfall is likely to occur with the best moisture convergence setup near the low-level jet and pwat axis. As the 18z run of the GFS shows for Long Island and Connecticut:

Overall it seems most areas are likely to receive at least 1-2″ of rain from this storm. With parts of the area receiving up to 3 or 4 inches of rain. Winds may also gust between 35mph to 45mph, near the coast on Sunday, with low-level lapse rates steepening and low-level jet in the area.The pattern will remain progressive overall with a parade of Pacific systems coming into Western and Central US. This will force this storm to move out of the region by Monday. With fair weather returning for much of next week. Temperatures will also be closer to normal in the 50s and 60s for highs.

The 12z GEFS hints another large storm system over Eastern US, about a week from now. However, with the polar vortex retreating into North Pole, artic/polar air source, will likely be shutoff next week.  We may see Pacific shortwave energy to cut-off again and bring more heavy rain to the area. Still very far out for any details:
