Yeah, the low humidity season usually peaks in March and April here. Things should gradually moisten back up going into next week. Then it looks like our next chance of significant rain again in about a week. We saw this in March when we went from very dry to wet again. The main take away is that dry patterns don’t have much staying power in our new wetter climate. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=157&network=NJ_ASOS&station=EWR&year=2020&var=min_rh&dir=below&thres=20&dpi=100&_fmt=png

Looks like another low dewpoint and low relative humidity special today. Dewpoints are forecast to drop to near 0 with temperatures getting back above 50°. We make a run on 60° tomorrow and get back into the 60s on Monday. So it’s tough to maintain the record cold of the last few days very long.

This is only the 3rd April since 1990 with a NYC high temperature below 40°. The other 2 years were 2003 and 1995. It was also the first -14 daily temperature departure in NYC since November 18th.

Outside of the unusual cold today and tomorrow, I don’t think anyone is forecasting dreary and cold for the whole month. The models have the blocking shifting from Greenland back to Canada over the next few weeks. So we trade in Greenland blocking for more +PNA blocking as the month progresses. We could easily get 60s like the models show coming up. Highs to our north will probably mean plenty of NW to NE flow. Maybe a low will eventually try to cut off underneath leading to several days of more easterly flow and rains. Northeastern New Jersey...

These cool downs and blockier intervals following an early 80°+ day have become common in recent years. So the early April freeze coming up following the 80s last week isn’t a surprise. The first 80° at Newark has moved up nearly one month since the 1970s. The average back then was 4-23 and 3-30 since 2011. But the last freeze date has only moved up 4 days over the same period from 4-7 in the 70s to 4-3 since 2010.

Getting some heavy elevated convection along the warm front. -
The lower dewpoints for a good portion of the month finally allowed the maximum temperature departures to exceed the minimums. High temperatures were able to beat expectations. The drier conditions at night allowed the lows to get closer to normal.

This will be the first time that we had 4 freezes in 6 years following the first 80° of the season. These very early 80° degree readings make this possible.
