Possibly the Last Chilly Week

Discussion: The lower heights will soon move out of NJ. A series of ridging will then build over NJ for much of the foreseeable forecast period (through next weekend). An upper low departs the lower Mid-Atlantic US Mon-Tues. Then a shallow and progressive trough/upper-low brings a rainy disturbance Tuesday night through most of Wednesday. We see some chillier conditions behind that system (for Thursday) but then we start a nice gradual build into 70s statewide by the end of the weekend. In addition to tonight’s, Thursday and Friday nights should be the last of the frost advisories for a while. Most of NJ should break 70 every day next week/weekend (coasties might hang in 60s a few days) as the ridging locks in. There’s a second rainy disturbance showing for Saturday but I am skeptical of it for now. Need a few days to see if model guidance agrees with me lol.

Monday (April 22) high temperatures cracked 60 for some areas away from the ocean. Otherwise, another day in the 50s for all other areas including the SNJ coasts. Skies are clear and winds are light out of the NW. Overnight lows should fall into the 30s for most NJ locations, warranting the widespread frost advisories issued by the National Weather Service for 2-9am tomorrow morning. Coastal areas should hang just above 40.  

Tuesday (April 23) high temperatures, after a chilly morning, should rebound quite nicely to 60s, possibly 70 for most NJ locations. Coastal areas maybe just at 60 or 1-2 degrees below. Skies should be mixed with sun and clouds with thicker clouds building into evening/overnight hours. Winds should be light out of the S. Overnight lows should fall to the 45-50 range with cloudy skies and rain showers around by daybreak Wednesday.

Wednesday (April 24) high temperatures should reach the mid-to-upper 60s for most NJ locations. Skies should be mostly cloudy with periods of rain likely. Winds should be breezy out of the W/NW. Overnight lows should fall back into the 30s/40s as skies improve. Can’t rule out more frost advisories for Thursday AM.

Thursday (April 25) high temperatures should reach the low-to-mid 60s for most areas. Coastal areas could hang in the 50s. Skies should be mostly sunny. Winds should be light out of the E, possibly breezier out of the E for coastal areas. Overnight lows should fall into the 30s for most with more frost advisories likely.

Friday (April 26) high temperatures should reach the mid-to-upper 60s. Can’t rule out some interior areas running at 70. Coastal areas could struggle to break 60. Skies should be mostly sunny. Winds should be light out of the S/SE for most, but breezy off the ocean for coastal areas. Overnight lows should range from mid-30s to mid-40s from NNJ elevations to SNJ coasts. Can’t rule out more frost advisories, especially for NNJ elevations.

An early look at the weekend indicates warmer temperatures setting up. Saturday looks like mid-to-upper 60s/some 70s but slightly unsettled. Sunday looks like statewide 70+ and such conditions should hold through at least next weekend. Have a great week and please be safe! JC
