Area Forecast Discussion National Weather Service Mount Holly NJ 641 AM EDT Mon Apr 20 2026
WHAT HAS CHANGED
The Freeze Watch has been upgraded to a Freeze Warning for tonight.
KEY MESSAGES
1. A strong cold front passes through the region into this morning leading to below normal temperatures. Frost and freeze headlines remain in place due to these below normal temperatures.
2. A return to above average temperatures later this week before cooling down again over the weekend. Widespread rainfall possible over the weekend.
DISCUSSION
KEY MESSAGE 1...A strong cold front passes through the region into this morning leading to below normal temperatures. Frost and freeze headlines remain in place due to these below normal temperatures.
After a chillier night with frost and freeze headlines, we see temperatures today reach into the mid 40s to mid 50s for many. Some mid-level energy rotates through the region today allowing for the potential for isolated showers to develop mainly southeast of the I- 95 corridor. Generally, these showers will be in the form of light rain but the cold air aloft may allow the potential for some graupel to mix in.
Behind the cold front, a high pressure system moves east out of the Great Lakes region and overhead tonight. This high pressure system allows for a good opportunity for radiational cooling with a clearing sky and light winds. A widespread freeze looks to occur tonight into early tomorrow morning and a Freeze Warning is now in effect for the whole area except for the immediate coast. All of our counties now have an active growing season due to the recent excessive warmth. Blooms/vegetation have quickly initiated and in some cases are ahead of schedule. Fruit trees and other cold sensitive plants already planted are of the most concern. Frost formation might be somewhat limited given a much drier low-level air mass in place tonight. Lows tonight generally range from the mid 20s to low 30s with mid to upper 30s near the coast.
KEY MESSAGE 2...A return to above average temperatures later this week before cooling down again over the weekend. Widespread rainfall possible over the weekend.
A very cold start to the day Tuesday as the center of high pressure shifts offshore, and high temperatures will continue to be several degrees below average. It is not anticipated to be as cold Tuesday night as the air mass continues to modify and clouds increase. A return, southerly, flow will also become established Tuesday and continue Wednesday. This along with an increase in warm air advection and rising heights will result in temperatures climbing back above average Wednesday through Friday. Highs for most of the area are forecast to be in the mid/upper 60s Wednesday, then into the 70s for Thursday and Friday. A front may arrive Friday into Saturday with some showers, and with the low-level flow more onshore it will bring in some cooling starting Friday especially closer to the coast. If the marine influence ends up being stronger Friday into Saturday, then more low clouds may come into play along with even cooler temperatures. An area of low pressure may arrive during the weekend, especially for Sunday, bringing the potential for widespread showers or a period of rain. The strength and timing of the involved features however is lower confidence. The pattern that is currently indicated among the model guidance however would result in temperatures dropping to average or below average over the weekend, with an increased chance for rainfall.
