Good Wednesday morning to you, South Jersey, and Happy Hump Day as well! Showers began to move through the region through the tail end of the overnight period, and they have spread in coverage from western Cumberland County to the entire region. This is all due to an area of low pressure that will run along last night's cold front, which has stalled just beyond the New Jersey coastline. Scattered showers will move through the area over the course of the day today and through the evening as well. One thing you may have noticed already is the sharp difference in the temperature outside. It was 71 degrees yesterday afternoon for a high temperature, and today we'll be lucky to reach the mid 50s on the mainland and beaches since the aforementioned cold front passed through the area late last night. Skies will remain cloudy through the day with a northwest wind at 5 to 15mph. Showers will gradually taper off through the evening and into the night. High pressure will then begin to nudge to the east from the Great Lakes and begin to clear us out overnight as well. Temperatures will drop further than what we saw last night...upper 30s on the mainland and low 40s on the coast with a northwest wind at 5 to 10mph. That northwesterly wind both at the surface and further up in the atmosphere will continue to channel cooler air down into the Northeast from Canada. Along with that, the jet stream will also dig well to our south and allow for that cooler air to pool into the region.
The setup mentioned above will remain with us through the rest of the work week and into the first half of the weekend. Skies will remain partly to mostly sunny with below average temperatures by day and by night. Highs will struggle at times to reach the mid to upper 50s on the mainland and mid 50s on the coast by day, with lows near 40 on the coast and low to mid 30s on the mainland. It's the mainland lows on Thursday and Friday night that will be monitored for the potential for some patchy frost. There is no widespread frost or killing freeze in the forecast. Either way, this potential hinges on what kind of cloud cover (If any) we see at night as well as the wind. A calm wind will allow for frost to form. A breezy night will circulate the air at the surface and not allow for the formation of frost. If any advisories are posted, your NBC40 weather team will keep you posted. At any rate, a modest warm up may begin to take hold of the area as early as Monday with highs near 60 under sunny skies. Winds will begin to shift to a more southerly direction and bring up some warmer air, but it won't be a significant event. Rather, we should at least be able to return to near average temperatures by day and night through the middle of next week.
Have a great day!
