Good Tuesday morning to you, South Jersey! With yesterday's cold front advancing slower than anticipated, we were able to warm up several more degrees and enjoy what has been a rather rare day featuring above average temperatures. Once that front passed through the area, however, the bottom fell out from underneath that 47 degree high temperature, and we fell back into the chill box. Skies will remain partly to mostly cloudy as the leading edge of a cloud shield stays overhead. While this same cloud deck kept us insulated last night, it will also keep us from warming up too much. Highs will struggle to reach the low 20s on the mainland and coast with a north by northwest wind at 10 to 15mph. Wind chill values, as a result, will stay in the single digits. Our attention is then shifted to the south as an area of low pressure follows along Monday's frontal boundary and comes up to the northeast. This brings us to the trickiest part of the forecast for several reasons. First, a note. Winter weather advisories are up for Atlantic, Cape May, and Sussex county from 5pm this evening through 5am tomorrow for the potential of a few inches of snow...especially the further south and east you go. Initial snow forecasts feature a dusting to an inch towards the NJ Turnpike/I-95 corridor, 1 to 2" for much of mainland South Jersey, and 2 to 4" from EHT/The GSP/Route 9 and points south and east. There's a big catch to all of this, however. This all hinges on the northwest advancement of the northern fringe of this low pressure system. The latest trends have held steady on the more NW track, but that doesn't mean that it's set in stone. Trends can change, and as we've seen several times this winter, Mother Nature tends to throw a last second curve ball into the mix. In light of this, your NBC40 weather team will monitor any and all upcoming model runs and trends, and we'll keep you all posted on any changes that may need to be made (Good or bad) to the forecast. At any rate, lows tonight will drop into the low to mid teens with a north wind at 5 to 15mph.
Any leftover flurries will clear out before sunrise, allowing for a gradual clearing process to take place for the day tomorrow. We'll still be cold and a little on the breezy side, but highs should still be able to make it into the mid 20s across the board. Wind chills, with that northwest wind at 10mph, will likely range in the low to mid teens. Starting on Thursday, however, a modest warming trend begins to take over. A warm front will approach from the south and eventually clear the region, allowing temperatures to climb into the low to mid 30s under partly sunny skies, and that's just the beginning. 40 degrees is attainable on Friday with partly to mostly sunny skies throughout the region (Needless to say, by this point, any snow that we may or may not see will be shown the door). The weekend, while it is warmer overall with highs on both days in the low to mid 40s, may be a bit unsettled as well. We'll keep an eye on low pressure as it moves in, giving us a chance for some rain showers in the evening on Saturday before drying out on Sunday. All is clear so far for the start of the next work week with highs near 40 and partly sunny skies.
Have a great day!
