Hello again, South Jersey, and good Tuesday morning to you all! As a quick overview of the forecast in general, this week may end up being a tale of two weather patterns. As we all felt, yesterday was a rather chilly and blustery day, and we were treated to some snow flurries/showers this morning (Another round is possible tonight...more on that in a bit). If you like you December days on the mild side, stay patient for two more days. A gradual and rather significant warm-up will likely begin later this week and go right into the weekend. Let's start with the here and now, and what we're dealing with is a fast moving Alberta Clipper, an area of low pressure with origins in (You guessed it) Alberta, Canada. These systems are using rather fast moving and don't hold too much in terms of moisture, but if they arrive at the wrong time, they can still cause some problems for commuters. Case and point: This particular system has been causing problems to our north and west while still creating a few slick spots this morning with the scattered snow showers we had seen earlier today. Any other bits of moisture should fall in the form of rain through the day as warm air is channeled up the coast and into our region. Highs will climb into the low to mid 40s with a southeast wind at 10 to 15mph. Overnight, however, we will keep an eye on the back edge of this system. Some re-development is possible, and as a result, a second round of scattered snow showers cannot be ruled out. I'm not expecting much...no more than half an inch of accumulation, and that's the further north and west you go. Otherwise, we're mostly cloudy, breezy and cool tonight with lows in the upper 20s and a northwest wind at 10mph. High pressure then builds into the region from the west, and a slightly weaker northwesterly flow takes hold once again. Highs may only reach the upper 30s under gradually clearing skies with west by northwest winds at 10 to 20mph. Wind chill values may be in the 20s.
Once we reach Thursday, high pressure begins to shift to the east, and that's where a big change begins. We find ourselves on the western and warmer side of this core of high pressure, and that will be reflected in our high temperatures on Thursday. Our average high is 46 degrees...we'll be rather close to that under partly to mostly sunny skies, but that's just the beginning. A stronger surge of warm, southerly air will move to the east and eventually arrive on the east coast. Once it does, get ready for temperatures that will be 10 to 15 degrees above average by day AND night. We'll remain dry on Friday with highs in the mid 50s under partly sunny skies, and while cloud cover increases on Saturday, I think this southerly flow will be strong enough to compensate for that and still allow us to reach (Or at least come close to) the 60 degree mark. This unseasonable warmth goes through the rest of the weekend, but there's a catch. An area of low pressure will come into play on Sunday and into Monday, giving us a decent chance for some rainfall. While highs peak in the low to mid 60s on Sunday, you'll likely need an umbrella. From there, keep the umbrellas on hand for Monday, and also keep an eye on the thermometer. Warm air will begin to depart and be replaced with cooler air for the start of the work week.
Have a great day!
