We have entered a pattern that will feature prolonged and brutal arctic air, with the occasional snow chance as well, this type of prolonged cold is something we have not seen in a long time but we are locked into this pattern through at least next weekend, and probably beyond that into the first half of February
We have an amplified trough locked in around the Aleutians which has pumped up a very amped up ridge in the East Pacific and western US, this leads to a NW flow directly out of the arctic for the eastern 2/3rds of the nation and with a pattern so amped up it will not be going anywhere anytime soon. We also have a stubborn and strong Atlantic ridge, so over the next few weeks we will have to watch out for more coastal lows/nor’easters although we will have to take each storm 1 by 1 and see how they will interact with the pattern etc.
For today the brutal cold will continue with highs in the lower teens interior to mid to upper teens elsewhere, maybe a few lower 20s along the immediate coast, there will also be a gusty Northwest wind to keep wind chills between -5 and 10 degrees area wide. Tonight clouds will increase as a clipper system begins to track towards the northeastern US with lows a BIT warmer but not by much with generally mid 0s interior to middle 10s along the coast.
Saturday a clipper and arctic front will pass through the area, this will bring snow showers and a period of light to moderate snow, most will be confined to eastern PA and western areas where 1-3 inches of snow is possible locally 4 is possible in squalls but that should be few and far between, east of the Delaware river a general coating – 2 inches can be expected with 1-2 inches more likely the farther west you are and coatings to 1 inch closer to the coast. Saturday night will clear out with gusty winds and lows returning to the negative digits interior, to the single digits along the coast , Saturday during the day will be warmer, and by warmer we are talking upper 10s to mid 20s overall for most of the area, coastal locations in the upper 20s to low 30s as a southerly wind develops ahead of the front
Sunday highs will returns to the 10s area wide but Sunday night and Monday will again be a bit warmer as a clipper tracks north of the area, not much impact to the area is expected but a southwest wind will moderate low temperatures Sunday night and highs on Monday generally in the mid 20s to lower 30s area wide, a couple of snow showers are possible at this time but nothing much unless we see a pretty drastic turn to a track farther south.
Beyond Monday we will have highs in the 10s area wide with lows anywhere from -5 to 10 degrees, there are a few systems to watch, the biggest one being a potential right around Super Bowl time, which is of course being held in East Rutherford NJ this year!
