It’s a winter wonderland for many of us as we start our Wednesday morning. The region has been dealing with snow of varying intensity and coverage area for the last 24 hours as we’ve essentially dealt with a two part storm system. Going back to late Monday night into Tuesday, many areas north and west of the Lehigh Valley saw steady snow and several inches as clipper low pressure moving into the Great Lakes dragged a cold front into the region. As this front approached however, it slowed down and basically stalled across central Pennsylvania. This front brought the first wave of snow, but because it slowed down and essentially stalled across central PA, much of the snow that occurred late Monday night into Tuesday stayed more to the north and west. Once you got down into the Lehigh Valley and certainly points south and east of there, it was basically just a period of some light snow in the morning bringing a light coating, and then just occasional flurries or a snow shower for the remainder of the day. That all changed this past night however, as the cold front to our west and clipper low transferred energy to a coastal low east of the Delmarva. That system is taking over and lifting northeastward this morning. In this process, steady snow transitioned south and eastward to those areas that didn’t see much during the day Tuesday, and now accumulations have increased and more slick travel conditions have been seen as well. Interestingly enough, temperatures are running close to 32 for many, so the snow that is falling is fairly wet. In fact, once you get down to the Delaware Valley region near I-95 and points south and east of there, the precipitation has been mostly rain with temperatures being several degrees above freezing.

 

Steady snow (mostly light, but occasionally moderate or even heavy) for early Wednesday morning will pivot from west to east across the area, eventually tapering to snow showers and flurries and likely coming to an end by late morning. The snow will likely hang on the longest into New Jersey where it could go until close to noon. While the snow will gradually wind down for many during the morning commute, there will still be plenty of slick travel conditions to be mindful of. Bottom line…everyone should be done with snow for good by lunchtime with skies clearing for the afternoon. No real changes with the expected snow totals. Areas along and north of Interstate 78 should see 3 to as much as 6 inches of snow, with the best chance for 6 inches towards the Poconos into Sussex County New Jersey. Isolated higher amounts are not out of the question for portions of northwestern New Jersey, the Poconos, and Schuylkill County. Farther south and east towards areas north and west of Interstate 95, accumulations of 1 to 3 inches are expected. South and east of the big cities towards central and southern New Jersey and Delaware, any accumulation should be under an inch as there are more issues with rain.

 

Coastal low pressure will be exiting away to our northeast as we progress through Wednesday and as it does so, a brisk northwest wind will start to increase. This breeze may blow some snow around so watch out for that with your travels. Otherwise, look for improvements for the second half of the day Wednesday with high temperatures expected to top out in the low to a few mid 30s. With the breeze factored in, it will feel like it’s well down into the 20s. Skies should be mostly clear by tonight with low temperatures expected to dip down into the teens with wind chills as low as the single digits.

 

High pressure centered across the Gulf Coast states will have a broad influence extending to the northeast over the next couple days and this system will ensure our weather for the remainder of the week will be quiet. A trough with the jet stream will remain in place across the Mid-Atlantic and Northeast keeping chilly air around. Look for mostly sunny skies Thursday with high temperatures around 32 degrees. A bit of a tight pressure gradient between the high pressure system well to our southwest and low pressure well off the coast will keep a brisk west wind in place. This should once again make for wind chill values down in the 20s for Thursday afternoon. Breezes should lighten up a little Friday as low pressure moves further away off the coast and high pressure starts to slide by to our south. With ample sunshine expected Friday and more of a southwesterly wind flow taking shape, look for high temps to climb into the upper 30s to near 40 in some spots.

 

High pressure will move off the coast for the weekend allowing a south to southwest wind to continue to pump in mild air. Look for highs both Saturday and Sunday to top out well into the 40s with perhaps a few spots getting to 50. Saturday is looking mostly sunny, but clouds will thicken and increase on Sunday however we should remain dry. There should be no weather issues at this point for the big NFC Championship Game in Philadelphia Sunday evening. On Monday, a cold front will start to approach from our west and out ahead of this front, there will be more mild air on a southerly wind flow. High temperatures Monday are expected to hit 50 and we should see mostly cloudy skies. As the cold front to the west gets closer, some showers will be possible later in the day. The cold front is expected to move through Monday night into Tuesday morning bringing a better chance for rain. Clearing skies are expected progressing through the day Tuesday as a gusty northwest wind ushers back in cooler and drier air.
