Arctic Cold Front Quick Burst Mix Snow Near Record Lows Wednesday Morning
The arctic front is moving eastward and we are seeing its impacts across upstate NY where snow has been developing today north of I-90. Over us we are in the warmer air for the time being and we will see temperatures hold there own overnight until the front passes sometime before daybreak and then the wind shifts to the north and temperatures start to fall. There is very little going on south of the boundary so we don’t expect any rain ahead of the front. All the precipitation comes behind it.
Regional radar shows snow developing across upstate NY and the southern edge is showing up on the Upton radar. Most of that precipitation is aloft though some mix precip is reaching the ground well to the north. We will see the local radars get busy late tonight as the front pivots eastward.
LOCAL RADAR NEW YORK CITY
We are talking about 3 hours or so where it could be cold enough for snow. Temperatures will be dropping on Tuesday so the highs will be overnight and before 7am when the front passes. The burst comes and goes. It leaves a coating to an inch on colder surfaces and elevated areas and it is done by early afternoon for most areas.
After this all comes to an end, it is all about the cold which I believe is the bigger story here. Temperatures will be dropping into Wednesday morning when we hit the teens to lower 20s. This will set record lows in many areas.
Skies clear out Tuesday night and Wednesday will be a day of ineffective sunshine with highs just barely back into the 30s. These could also set records for “record low high temperatures” We will moderate a bit on Thursday though clouds will develop as the high moves to the north and a bit of an onshore flow develops. Highs Thursday should be back into the 40s after a cold night Wednesday night.
