Bitter Cold Next 2 Nights Snow Tuesday Appears Light

From the 60s to the 20s and 30s this afternoon; that has been the trip down we have been on. Cold air is building in from the Ohio Valley and Great Lakes and we are headed down into the single digits and low teens overnight into Sunday morning and again Monday morning.. Winds will be gusty at times from the northwest which will put wind chills down close to zero.

2PM TEMPERATURES

Radars are quieting down everywhere in the Northeast as yesterday’s frontal boundary and deepening wave of low pressure move on to Southeastern Canada. Radars should be silent for the most part into Tuesday. Skies Sunday and Monday should be mainly sunny. Sunday’s highs will be in the mid to upper 20s in most places and we should reach into the 30s on Monday.

A strong upper air disturbance is dropping southeast out of Central Canada and it will swing across the Great lakes and Ohio Valley Tuesday. As we indicated yesterday the European model was far more bullish than the others regarding snow and it appears that its bullishness for snow was unwarranted yet again. This model has been a very poor performer this winter showing major storms that wound up being non events and missing on the blizzard of 2 weeks ago. Instead it looks as if we will see a period of snow or snow showers later Tuesday and Tuesday night that probably won’t amount to much if anything at all. All the other weather models are on course with this idea that any coastal storm development would be way too far to the east. Even with a corrective westward shift it probably won’t be enough to create a serious issue.

The upper air jet stream in the west is changing and as a system moves into the Pacific Northwest it tears down the ridge of high pressure aloft there. You need that ridge to support any kind of storm in the East to move up the coast. Otherwise it moves out to the east which is what appears to be happening. Once that light event is done Tuesday night into Wednesday, we will be cold and dry until next weekend when things could warm up a bit. The action shifts to the west for a little while at least so we could get a much needed break from all the volatility of recent days.
