Wednesday, January 16, 2019 - Morning Weather Discussion

Major and potentially crippling snow/ice storm to affect our area this weekend and then brutally cold Monday…

A cold front will pass through our area today, bringing a chance of a snow flurry this afternoon or evening. Highs will be in the 30’s.

Tomorrow, clouds will increase in the afternoon, with light snow developing at night as a disturbance passes through our area. Highs will be in the upper 20’s to mid 30’s.

Friday, the light snow will end in the morning, possibly ending as light rain near the coast. There could be a coating to an inch or two of accumulation throughout our area. Highs will be in the upper 30’s to mid 40’s.

This weekend things are going to get very interesting as a storm system will start to develop over Oklahoma. This storm will track eastward along a frontal boundary, reaching Arkansas Saturday morning, Tennessee Saturday night, Virginia Sunday morning, and the NJ Coast midday Sunday. There will be very cold air to the north of this storm and very warm air to the south of this storm, which will cause heavy precipitation and strong wind. The storm will be pulling in copious amounts of moisture from the Gulf of Mexico as it heads eastward. Right now, it is appearing as if the Allentown Pennsylvania and New York City Metropolitan areas will be on the dividing line between rain and snow, with a very heavy mixture of snow, sleet, freezing rain, and rain throughout our area. Liquid equivalent amounts will likely be 1.5-3.5 inches throughout our area. This will mean extremely heavy and potentially crippling snow amounts in areas that receive all snow (right now that is looking to potentially be far northern sections of Northeastern PA), with the potential for an equally crippling area with a mixture of very heavy snow and ice (right now that is looking to potentially be East Central and Northeastern PA, Northern NJ, Southeastern NY State and Fairfield County, CT), and a heavy mixture but mostly flooding rain in Central NJ and on Long Island. Please keep in mind this is based on the track of the storm as it is currently projected. Any small shift in the track of the storm will either bring the snow and ice amounts further southeast, or the rain amounts further northwest. 

This all means that clouds will increase Saturday morning with snow developing in the afternoon or evening from west to east across our area, becoming heavy at times at night. Highs will be in the upper 20’s to mid 30’s.

Sunday, we will have snow, possibly mixing with or changing to freezing rain, sleet, and rain in East Central and Northeastern PA, Northern NJ, NYC, Southeastern NY State, and Fairfield County, CT, and possibly changing to rain in Central NJ, NYC, and on Long Island. The precipitation will be heavy at times and there could be significant and possibly very significant amounts of snow and ice throughout our area. The precipitation could change back to snow briefly before ending Sunday afternoon and evening. There will be flooding in areas that receive mostly rain with total rainfall amounts of 1.5-3.5 inches possible. It will also be windy, with gusts up to 40 mph possible inland and 50-60 mph possible along the coast and on Long Island. Lows will range from the mid to upper teens in Northeastern PA, to the upper teens to mid 20’s in Northern NJ, and the mid to upper 30’s in Central NJ, with highs ranging from the mid 20’s to low 30’s in Northeastern PA, to the upper 20’s to mid 30’s in Northern NJ, and the low 50’s in Central NJ and on Long Island.

An early look at possible snowfall and ice accumulations BASED ON THE CURRENTLY PROJECTED STORM TRACK:

2-6 inches:  Central NJ and Long Island

3-7 inches:  New York City

5-10 inches: East Central PA, Northern NJ, Rockland, West Chester and Putnam Counties in NY and Fairfield County, CT

9-18 inches with up to 24 inches possible in far northern sections:  Northeastern PA

Total possible ice accumulations:

A trace to a half inch:  Central NJ, NYC, Long Island, and Coastal Fairfield County, CT

A half inch to 2 inches:  East Central and Northeastern PA, Northern NJ, Southeastern NY State, and inland Fairfield County, CT

Very cold air will then move in behind the storm Monday, with variably cloudy skies and a chance of a snow squall, snow shower, or flurry as some Lake Effect moisture may reach our area. Lows will drop as low as the mid single digits below zero in Northeastern PA, to the upper single digits above zero on Long Island, with highs from the mid single digits in Northeastern PA to the mid teens in Central NJ, NYC and on Long Island.

Tuesday will then be nice, but cold again in the morning, with lows from the low single digits below zero in Northeastern PA to the low teens on Long Island, and highs in the 20’s.

Next Wednesday will then be variably cloudy with highs in the mid 30’s to low 40’s.

Next Thursday rain or snow will be likely as a storm system will approach from the Southeastern United States. Highs will be in the 30’s to low 40’s.

Next Friday through Tuesday then look unsettled with a chance of rain or snow showers next Friday and snow showers next Saturday through Tuesday, as a couple of disturbances pass through our area. Highs will be in the upper 20’s and 30’s next Friday, the 20’s next Saturday and Sunday, the mid 20’s to low 30’s next Monday, and the 20’s to low 30’s next Tuesday.
