Sleet and freezing rain on the radar

Sleet and freezing rain on the radar

Even though its been so cold for the last 2 weeks, warmer air has worked into the air above the ground changing the snow to sleet and freezing rain as seen in the pink on the above radar.

So prepare yourself for more mixed precipitation than snow this afternoon

Heavy snow in Stewartsville, NJ

Heavy snow in Stewartsville, NJ

The Blizzard warning continues for all of western New Jersey. The powerful storm has formed and is impacting the area. Stewartsville has received 7.8″ of snow as of 10 am this morning. There has been more snow to our north and west.

The storm has formed further west than originally thought. This has allowed the upper atmosphere to be warmer than originally thought. This has resulted in sleet from time to time. Those areas that received a lot of sleet will see lower snow totals. All areas will change back to snow as the storm pulls away.

There has been several reports of thundersnow/sleet in NYC! This gives you an example of how powerful this storm is.

The areas in the blue hatch are where the heaviest snow will form from this storm going forward. Note this is further north and west as southern and eastern areas are getting sleet.

Winds will continue to be a factor.

The snow totals forecast has been adjusted due to all the sleet. Southern and eastern areas of western New Jersey will receive 8-12″ while further north will receive 12-24″ – higher totals in areas that do NOT change/mix with sleet

Brrr! Most locations in western New Jersey woke up to single digit temperatures. Some areas further to the north were below zero! Certainly nothing unexpected for January weather but still cold none the less.

Today will remain cold but at least there will not be as much wind as yesterday making it feel a little more comfortable.

Our next weather system will be moving to our north and west. This will put us on the eventual warm side of the storm. Eventual is the key word. There is a good amount of cold air and snow covered ground over western New Jersey right now. It will take a while for it to all be pushed out by warmer winds. This will result in Tuesday, main in the afternoon, of another snow to sleet to freezing rain day before it eventually turns to rain. Before that changeover I’m forecasting a coating to 1″ followed by some ice on untreated surfaces. To make matters worse this should still be happening by the afternoon rush.

This will be relatively light precipitation but it doesn’t take much to make things slippery. The only good news is there is a tremendous amount of salt on area roads so hopefully they will not be too bad.

Snow covered streets in Stewartsville

Snow covered streets in Stewartsville

The snow has already changed over to sleet in most sections of southern western new jersey. Look for all areas to go to sleet and then even freezing rain before ending by mid day.

Stewartsville received 0.8″ of new snow/sleet so far.

Frigid start to Valentine's Day in western new Jersey

Frigid start to Valentine’s Day 2016 in western New Jersey

The official low temperature in Stewartsville was 0 this morning. I’m sure there were several stations further north and west in western New Jersey that were -5 to -10 this morning. Brrr!

NWS "most likely" snow forecast for Monday into Monday night before changeover to ice and rain on Tuesday

NWS “most likely” snow forecast for Monday into Monday night before changeover to ice and rain on Tuesday

We will have another cold night tonight but not as bad as last night. Winds have slacked off and will go calm this evening. For the first part of tonight, look for temperatures to fall sharply. They should start to level off as high thin clouds begin to increase as the result of our next weather maker.

Look for light snow to overspread the western New Jersey area by mid day on Monday. Snow should be light to moderate at time Monday afternoon into the evening. At this time I’m forecasting 1-3″ of snow before a change over to ice and rain. Higher numbers will be to the north and west and less to the south and east.

NWS 7 day forecast for western New Jersey

NWS 7 day forecast for western New Jersey

Believe it or not, even with all this frigid air over our area now we are talking about rain on Tuesday. A storm is expected to move up the coast Monday into Tuesday and either go over us or more likely to our West. That will put western New Jersey on the warm side of the storm. Look for snow Monday evening and overnight to first mix with sleet and freezing rain then change completely over to rain before Tuesday morning. rain on Tuesday could be heavy at times with 1-2″ of rain forecast. This could result in some street and river flooding since the ground is so frozen right now.

Looking longer range we warm up a little by the weekend and that will continue into next week but colder weather looks to return the last week of the month

StormTotalSnowWeb1

The National Weather Service (NWS) has continued their winter weather advisory for tonight into early Tuesday morning. I’m expecting precipitation to break out over western New Jersey this evening from 7 pm – 10 pm. It could start out as a cold rain in some areas. Then the rain will cool the atmosphere a little more and the rain should mix if and possibly change to sleet for a few hours. Further to the north and west (near and north of I-80), especially in elevated areas, there could be some wet snow mixed in as well.

Warmer air will eventually take over and we should see all rain by the Tuesday morning commute. The changeover will take a bit longer further to the north and west. Given how warm the ground has been recently I expect little of any accumulation. At most there could be a little slush on colder surfaces like cars.

The most important thing to keep an eye on tonight is the air temperature. As long as we remain above freezing the roads and walkways should be fine. Bit some areas further to the north and west, as well as sheltered valleys, may have pockets of colder temperatures. In these areas we might see a little bit of freezing rain after the switch-over until the warmer temperatures make it to those areas as well.

I’ll have additional updates as warranted.

Figured tonight would be a good time to repost this graphic that explains the difference between snow, sleet and freezing rain.

And you can only get hail in thunderstorms which are typically in warmer weather. Hail and sleet are different.

So right now, even though we are well below freezing at the surface in western New Jersey (mid 20’s), there is a warmer layer above us that is melting the snow. But there is still enough cold air near the surface to re-freeze the rain and turn it into snow. Once a snow flake melts, it can’t go back to being a snow flake Sad smile

We will most likely have a period of freezing rain until all of the warmer air makes it down to the surface and gives us rain. We want that to be a short as possible. I’d rather have sleet over freezing rain…
