Greenwich Twp Snow Photos January 27 2015

We all woke up Tuesday morning to about 3” of snow in western New Jersey give or take. So what happened? There is a storm and some areas got hit hard: Long Island, CT even NYC somewhat.

So what happened? Once the coastal storm formed and started strengthening it was about 50 miles or so further East than expected. This didn’t allow most of NJ to get into the heavy snow. The snow we did receive was during the day Monday from the initial clipper storm itself.

My theory on what helped this is as follows: Central PA received more snow from the clipper than forecasted. State College received a foot of snow! From a clipper? State College is certainly too far inland to be impacted from a coastal storm. I believe some energy remained over central PA. This combined with the rapidly developing storm over the ocean resulted in a snow “hole.” What I mean by this snow hole is as follows. Rising air is what causes clouds that ultimately turn into precipitation (very simplified). But you can’t have rising air everywhere. Someplace has to see sinking air. When air sinks is dries out and hence no or lighter precipitation. This is a common occurrence in these type of clipper storm that suddenly intensify when hitting the ocean. This was in part why I was keeping my snow totals much lower than most – even lower than the NWS.

I saw the signs late yesterday but I didn’t want to change thinking there was a chance. But the chance is gone. We will see breezy conditions develop today as the storm pulls away. We will see occasional snow showers that could result in a small additional accumulation.

Cold weather will continue all of this week – be prepared for that. Then ANOTHER clipper will move through the area fast on Thursday night into Friday morning. Don’t worry this won’t won’t be intensifying since it will be further to the North. But these types of storms, as we have seen already this winter, can drop nuisance snows.

I wanted to post one more update before retiring for the evening. So far western new jersey has picked up about 3” of snow. Currently it is not snowing that much in western new jersey. All of the heavy snow is east of us in NYC and Long Island. BUT it is heading this way!

The storm is having a hard time getting the snow to move west. So we may be looking at the lower end of my original forecast of 6-12” The updated NWS graphic above is closer to reality. Since we already have 3” on the ground would only need another 3” to meet the minimum range.

We have always said the heaviest part of this storm would be overnight. I have remembered several storms where it didn’t “look good” before I went to be but then woke up in the morning to witness all the snow. Not saying that will be the case this time but not willing to lower my totals at this time.

In looking at weather data so far, I’m impressed with the storm and starting to worry that perhaps this is an over achiever for western New Jersey.

On the radar above that was taken at 2:30 pm on Monday, there is now a solid band of snow over Long Island across NYC into northern NJ. This has formed faster than I anticipated. Furthermore the band appears to be staying in place. I’m starting to wonder if this band will remain and pivot as time goes on and the storm gets closer.

Computer models continue to support the storm as is. Current observations are showing the storm has formed slightly WSW of where the computer forecasts indicated. Furthermore the upper air support may be slight more favorable as well.

The NWS snowfall prediction from mid day is above. They are forecasting 10-14 for western New Jersey which is slightly higher than my forecast. They released a statement that a new snowfall forecast map will be released at 4pm. It will be interesting to see if there are any changes.

We also received 1.6” of new snow as of lunch time. This was a little more than what I though we would receive so early in the storm cycle.

So as of right now I continue to support the totals show in the map above. If I continue to see signals I’m seeing now I may be increasing my totals later on. I don’t like to do that but don’t want to leave anyone “buried” if there is a change in the weather.

Beyond this storm we will remain in an active pattern. Look for another fast moving clipper snow storm Thursday evening and night. This certainly won’t be anything impressive but will add to the cold and snow totals. There are also signs of a larger storm towards Ground Hog day…

Here is a great graphic from NWS Boston showing the different types of winter precipitation and how each type forms.

The only thing I’d like to point out here is it RARELY hails in the winter time. I hear a lot of folks saying “it’s hailing outside” when it’s really sleeting. Hail is found only in thunderstorm type of clouds with strong updrafts. Yes this can happen in the cold season but it’s rare.
