Tuesday afternoon winter storm update for NJ metro

Latest post: 4:50pm -- 2/11/2014

Tonight remains clear. It will be very cold. Lows drop into the single digits and teens, with some below-zero readings possible, particularly for northeast sections of New Jersey.

Wednesday is expected to see sun followed by increasing clouds.
Highs reach the mid- to upper 20s once again.

***A nor'easter is highly likely for our area ***
*** The track remains uncertain on Thursday ***

Snow will arrive between 11pm and midnight in southern NJ Wednesday night, and around 1am - 2am early Thursday morning for the rest of the Garden state, New York City, and Long Island.

Snow should continue for much of the area through the Thursday morning commute.

Based on the last 2 models ... it looks like a change to rain is becoming more likely ... around 6 - 7am for southern NJ, and during the mid- morning ( 9- 10am Thursday) for central NJ, NYC and Long Island.
Before this change-over, 4 - 6 inches is likely for the above-mentioned area... with 8 - 10 inches for northwestern NJ, as the change to sleet and rain will take until Noon or 1pm...

This is still not etched in stone, as there is one other model, the "NAM" model, which only changes the snow over to rain for extreme southern New Jersey...
If this model verifies, the snow totals mentioned above can become 8 - 12 for just about the entire region.

Stay tuned.

Monday afternoon winter storm update for NJ metro

Latest post: 5:10pm -- 2/10/2014

Dry and cold weather continues through Wednesday...

Clear skies are expected tonight. Low temperatures drop into the single digits for the northern and western NJ, as well as parts of Long Island, to the teens in the rest of the Garden state and New York City.

Tuesday is expected to be another mainly sunny day. Temperatures top out in the mid- to upper 20s.
Night-time readings fall into the single digits and teens.

Wednesday will see increasing clouds, with highs, once again, in the 20s.

*** High confidence of a nor'easter to impact the NJ metro area late Wednesday night through Thursday**

Differences in the models remain, keeping snowfall predictions at average, to below average certainty...

Snow is likely to arrive between 11pm Wednesday and midnight Thursday for southern NJ, spreading northward into the rest of the Garden state, New York City, and Long Island between 1am - 2am Thursday...
Snow will continue through at least the morning commute for just about the entire area, with the exception being extreme southern NJ...

Three tracks are currently being depicted by the models:

1) A track that means a changeover to rain for nearly the entire area by mid-morning Thursday
2) A track that would bring heavy snow to the entire region.
3) A track resulting in all snow, but not as significant

Future data will determine the outcome, and tonight's model run should begin to minimize the models' differences...

Monday night weather update for NJ metro

Latest post: 11:40pm -- 2/3/2014

After a snowy Monday -- we will enjoy a quick break in the stormy weather ...

Tonight is expected to be mainly clear -- with lows in the mid- teens on Long Island, and in northwestern New Jersey, to the lower and mid- 20s for the rest of the Garden state and New York City.

Tuesday will feature partly sunny skies, with highs in the lower to mid- 30s.


Precipitation arrives between midnight and 1am Wednesday... in the form of snow... and continues as snow until around 4am for southern NJ, 5am for central NJ NYC and Long Island, and until 9am for northern and northwestern parts of the Garden state.

Accumulations will range from 1 - 2 inches for southern NJ, 2 - 4 inches for central NJ, NYC and Long Island, to 3 - 5 inches for northern and northwestern sections of the Garden state.

** Freezing rain looks to be a moderate concern especially for west/central and northern NJ, NYC, and western Long Island (Nassau county). **
Two - three hours of freezing rain is possible, mainly from 9am - noon for the above-mentioned areas.
This can cause power outages.

A change to plain rain is forecast for most to all areas between 11am -- 1pm.

Rain may end as snow again between 2 - 3pm for central and northern New Jersey/ NYC and Long Island.
Highs on Wednesday will range from the lower to mod- 30s up north, to the lower 40s in southern New Jersey.

This is a very complex storm, with snow amounts and precipitation types/timing...
I will try to pinpoint these details better as more data arrives on Tuesday.

Prepare for delays and difficult travel on Wednesday, both into work, and on your way home...

The storm leaves late Wednesday afternoon.

Thursday, Friday and Saturday, to begin the weekend, return to dry weather, with cold temperatures. Highs in the upper 20s to lower 30s. Lows drop into the teens to around 20 degrees.

Rain or snow is possible later Sunday into Monday.
More details on this potential storm in the coming days.

Snowfall update for NJ metro

Updated: 11:15am -- 2/3/2014

Thinking the highest chance for 6 - 10 inches will be in central New Jersey -- eastward into NYC ...

Most other areas will average out between 4 - 6 inches for Long Island and south-central New Jersey...

See how much snow your county will get in the ​​​​map below...

Already seeing signs of any icy start with the next storm on Wednesday...
Details on this soon.​​​

Monday morning winter storm update for NJ metro

Winter storm update: (7am -- 2/3/2014)
Temperatures dropped overnight into the 30s, and are currently between 32- 37 as of 7am.
Central and northern NJ, NYC, and Long Island have seen snow for the past few hours, while southern parts of the Garden state are experiencing rain...

Taking a look at some data, the NAM model has remained consisted with the increase in the moisture availability with this storm from last-night...

Based on recent temperatures trends, radar imagery and other model consensus with higher snowfall output, mentioned in my last post late last-night -- accumulation totals will range from 6 - 10 inches for the entire area.
Secondary streets will be a challenge, and become very slippery.

Main roads/ highways should be less impacted, and will be slushy, but somewhat difficult to drive on.

More details soon.

More weather data, more moisture

Posted 12:10am -- 2/3/2014

Took a look at some more data...
Moisture availability continues to be increased by the weather models with this storm...
The temperatures around 7am Monday will be crucial....

If we are at, or below freezing, then many areas can easily see 6 - 10 inches -- primarily on grassy areas, and non-paved/ colder surfaces/ car tops, etc.
