Here Comes The Cold

With the most recent snow event past most areas picked up around 3"-5" and less than that as you head south and east. Snow depths across the area have a high liquid content and this plays an important role in forecasting the temperatures over the next week or so. First off let's take a look at the current snow depths:
The highlands region has around 1"-2" of liquid water trapped in the snow cover while areas with the fresh snow have less than 0.5". The snow in those locations will melt over the next few days and will affect the temperatures. With minimal to no melting in the northern areas the daytime temperatures will be a good 10-15 degrees cooler than the areas without bare ground when the arctic blasts begin to move in this week. This cold be some of the coldest air to invade the northeast in years but New Jersey is on the southern edge of these air masses and should be spared the worst.

Let's take a look at a model for our first shot coming Wednesday:

The heart of the polar vortex will sitting just to the north of New England and this will deflect any chance of significant northeast snowstorms all of next week. Places in the north country of NY and VT will see the temperatures drop to 20-25 degrees below ZERO. New Jersey on the other hand will have it easy with single digits for the areas with snow cover (teens other wise). This type of pattern is good for resorts that need to make snow, but not for powder hounds. The shots of cold air will come in waves through the week keeping us under blue skies and chilly temps.

For now it's typical January weather and for those of you who like ice fishing you'll be on the ice by next weekend!

Lake Musconetcong on the border of Morris/Sussex counties is completely frozen. All it needs is a few cold nights and it will be ready.

By January 8th the pattern will break to one more that gives us an actual shot at seeing our next precipitation event, whether that be rain or snow. For the next few days just try and stay warm!
