There is no denying how the computer guidance has been trending over the last couple of model runs. A secondary storm on Sunday develops well within our storm window. Cold air is crashing into the state at the same time and the end result will be snow. How much? We are still ironing out details, but I feel confident in the forecast with the information we have at hand that it will be shove-able. It will be plowable in spots. It won't be crippling, but with Monday being a holiday, even the hardest-hit neighborhoods will have an easier time cleaning up.

Let’s not get into the meteorological nitty-gritty just yet. Let's just focus on what you need to know.

When does the snow start?

Light snow begins in southern New Jersey around 8 a m. Sunday. The snow will slowly sweep northward through the day. The worst of the storm will ramp up around 4, 5 or 6 p.m. Two inches of snow an hour is possible.

Snow will collect very quickly. Roads will be covered and slippery. Road crews, with that kind of intensity to the storm, won't be able to keep up with accumulations. So I think a few passes with the plows will be needed. The snow finally begins to taper around 9 p.m. or 10 p.m. A sizeable amount of snow is likely in some neighborhoods.

After the snow, dangerous cold quickly moves in on gusty winds. Temperatures will be in the single digits to near zero on Tuesday, Wednesday and Thursday mornings. The wind will make it feel like -5 to -15 below zero. Daytime highs will be in the upper teens with windchills that will feel like the single digits.

Frigid might not be the right word to describe the cold next week. People will feel disrespected by Mother Nature if they have to spend any time outside. This is a ferocious, savage, unmerciful airmass that will be with us for a while next week. Be prepared for higher-than-normal energy bills the following month. Hopefully your home's pipes don't freeze up, expand and burst. This is the type of cold that can easily do that.
