Bolaris: Flaky weekend and Polar Vortex ahead

Your Friday will be fine as any early morning cloudiness will give way to sunshine and temperatures will be above average for this time of the year - with highs in the mid-40s.

A modified arctic front will approach late Friday night into early Saturday morning with just a few snow showers or flurries, with only a coating possible on grassy surfaces north and west of town. Temperatures will be quite a bit colder with highs in the mid to upper 30s.

Your Saturday plans should go off without a weather hitch.

After midnight Saturday and into Sunday morning another shortwave (mini upper level storm) will dive south and east with another chance of a few snow showers or flurries. Sun will return by midday Sunday and temperatures will be within a degree or two of 40.

Martin Luther King Day looks, by January standards, great with a decent amount of sunshine and temperatures in the lower 40s. 

A poke of the Polar Vortex (think of it as a large-scale spinning mountain of frigid air) will drop south across southeastern Canada and send another polar package our way for Tuesday through Thursday, with the core of the polar dome to be felt on Wednesday as temperatures struggle by day to crack 20 degrees and once again dropping into the single digits by night. 

As far as accumulating snow potentials, I will keep it as a low-level threat (30 percent chance) through Thursday with snow showers or flurries the main threat.

But accumulating snow potential may increase some by next weekend as we stand a better chance of more significant coastal development.

The jet stream is traveling at warp speeds so computer models will have a difficult time handling any medium range projections. The trends of late have been to keep storms offshore with minimal impact for the East Coast.

Three big events are coming up as we close out January and move into February, The first, the 22nd anniversary of Wing Bowl, a day of debauchery and Philadelphia's version of Mardi Gras. The brainstorm or mind burp of WIP's Al Morganti (Jan 31 at Wells Fargo).

Howard Stern's birthday bash is on for Jan. 31.

And, of course, the Super Bowl on Feb. 2.

I will be following all three and keeping you posted on what to expect weather-wise.

Farmers Almanac is predicting a snowstorm for the bug game in East Rutherford, N.J. I will be taking a closer look at the Super Bowl outlook next week.
