Much Colder Weather Returns ! Some Light Snow or Flurries Possible This Weekend, Mainly For Parts of VA.

The colder weather is here to stay well into next week. A strong cold front moved through the region today, which brought some heavy rain and strong gusty winds. Behind this front, much cold air will continue to filter into the Delaware Valley and The M/A States and will be with us for quite a while.

Partly Cloudy and cold weather will be the rule for Thursday through Saturday. Highs will be in the low to mid 40's and lows in the Upper 20's to low 30's. As we get into the weekend things start to get interesting. A downstream shortwave develops on the trough over the Plains and lower Midwest on Friday and Saturday. This then sparks a weak surface low over the lower Ohio Valley on Saturday. This disturbance will then move east to the NC Coast on Sunday.

Some light snow and flurries will break out from Northern NC and much of VA later Saturday into Saturday night. Depending on the track and strength of this disturbance and vort energy aloft with the s/w(shortwave), will determine if parts of the Delaware Valley see a period of light snow or flurries. This would most likely occur later Saturday night into early Sunday for areas near and south of PHL.

So, at this time I'm thinking Southern NJ and DE will have the best shot at seeing a touch of snow or flurries. I'll keep a close eye on this potential, and will update on Friday evening with a more solid call and better details. No accumulation for SJ and DE, but some light accumulations are possible for parts of VA.

The cold weather continues into early next week but no real threat of any snow during this timeframe. Highs will only reach the Upper 30's for both Monday and Tuesday, with overnight lows in the mid to upper 20's.

Take Care,
Ruggie
