Rumors of a Snowpocalypse 2014 this Weekend

12z GFS Ensembles (Shows the extent of Uncertainty in Placement of the Low Pressure)

 GFS Model Ensembles currently show high uncertainty in placement of the low pressure this weekend.

After what turned out to be a bust for the immediate Washington Area (sorry kids) what does the weekend hold? There are lots of rumors going around of an east coast blizzard impacting the Mid-Atlantic this weekend with words like “Snowpocalypse 2014”.

Temperatures will begin to cool off across the Mid-Atlantic states as high temperatures drop back down to below seasonal levels. While it won’t be as bitterly cold, highs will drop back into the 30s for much of the Region throughout the upcoming week with lows back in the 10s and 20s.

The medium range models are now showing signs of a potential coastal storm that may form along the Gulf coast and then either move up the spine of the Appalachians with a secondary coastal low developing (snow to a mix back to snow), or a classic Nor’easter that “bombs” out off of North Carolina’s Outer Banks dropping feet of snow on our area.

Either solution is possible and this system will be watched closely.  Yes, another juicy storm is heading our way, one which could deliver several inches or feet of snow.  Before anyone gets excited, remember this system could also track west of us producing a few inches of snow and then much of the region could change over to a mix of ice or rain.   One thing is for sure, I will be watching the NAO index like a hawk, as there are now signs that it is moving towards neutral. If the NAO starts to move into negative territory… the rumors floating around may hold some water.

    That situation yesterday was depressing! I knew we were in trouble when little by little the models kept getting warmer with time.

    The models are all over the board for this weekend situation. GFS has a Miller B situation with us getting minimal amounts, but the Northeast getting slammed. Euro and Canadian had relatively weak storms. I suppose the models will do their normal hopping around until a day or two before the storm.

    I recall the DC snowpocaypse predictions not looking optimistic just 4 days prior to the storm (Capital Weather Gang had low confidence of a snow event), should be interesting to see what happens with this one.
