Sunday Morning Technical Discussion

Synopsis: Clouds along the Turnpike associated with a Southern Mid-Atlantic Storm.  This storm will not affect the state in any shape except for some clouds.  The rest of the Commonwealth is being dominated by strong high pressure in Central Canada.  This high pressure will dominate into the work week before moving off the coast of Nova Scotia.  In the wake of the departing high pressure, a storm system will try to affect us on Wednesday with snow shower in the AM, and showers in the PM, but for the most part will remain south of us.  Another storm system will try to take aim at us for Friday, but we will be spared in terms of a "direct hit".


Short term: Both the NAM and GFS both show mostly sunny/partly cloudy conditions for Sunday and into Monday.  They have their solution of where the clouds will be, but went on a compromise that the whole Commonwealth will see partly cloudy skies during this period.


Long term: Continuing from the short term, Tuesday looks to be another day of partly cloudy skies.  Only exception is that a storm system is taking aim at us for Wednesday.  The NAM looks to be faster than the GFS in terms of progression and precipitation.  The NAM has precipitation on the door steps of the state by 8am Wednesday, while the GFS lags behind for a 6-12hours.  For some odd reason, the GFS wants to stall the storm for 6 hours.  The SREF shows that we will mostly snow in the morning of Wednesday, and the GFS hints at AM snow becoming PM rain showers.  So went with the NAM progression over the GFS, but a combo in terms of what will fall from the sky.  The GFS as we progress into Thursday shows clearing conditions before our next system makes a run at us for Friday.  Hint for Friday the 0z shows the majority of the storm should be on the rainy side except at the very end and that a shot of cooler air will be with us for that weekend.
