Windy today and cooler tomorrow, weekend looks seasonable

Today we will continue to clear out as a dynamic shortwave trough moves out of the Northeast US.  Thunderstorms erupted over western Maryland and the DC region last night.  This front moved through late this morning.  Clearing will continue along with the windier conditions today through tonight, before subsiding tomorrow before another clipper  moves by to the north of the region.  The advertised potential coastal storm for Friday is no longer, upstream ridging pattern is not going to cooperate for us.  I am eyeing the 26-29th for a potential stormy period.  00z GFS and 12z GFS both hinting at a big snowstorm potentially for the interior region and rain/snow for the coastal plain.  However models are very unsure what is going to happen beyond 5 days.  A short reprieve from the colder air arrives Monday/Tuesday before a front moves through the region sometime Tuesday night into Wednesday morning ushering potentially a colder air mass into the region.  Right now weather should remain quiet for the weekend.  I will have another update tonight.
