Added the Green Bank Observatory to the list. I know little about the station. Radiation shield, siting , etc. A Cass station ran 32 and 82 today, seeing the similarity gives me some confidence in its accuracy.

  Frost this a.m was reserved for the valleys only and freezes only for the coldest spots. Temps jumped greatly across the high ground. At 7 a.m this morning, The Glades were at 27° after a 26° low, while at 7a.m the Garrett Airport reported 54° and Keysers Ridge highway station at 219 ran 58° . A 31° spread.  Similar elsewhere. Green Bank low 30s, Silver Creek at Snowshoe 57° at 7a.m. Blackwater station in Davis at 30° while Cabin Mt ran low 50s.  Typical of the air mass for the time of year. Dominant ridge with a HP north. Dry air, low dewpoints. Long nights allow for some impressive temp falls in the valleys while mixing keeps high ground much milder.

 Beautiful day with wall to wall sunshine.

 Interesting note and not unusual the valleys have the greatest temp spread, but today Mt tops rose 15-20° today as valleys rose 35-50°!
