    March 7-8 possible snow threat

    NWS Honking “915 pm UPDATE: Dangerous wet snow storm on its way! NO CHANGE IN SNOW AMOUNTS BUT HIGHER AMOUNTS POSSIBLE AT 4 am. No unnecessary travel is recommended by the NWS after 7am Wednesday. This is going to be a very high impact storm with widespread power outages "probable". Give us time to digest the new model guidance. The map posted is a minimum expectation. Also circled is the probable area of widespread power outages in our forecast area.... and we may need to expand this southeast to near Philadelphia at 4 AM. Please add your snow amounts here. We'll monitor through the night. Thank you!”

    Large area of low pressure moving out of that region causing pressures to rise dramatically, not necessarily a strengthening anticyclone unfortunately.

    For anyone that would like to believe the 24hr 11z ruc, we are very much in the game. 5H heights aren't quite as suppressive as the nam or gfs show. Has 3-4 inches of snow overspreading sepa by 6 am tomorrow.

    Exactly, I'm very surprised the qpf field did not respond to that.
