Interesting that NWS keeps mentioning the NAM MOS for suggesting temps will only rise 7-9 degrees on a strongly advective S/W wind. However. the latest NAM OP guidance jumped ship and changed the high at MDT from 66 to 73. Even with a mostly cloudy day (which is also questionable) I think temps rise 12-15 degrees from their current position. If we do get quite a bit of sun, then 80's are possible. Monday keeps looking less and less record setting though. Euro has in the 40's late next weekend.
