I'm going to see accumulating snow, I already know.
MQT:
Core of the coldest air will drop across the area on Fri. As an indication of how anomalously cold it will be, the NAEFS and ECMWF ensembles indicate 850mb temps falling to around -12C on Fri which will be outside the 1979-2009 climatology for this time of year, or stated in another way, none of the reanalsyses btwn 1979 and 2009 for this time of year showed 850mb temps as low as currently fcst. As for pcpn, expect little if any until Thu night/Fri when the coldest air arrives. It`s extremely unusual to see LES in May, but if the degree of cold verifys along with the shortwave swinging across the area, there will be some lake enhanced snow or at least a springtime hybrid type LES where land based instability supports further development inland downwind of the lake.
