Forecast BUFKIT profiles
suggest precipitation onset as all snow; and with sufficient moisture
through the DGZ, a few inches snow may accumulate which may pose
hazardous travel conditions during the morning commute. Though,
efficient snowfall accumulation potential should be short-lived with
the infiltration of mid-level dry air.
Nevertheless, recent GFS analogs suggest the greatest potential for
2 inches or greater exists for the I-80 corridor and higher
elevations, and 4 inches or greater for the highest elevations in WV.
To address this potential advisory-level criteria, these counties
have been highlighted in the HWO. Guidance suggests a precipitation
changeover should occur for lower elevations, including the PGH
metro, as veering low level southerly flow ushers in warm enough
conditions to support rain. A cold front passage Monday afternoon
should diminish remaining precipitation potential through Monday
night, with lingering low level moisture beneath a subsidence
inversion maintaining mention of flurries.
