    Mesoscale Discussion 0006
    NWS Storm Prediction Center Norman OK
    1047 AM CST Sat Jan 06 2024

    Areas affected...Central/Southern PA...Eastern WV
    Panhandle...Western/Central MD...Far Northern VA

    Concerning...Heavy snow 

    Valid 061647Z - 062145Z

    SUMMARY...Snowfall rates are expected to increase across the region over the next several hours. Rates around 1"/hr are likely across much of the area, with localized 2"/hr rate possible, particularly across south-central PA. 

    DISCUSSION...Recent satellite imagery shows a low-amplitude shortwave trough over eastern TN, moving quickly northeastward. Regional radar imagery shows a large area of precipitation across the Mid-Atlantic and into southern portions of the Northeast, within the warm conveyor preceding this shortwave. Attendant low-level flow is forecast to strengthen over the next several hours as the shortwave continues northeastward. Additionally, the attendant surface low, which is currently over south-central NC, is expected to deepen over the next few hours as it moves northeastward across central NC and southeast VA. 

    These factors will result in an area of strong low-level frontogenesis over VA, with associated lift focused into central/southern PA, the eastern WV Panhandle, western/central MD, and far northern VA. Most of this area is currently experiencing moderate snow, but snowfall rates are expected to increase over the next few hours as the evolution described above occurs. Rates around 1"/hr are likely across much of the area, with some areas experiencing 2"/hr, particularly south-central PA where banding appears most likely. Highest rates are expected to be centered around 20Z, with rates then likely diminishing over this area as the shortwave continues northeastward.

    I’m not staying up for the 0z runs tonight. I’m going to wake up in the morning and just look at Amwx subs to see how many (or not) pages have been added prior to looking at the runs early tomorrow AM. I’ll know if it’s good or bad off that alone.

    Nice play !
