eep trough over the eastern CONUS will have a series of stronger
embedded shortwaves as it builds S. First in the series will feature
heights as low as 534 dm, or about 3-5 sigma below climatology!
upper level disturbance will also feature quite the cold pool
with 850mb temps around 0C. In terms of sensible weather,
Saturday will be quite a cold and raw day with highs in the
upper 40s to low 50s for much of the interior. Some guidance
including the NAM even shows a non-zero chance for a few
snowflakes under heavier precip in the Worcester Hills and
Berkshires. Any wintry precipitation would be confined to the
coldest part of the cold pool and with heavier precipitation
rates. In short, this will not be widespread wintry event.
