After a period of quiet weather, precipitation chances will increase
Friday and on into the weekend, as a system passes just south of the
area and a northern stream trough shifts into the region. With only
a limited amount of cold air tapped from Canada, precipitation will
fall as a mix of rain/snow during this period as temperatures
oscillate through the 30s during the diurnal cycle. Based on model
consensus in the track of this system, modest precipitation amounts
look plausible with this system, especially in the Friday night to
Saturday time frame as the upper low passes to the south and some
degree of deformation sets up in the vicinity. The ECMWF remains
alone in a track farther to the south which would mean a bit more
colder air would sneak in allowing for a better chance of
precipitation falling as all wet snow at times. However, this could
all change given the temperature and track uncertainty.
