...Interesting weather pattern for mid-March with winter storm for the
East Coast on Tuesday...
Even though the calendar now indicates March, it is certainly feeling like
winter across much of the country. A huge surface high pressure ridge
over Canada is sprawling southward into the central and eastern U.S.,
allowing for a continuous supply of January-like temperatures through the
rest of the weekend and into the beginning of the work week. This weather
pattern is also setting the stage for wintry weather from the northern
Plains to the East Coast.
Things get interesting for the East Coast beginning Monday night. A low
pressure system crossing the Midwest states is expected to phase with
another low off the southeast U.S. coast. This will allow for a strong
nor'easter to develop near the coast and cause a late-season snowstorm
from the central Appalachians to New England, including many of the big
cities in the Northeast U.S. Winter storm watches and even blizzard
watches are now in effect for the increasing likelihood of significant
snowfall accumulations, with some areas possibly getting in excess of a
foot. There is still some uncertainty with respect to the track of the
low and the axis of heaviest snowfall, and these details will come into
better focus over the next day or so.
Elsewhere across the continental U.S., expect warm conditions to continue
across the southwestern U.S. with no rain or snow in the forecast. The
lower elevations of the Desert Southwest could even reach the lower 90s
for highs over the next few days with an upper level ridge in place.
Onshore flow across the Pacific Northwest will keep scattered showers
around, with snow in the Cascades and northern Rockies.
