…Mixed rain and snow over the upper Great Lakes tapering off as low
pressure system moves into Canada…
…Rounds of scattered showers and possibly severe thunderstorms develop
over the central Plains beginning later on Tuesday…
A low pressure system tracking across the upper Great Lakes this Monday
afternoon is forecast to move farther into southeastern Canada through the
next couple of days. Mixed rain and wet snow as well as gusty winds
across the upper Great Lakes will gradually taper off this evening.
Showers and thunderstorms associated with the trailing cold front will
sweep across the Northeast through tonight along with gusty winds.
Farther south, only scattered showers are expected to pass through the
Mid-Atlantic tonight. Across the Deep South, showers and thunderstorms
are expected to linger through the next couple of days as the trailing
front stalls across the region. Moisture from the Gulf will then
gradually stream northward into the southern and then the central Plains
through Wednesday as southerly flow strengthens. Rounds of scattered
showers and possibly severe thunderstorms can be expected to develop from
time to time beginning later on Tuesday with increasing frequency going
into Wednesday as a low pressure wave is forecast to develop over the
southern High Plains.
Over the northern Rockies, mountain snow will gradually taper off tonight
as an upper-level trough passes through and heads into the northern
Plains. This trough will then bring a round of rain showers with embedded
thunderstorms tonight into Tuesday across the northern Plains into the
upper Midwest where a weak occluded cyclone passes through. Meanwhile,
much of the Southwest as well as Florida will remain dry through
Wednesday. Temperatures will average above normal across a large portion
of the country while cooler than normal conditions will be confined to the
Pacific Northwest and into the northern Plains.
