...Upper-level low to produce snow and rain showers over parts of the
Great Lakes, Ohio Valley and interior Northeast through Sunday...

...There is a Critical Risk of fire weather over parts of the
Central/Southern Plains through early next week...

...Heavy snow for the Cascades...

A deep upper-level low will push off into the western Atlantic this
weekend, putting an end to a period of sustained light precipitation
across the Great Lakes and Northeast. Light rain, scattered to isolated
thunderstorms and snow showers are likely to persist across the Great
Lakes, Ohio Valley and interior Northeast today before winding down on
Sunday. Cool air will filter into the eastern half of the country on the
backside of the associated surface cold front through Sunday.

Another deep upper trough centered over central Canada will eject a pair
of surface low pressure systems into the Great Plains today. Some light
rain/snow showers and thunderstorms are possible along the Front Range
through Sunday. By Sunday night the more southern system will arrive over
the Midwest, bringing with it the chance for additional thunderstorm
activity. The threat of severe weather remains marginal for the midsection
of the country this weekend. Warm air will ride out ahead of this system
and spread from the Great Plains on Saturday to the Mississippi Valley on
Sunday. A colder airmass will settle over the Northwest this weekend as
the aforementioned cold front sweeps through the Rockies today.

A sustained period of moderate to heavy rainfall and heavy mountain snow
are set to ensue over the Pacific Northwest this weekend as onshore flow
and a subsequent shortwave pull moisture into the region. Some scattered
to isolated thunderstorms are possible over parts of the coastal and
inland Pacific Northwest today. Light to moderate snowfall is also
expected over parts of the Northern Rockies through the Weekend. The
Cascades will experience a weekend of heavy snow with accumulations of 1-2
feet likely. A deep low pressure system is forecast to arrive over the
Pacific Northwest by Monday morning. This system is forecast to carry a
substantial amount of Pacific moisture, but there is some lingering
uncertainty with respect to its timing and track at the moment.
