...Unsettled weather for the Northwest & Northern California, with an
increasing threat for heavy rain for both areas today into Wednesday...

...Strong winds for coastal sections of northern California late Tuesday
into Wednesday...

Zonal, or west-to-east, flow is expected across the Lower 48 over the next
few days. This will maintain above to well above average temperatures
across large swaths the country.  This also favors wetness/periodic
storminess for the Northwest/Northern California due to onshore flow from
the Pacific and dryness due to downslope flow across the High
Plains/Plains.  Any precipitation for the Great Lakes and East should be
modest in amounts.

The wetness across the Northwest, with mountain snows farther inland
across the Northern Continental Divide which have prompted winter weather
advisories, will be initially caused by a weakening low moving into the
Oregon interior and its trailing front wavering near the coast from
Northern California northward, keeping rain in the forecast.  Late this
morning into Wednesday, a strong cyclone in the northeast Pacific
reinforces the existing front and causes breezy to windy conditions to
renew from northern California northward and brings the potential for
heavier rains within the system's atmospheric river; isolated to widely
scattered thunderstorms are anticipated.

Downslope flow in the High Plains promises breezy and dry conditions.
Today, portions of Wyoming, far southwest South Dakota, far northeast
Colorado, and western Nebraska continue have some potential for wildfire
risk due to the continued dry air mass and breezy conditions; red flag
warnings are in effect for portions of western Nebraska.  Record high
temperatures are possible for portions of the Texas Panhandle and the
Colorado Front Range today due to the compressional heating afforded by
the downslope flow.

Skirmishes of showers are expected with a progressive low pressure area
late today through Wednesday across the Great Lakes/New York/New England. 
Higher elevation snow showers are anticipated for the Northern
Appalachians in the wake of frontal passages this morning and then again
on Thursday morning.
