...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.
