...A cold front will move across the Mississippi Valley and southward
through the Plains, bringing rain chances across the Midwest on Saturday
and across the Tennessee Valley to Texas on Sunday...

...Rain to persist over the Pacific Northwest for the weekend...

...Above average warmth and dry conditions will build in across the West
as ridging builds across the region...

An intense cyclone approaching October low pressure records for New
England will continue to move away from the New England region today.
However, the storm system may yet bring some tricks for those on Halloween
night. Strong winds will be howling like a werewolf across most of the
Northeast, with gusts in the 40-50 mph range possible and reaching Wind
Advisory criteria. Furthermore, it will be a frightening chilly night
across the Southeast as cold air advection continues to funnel down behind
the front. Low temperatures in the middle 30s will be possible across most
of the East Coast and as far south as northern Florida. Freeze Warnings
and Frost Advisories are in effect across areas in the South. Low
temperatures should modify slightly for Sunday and Monday mornings across
the East, but staying seasonably cool in the low 40s and some upper 30s.
High temperatures should be slightly below average with the afternoon
mercury hitting the 50s and 60s. As for precipitation, a weak cold front
looks to bring chances for rain across the Midwest tomorrow and then
across the Tennessee Valley into the Carolinas on Sunday.

The Pacific Northwest will see the heaviest precipitation across the
country as an atmospheric river and cold front move ashore the Washington
and Oregon coastlines tonight. The coastal zones may see rainfall
accumulations in the 2-3 inch range and as much as 3-5 inches in the
Cascades and Olympic mountain ranges, prompting an isolated risk of flash
flooding and perhaps some river flooding. Additionally, gusty winds and
high waves are hazards with this storm system. Elevation snow in the
Cascades is also likely into Saturday. The local offices do not have Watch
and Warning hazards as of this afternoon. A reinforcing disturbance will
bring additional rain showers into Sunday and eventually push a cold front
through the Northwest.

Central and southern portions of the Intermountain West should remain
seasonably warm and dry with high temperatures in the 70s commonplace.
Southern California and Arizona may approach the 80s and low 90s. On
Sunday, the warmth will shift westward across the Rockies and into the
Dakotas. High temperatures are likely to hit the upper 70s across the
Front Range, which is about 10-15 degrees above average for this time of
the year. Low temperatures are likely to still drop into the 30s in the
mountains, but the valleys may have morning temperatures in the 40s, also
well above average for early November.

Last but not least, for those who celebrate, Happy Halloween !
