...Widespread rain and high elevation snow expected across the Pacific
Northwest and Northern/Central Rockies through mid-week...

...Cooler temperatures will arrive in the West by mid-week while the
Central U.S. warms...

The low pressure system that brought severe weather to the central Gulf
Coast yesterday is slowly moving northeast. The system is forecast to
split into two weaker low pressure systems on Monday as it approaches the
East Coast. Unsettled weather will gradually spread eastwards across the
eastern U.S. as the system progresses, but severe weather is not
anticipated. Trick-or-Treaters in the Ohio Valley, central and southern
Appalachians, Mid-Atlantic, and portions of the Southeast may have to
dodge showers and isolated thunderstorms. This system is expected to push
offshore into the Atlantic on Tuesday and the eastern U.S. will become
mostly dry by Wednesday. A separate low pressure system just south of the
U.S. will also bring scattered showers and thunderstorms to South Texas
and portions of west and central Texas Monday through Tuesday.
Precipitation chances will diminish in Texas on Wednesday.

Trick-or-Treaters in the Pacific Northwest will likely have a soggy
Halloween on Monday as a cold front moves southeast across the region.
Widespread rain at low elevations and mixed precipitation and snow at high
elevation will develop behind the front, engulfing the region and
spreading into the northern and central Rocky mountains by Tuesday. Rain
and high elevation snow will remain in the forecast for these areas
through mid-week with isolated heavy mountain snow possible at times.
Precipitation will start to push into the central U.S. later this week
when the front moves past the mountains.

Colder air will filter in behind the front, and below normal temperatures
are forecast to spread across most of the western U.S. by mid-week. High
temperatures in the 40s and 50s will be common, and high elevations will
be colder. While the west cools, southerly flow ahead of the system will
bring warmer air into the central U.S. Temperatures will be above average
through mid-week for most of the Central U.S. with highs in the 60s and
70s.
