In the week ahead, an active weather pattern will keep stormy conditions in the Northwest, while the central and eastern U.S. will see warmer temperatures ahead of a system that will move through the Midwest and Northeast Friday into next weekend.

Here are four things you should know going into the new week.

1. Heavy Rain and Snow in the Northwest

A nearby upper-level trough, or southward dip in the jet stream, will keep a parade of low-pressure systems into the Pacific Northwest into next weekend.


This Week's Forecast

The first of these systems will push into the Northwest through Monday, spreading rain and mountain snow across the region.

Strong winds are also expected to accompany this storm, particularly in coastal areas of Oregon and Washington, where there could be some tree damage and localized power outages.

Periods of heavy rain and snow are expected to continue through Thursday in the Northwest, northern Rockies and northern California. Gusty winds are also anticipated.

Through late week, a widespread area of more than 3 inches of rainfall is expected from western Washington into western Oregon and portions of northwest California. Heavy rainfall over several days could bring the concern of flooding in a few areas.


Rainfall and Snowfall Forecast

In addition, several feet of snow are expected in parts of the Cascades and Olympics, adding to the snowpack. Some locations in the northern Rockies and northern Sierra will also see more than a foot of snow.

2. Temperatures Will Moderate in the East

Arctic air brought very cold temperatures to the Midwest and Northeast over the weekend, with numerous record lows broken. International Falls, Minnesota, even set a record Friday for coldest temperature so early in the season with a low of 14 degrees below zero.

High temperatures will return to near average for mid-November early this week. However, low temperatures will be slightly below average in the East through Wednesday morning.


Forecast Highs

A more southerly flow is expected ahead of a low-pressure system late in the week, which will allow temperatures to rise to slightly above average.

3. Warmer Weather to Return

Warmer-than-average temperatures in the Southwest will start the week due to an upper-level ridge of high pressure.

High temperatures as much as 20 degrees warmer than average will spread into the southern and central Rockies and into the central U.S. early this week.


Forecast Highs

This translates to highs in the 60s and 70s as far north as Nebraska, with highs in the 80s in the Desert Southwest.

The mild conditions will slide eastward during the week, allowing Minneapolis to see highs in the mid-40s Monday and Tuesday, instead of highs in the 30s.

Highs will remain 5 to 15 degrees above average through midweek in the central U.S. before the next blast of cold air begins to surge southward into the northern Plains.

4. Late-Week System Will Bring Rain, Snow and Colder Temperatures

An active weather pattern will bring showers and thunderstorms, associated with a low-pressure system moving through southern Canada, to parts of the Midwest and Northeast late Tuesday through Thursday, with snow showers possible in northern New York and northern New England.

Then, another low-pressure system will track eastward into the Plains and will move through the Midwest and East from Friday into next weekend.

Showers and thunderstorms will spread eastward, and some snow is also possible along the Canadian border and into Canada. A snowstorm with wind-driven snow is possible in parts of the Great Lakes snowbelts and the upper Midwest.


Late-Week Setup

Behind this system, chilly temperatures are also expected to return to the Midwest and East.

The details with this system remain uncertain given that it is several days away, so check back frequently for updates.

Half of the village of Big Sur, on the coast of central California, has lost its only access to the north following the demolition of the flood-damaged Pfeiffer Canyon Bridge along State Route 1 (also Rt. 1 or SR 1) on March 19. Although Rt. 1 to the south of Big Sur has reopened to traffic (after mud and rock slides were cleared) it is a long 70-mile journey along the windy but spectacular highway to Cambria, the next town of any significance where supplies can be had. CalTrans (California Department of Transportation) estimates it will take 6-9 months to rebuild a new bridge over the canyon.

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
