Four Things to Know About This Week's Weather
Published: February 12, 2018
Big changes in the weather are ahead for parts of the U.S. heading into mid-February.
A shift in the jet stream will initiate several differences in the weather. Much of the Midwest and East will get a break from the recent rounds of rain and snow while some much-needed precipitation will return to the Southwest.
Below, we highlight four things to watch in the week ahead.
1. Early-Week Wintry System
A weather system that slid into the Pacific Northwest on Sunday will spread snow into parts of the Rockies and the Sierra Nevada through Monday.

Snowfall totals are generally expected to be light, with less than 6 inches of snow anticipated.
Even light snowfall amounts are welcome, as snowfall has been lacking from Oregon into California and eastward into the Colorado Rockies.
2. Moisture Returns to the Southwest
The system that has moved into the Northwest is also good news for Southern California and the Southwest. The recent weather pattern has resulted in a ridge of high pressure over the Southwest, resulting in dry weather and record-warm temperatures.
That area of low pressure will bring a cooler and wetter weather pattern to the Southwest into midweek. Mainly light rain and mountain snow are expected through Tuesday in the Southwest.
Late Week Forecast
A bigger slug of moisture will then push into the Southwest Wednesday through Thursday, producing even more rain and mountain snow.
Rainfall totals will likely be less than an inch for most locations, so it won't help the drought situation much.
3. Wet Weather Continues in the South
Periods of showers will continue in the South this week following this past weekend's heavy rains.
Showers will affect the Southeast and Gulf Coast Monday-Tuesday. The chance for rain could become more widespread Wednesday from the lower Mississippi Valley into the Tennessee Valley.
A cold front will bring even more rain to the South as we head into late week.
4. Colder Temperatures, Chance of Wintry Precipitation Late-Week in the East
Another cold front will dive into the northern Plains and upper Midwest midweek and through the Northeast by Friday. This cold front will also slowly push into the South late-week.
Temperatures ahead of this front will be quite mild for mid-February, ranging 10 to 30 degrees warmer than average. Highs in the 30s will reach as far north as the Canadian border of the northern Plains, with 40s in northern New England. Temperatures in the 70s are anticipated across the South.

Late Week System
Temperatures will drop below average behind this front, which translates to highs in the teens and 20s for the upper Midwest. Highs in the 40s will replace the 50s and 60s in the Ohio Valley and mid-Atlantic.
This cold front will also bring the chance for snow – or rain mixed with snow – from the northern Plains to the Great Lakes, Ohio Valley and interior Northeast Wednesday-Friday. For more details on that forecast, click the link below.
