More Snow and Severe Weather Possible This Week in Parts of Western, Central U.S.
Published: April 16, 2018
Although it is mid-April, more snow is possible from two separate systems in the week ahead, and there is also the chance for another round of severe weather.
Below, we take a closer look at both potential systems.
The next system to watch will first bring rain and mountain snow to the northern Rockies and Sierra Nevada Monday.
This area of low pressure will press into the Plains Tuesday night and will track into the upper Midwest Wednesday. By Thursday into Friday, this system will pivot through the Great Lakes and parts of the Northeast.
With below-average temperatures in place, snow or a mix of rain and snow will spread from the northern Plains into the upper Mississippi Valley and much of the Great Lakes Tuesday night through Wednesday.
Light snow and rain may linger in upstate New York and northern New England into Thursday or Friday.
Precipitation amounts are currently expected to be light in most areas east of the Rockies. However, an area of moderate, even heavy, snowfall cannot be ruled out from parts of eastern South Dakota into southern Minnesota, northern Iowa and central Wisconsin.
The National Weather Service has posted winter storm watches for parts of southern Minnesota and northern Iowa due to the higher potential of significant accumulating snow in a narrow corridor across this region. This includes Sioux City, Iowa, and Rochester, Minnesota.
The next system is expected to be stronger than the midweek disturbance.
An area of low pressure with a deep upper-level trough, or southward dip in the jet stream, will move across the West late-week.
This low-pressure system is also anticipated to take a more southerly path into the Southwest.

When this system emerges in the southern Plains, it will likely strengthen.
After blanketing the central Rockies with snow, there is the potential for snow or a rain and snow mix in the central High Plains and Front Range of the Rockies by Friday or Saturday. The ultimate track of the low and temperatures will determine whether this snow threat will target the Colorado Front Range, including Denver.
On the warm side of this system, severe thunderstorms are a concern in portions of the southern Plains Friday into the weekend.
Another factor to consider from this system is the potential for some desperately-needed rain, possibly a soaker in spots, over the worsening drought in the southern High Plains.
