United States to witness heavy rain and snow showers in December

Weather in US

Several robust storm systems are likely to approach United States during the end of November and into the second week of December.

The jet stream is expected to transform from its west-to-east through this week to a very convoluted setup next week. As soon as this happens, storms will increase in intensity after moving inland from the Pacific Ocean.

With this, areas from coastal Northwest to the northern and Central Rockies may expect rain and mountain snow of varying intensity every other day. Also, these storms could ease the threat of new wildfires igniting and help to extinguish the existing wildfires in the Southeast.

The storms will produce an inch of rain at the local level, not only in the South, but also in the Northeast. Meanwhile, one or two of the storms are likely to strengthen, thus grabbing enough moisture to produce some rainfall to parts of the central and southern Plains, easing the persisting drought conditions over the regions.

We can expect most of the storms to track from the South Central states and toward the Great Lakes and interior Northeast US over the next two to three weeks.

A storm or two can also dip far south along the Pacific coast, thus bringing rain and mountain snow to the Southwest, including Southern California. Cold air, with heavy rain or snow is also expected over parts of the northern Plains to the Upper Midwest.

If one of these storms track farther east, snow could be pulled closer to the coast in the Northeast.

The severe nature of the pattern could pump enough warm and humid air up from the south to increase the chance of thunderstorms and hence severe weather conditions.
