November Outlook: Mild Temperatures Expected For Much of U.S.

November weather conditions in the U.S. will likely be similar to what we have experienced in October, but that may change later in the month, according to the latest November outlook issued by The Weather Company, an IBM business.
Much of the central and eastern U.S. will continue to find above-average temperatures due to a dominant upper-level ridge of high pressure.
The areas which are expected to see temperatures the highest above average include the northern Plains, the Midwest and the northern Rockies. Parts of the South, East and along the West coast, however, are forecast to see temperatures close to average for this time of year.

"The unusually strong Pacific jet will likely persist during at least the first half of November, resulting in a flood of very mild air across much of the U.S.," according to Dr. Todd Crawford, chief meteorologist with The Weather Company.
However, a pattern change may set in later in the month.
An upper-level ridge of high pressure is expected to develop over the West in mid-November. As the upper-level ridge builds, a southward dip in the jet stream, or upper-level trough, will develop over the East.
Therefore, blasts of colder temperatures in the East will be more likely later in the month. This will also allow the warmer-than-average temperatures to slide westward.

November Precipitation Outlook

This pattern is also expected to keep a swath of the West Coast, from Washington and Oregon to northern California, wetter than average in November. This is good news for the multi-year Western drought.

Otherwise, the jet stream is expected to keep the storm track closer to the Canadian border in the rest of the country, which will make for drier-than-average conditions in the southern tier of the U.S.
This is not good news for the increasingly dire drought in the Deep South, Tennessee Valley and southern Appalachians.
