Upcoming Pattern Change Will Bring Much-Needed Rain To California And Warmer Temperatures To Central U.S. As Northeast Shivers

A pattern change is expected to take place this week that will bring long-awaited rainfall to the West, including California, and relief from the blasts of cold air in the central United States. For much of November, a southward dip in the jet stream has been in place over the central and eastern U.S. This has brought rounds of cold air, along with periods of rain and snow. In the West, the dominant pattern has been dry and mild conditions due to an upper-level ridge of high pressure near the West Coast.

High Fire Danger Continues In Southern California Through Wednesday; Pattern Change May Increase Rain Chances Thanksgiving Week

Dangerous wildfire conditions will continue in Southern California into midweek as northern parts of the state see some improvement. Thanksgiving week, a pattern change may finally occur, and that could offer some good news in the form of increased rainfall chances. Firefighting conditions will remain hostile in Southern California through at least Wednesday. Critical to extremely critical fire weather conditions are expected Tuesday, according to NOAA’s fire weather outlook. That means a combination of gusty winds and low relative humidity will lead to the potential of rapid growth for any ongoing fires and any new fires that may erupt.

States Along Colorado River Work To Finish Water Agreements As Lakes Mead And Powell Reach Critical Levels

Even as seven Western states that rely on the Colorado River for water hammer out final agreements to protect reservoirs on the river, the two lakes are less than half full. Jennifer Pitt, who works on Colorado River policy for the National Audubon Society, told the Grand Canyon News that without changes to how Lake Mead and Lake Powell are managed,levels could fall below the point where no more water can be released. “If that happened, that would be a catastrophe for this region’s economy,” Pitt said, “For all of the people who depend on the Colorado River and for all of the wildlife that depends on it as well.”

Fall, Early Winter 2018 Temperature Outlook Update: Cold In The North In October, Then Turning Milder For November And December

October is expected to be rather cold in the north-central United States before the pattern flips for November and December, yielding warmer temperatures in the northern states and colder temperatures in the southern states as winter begins. Colder-than-average temperatures are expected in October from the northern Rockies to the northern Plains and upper Midwest, with far below-average temperatures likely in the Dakotas, eastern Montana, northeastern Wyoming and western Minnesota, according to the latest outlook from The Weather Company, an IBM Business.

Fall, Early Winter 2018 Temperature Outlook: Chilly In October, Then Turning Milder In November And December

After a warm September for millions of Americans, October is expected to feel much more fall-like across the north-central and northeastern United States, but the chilly weather may be replaced by milder temperatures for the start of winter. Near- or below-average temperatures are expected in October from the northern Plains into the Midwest and Northeast, according to the latest outlook from The Weather Company, an IBM Business. The greatest chance for colder-than-average temperatures will be in the upper Midwest, western Great Lakes and parts of northern New York and northern Vermont.

July Was The Hottest Month On Record In California, Record-Wettest In Mid-Atlantic

California experienced its hottest single month in 124 years of recordkeeping, according to NOAA’s monthly summary of United States climate released Wednesday. For the contiguous U.S. as a whole, it was the 11th-hottest July on record, with almost every state coming in warmer than average. The national average of 75.5 degrees Fahrenheit was 1.9 degrees above the 20th-century norm, said NOAA. In addition, several communities in California and adjacent Nevada had their all-time hottest single month.
