NATIONAL WEATHER SUMMARY:

Across the eastern half of the country yesterday, an Arctic intrusion has been noted as well below average temperatures were found anywhere east of the Mississippi River. The northwest flow ushering in the colder airmass has also been responsible for lake-effect snow across the lee sides of all the Great Lakes. Most downwind areas have received a trace to five inches although the northeastern shores of Ohio and western shores of upstate New York measured the snowfall on the order of feet. Some notable snow totals for yesterday include 24 inches of fresh snow in Constableville, New York, 28 inches in Ellicottville, New York, and 20 inches in South Dayton, New York. Otherwise, skies were partly to mostly cloudy across the rest of the Northeast and Mid-Atlantic while partly to mainly clear skies were noted in the Southeast.

In the western two-thirds of the United States, high pressure continued to dominate the pattern resulting in mild and dry conditions in most locations yesterday. Temperatures of 10 to 20 degrees above normal were common across California. In the Pacific Northwest, the air stagnation continued as low-level moisture trapped underneath the ridge of high pressure in place resulted in dense valley fog in western Oregon and Washington. Otherwise, skies were mainly sunny skies across the Great Basin and Four Corners in addition to most of California.
