Tuesday\u2019s High Temperatures + Anomaly and Significant Weather

A weak storm system will provide some wet weather from Monterey Bay northward into NorCal. The main story will be continued Lake Effect snowfall in the lee of the still quite warm Great Lakes.

\"\"

The big winners will be downwind of Erie and Ontario as the westerly winds have the longest zonal fetch over the lakes. 30-inches or more on the Tug Hill Plateau.

Chilly weather continues across the eastern U.S. with temperatures below freezing in the Great Lakes for daytime high temperatures. We\u2019ll be lucky to see 50\u00b0F here in Atlanta after a freeze. Only 20s in Milwaukee, Chicago, and around 30\u00b0F in Minneapolis, Detroit, and Cleveland.

64 million Americans will be stuck at/below freezing on Tuesday.

No 80\u00b0F high temperatures on Tuesday, November 28 is rather rare as well.

7-Day Precipitation Outlook

\"\"

Another major rainfall event takes shape across the Gulf Coast and Southeast into the weekend. Totals of 2-4\u201d of rainfall look likely from this very moist pattern off the Gulf of Mexico.

A decent atmospheric river event pounds the Pacific Northwest later on Friday into the weekend.

2023 Atlantic Hurricane Season

Quiet. Nothing expected as a relatively quiet 2023 hurricane season ends this weekend.

2023 Eastern & Western Pacific and Northern Indian Ocean

An area of low pressure could develop into a powerful Tropical Cyclone by this weekend, and affect the Indian coast next week. Still too soon to pinpoint impacts on land or maximum intensity. Early December is not unusual for tropical cyclone development in the Bay of Bengal.
