It seems like the weather patterns are quite active across various regions! Here’s a breakdown:
- Lower Mississippi Valley: Excessive rainfall and severe weather are expected to continue pushing eastward today and into Monday. While the threat of severe weather might be slightly lower than Saturday, there’s still a risk, especially in the eastern Southern Plains and Lower Mississippi Valley.
- Pacific Northwest and Northern Rockies: High-elevation snow is forecast to spread inland from the Pacific Northwest into the Northern Rockies on Monday. This is part of a larger system originating from the Pacific that will bring rain and snow to these areas.
- Midwest to Mid-Atlantic: Warmer than average temperatures are spreading from the Midwest into the Mid-Atlantic today, contrasting with below-average temperatures in the Four Corners and Rockies shifting into the Northern Plains.
- Great Lakes to New England: A low pressure system is moving away from the Great Lakes into Canada, ending scattered showers over the Upper Great Lakes but continuing them from the Lower Great Lakes into New England.
- East Coast: Strong southerly flow behind a high-pressure system will bring very warm air northward into the East Coast, with temperatures possibly reaching into the 80s to near 90 degrees for the interior Mid-Atlantic.
- Pacific Northwest again: Temperatures are expected to be cooler by Monday as a new upper-level trough from the Pacific pushes inland, bringing widespread high-elevation snow and lower elevation rain across the Pacific Northwest toward the Northern Rockies. Additionally, increasingly windy conditions are expected as a low pressure system develops over the Northern High Plains into southern Canada.
It’s a dynamic weather situation with various regions experiencing different impacts, from severe weather to snowfall and temperature fluctuations.
