Weekly Highlights November 17th to 22nd

This week, a quick-moving Clipper system will slide through the Northeast from Monday into Tuesday, bringing a light round of snow to the region. Most locations can expect anywhere from a coating to around 2–3 inches, though the fast nature of the system will keep totals modest. Another similar Clipper may follow on Saturday, potentially ending the week the same way it began, with another round of light accumulating snow. Tuesday, another area of snow will push through the Plains and into the Great Lakes. Snowfall amounts here also look light to moderate, generally ranging from a coating to 2–3 inches. South of this system, scattered showers and thunderstorms will develop, bringing a mix of wet weather to areas that remain on the warmer side.

Temperatures will trend colder through the week in the Northeast, with a deeper push of cold air arriving in the Upper Great Lakes later on. This shift will reinforce the wintry pattern developing across both regions and help maintain the chilly feel through the end of the week. Meanwhile, the Plains, Mississippi Valley, parts of the Ohio Valley, and Texas will experience multiple days of showers and thunderstorms. This unsettled stretch will extend eastward at times into the Mid-Atlantic States, keeping conditions active across a broad portion of the country. Out west, showers will persist in Southern California and parts of the Southwest. With recent wet conditions, the continued rainfall may elevate the threat of localized flooding once again this week. In the higher elevations of the Rockies, snow is expected throughout the week, with several inches likely as colder air interacts with passing disturbances.
