Yikes! Widespread temps in the 30s with some 20s and even a couple of teens this morning will lead to exactly what you’d expect – a brisk fall day! Matt Noyes says we can expect a widespread frost and freeze again overnight tonight before a huge turnaround in temperatures later this week.

National Weather Summary for Monday, October 28, 2024:
A pronounced split in the country’s weather pattern sets up as a strong upper-level ridge dominates the Plains and Midwest, promoting well-above-average, record-challenging temperatures, while a deepening trough impacts the western U.S., bringing widespread precipitation, mountain snow, and gusty winds.
The West will experience another round of valley rain and heavy mountain snow across the Cascades, northern Rockies, and the Great Basin as a robust cold front pushes southeast, followed by much cooler temperatures and gusty winds through midweek. Snowfall of 6-12 inches is expected for higher elevations from the eastern Great Basin into the central Rockies by Tuesday, and localized snowfall totals of 4-8 inches may develop across the Black Hills by midweek. Temperatures behind this front will continue to fall, bringing high temperatures down to the 40s and 50s across much of the West by Tuesday.
Meanwhile, a strong ridge building across the Plains will drive unseasonably warm air into the central and northern U.S., with high temperatures from the 70s to lower 90s expected across the Plains and Midwest. This warmth will expand eastward over the next few days as the cold front moves slowly across the Plains, with scattered thunderstorms expected to develop by Tuesday into Wednesday, primarily across the Great Lakes and northern Plains, where low-end severe potential exists. Conditions will remain mostly dry across the eastern U.S. through Tuesday, with seasonable temperatures and some patchy frost possible even in the Mid-Atlantic overnight before warmer air arrives midweek.
Northeast Weather Story for Monday, October 28, 2024:
The Northeast begins the week with high pressure, bringing mostly clear skies and dry conditions, but chilly temperatures will linger as a reinforcing shot of cool air has settled in behind a cold front overnight Sunday Night. Highs Monday will be cooler than usual, staying between the 40s and 50s across most of the region, with mid-30s to low 40s at higher elevations in New York, Vermont, New Hampshire, and western Maine. Light southeast to onshore winds will develop by late Monday, bringing in moisture through the low levels. This marine flow could lead to spotty drizzle late Monday night, primarily along the coast and east of the I-95 corridor, but precipitation will be limited due to a lack of stronger lift.
By Tuesday, a warm front will approach, bringing increasing clouds by afternoon and scattered showers Tuesday night, especially from New York into northern New England. Rainfall will be light but could briefly lower visibility, especially in the valleys of northern New York and Vermont. Temperatures begin to moderate through Tuesday, reaching highs in the upper 40s to low 50s for northern New England and low to mid-60s southward into Massachusetts and Rhode Island.
Looking ahead, a significant warm-up is expected midweek as strong southerly flow builds, with daily highs potentially reaching record levels on Wednesday and Thursday. Temperatures could soar into the upper 60s to mid-70s across the interior Northeast on Wednesday and approach or even exceed 80 degrees on Thursday in southern New England, setting up for an exceptionally warm Halloween.
