Good morning! Meteorologist Danielle Noyes brings your Tuesday Noyes’ Notes with classic fall weather continuing through midweek. Expect crisp air, seasonable highs in the 50s and 60s, and chilly nights ahead. Frost is likely tonight in northern New England, with more frost possible Thursday and Friday mornings. Meanwhile, Hurricane Milton is set to make landfall on Florida’s west coast by tomorrow evening, with life-threatening impacts expected. For the National & Northeast weather summary for today, read on and be sure to check back for Insights the most comprehensive update on Hurricane Milton you will find.
The nation’s attention remains focused on Hurricane Milton, which underwent rapid intensification, becoming a Cat 5 Hurricane Monday afternoon. Milton will track northeastward, with a landfall along the west coast, in and around Tampa, likely on Wednesday evening with life-threatening impacts. Significant flash flooding is likely in southern and central Florida, well ahead of the storm’s core due to tropical moisture convergence along a stalled frontal boundary. Moderate and Slight Risks of excessive rainfall are in effect for this region, particularly for urban areas in South Florida, which will continue to experience rounds of heavy rain and flash flooding.
In the Western U.S., an anomalous ridge of high pressure continues to produce a record-breaking heat wave across California and the Desert Southwest. High temperatures are expected to reach the low 100s to 110s in some areas, particularly inland, although a slight cooling trend will begin on Tuesday.
Highs across the Northeast, Midwest, and Great Lakes will range in the 60s to low 70s, a noticeable cool-down from earlier in the week. Meanwhile, the Pacific Northwest will see an increase in rain chances by today as a new weather system enters the region.
New England and Upstate New York will experience the effects of a cold front that has already moved across the region, delivering a much cooler and drier airmass behind it. This will result in partly sunny skies, cooler temperatures, and a refreshing change from the recent mild weather. Highs will range from the 50s in the north and higher elevations, to the low to mid-60s in southern New England and coastal areas.
While most of the region will remain dry, a few lingering showers may impact Downeast Maine early in the day as the frontal boundary exits to the east. Westerly winds will increase through the afternoon, gusting between 15-25 mph, adding a brisk feel, especially across coastal locations and higher terrain.
Overnight temperatures will dip into the 30s and 40s, with patchy frost likely in the sheltered valleys of Vermont, New Hampshire, and interior Maine, where lows could fall into the upper 30s. Winds will generally remain light, allowing for the potential of some frost in rural areas, which could impact sensitive vegetation. For those traveling or spending time outdoors, conditions will be cool and comfortable during the day, but outdoor activities should be planned with an eye toward the evening chill.
Marine interests should note Small Craft Advisories remain in effect for the Gulf of Maine through Tuesday afternoon, with seas ranging from 5-7 feet due to residual swells from distant Hurricane Kirk. Mariners are urged to exercise caution when venturing into offshore waters.
Looking ahead, high pressure will settle over the region by midweek, bringing dry and pleasant autumn weather for Wednesday and Thursday, although temperatures will remain on the cool side.
