Matt Noyes preps us for the return of snow, mix and rain to New England later today, but also explains how each storm – today’s and another Tuesday Night/Wednesday – will see warm air gaining more ground in New England. In fact, Matt says the midweek storm may bring one to two inches of rain with a warm wind. Full details in today’s video.
National Meteorological Summary:
The start of the workweek will feature a variety of weather hazards across the United States as systems bring winter weather, heavy rainfall, and strong winds to different regions.
- Eastern U.S.: A wave of low pressure lifting through the Northeast brings a wintry mix of snow, sleet, and freezing rain to interior New England late Monday into Tuesday morning. The potential for light ice accumulations exists, particularly in northern Vermont, New Hampshire, and western Maine. By midweek, a rapidly intensifying storm will bring heavy rain and gusty winds to the Mid-Atlantic and Northeast. Rainfall amounts of 2-3 inches are expected in the I-95 corridor, with urban and poor drainage flooding possible. Cold air sweeping in behind the system Wednesday night into Thursday will lead to lake-effect snow downwind of the Great Lakes.
- Southern U.S.: A robust cold front will develop showers and thunderstorms across the Gulf Coast on Monday and Tuesday. The heaviest rain will focus over southern Louisiana and coastal Mississippi, where a Slight Risk of excessive rainfall highlights localized flash flooding concerns. Temperatures remain mild ahead of the front, with highs in the 60s and 70s.
- Western and Central U.S.: A deep upper-level trough digs into the Intermountain West and Rockies, resulting in colder-than-average conditions. Snow is likely for the Colorado Rockies and northern New Mexico by late Monday, with up to 8 inches of snow over higher elevations. Farther east, the Plains will experience a significant cooldown as Arctic air surges southward behind a sharp cold front.
- Pacific Northwest: A new storm system brings rain and high-elevation snow to western Washington and Oregon by late Monday into Tuesday. Heavy snow is expected in the Cascades, with totals exceeding 10 inches at the higher passes. Coastal areas will see windy conditions, with gusts topping 40 mph.
Northeast Weather Story:
The Northeast will contend with a mix of wintry and rainy weather over the next few days as multiple systems sweep through the region.
- Monday: A warm front pushes into the region during the afternoon, spreading snow and mixed precipitation across upstate New York and northern New England. Snow accumulations of 3-6″+ are expected in higher elevations like the Green and White Mountains, with minor sleet and freezing rain possible in the sheltered valleys of Vermont and New Hampshire. The Hudson Valley and southern New England will see mainly rain. Highs range from the upper 20s in the mountains to mid-40s near the coast.
- Monday Night into Tuesday: Precipitation tapers to drizzle or freezing drizzle after midnight, especially in the interior. Tuesday starts with low clouds and areas of fog, with scattered light rain or drizzle continuing through the day. Temperatures rise into the mid-40s to lower 50s in the valleys but remain near freezing in parts of northern Vermont and New Hampshire, maintaining a risk for patchy freezing rain.
- Midweek Storm (Tuesday Night-Wednesday): A potent low-pressure system intensifies as it tracks near the East Coast, bringing widespread rain and strong winds on Wednesday. Rainfall totals of 1-3 inches are forecast, with locally higher amounts in southern New England. Urban flooding and stream rises are likely, especially in areas where the ground remains frozen. Gusty southerly winds of 40-50 mph will affect coastal areas. As colder air sweeps in Wednesday night, rain may briefly change to snow in interior New York and northern New England before ending.
- Thursday and Beyond: Behind the storm, lake-effect snow develops in western and northern New York, with several inches possible in favored areas. Highs will drop into the 20s and 30s across the interior, with brisk northwest winds keeping wind chills in the teens. Dry but cold conditions dominate heading into the weekend, with the next chance for precipitation arriving early next week.
