As you head out for your Thanksgiving plans, two low pressure systems on both coasts will create a few travel headaches this weekend. A new weather system could also bring some minor impacts to the north-central U.S. by Sunday.
Today
A low pressure system in the Northeast will slowly drift into Nova Scotia, while the another low pressure system advances farther into the Western U.S. Minimal travel impacts are likely for the Northeast, with the main focus of travel impacts shifting to the West.
It will be another windy day across the Northeast and Northwest today. Wind gusts of 40 to 50 mph will be common in most areas, but locally higher wind gusts are possible.
Light showers are likely across the Northeast, Mid-Atlantic and Ohio Valley in the morning, with rain slowly tapering off from southwest-to-northeast in the afternoon and evening. A few wet snowflakes could mix in with the rain for the central Appalachians. For far northern portions of the Northeast, light to moderate snow will be likely throughout the day.
Northeast travel impacts include:
Frequent rain showers will occur throughout the West Coast into the lower elevations of the interior Northwest and Great Basin. Snow will also be found in the northern Rockies as well as the mountains and higher elevations in the Northwest and Great Basin for the entire day. The heaviest snow will likely fall across the Cascades and Sierra Nevada in the morning, spreading to the northern Rockies in the afternoon and evening.
Western U.S. travel Impacts include:
Sunday
The West and Northern Tier will be the places to watch for travel impacts on Sunday. The Northeast will continue to feel lingering effects from the low pressure system drifting into Nova Scotia, while a fast-moving disturbance pushes across the north-central U.S. At the same time, a large surge of Pacific moisture will move into the West thanks to the large storm system overhead.
The interior Northeast could see a few rain and snow showers on Sunday, mainly in the morning and afternoon. Besides some isolated wet spots on roads, no major travel impacts are expected here. However, some gusty winds will continue across New England, which could make it tough to drive in areas and lead to some turbulence if flying.
Mainly snow, with some freezing rain and rain in the mix is likely for parts of the High Plains during the morning and afternoon, with light to moderate snow spreading to the far Upper Mississippi Valley in the afternoon and evening. Rain is then possible over the slightly warmer Great Lakes at night.
North-central U.S. travel impacts include:
Occasional rounds of rain and mountain snow are likely throughout the West Coast into the northern and central Rockies on Sunday. The best chance of precipitation will occur along the coast from Washington into the San Francisco Bay area. Some snow could also move into the central High Plains late Sunday night.
Western U.S. travel impacts include:
Monday
The first day of Thanksgiving week sees continued disturbances across the West Coast while a classic November Great Lakes storm deepens, affecting some travelers hoping for a full week with their relatives. Weaker gusts are expected to affect Americans when compared with the weekend, but they are still worth watching out for amidst slick roadways and airports alike.
As a burgeoning low pressure system in the Central U.S. deepens in its track toward the Great Lakes, snow showers will spread and thicken across the Upper Lakes while scattered frontal showers drag eastward, mainly into the Ohio River Basin. Snow, ice, and slush from northern Minnesota through Michigan's Upper Peninsula are likely to complicate road travel, with high winds and low clouds potentially causing air traffic trouble in the western Great Lakes states. Strong thunderstorms are likely to form along the cold front in Kentucky and potentially into the Middle Mississippi Basin eastward.
Great Lakes travel impacts include:
Although most snow ceases in the eastern Rockies by the morning, those in the higher elevations should expect minor snow on roadways. The former bomb cyclone off the West Coast will remain settled, launching rain and mountain snow showers across the region, through Monday.
West Coast and Pacific Northwest travel impacts include:
Tuesday
As Thanksgiving week continues, travel conditions will remain active across the country, especially in areas already affected by unsettled weather. The West Coast, Northern Rockies, and parts of the Midwest are still the most likely to see delays, but most of the country will enjoy favorable travel weather. Let’s break it down:
Western U.S. travel impacts include:
The Pacific Northwest and northern California will see additional rounds of rain and mountain snow as a persistent storm system continues to drive Pacific moisture inland. Snow accumulations in the higher elevations of the Cascades, Sierra Nevada, and northern Rockies could make for icy, snow-packed roads.
Central U.S. travel impacts include:
Eastern U.S. travel impacts include:
Southern U.S. travel impacts include:
