It will be an active week of weather across most of the U.S. as multiple systems impact the Deep South to the Northeast as well as the Pacific Northwest.
A significant snowstorm will make its presence known in the Northeast on Tuesday, as heavy snow will take place from Pennsylvania and New York through much of southern New England. Some areas could see 8 to 12 inches of snow fall! South of there, a rainy day will be on tap for the Mid-Atlantic, but a high elevation mix of rain and snow will fall along the southern and central Appalachian spine bringing up to a inch of snow at most. In the Mountain West and northern Plains, a weak disturbance will bring scattered snow and rain showers to Montana, Wyoming, North Dakota, South Dakota, and northern Minnesota.
Otherwise, the rest of the nation will be dry and quiet as high pressures loom overhead. These calm conditions will spread to more areas of the nation on Wednesday, with the exception of another Pacific storm making landfall over the northwestern quadrant of the country. In these areas, coastal rain showers will be present throughout the day while high elevation snowfall takes place.
Afternoon high temperatures on Tuesday and Wednesday will generally be in the 50s, 60s, and 70s in the central and southern Plains as well as the mid to Lower Mississippi Valley, Mid-Atlantic and Southeast. Due to the snowstorm in the Northeast, temperatures will drop to the 20s and 30s, and will be the case as well for the Mountain West in places like Montana, Idaho, and Wyoming. The rest of the West will be in the 50s, 60s, and 70s. Meanwhile, 30s and 40s can be found across the Upper Midwest and Great Lakes regions.
On Thursday, the Pacific system will continue to bring rain and snow to the Pacific Northwest from sunup to sundown. Coastal areas from San Francisco to Seattle can expect all day rain showers. The system will move eastward on Friday as there is a possibility of rain and snow to impact the central Great Plains.
On the eastern side of the U.S., potential exists for a system to impact the Great Lakes, Ohio Valley and Northeast regions on Thursday and into Friday. However, there is a lot of unknowns at this time in terms of precipitation type and where the system will set up exactly. Regardless, these areas should expect unsettled weather. Meanwhile, another system will develop in the Deep South on Friday bringing rain to Texas and the Gulf Coast.
It appears that a blast of cold air from Canada will move into the U.S., as below average temperatures will look to take place in the northern Rockies and northern Plains. As such, high temperatures on Thursday and Friday will be range from the teens to the 30s in these areas. Elsewhere, 40s, 50s, and 60s will be widespread from the central Plains through the Ohio Valley, Mid-Atlantic, and Southeast areas. Closer to the Gulf Coast, 60s, 70s, and even 80s highs will be reached. On the flip side, New England will continue to stay around or below freezing in the 20s and 30s. Along the Pacific coastline, expect 50s and 60s for highs with 70s in the Desert Southwest.
Heading into the weekend, more uncertainty lies with developing systems as cold air from the north will bring down high temperatures across most of the nation. The sogginess will continue on Saturday and Sunday for the Deep South, as multiple rounds of showers will impact the Gulf Coast states. North of there, a question of whether another snowstorm for the Mid-Atlantic and Northeast vicinities remains yet to be answered. Yet another Pacific system will make landfall impacting California, Washington, and Oregon with snow and rain all weekend.
On Monday, the story will be the same for the Western side of the U.S., as the Pacific system continues to bring low elevation rainfall and high elevation snow to California, Oregon, and Washington. Otherwise, mostly dry weather will return to Eastern Seaboard and the Central U.S.
