A very busy week of weather is in store for the US as we enter the month of May. Despite the approach of summer, snow continues to be a possibility for parts of the nation. Interestingly, this comes as warmer temperatures relative to average build into most of the East Coast through late-week. Here’s your 5 Things to Watch for this week.

Unsettled Northeast:

Rounds of storm systems will move through the Northeast this week, making for very unsettled and ugly times ahead. The weather will actually stay quiet on Monday following the showers on Sunday, but that won’t stick around for much time. Clouds and showers return on Tuesday as the first disturbance passes through. We’ll then watch to the west as a more developed storm system approaches the region, bringing some rain showers to the Northeast on Wednesday. There is even the chance for light snow across parts of Upstate New York and northern New England. Scattered showers and thunderstorms will then move in on Thursday before a widespread rain impacts the region on Friday, likely making this the wettest day of the week. And yes, this unsettled weather is expected to persist into this weekend and next week.

Northern Tier Snow:

More rounds of snow is expected to impact parts of the Rocky Mountains, northern Plains, and upper Midwest this week, continuing the endless winter for some. The first storm system has already formed, and will bring snow to North Dakota, northern Minnesota, and parts of the northern Great Lakes on Monday. On the heels of that will be a more developed storm system, which will bring a more widespread and heavier snow to the central and northern Rocky Mountains Monday into Tuesday. Some of that snow may sneak into the northwestern Plains, but this will primarily be a mountain event. It’s not until Wednesday when a swath of moderate snow for yet another storm moves into the northern Plains, dumping inches of accumulation.

More Severe Weather:

Parts of the Central US can’t seem to get a break from the risk for severe weather. This actually isn’t that unusual for the region though, as this time of the year is generally when severe weather peaks. On Monday, the risk for strong storms will exist from eastern New Mexico and the Texas Panhandle through west-central Missouri. Large hail will be the main threat, but some spotty damaging winds and tornado reports will be possible. There is also an area of Ohio that will be at risk for severe storms associated with a different storm. The severe weather threat zone will expand as we get into Tuesday, with the area from the Quad Cities through northeastern Texas at risk. It’s too early to know how these storms will exactly play out, but lines of strong storms are expected. By Wednesday, we may have to watch the ArkLaTex and surrounding areas for severe storms.

Eastern US Warmth:

A building ridge over much of the East will lead to above average temperatures for many, peaking midweek. Widespread temperatures of 5-15 degree above average are expected across the Southeast and Mid-Atlantic, making for highs mainly in the 80s but there may even be some 90+ readings. Temperatures are expected to peak on Wednesday, where highs may get up to 20 degrees above average, translating to highs in the 80s as far north as the Ohio River Valley. Unfortunately, the Great Lakes and New England will not get to experience this warmth due to the active storm track.

Dry West:

While the East experiences a very wet and unsettled week, the West will be the opposite, with very dry conditions thanks to an upper-level ridge across the region. Before then, there will be some rain and snow showers across the Southwest on Monday. Even Southern California is expected to deal with this rain. By Tuesday, however, it will be dry and generally sunny with rising temperatures as the week progresses, making for a beautiful late-week.
