A low pressure system will be over New England on Sunday, bringing rain and snow showers. The cold air on the back side of the storm will allow for some snow across much of upstate New York. Overall, any accumulation, more likely in higher elevations, will be light. This colder-than-normal air will filter into the Great Lakes, the Ohio Valley and much of the Northeast to close out the weekend.
High pressure will be centered in western Kentucky, allowing for a stretch of dry weather from the Plains to the Atlantic and the Gulf coasts. This will also allow warmth to build for much of the region.
A storm system emerging from the Rockies could cause some late-afternoon thunderstorms from the western parts of the Dakotas down into northwestern Texas and eastern New Mexico. Into the evening, these storms will spread eastward and will have the potential to bring torrential downpours that could lead to flash flooding, large hail and damaging winds.
Another storm will move into the Northwest, bringing rain showers and even some thunder from the coasts of Washington and Oregon to Montana.

A resurgence of warm, windy conditions will create a risk of fires across the Southwest through Monday. The environment will be favorable for fires to ignite and spread quickly. Wet weather set to return at midweek will lower the fire risk.
