As per reports, adverse weather conditions are expected in parts of the US through Tuesday (29 April).
• A low-pressure system is gradually moving away from New England into the Canadian Maritimes. Colder air associated with this system may result in rain transitioning to wet snow across higher elevations in northern New England on Sunday (27 April). Rainfall is expected to taper off by tonight.
• An upper-level low-pressure system is moving inland from California, bringing additional snowfall to the Sierra Nevada and mixed precipitation across the Great Basin today. This system will advance towards the northern Rockies by Monday (28 April), interacting with a cold front from Canada, resulting in significant snowfall across southern Montana and northern Wyoming.
• Through Tuesday (29 April), a low-pressure system will track across the northern Plains, bringing widespread rainfall and embedded thunderstorms. Severe thunderstorms, including strong tornadoes, very large hail, and damaging winds, are expected from northern Texas through the central Plains, particularly across the upper Mississippi Valley and the Mid-Missouri Valley.
• By Tuesday (29 April) morning, the low-pressure system is forecast to move into the upper Great Lakes. Rainfall could transition to wet snow, accompanied by gusty winds, as colder air surges southward from Canada.
• Very dry conditions, combined with warm temperatures and strong winds, have led to critical to extreme fire weather risks from New Mexico into western Texas. Meanwhile, a stark temperature contrast will persist: above-average temperatures will expand across the Plains, Midwest, and Southeast, while parts of California, the Great Basin, and the Southwest remain cooler than average before moderating early next week.
