An unseasonably warm and impressively waterlogged storm system is set to bloom across the Eastern United States late this week, bringing the chance of severe weather — including a few tornadoes — and widespread heavy rains. Low pressure will form over the Texas-Oklahoma border Friday, scuttling northeast over the weekend and unleashing a slew of impactful weather.
Ahead of the storm, which will develop from a burst of energy now centered over the Gulf of Alaska, mild temperatures will feel springlike at times. Highs this weekend may approach 25 or 30 degrees above average in the East, nestled within an extended period of atypical warmth. Some temperature records may be tied or brokenBehind the storm system, colder air will make a run east, moderating temperatures into early next week. It could flip rain to snow for places like Chicago over the weekend though, possibly piling up moderate accumulations.
