A frontal boundary extending across the northern tier states is forecast to undulate as multiple low pressure waves ride along the front through the next couple days. A couple of the stronger waves are expected to trigger rounds of severe weather along with heavy rainfall from the Upper Midwest to the Great Lakes. These storms will likely become daily occurrence during the latter half of each day as they generally move from west to east across the aforementioned areas along the undulating front. The interior Northeast will also see a couple of rounds of showers and thunderstorms in the latter half of today and Wednesday.
Further south in the central/southern Plains, additional moisture returning from the Gulf will interact with a dryline to trigger additional rounds of strong to possibly severe thunderstorms with heavy downpours. These storms are expected to extend northeast across Missouri into the Midwest, again most active during the latter half of each day into the overnight hours. The strong ridge of high pressure that helps feeding the moisture into the southern Plains will also bring anomalous warmth into the eastern U.S. High temperatures well into the 80s will begin to challenge daily records this afternoon in the east-central U.S. By Wednesday afternoon, record heat with temperatures reaching into the 90s are forecast for the Mid-Atlantic region. More record heat is forecast to continue into Thursday for the Mid-Atlantic.
In the western U.S., high-elevation snow and low-elevation rain associated with an upper low will move through the Four Corners and then the central Rockies today. Meanwhile, a stronger system is approaching the Pacific Northwest. Heavy mountain snow, windy and much colder weather associated with this system will push into the Northwest on Wednesday, reaching into the northern Rockies and northern Great Basin by Thursday morning behind a strong cold front.
As the warm air expands eastward from the Plains to the eastern U.S. over the next couple of days, a cooling trend will gradually work its way across the interior western U.S. with the ongoing unsettled weather. West of the aforementioned dryline in the Plains, a combination warm temperatures, dry air and some gusty winds will promote a Critical Risk of fire weather over the central to southern High Plains and nearby southern Rockies over the next couple of days.
