Isolated shower and severe storm chances across the Plains will defined the early week pattern. We are closely watching the chance a weak low tracks across the Midwest later this week yielding rain chances for an increasingly dry I-90/I-80 flash drought corridor. Additional showers are falling across Southern Alberta and W MT today as impressive rainfall totals pileup across acreage there. The long-range forecast favors generally warmer temperatures across the CONUS, minus TX, through early June.
