Currently, a trough associated with a shortwave is pushing off east out of Ohio providing some spotty precipitation. The stalled front over the Florida peninsula is also providing some precipitation with some areas receiving locally heavy rainfall and possible storms. Out east, in the Rockies, snowfall is possible in the higher elevations associated with the low pressure that has moved through. An upper level disturbance is also providing a chance of rain in Washington.
As the low progesses eastward, the warm front will be bringing warmer temperatures along with it into the Midwest on Tuesday as temperatures will near 70F extending from Iowa into Indiana. A low pressure system will develop from Florida and travel north just off the coast, providing a chance for rain up into Virginia and along the Mid-Atlantic states before finally traveling out into the Atlantic. Again the chance for snow in the higher elevations of the Rockies exists.
Wednesday will see the cold front provide a major precipitation event along the extent of the front while high pressure builds in behind over the Rockies and along the East Coast. A new low pressure system will be moving into the Northwest providing a potential precipitation event for Washington. This cold front associated with the shortwave will usher in colder temperatures behind it as Gulf moisture will have traveled up along the high pressure system to the east bringing precipitation to much of the Plains States on Wednesday.
