Wet in the East, Wet/White in the West, Active Pattern For The United States East and West Coasts (credit: NOAA,WPC)
An active pattern is on the way for much of the eastern U.S. over the next 7 days. As depicted in the figure from the Weather Prediction Center, a widespread area of 1-3 inches of precipitation (with higher amounts possible) will impact regions up and down the eastern seaboard including the southern and eastern Great Lakes and into southeast Canada. This heavy precipitation will be associated with two low pressure systems that will track into the eastern U.S. The first of the two storm systems produced severe weather including dangerous tornadoes on April 2nd and continued to produce severe weather and heavy rain in the southeast on April 3rd. The first storm system will continue to track northeast into the Midwest and Great Lakes spreading healthy precipitation amounts throughout the Midwest and Northeast. Some of this precipitation will fall as snow in interior New England. The second low pressure system will move into the southern U.S., with another threat for localized severe weather. This system looks to follow a similar track as the first system with heavy precipitation in comparable areas. Enough sufficiently-cold air is currently forecast such that snowfall is anticipated in and around the Great Lakes. These two systems will produce the precipitation totals in inches (as reflected in the Weather Prediction Center’s 7-day outlook attached above).
As the second system continues to lift away from the Northeast, a potent low pressure system is forecast to slam the Northwest U.S. coast with heavy rain and several feet of mountain snow possible. An incredible wet season for the West Coast that has wiped out most drought conditions looks to continue for at least the next seven days. One must ponder, how long will this type of pattern continue for?
