…Wet Sunday evening for much of the eastern U.S., including beneficial
rainfall for the Northeast…
…An Atmospheric River will bring heavy coastal rain and high elevation
snowfall to portions of the Northwest beginning tonight…
…Above average temperatures will continue into next week for most of the
country…
Scattered showers and thunderstorms will focus along a cold front, which
is forecast to propagate through the Midwest and East through Monday
morning. While much of the rainfall that occurs over the
Northeast/Mid-Atlantic will be mostly beneficial due to current drought
conditions, some of the rain that develops over parts of the Lower
Mississippi Valley could generate flash flooding following a rare
excessive rainfall event. Thus, Slight Risks of Excessive Rainfall are in
effect for this evening over portions of central Louisiana and western
Kentucky.
Elsewhere, a deep area of low pressure will bring periods of heavy coastal
rain and high elevation snowfall to portions of the Pacific Northwest
beginning tonight before spilling out into the Northern Rockies, Great
Basin and northern California on Monday. There will be a lull before
another, more potent, system brings excessive rainfall and heavy snowfall
potential to the region mid-week.
A predominant ridge-like pattern will promote above average temperatures
for much of the lower 48 this week. Shortwave energy will bring cooler
conditions to the West on Monday and Tuesday, while the East Coast
experiences high temperatures that are 10-15 degrees above average on
Monday. Dry and windy conditions could lead to fires over portions of
southern New England, upstate New York and northern New Jersey, where Red
Flag Warnings and an Elevated Fire Weather Outlook are in effect for today.
