A low pressure system offshore will bring rain and a few thunderstorms to
portions of the Mid-Atlantic region today. Precipitation will taper off
tonight as the system moves out to sea. Otherwise, most of the eastern
U.S. will remain dry through Saturday.
A weakening frontal boundary will cross the northern/central plains and
Midwest today, with showers and thunderstorms accompanying the front. The
most concentrated areas of showers and thunderstorms today are forecast to
occur across portions of the Upper Midwest. The front will weaken
significantly tonight into early Saturday and precipitation will decrease
Another frontal system will cross the Intermountain West tonight, and will
reach the northern plains Sunday morning. This system will be relatively
starved for moisture as it crosses the West, with only scattered showers
and thunderstorms possible in areas where terrain will provide a focus. As
the system reaches the central U.S. on Saturday it will access better
moisture from the Gulf of Mexico, and showers and thunderstorms will once
again be possible across portions of the northern plains and Midwest.
Temperatures will be well above average through Saturday across much of
the West, northern plains, and Upper Midwest. Afternoon high temperatures
will be 10 to 20 degrees above average in these areas.
