A low pressure system moving along the Northeast U.S. coastline will keep
much of New England in rain today. As the low pressure area begins to move
east of the region this evening, rain will begin to taper off. Farther
west, a frontal boundary extending from the central and southern plains to
the central Rockies today will result in areas of scattered to numerous
showers and thunderstorms. The system will produce accumulating snow at
the higher elevations of Wyoming today and tonight. Meanwhile, severe
thunderstorms and heavy rain are possible today across portions of the
central and southern High Plains. Please refer to products issued by the
Storm Prediction Center for further details on the severe weather threat.
On Saturday, one wave of low pressure along the front will move into the
the Ohio valley and the Mid-Atlantic, bringing scattered showers and
thunderstorms to those areas. Farther west, an upper-level disturbance
moving from the Rockies into the plains will interact with the front to
produce widespread showers and thunderstorms on Saturday from the central
and southern plains to the Mid-Mississippi valley. This second round of
storms will move into the Ohio valley and the Appalachians Saturday night
into early Sunday morning. Severe thunderstorms and heavy rain will once
again be possible Saturday and Saturday night.
High pressure will expand across the western U.S. into the weekend. This
will keep the West Coast dry, with warming temperatures expected. The
warmest conditions are expected across the interior Northwest, where
temperatures are forecast to rise into the 80s today, perhaps approaching
90 on Saturday, 10 to 20 degrees above average.
