...Episodes of severe thunderstorms on tap for portions of the central and
southern High Plains, the Tennessee and Ohio Valleys, southern New
England, and into the Southeast Friday and Saturday...

...Heavy showers capable of producing instances of flash flooding expected
across portions of the central/southern High Plains eastward into parts of
the Tennessee Valley, Mid-South, and southern New England into the
weekend...

...Below normal temperatures in store from the Rockies into the Great
Lakes while heat builds across the Southern U.S. and the Pacific Northwest
through Saturday...

A slow-moving, wavy frontal system stretching from the Northeast to the
Ohio/Tennessee Valleys to the central/southern High Plains will be the
focus for several rounds of severe thunderstorms and drenching downpours
Friday into the first half of the weekend. Warm and moist air south of the
wavy front will clash with cooler and drier air to the north of it,
setting the stage for an active stretch of weather for a large portion of
the country. Severe thunderstorms capable of producing very large hail,
damaging winds, and a few tornadoes will be particularly concerning across
parts of the central and southern High Plains today, with the Storm
Prediction Center highlighting the threat with an Enhanced Risk (level
3/5) of severe weather. Strong to severe thunderstorms will also be
possible farther east across parts of the Tennessee/Ohio Valleys and
southern New England, with a Slight Risk (level 2/5) outlining the
potential for strong winds, hail, and even an isolated tornado or two. In
addition to the severe weather threat, these same regions will also have
to contend with bouts of heavy rainfall, some of which could lead to
scattered instances of flash flooding. On Saturday, the risk for severe
weather and excessive rainfall will shift south and east a bit, targeting
more of the Mid-South, Tennessee Valley, and the Southeast as additional
waves of low pressure develop along the slow-moving front. Similar to
today, heavy showers and strong to severe thunderstorms will threaten to
produce damaging winds, large hail, a couple tornadoes, and flash
flooding.

In the wake of the front, high pressure building in from the northwest
will lead to a period of cooler than normal temperatures from parts of the
Rockies and the Intermountain West eastward to the Great Lakes through
Saturday. The coolest temperature anomalies will be found from southeast
Wyoming and western Nebraska to eastern Colorado and western Kansas today
with high temperatures 10 to 15 degrees below normal. On the other side of
the coin, summer-like heat will build across the southern tier of the U.S.
and much of the Pacific Northwest through the weekend. Temperatures of 10
to as much as 25 degrees above normal will translate to highs well into
the 90s and 100s. In fact, by Sunday, high temperatures could threaten
records for parts of the Pacific Northwest, with even more records
possible on Monday.
