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

...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 Plains will
be the focus for several rounds of severe thunderstorms and
drenching downpours into the weekend. Severe thunderstorms capable
of producing very large hail, damaging winds, and a few tornadoes
will be possible across a wide swath from the Plains to the
southern Mid-Atlantic. The Storm Prediction has a targeted
Enhanced Risk across Alabama and Mississippi for Saturday with
clusters of organized storms likely. A broader Slight Risk extends
around the mid-South. The severe weather threat is similar on
Sunday with a targeted Enhanced Risk (level 3/5) across the
southern Plains and a Slight Risk across the Carolinas. The Plains
will have a threat for large hail and strong winds, while the
Carolinas and southern U.S. will also see a strong wind threat and
some hail threat with storms that develop along a cold front. An
isolated tornado cannot be ruled out. 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. For tomorrow, A Slight Risk for
Excessive Rainfall is forecast for a large portion of the Middle
South with a more isolated risk across the Tennessee and Ohio
Valleys. On Sunday, the greatest threat for flash flooding will
shift westward to the southern Plains and Oklahoma as more storm
complexes likely sweep through the area once more. The Northeast
will also see some potential for isolated flash flooding on
Saturday and across the Mid-Atlantic and Appalachians on Sunday as
storms fire on a slow moving frontal boundary.

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 northern Plains  eastward to the Great Lakes.
Temperatures will be around 5-10 degrees cooler than average for
early June as highs reach the 70s and low 80s. A stronger cold
front will sweep across the northern Plains and Great Lakes on
Sunday and drop high temperatures into the 60s. Meanwhile, Texas,
the central Gulf Coast, and the West will heat up. Temperatures
out West will be as much as 15-25 degrees above normal. This will
translate to highs well into the 90s for many. Some temperatures
could reach the 100-103 degree threshold for the interior
Northwest. The Desert Southwest will have highs in the 100-110
range across the valleys. For the western and central Gulf Coast,
high temperatures will creep up into the middle to upper 90s, but
the humidity will make the Heat Risk approach the Major to Extreme
Risk likely into Monday.
