...Heatwave persists from the Upper Midwest to the East Coast...

...Additional heavy rain for portions of the Gulf Coast...

An early season heatwave across the northern tier of the country will
persist into the start of the week, with many locations reaching upper 80s
to upper 90s/low 100s from the High Plains to the northern parts of the
Ohio Valley. The Eastern Seaboard will also start to get toasty and humid
as the Bermuda High strengthens offshore over the next few days. The
Desert Southwest will be stifling, with daily maximums averaging 100 to
110s at the lower elevations.

Although the most of the Southern Plains and the Deep South will not be as
hot, thanks to extensive cloud cover, it will however have multiple rounds
of rain. Periods of moderate to heavy showers across the central portions
of the Gulf Coast and surrounding areas will have an increased risk for
scattered to widespread flooding through at least Wednesday morning. Some
locations may receive upwards of 3 inches in addition to what has already
fallen this weekend. Heavy rain is also expected across the ArkLaTex
region in connection with the slow moving upper low, and for the Cascades
as a couple of Pacific disturbances pass through the region. Additionally,
the Storm Prediction Center has identified most of the Dakotas and parts
of western Minnesota has having a Slight Risk of severe thunderstorms for
Monday as a defined surface low and front intercepts a warm and unstable
airmass across this region. The severe weather threat is expected to
continue of the Dakotas into Tuesday.
