...Monsoonal moisture likely to pose flash flooding risk to parts of the
Central Great Basin as heavy rainfall focuses along a cold front over the
Central/Southern Appalachains today...

...Severe thunderstorms possible over Midwest today, Upper Midwest on
Tuesday...

...Excessive heat persists over the Pacific Northwest today as anomalous
warmth and fire risk expand into the Northern/Central Plains...

A shortwave trough embedded within an upper-level ridge will continue to
draw monsoonal moisture up and into western/central Nevada today.
Scattered thunderstorms and isolated pockets of heavy rainfall may lead to
the possiblity of flash flooding. Therefore, a Slight Risk of Excessive
Rainfall leading to Flash Flooding is in effect for portions of
western/central Nevada as well as eastern California today.

Synoptically driven showers and thunderstorms will impact portions of the
Midwest and East today as a weak upper trough swings through the region.
Some thunderstorms may turn severe over parts of the Ohio Valley where the
Storm Predicion Center issued a Slight Risk of Severe Thunderstorms. Heavy
rainfall may focus over parts of the Central/Southern Appalachians due to
a weak upper-disturbance that that moves through the Tennessee Valley. A
Slight Risk of Excessive Rainfall leading to Flash Flooding is in effect
for parts of eastern Tennessee/Kentucky, southern West Virginia, northern
Georgia and southwestern Virginia/North Carolina today. An area of low
pressure will glide across southern Canada on Tuesday leading to the
threat of severe weather across parts of the Upper Midwest Tuesday night.

The anomalously warm airmass responsible for the ongoing excessive heat
situation in the Pacific Northwest will expand eastward into the
Northern/Central Plains today. Record temperatures are likely to be tied
or broken across the Pacific Northwest this afternoon/evening. Excessive
Heat Warnings and Heat advisories are currently in effect for interior
portions of the Pacific Northwest. Highs will soar into the upper 90s and
low 100s over the Northern/Central Plains on Tuesday which may also tie or
break temperature records. This anomalous heat paired with dry and
somewhat windy conditions may cause fires to start over the next couple of
days. The Storm Prediction Center has issued a Critical Risk of Fires for
these areas where Red Flag Warnings are also in effect.
