.KEY MESSAGES...

- Isolated thunderstorms possible through Monday morning.

- Warm and dry for the new work week.

&&

.SYNOPSIS...
Isolated thunderstorms will be possible through Monday morning
as a weak disturbance tracks through the region. Behind the
wave, a ridging pattern will lead to a return of warm, dry
conditions across the region.

&&

.DISCUSSION...
Monday: The morning will start with a weak wave moving through
the Inland Northwest form the Southwest. Ensembles have
continued to weaken the wave from previous runs. Any precip
from the is not expected to be more than a trace with the best
chance along the Eastern portion of the Basin. An isolated
lightning strike is the main concern from this wave but the
parameters are not very excited about it. By the afternoon, the
wave has exited region off the East. A ridge will begin to
build into the region from Southwest US. It will usher in a dry
warming trend that is expected to last for the rest of the week.


Tuesday through Saturday: Highs will continue to build a few
degrees warmer than the previous day. Temperatures will
gradually climb back into the 90s and low 100s by the weekend.

embedded thunderstorms are moving through the KMWH area, and are

of showers through 18Z, and a 10 percent chance of isolated
thunderstorms with these showers.

isolated thunderstorms within showers at KGEG-KSFF, so
thunderstorms not in the TAFs. Moderate confidence in light
showers through 18Z. /AS
