.DISCUSSION...

Isolated showers and thunderstorms are possible (~25% chance) now
through 2100 MDT. Lightning and outflow winds of 30-35 mph will be
the main concerns. Current radar imagery shows a storm north of
the SAR, however it is not expected to impact the area. Winds are
generally from the east/southeast, with gusts up to 20-25 mph at
the peaks. Expect this to continue for the next couple of hours
before weakening to under 15 mph throughout the night.
Temperatures are in the upper 50s and should get down to the
upper 30s overnight.

For tomorrow, expect light winds (10-15 mph) generally from the
east throughout the morning and afternoon. Scattered showers and
thunderstorms are possible (30-40% chance) in the afternoon,
particularly 1400-1800 MDT. Lightning and outflow winds of 30-35
mph will be the main concerns.
