... Fire Weather Watch in effect from Sunday afternoon through
Monday morning for abundant lightning in conjunction with dry fuels...

The National Weather Service in Pendleton has issued a Fire
Weather Watch... which is in effect from Sunday afternoon through
Monday morning.

A cold front will begin crossing the Oregon Cascades late Sunday
afternoon and continue moving northeast across the lower Columbia
Basin through the overnight hours into Monday morning. The primary
concern will be from periods of enhanced lightning activity across
the lower elevation Grasslands. Rainfall amounts are expected to
be relatively light. Additionally... winds will increase primarily
Monday afternoon behind the front with lower humidity expected due
to daytime heating. Areas north of the Horse Heaven Hills will be
the slowest to experience humidity increases.

Precautionary/preparedness actions...

are forecast to occur. Listen for later forecasts and possible
red flag warnings. For additional weather information... check out
