...FIRE WEATHER WATCH NOW IN EFFECT FROM SUNDAY MORNING THROUGH
SUNDAY EVENING FOR ABUNDANT LIGHTNING ON DRY FUELS FOR FIRE
WEATHER ZONES 624 AND 625...
* IMPACTS...Given the recent prolonged stretch of very hot and
very dry conditions, lightning efficiency will be high to very
high for fire starts. Any fires that develop will likely
spread rapidly.

conditions due to gusty winds and low RH are expected north of
a line from Chiloquin to Paisley while abundant lightning on dry
fuels is expected south.
* WIND...Southwest 15 to 25 with gusting 25 and 35 mph.
* HUMIDITY...7 to 12 percent.
* THUNDERSTORMS...Isolated to scattered high based storms that
are likely to have very little to no precipitation,
especially outside of storm cores. Lightning strikes outside
of precipitation cores are possible and cause for concern.
* OUTFLOW WINDS...Gusts up to 35 mph. These outflow winds can
travel up to 50 miles away from the thunderstorm that caused
it.
* ADDITIONAL INFORMATION...The best chance for storms will be
Saturday afternoon into Saturday evening, then again Sunday
