from Wednesday afternoon through Thursday afternoon.
* AFFECTED AREA...Fire Weather Zone 655 Black Hills and

Slopes of the Central Cascades Generally above 1500 Feet.
* LIGHTNING...Isolated to scattered thunderstorm coverage is
possible across the southern Cascade Mountains and portions of
southwest Washington. Thunderstorms will develop late Wednesday
night and move from south to north across the area.
* OUTFLOW WINDS...Any storms that develop will be capable of gusty
and erratic outflow winds between 25 and 30 miles per hour.
Outflow winds can occur ahead of and behind storms and cause
erratic wind directions.
* IMPACTS...Scattered lightning in dry fuels can cause multiple
fire starts. Thunderstorms can also bring sudden sharp wind
shifts on existing fires, causing rapid changes in a fire's
rate of spread and direction of spread. Thunderstorm outflow
winds can be a threat for several hours following the start of
a new lightning-caused fire. If a fire were to begin, air
quality may diminish in the surrounding area.
Instruction:
A Fire Weather Watch means that there is a potential for critical
fire weather conditions to develop. Monitor the forecasts for
possible Red Flag Warnings.
