URGENT - FIRE WEATHER MESSAGE
National Weather Service Pendleton OR
154 PM PDT Tue Jul 6 2021

...LIGHTNING THREAT LATE TODAY AND OVERNIGHT FOLLOWED BY DRY AND 
WINDY CONDITIONS TOMORROW AFTERNOON...

.Increased storm chances late today through early morning 
tomorrow followed by dry and windy conditions tomorrow afternoon. 
This is attributable to an upper low lifting north and east the 
next 24 hours that will break down a ridge that is currently 
overhead. 

Isolated to widely scattered thunderstorms are expected initially
over the eastern mountains late today and this evening followed 
by storm chances shifting more to south central WA and the 
northeast mountains, mainly after midnight. This will be followed
by moderate winds and critical RH from the east slopes and 
eastern Gorge across the Basin.

...FIRE WEATHER WATCH IS CANCELLED FOR ABUNDANT LIGHTNING FOR

The National Weather Service in Pendleton has cancelled the Fire
Weather Watch.

The threat for abundant lightning has lowered along with storm
chances this afternoon and evening. However, a brief widely 
isolated storm cannot be ruled out towards the east slopes of 
central Oregon late today and this evening. Elevated fire weather
conditions are expected tomorrow as low RH will combine with 
light westerly breezes for a few hours.
