...Complex fire weather environment evolves this weekend... .Hot, dry and windy conditions will remain in place over most of Oregon today, and approaching monsoon moisture from the south will increase the threat of lightning across the forecast area beginning today and even more so on Sunday.

Any fires that develop will likely spread rapidly. * AFFECTED AREA...For the Red Flag Warning, critical conditions due to gusty winds and low RH are expected north of a line from Chiloquin to Paisley while lightning on dry fuels is expected south, through this evening. Tonight through Sunday, all areas are at risk for lightning on dry fuels. * WIND...Southwest 15 to 25 with gusts to 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.
