WEATHER SYNOPSIS
http://www.nwccweb.us/predict/forecast.asp
Warm, dry weather will prevail across the Pacific Northwest today and Thursday as an upper level ridge strengthens over the area. A cut off upper level low containing tropical moisture will swing inland into Western Washington Friday afternoon then continue slowly to the ESE through the weekend. The upper low will exit NE Oregon and track into Idaho Sunday night. Due to the moisture and instability contained in this system, lightning will be abundant but so will rainfall.
LARGE FIRE POTENTIAL

The combination of dry fuels and increasing instability will elevate the burn environment in C1 into the high risk category for Thursday. As the upper low moves inland Friday and crosses the weekend it will bring showers and thunderstorms with it. While this will increase initial attack activity…rainfall accompanying the storms will keep the threat of new large fires below the high risk category. For Friday in C1, E1 and C2 the probability of getting a new large fires is roughly 15% and around 10% for E2, but falls rapidly as the weekend progresses.
