.DISCUSSION...Isolated showers are pushing through the fire area
right now (1325), with brief light to moderate rain possible. Gusty
and erratic winds are likely as showers move south of the fire. While
lightning threat is low (best chance east of fire), a lightning strike
is possible with any stronger shower this afternoon; although biggest
threat is gusty winds.
Outside of showers, winds will remain out of the north-northeast
this afternoon and evening. Some sheltering of winds is possible in
heavier timber and west facing slopes tonight with strongest winds
expected on exposed ridges, higher slopes, and east facing slopes.
Expect very good RH recovery tonight (~85%) with rain chances
diminishing after 2100-2200.
Northeasterly winds will persist tomorrow with strongest winds again
on east facing slopes and exposed higher slopes. Chances of rain increase
after 1200-1400, although rain will be spotty and light (chance of wetting
rain ~20%). Thunder/lightning threat is very low tomorrow and daytime
minimum RH will fall to around 45-50%.
