From NOAA:
SOUTHWEST WINDS THIS AFTERNOON WILL BLOW AT 20 TO 30 MPH WITH GUSTS TO 45 MPH. THESE GUSTY WINDS COMBINED WITH TEMPERATURES IN THE MID 70S TO LOWER 80S AND RELATIVE HUMIDITIES FROM 7 TO 15 PERCENT WILL CREATE CONDITIONS FAVORABLE FOR EXTREME FIRE BEHAVIOR THIS AFTERNOON AND INTO THE EARLY EVENING HOURS.

No wonder things feel crackly: 7-15% humidity and almost 80º in the shade. Good thing it’s going to snow tomorrow.

(make that 3º humidity…)
