.DISCUSSION...Due to lighter winds critical fire weather 
conditions remain localized today, although widespread single 
digit relative humidity values are being observed across the 
region this afternoon. A weak push of moisture will raise relative
humidities beginning tomorrow, but this moisture also brings low 
chances for dry thunderstorms, lightning, and gusty outflow winds 
tomorrow and Tuesday. Over the San Juan Mountains there is a very 
low chance of wetting rains tomorrow afternoon, and increased 
chances Tuesday afternoon. Drier air returns on Wednesday, but 
marginal wind gusts keep critical fire weather conditions mostly 
localized. 

...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS
