.DISCUSSION...
Monday marks the driest day of the upcoming week with minimum
relative humidities generally around 20-25% in valleys and 30-40%
over the high terrain. This combined with relatively light winds
means little to no threat of critical fire weather conditions.
Look for daily precipitation chances beginning Tuesday and lasting
into the weekend.
