.DISCUSSION...
An upper level ridge of high pressure will reside over the burn
area for the next few days. Generally, dry and warm conditions are
expected. Each day there is a 10 percent for an isolated
shower/thunderstorm. However, the probability is too low to
include in the forecast and if any precipitation falls, it should
be less than 0.05 inches in most cases. Brusda
