Fire Weather Planning Forecast for Wrn Colorado and Ern Utah

.DISCUSSION...Rising temperatures will allow for lower
afternoon humidity, deeper mixing, and gusty afternoon
winds leading to localized critical fire weather conditions 
each day. A mid week moisture push will promote shower and
thunderstorm activity over the high terrain, especially over the
San Juans. Hot, dry, and windy conditions move back in for the
weekend raising our concern for critical fire weather conditions.
