URGENT - FIRE WEATHER MESSAGE
National Weather Service Denver/Boulder CO
343 AM MDT Thu Aug 20 2020
.Lightning and new fire starts, along with gusty outflow winds,
will be the main concerns today. An increase in mid level moisture
today will lead to an increase in shower and thunderstorm
activity, only a few of which will produce wetting rains of one
tenth to one quarter inch. Most areas will only see light if any
rainfall. Given how dry the fuels are and receptive to burning,
lightning may easily start new fires.
There will also be gusty outflow winds from the passing showers
and storms. Most of these will be moving in from the west and
northwest, so weather spotters will be essential today in giving a
heads up to field crews. Peak gusts to 30 to 45 mph can be
expected ahead of, and during any of the showers and storms
today.
Moderate to good humidity recovery will finally occur tonight
thanks to today's increase in moisture and clearing skies/light
winds tonight.

50 mph possible.
