.DISCUSSION...
While much of the area has received wetting rainfall over the
last 24 hours, a warming and drying trend will begin tomorrow
after this storm system departs. Winds will be fairly light on
Wednesday keeping fire weather concerns to a minimum. However,
increasing winds west of the Laramie range on Thursday will lead
to elevated fire weather conditions. Widespread elevated
fire weather conditions are expected Friday and Saturday with
gusty southwest winds and near record high temperatures pushing
RH to between 7 and 14 percent. Cooler and possibly wetter
weather will return Sunday into Monday.
