.DISCUSSION...
Temperatures will continue to increase across the region through
midweek with an upper ridge building over Montana. The hot airmass
will also be drying out, leading to some increase in fire weather
concerns. However winds are expected to remain fairly light and
slowing the drying of fuels. A cold front passage Wednesday night
or Thursday will drop temperatures significantly for the end of
the week.
