with the exception for a slight shower/thunderstorm chance over
the Mountains on Monday. Expect gusty northwest winds this
afternoon mainly for areas east of Billings. High temperatures
today and Monday will be slightly above normal in the lower 70s.
Afternoon humidities will be 25 to 35 percent both days. However,
some lower 20s will be likely this afternoon for the northern
