    change this evening as southerly winds develop. A period of stronger
    downslope winds possible from late this evening through Monday
    morning possible with gusts 30-40 kts. Considerable high clouds
    through this evening. Some lower clouds will likely develop tonight
    and be capping the higher terrain to the west of the valley.
    
    For the rest of southern Nevada, northwest Arizona and southeast
    California...Mostly light diurnal winds are expected across the
    region today ahead of an approaching storm system. Strong winds will

    passage. Light rain, possibly mixing with light snow possible at
    KBIH with ceiling around 6 kft. The rain and snow shift east across
