.DISCUSSION...

For today, afternoon humidities will fall to around 15 percent
across lower elevations of Carbon County, however winds will be
relatively light. Further east, minimum humidities will remain
above 20 percent, and southerly winds across the plains will be
breezy with gusts around 20 mph through early evening. Isolated
thunderstorms are possible this afternoon over the mountains as
well. Moisture will increase on Wednesday and will persist through
the end of the week as monsoonal flow from the southwest returns
to the district. Higher humidities and better chances of showers
and thunderstorms can be expected through this time.
