.DISCUSSION...Minimal fire weather concerns Sunday through much
of next week with recent wetting rainfall, daytime humidities
above 20 to 30 percent across most of the area, and relatively
light winds. Locally lower humidities expected across Carbon
County, particularly on Tuesday when we may see near 15% daytime
minimums, but this will be brief and winds too light to warrant
near critical conditions.
