FTB 06-09-2017: Very Dry Air To Overtake Colorado

Issue Date: Friday, June 9th, 2017
Issue Time: 10:05AM MDT

— Minor flooding will continue on Arkansas River near La Junta through at least Saturday
— Elevated fire danger for central and western Colorado

This morning, instead of showing water vapor imagery, shown below is the Denver atmospheric sounding from 6AM. Although the surface dew point temperature was still 51F, note the pronounced drying just above the surface. This will quickly mix down to the surface across nearly the entire state, with the exception of far eastern and southeastern areas where stubborn moisture will keep a slight chance of a weak shower/storm in the forecast.

The main headline today will be the combination of gusty winds, warm temperatures and very low relative humidity for central and western Colorado. An elevated fire danger will increase this afternoon.

Finally, minor flooding is currently occurring on the Arkansas River near La Junta. This will continue through the day, and a Low flood threat is posted here. Stay tuned to the Pueblo National Weather Service for updates.
