FTB 09-06-2017: Light Showers over the Southern High Country and a Rebound of High Temperatures

Issue Date: Wednesday, September 6, 2017
Issue Time: 09:50AM MDT

Flooding is NOT expected today

Mostly clear skies with the exception of a few high clouds over the state. Some haze is still being reported over the northwest corner of the state and high country from the wildfires up north. Low temperatures overnight should start to recover quickly this morning with the sunrise. High temperatures will also be on the uptick today after a nice break from the heat yesterday. 700mb temperatures are about 6C degrees warmer than yesterday putting the eastern portion of the state much closer to climatology. Northwest flow at the upper-levels will occur again today with the strong 500mb ridge that extends from the Pacific Northwest to the Desert Southwest. This ridging pattern will produce another day with hazy conditions statewide, except over the Northeast Plains, which should experience some relief from the smoke. The smoke will again be confined to the upper-levels with the exception of the northwest corner of the state. Visibility this afternoon is forecasted to be in the 6-7 mile range, which is similar to yesterday.

Precipitable Water values near climatology are expected (0.6 inches) over the southern portion of the state. With some instability building over the southern mountains, a few showers are likely to form again this afternoon with upslope flow. Rainfall totals will be limited, but stronger showers could produce up to 0.6 inches. Showers should quickly end after sundown.
