Vertical Cross-Section along the Path of Totality:

A look at RH & clouds above the terrain across the USA,
from the coast of Oregon to the coast of South Carolina.
Only includes clouds below @ 14,000-ft. elevation.
Valid at Noon MDT (1100 PDT, 1200 MDT, 1300 CDT, 1400 EDT)

This is an experimental product that NOAA is currently working on.

NEMS Model:

NOAA Environmental Modeling System

Scale is from white or light gray representing 10 to 25% sky cover. Up to very dark gray representing near 100% cloud cover.

ECMWF Model:

European Center for Medium-range Weather Forecasts

a.ka. The “Euro” Model

Scale is from a dim but darker gray, representing 10 to 30% cloud cover. To a dim but whiter shade, representing something more than 50% cloud cover. To areas where cloud cover is hatched and colorized,  representing 80 to 100%, and precipitation is also likely.

GFS Model:

Global Forecast System

Scale of cloud cover:
CLR = Clear skies
FEW = 10 to 20%
SCT = 30 to 50%
BKN = 60 to 70%
OVC= Overcast or 100%

Cross sections generated from the NEMS Model:

Extends vertically to an elevation of @ 35, 000 to 40, 000 ft.

Large Active Fires Map:

Biggest fires are red & blue dots, seen over Western Oregon near Crater Lake and also up in the mountains of far western Montana.

Hi-Res Satellite of Oregon:

Smoke plumes can be seen coming off of the largest fire just west of Crater Lake and that smoke thins out as it spreads across the southern half of Oregon in the upper levels of the atmosphere.

Hi-Res Satellite ID-MT:

Smaller fires burning in north-central Idaho and in western Montana mountains. Smoke is trailing off almost to the due East in a moderately strong Westerly flow aloft.
