.PREV DISCUSSION... /ISSUED 0321 AM CDT Sat Jul 22 2017/

...Synopsis...
Slight amplification of the upper ridge is expected across the
northern Rockies today, in the wake of an upper trough moving
east-southeastward toward the Great Lakes. At the surface, an area
of low pressure will move from the upper Midwest into the eastern
Great Lakes region, with dry northwesterly winds persisting across
the northern High Plains in the wake of a cold front.

...Eastern Montana into the Dakotas...
Elevated conditions are expected across portions of eastern MT into
the western Dakotas on Saturday, as a dry post-frontal airmass
persists over much of the northern Rockies/High Plains and modestly
enhanced west-northwesterly flow continues. Locally critical
conditions are possible. However, the strongest winds are expected
to generally be displaced to the north and east of areas with the
lowest RH, so confidence remains too low for any critical upgrade at
this time.

...Portions of Eastern Nevada...
As monsoon moisture begins to return to the Great Basin, isolated
thunderstorm development is possible this afternoon as far north as
northeast NV. Thermodynamic profiles will support mostly dry
thunderstorm activity into northern/eastern NV, though very isolated
coverage and relatively slow storm motions may tend to limit the
threat to some extent. An isolated dry-thunderstorm area has been
added to cover this threat.
