.PREV DISCUSSION... /ISSUED 0200 AM CDT Sun Jul 28 2024/
...Synopsis...
A midlevel shortwave trough will advance eastward across the
northern Rockies and adjacent High Plains today, while a large-scale
ridge remains centered over the southern Rockies/Southwest. Between
these two features, a belt of moderate (30-40 kt) midlevel flow will
overspread the Central Great Basin.
...Central Great Basin...
Ample diurnal heating from southern NV east-northeastward across
southern/central UT into south-central WY will yield deep
boundary-layer mixing into the moderate flow aloft. As a result,
5-10 percent minimum RH will overlap 15-20 mph sustained
southwesterly surface winds during the afternoon. Given modestly
receptive fuels through this corridor, elevated to locally critical
fire-weather conditions are expected.
...Northern Rockies and adjacent High Plains...
Large-scale ascent preceding the midlevel shortwave trough will
intercept a midlevel moisture plume, favoring isolated to widely
scattered high-based thunderstorms from the afternoon into the
evening. 0.5-0.75 inch PW and quick storm motions will contribute to
mostly dry thunderstorms, capable of lightning-induced ignitions
over dry fuels. Strong/erratic outflow winds could also acco*pany
this activity.
