.PREV DISCUSSION... /ISSUED 0158 AM CDT Sat Jun 29 2024/

...Synopsis...
An upper ridge will become established over the central CONUS as a
mid-level trough and associated upper support overspreads the
Interior West tomorrow (Sunday). Stronger flow aloft mixing down to
the surface via boundary-layer mixing by afternoon peak heating will
support dry and windy conditions that support wildfire spread. The
best chance for Critical conditions will be over southeastern Nevada
into western Utah, where 20+ mph sustained southwesterly surface
winds will coincide with 5-15 percent RH and at least modestly
receptive fuels for several hours.

Meanwhile, at least isolated thunderstorm development is expected
ahead of a surface cold front accompanying the mid-level trough over
northeast California into southwestern Idaho. Though a mix of wet
and dry storms are possible, stronger mid-level flow aloft suggests
these storms should move quickly eastward, with minimal
precipitation accumulations. Given drying fuels in this region,
lightning-induced wildfire ignitions are possible, necessitating the
introduction of isolated dry thunderstorm highlights.
