Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1128 AM CDT Mon Jun 27 2022

Valid 271700Z - 281200Z

...Dry Thunderstorms...
With another day of scattered thunderstorms expected across the
Great Basin and Western Slope, lightning will remain possible over
patchy receptive fuels intermixed with much wetter areas. Area
gauges have shown steady accumulation over the last several days,
with a significant gradient in precipitation within the higher
terrain. Model soundings continue to show profiles marginally
supportive of isolated dry strikes with PWATs ranging from 0.5 to
0.9 inches, and mixed-layer LCLs of 6-9k feet AGL. Given scattered
storm coverage across much of AZ and CO, confidence on the coverage
of drier storms (especially south and east) is low. However, the
coverage of lightning is likely sufficient to support a risk for
wet/dry flashes within patchy receptive fuels. Areas of AZ and CO
were removed from the IsoDryT area to better capture the greatest
risk for more Isolated dry lightning. Otherwise, the previous
forecast remains valid, see below for additional information.

.PREV DISCUSSION... /ISSUED 0208 AM CDT Mon Jun 27 2022/

...Synopsis...
Upper ridging will dominate the interior West as a mid-level trough
impinges on the West Coast today. Upper forcing associated with the
approaching trough will encourage dry and windy conditions over and
to the lee of the southern Cascades/northern Sierra, with Elevated
highlights introduced given the presence of modestly dry fuels.
Mid-level moisture will meander over the eastern Great Basin into
the Four Corners, with isolated to scattered high-based thunderstorm
development expected with the onset of diurnal heating. Isolated dry
thunderstorm highlights have been issued since thunderstorms (albeit
slow moving and occasionally wet) should traverse fuel beds that are
critically dry on a spotty basis.
