...NO CRITICAL AREAS...

...Central High Plains...
An Elevated risk area has been introduced for portions of southeast
WY into the NE Panhandle and far northern CO. As of 16 UTC, surface
observations are already reported 15-20% RH with winds increasing to
around 15 mph within a downslope flow regime. Winds are forecast to
increase through late afternoon in the wake of a dry frontal passage
with gusts upwards of 25-30 mph possible. Although parts of this
region have received rainfall over the past 24 hours, a 1000 acre
fire was reported yesterday (Monday) northwest of Torrington, WY,
indicating that fuels are receptive where rain did not fall.

...western Great Basin...
Shallow convective showers with occasional lightning flashes have
been noted this morning over central CA as a plume of 0.9+ inch
PWATs migrates into western NV. MRMS data show that precipitation
rates are approaching 0.1 in/hour, with an increase in rain rates
likely as convection deepens through the afternoon within the
relatively moist air mass. These trends support the previous
forecast of mostly wet thunderstorms, though a few dry lightning
strikes outside of the precipitation cores are possible. Given the
associated cloud cover, confidence in elevated fire weather
conditions across northwest NV into OR remains limited. See the
previous discussion for additional details.

.PREV DISCUSSION... /ISSUED 0131 AM CDT Tue Jun 25 2024/

...Synopsis...
An approaching mid to upper-level Pacific trough will begin to
promote breezy southwesterly surface winds across portions of far
northern CA and south-central OR later this afternoon. A small
Elevated area was considered across this region, where RH is
expected to drop into the low teens. However, given the isolated
nature of the expected elevated conditions, and overlap with less
receptive fuels, it was not included at this time.

Thunderstorms are still expected to develop this afternoon over the
Great Basin, within a mid-level plume of moisture lifting northward
out of southern CA. Initial thunderstorm development in and around
the Wassuk Range of NV, and White Mountains of NV/CA, may contain
dry lightning. A small area of Isolated Dry Thunderstorms was
considered here. However, increasing PWATS and scattered, wet
thunderstorms will soon follow. In addition, the dry lightning
strikes should remain west of the more volatile fuels found further
east/northeast of these ranges.
