…NO CRITICAL AREAS…
The previous forecast (see below) remains on track. Dry conditions
will also be present across portions of the central and southern
Appalachians. Here, a severe to exceptional drought is in place,
with appreciable rainfall accumulations lacking in the past week.
The absence of a stronger sustained surface wind field will limit
robust wildfire spread (hence no highlights). However, localized
wildfire-spread concerns could materialize by afternoon peak heating
if RH can drop below 30 percent and overlap with any wind gusts.

…Synopsis…
A southern-stream midlevel trough will track eastward across the
Desert Southwest. Preceding this feature, a low-amplitude impulse
embedded in southwesterly flow aloft will cross the central Rockies,
promoting lee troughing and breezy/gusty southerly return flow over
the central High Plains. Increasing mid/high-level clouds
accompanying the impulse may stunt diurnal heating to an extent,
though modest downslope flow should offset this and yield around
15-20 percent RH. While locally elevated fire-weather conditions are
possible here, a limited overlap of the breezy winds and low RH,
combined with marginal fuels, should limit the overall fire-weather
threat.
