...Synopsis...
A large-scale ridge and modest midlevel westerly flow will cross the
Rockies, while surface high pressure moves eastward from the central
Plains into the Middle MS Valley. As a result, dry/breezy southerly
return flow will beco*e established across the central and southern
High Plains -- where critically dry fuels exist.
...Central and Southern High Plains...
Southerly return flow will strengthen across the central and
southern High Plains, though boundary-layer moisture will generally
remain limited. Downslope warming/drying co*bined with diurnal
heating of a dry antecedent airmass will result in 15-20 percent
minimum RH. The warm/dry boundary-layer conditions coupled with
20-30 mph sustained southerly surface winds (gusts upwards of 40
mph) will support enhanced fire-weather conditions. The best overlap
of strong/gusty surface winds and low RH will develop from the
northern TX Panhandle northeastward into parts of western KS --
where Critical highlights remain in place. Very dry fuels (90th+
percentile ERCs) across this region will further exacerbate the
wildfire-spread threat.
Farther west, enhanced fire-weather conditions will also be possible
in the San Luis Valley, however, these conditions are too localized
for highlights.
