...CRITICAL FIRE WEATHER AREA FOR THE NORTHERN TEXAS PANHANDLE INTO
WESTERN KANSAS...
Added a Critical delineation for portions of the northern Texas
Panhandle into western Kansas. Winds are expected to be 20 to 25 mph
across this region with relative humidity in the upper teens. Some
guidance suggests relative humidity below 15 percent during the late
afternoon. However, even if relative humidity stays in the upper
teens, extremely dry fuels are still present across the area and
thus, the Critical area seems justified.

.PREV DISCUSSION... /ISSUED 0122 AM CDT Mon Apr 25 2022/
...Synopsis...
Fire weather concerns will increase on Tuesday for portions of the
southern to central High Plains as a dry return flow regime beco*es
established. Zonal flow is expected to increase over the central
Rockies through the day Tuesday, resulting in a deepening lee trough
across the central High Plains. Despite strengthening southerly
flow, moisture return is expected to be minimal after Monday's
frontal intrusion to the northwestern Gulf Coast. Consequently,
dry/windy conditions are expected that will support increasing fire
weather concerns across the Plains.
...Southern to Central High Plains...
Upper-level ridging will likely yield mostly clear skies across the
Plains on Tuesday. The diurnal warming of an antecedent dry air mass
will support deep boundary-layer mixing and widespread RH reductions
to 20-25% by mid to late afternoon. Sustained pressure-gradient
winds near 20 mph will likely see frequent gusts to 25-35 mph from
west TX into southern NE. Ensemble consensus suggests that a broad
swath of elevated conditions is likely, but drier members hint that
critical conditions are possible across northeast NM and the OK/TX
Panhandles into western KS where RH may fall below 15%. Regardless,
fire weather concerns are expected given receptive fuels (ERC values
above the 90th percentile) across most of the region. A Critical
risk area and an expansion of the Elevated risk may be warranted if
guidance continues to trend towards the drier solutions.
