...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE CENTRAL AND
SOUTHERN PLAINS...

Expanded the Elevated area northeastward into eastern Nebraska, far
southeast South Dakota, far southwest Minnesota, and far northwest
Iowa. There will be a narrow region between the dryline and synoptic
front where warm, dry and windy conditions are expected beneath the
mid-level jet streak. The HRRR and RAP suggest these conditions may
continue even farther north, but fuels are less susceptible in this
region and the duration of these conditions should be less. Despite
the less receptive fuels, it is worth monitoring closely as
meteorological conditions may reach extremely critical for at least
an hour or two. Additionally, any fires which do develop in this
region will encounter a wind shift during the late afternoon/evening
as the front moves through.

Also expanded the Critical farther northeast across Kansas in this
same axis of strong winds and low relative humidity.

.PREV DISCUSSION... /ISSUED 0203 AM CDT Fri Apr 22 2022/

...Synopsis...
An upper-level low is forecast to develop and deepen over the
Dakotas on Saturday with enhanced mid-/low-level flow stretching
from Minnesota southwestward to West Texas.  At the surface, a
strong low pressure system will slowly drift to the north-northeast
across the Dakotas with an extensive cold front/dryline extending
southward bisecting the Plains.

...Portions of the central/southern Plains
The surface cyclone and associated dryline responsible for the
significant wildfire-spread concerns on Friday will drift eastward
on Saturday. By Saturday afternoon, the dryline is expected to mix
east to the I-35 corridor in central Kansas and Oklahoma. Widespread
20+ mph sustained winds concurrent with RH values of 15 percent are
expected to ensue in the post-dryline environment for at least a few
hours Saturday afternoon, from New Mexico into western Kansas and
Oklahoma. As a result, critical fire weather conditions are likely
across the region where dry and windy conditions will overlap dry
fuels.  Adjustments may be made in future updates if appreciable
rainfall occurs on Friday to temper fire-weather concerns for some
locations.
