As an upper low approached the Central Plains from the west, a dryline associated with it moved across the Southern Plains and portions of the Central Plains. The surface pressure gradient strengthened just ahead of the upper low and resulted in strong winds across the Central Plains, including north central Kansas.

The episode as NWS GID wrote it up.
As an upper low approached the Central Plains from the west, a dryline associated with it moved across the Southern Plains and portions of the Central Plains. The surface pressure gradient strengthened just ahead of the upper low and resulted in strong winds across the Central Plains, including north central Kansas. Reports of high winds began during the early afternoon of April 6th and continued across the area into the late morning hours of April 7th. The highest wind gust was 71 mph measured by a mesonet station five miles west southwest of Agra in Phillips County. There was damage reported to power poles in the Stockton area in Rooks County.

Area Forecast Discussion
National Weather Service Hastings NE
1252 PM CDT Sat Apr 6 2024
.KEY MESSAGES...
- Significant impactful weather expected today and Sunday.
- Strong non-thunderstorm wind gusts of 50-60 MPH will develop
this afternoon and continue for at least portions of the area
into Saturday night and Sunday. Blowing dust and reduced
visibilities will be possible as a result.
- A line of thunderstorms is likely (60-90 percent) to develop
along a surging dry line Saturday afternoon. There is a slight
risk (level 2 out of 5) for severe weather of any type,
although damaging wind gusts look to be the most likely
threat.
- Dangerous fire weather conditions are also expected this
weekend, even in areas where humidity values don't
necessarily fall to critical levels, due to the very strong
winds. The worst combination of wind and low humidity will be
across North Central Kansas.
- Seasonable to seasonably warm temperatures along with
predominantly dry weather is forecast for next week with good
eclipse viewing weather expected Monday.

.DISCUSSION...
Issued at 400 AM CDT Sat Apr 6 2024
Mostly clear skies and mild temperatures were observed across
the area overnight as strong southeasterly winds helped keep
temperatures in the 40s across the local area and brought
increasing moisture...with dewpoints now creeping into the mid
to upper 30s across the majority of the local area. To the west,
a vigorous upper level low can be seen churning across Idaho as
it is becoming more positively tilted and starting to shift
east. This low will help push a dry line across the area during
the afternoon hours, which should become the focus for
thunderstorm development around the 1-2 PM time frame.
Ahead of this front/dryline, winds will also intensify across
the area early this morning, increasing from the 20 to 30 MPH
pre-dawn, to gusting to near 60 MPH by late morning or early
afternoon. These strong winds will have the capability of
complicating things, picking up dust/reducing visibilities,
causing minor tree damage and increasing the fire danger across
the area. These potential threats have been covered with a High
Wind Warning and Red Flag warning, with additional details
available in the latest statements regarding these hazards and
HWO.
As the aforementioned line of storms then develops and rapidly
tracks across the area this afternoon/evening, severe weather
will also become possible, despite the somewhat limiting
instability. While not ideal for severe weather, this relative
lack of instability (with CAPE values only around 500 J/KG) will
be overcome by strong synoptic forcing and shear, which will
likely result in a line of strong storms capable of producing
wind gusts of 60 to 70 MPH winds, hail to the size of quarters
and a few isolated tornadoes from embedded low topped
supercells. While a brief period of heavy rain will also be
possible, due to the progressive nature of these storms depicted
in model data, most locations will likely only receive between
a quarter and half inch of total accumulation.
As thunderstorm coverage diminishes behind the dry line,
additional showers and possibly some isolated thunderstorms will
remain possible mainly north of I-80 through Sunday afternoon
as moisture wraps around the intensifying upper level low as it
lifts north across western Nebraska. While not all areas will
see precipitation Sunday, winds will remain strong, especially
across areas southwest of the Tri-cities, which will remain
closer to the circulation of the surface low and where a High
Wind Warning will remain in effect through 7 PM CDT Sunday
evening.
Conditions should finally improve across the area Monday as the
low continues to lift away from the region, with the subsequent
upper level low expected to pass well south of the area mid-
week. This should result in seasonably mild temperatures for
much of the upcoming work week, with predominantly dry weather.
A transitory upper level ridge late in the week could even boost
temperatures into the 70s to near 80 for Thursday and Friday
afternoons.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1241 PM CDT Sat Apr 6 2024
VFR conditions are currently in place at both terminals, along
with windy conditions. Surface winds gusting over 45kts will be
possible this afternoon as a storm system moves into the region.
Over the next several hours, there will be a chance for some
blowing dust, although confidence in visibility is low at this
time.
For later this afternoon/evening, we are anticipating a line of
strong to possibly severe thunderstorms moving through the
region. This will result in the possibility of some MVFR
conditions across the region. Winds will be shifting as the
system moves through, becoming southerly, then southwesterly.
Additionally, outflow boundaries from any storms moving through
the region will result in brief increases to winds and sudden
changes in wind direction.
Heading into tomorrow, windy conditions persist. There will be a
chance for some blowing dust in the area, although confidence in
visibility reductions remains uncertain at this time.

.FIRE WEATHER...
Issued at 400AM CDT Sat Apr 6 2024
Elevated fire weather concerns are expected this weekend as
fuels remain dry across the local area and very strong winds are
anticipated. While minimum relative humidity values are fairly
marginal (mostly above 20 percent), due to the strong winds, any
fires that do ignite will be very difficult to control, and
extreme caution is encouraged for those engaging in activities
that may result in a fire today across the entire forecast
area. Across north central Kansas, a several hour period where
critical fire weather conditions will be met is expected behind
a passing dry line - which should drop relative humidities to
between 15 and 30 percent, and a Red Flag Warning is in effect
from 3 PM to 8 PM CDT for our Kansas counties.
Continued windy conditions, with gusts of 40 to 60 MPH, are
expected again Sunday afternoon, although minimum relative
humidity values are expected to be even more marginal (mostly
above 30 percent). Evenso, for the aforementioned reasons, at
least near critical fire weather concerns can be expected, and a
Fire Weather Watch remains in effect for north central Kansas
Sunday afternoon through early evening.

Strong southeast winds are expected to intensify across the local area this morning, increasing to between 35 and 45 mph, with gusts to near 60 MPH possible by afternoon. Winds of this intensity could blow around unsecured objects, lead to tree damage, as well as result in areas of blowing dust and poor visibility across the local area. Please refer to the latest High Wind Warning message for additional details. The combination of very strong winds will also lead to dangerous fire weather conditions area wide this afternoon, with the worst conditions forecast behind a dry line over portions of north central Kansas where a Red Flag Warning remains in effect. Please refer to the latest Red Flag Warning statement for additional details. Finally, a line of thunderstorms is expected to develop southwest of the Tri Cities by early afternoon, and then race northeast through the late afternoon and evening hours. Some of these storms will likely be severe, with hail to the size of quarters, damaging winds of 60 to 70 MPH, and a few tornadoes all possible. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Strong west to southwest winds with peak gusts of 40 to 60 MPH are expected across the area on Sunday, with the highest winds forecast to be southwest of the Tri-Cities where a High Wind Warning will remain in effect through 7 PM CDT Sunday evening. Please refer to the latest High Wind Warning message for additional details. In addition, the combination of very strong winds and lower relative humidity values will lead to another round of near critical to critical fire weather conditions across North Central Kansas Sunday afternoon. Please refer to the latest Fire Weather Watch message for additional information. .SPOTTER INFORMATION STATEMENT...
