The episode as NWS GLD wrote it up.
A low pressure system swept through eastern Colorado in the early hours of the 31st. The following pressure rise behind the low pressure system resulted in strong winds. The Burlington, Colorado airport reported a 14 millibar pressure rise over 12 hours. The highest recorded gust in eastern Colorado during this event was in Yuma county with a gust of 65 mph.

Area Forecast Discussion
National Weather Service Goodland KS
455 PM MDT Fri Mar 31 2023
.SHORT TERM...(This evening through Saturday)
Issued at 138 PM MDT Fri Mar 31 2023
Latest upper air analysis shows a closed low over the Northern
Plains. As the low rotates, a cold front is sweeping southeast
across the Plains. Ahead of the cold front a dry line was moving
across the Missouri River to the east. Subsidence on the south side
of the closed low has caused the sky to be mostly clear. The
subsidence has also led to strong to high winds occurring in
Northeast CO.
For the rest of today, blowing dust could certainly occur. However,
as with yesterday the lapse rates at the mid levels are unstable
enough to allow the dust to be lofted upward instead of being
concentrated at the surface. There could be a narrow corridor of
thicker dust along Highway 36 where the lapse rates transition to
more stable. However confidence in this is low. Otherwise gusts of
60 MPH could occur over western Yuma County and northwest Kit Carson
County. At this point am thinking the gusts will be too infrequent
to warrant a warning. Dangerous critical fire weather conditions
are still expected this afternoon in the warning area.
Tonight the northwest winds will decline during the evening.
However the surface pressure gradient will remain tight over the
eastern part of the forecast area. This will allow the winds to
remain breezy there through most of the night. There will be very
weak moisture advection over the central part of the forecast area.
However soundings have a large dew point depression, so am not
expecting any fog to form. Overnight the winds will eventually
become light as the surface high moves in.
Saturday winds will turn to the southwest as another surface low
deepens over the lee of the Rockies. This will cause WAA over the
forecast area, allowing highs to be warmer than today. During the
afternoon low level winds will increase and the surface pressure
gradient will tighten over the forecast area. The strongest winds
will be over the southwest part of the forecast area. The current
forecast has the winds at the high end of the spectrum.
The latest forecast continues to meet critical fire weather
conditions. However the relative humidity is barely meeting
criteria during the afternoon. This is after the highs were lowered
slightly despite using temperature data on the warm end of the data
spectrum. In addition the HREF max wind gusts for that part of the
forecast area are less than what the current forecast is. Therefore
have decided to not upgrade the watch at this time. Confidence is
not high enough that critical fire weather conditions will be
observed long enough to meet the three hour requirement.
Saturday night the surface pressure gradient will tighten as the
surface low moves northeastward. This will cause the winds to
increase during the night. Despite the lower dew points moving in,
the breezy winds will keep lows warmer than tonight.
.LONG TERM...(Sunday through Friday)
Issued at 115 PM MDT Fri Mar 31 2023
Zonal flow on Sunday will turn southwest on Monday ahead of a
trough digging into the western CONUS. As that trough moves out, a
cut off low forecast to develop over the central Rockies on
Tuesday and move into the Nebraska panhandle by Tuesday night.
Another trough will then dig into the western CONUS Wednesday with
a return to southwesterly flow over the plains. It will shear out
and weaken through the end of the week with models showing little
eastward progression, maintaining the southwest flow aloft.
Fire weather concerns continue Sunday through Wednesday for areas
south of Interstate 70 in Kansas and Colorado. Relative humidity
will drop to less than 20 percent each afternoon. Winds appear
fairly light on Sunday favoring elevated conditions, but with more
wind on Monday and especially Tuesday critical would be favored,
then by Wednesday winds diminish somewhat but could still reach
critical criteria. Wind gusts could approach high wind criteria on
Tuesday. Rain and snow on Tuesday may mitigate blowing dust
potential.
On the precipitation side, it will be dry until the upper low
kicks out Monday night. Although initially dry slotted, wraparound
precipitation chances will begin Monday night in northeast
Colorado, then the remainder of the area on Tuesday, ending
Tuesday night. Best chances for precipitation will be north of
Interstate 70. Phase may be rain or snow, or a rain/snow mix, but
at this time little, if any, in the way of accumulation is
expected, with the main snow band staying well to the north of the
area.
Temperatures will be much above normal on Sunday, above normal on
Monday, cooling off to below normal on Tuesday with the clouds and
precipitation, remaining below normal Wednesday and Thursday.
