.SHORT TERM /THROUGH SUNDAY/...
Issued at 208 PM CDT Sat Mar 23 2024

Synoptic overview and current conditions: Water vapor and upper
analysis show a departing low pressure system over the southeast
U.S. and the next upper low off the Oregon coast. Pacific
moisture was streaming eastward into the southern plains south
of the low with a strong upper levle jet streak. Surface low
pressure was developing in the high plains into the Rockies in
advance of the next system. Large stratus deck which was over
the entire CWA earlier today has quickly eroded this afternoon
with plenty of sunshine for the afternoon. Temperatures were
chilly in the 40s across the area, but with sunshine during the
afternoon should climb back into the 50s.

Tonight: A good area of upper divergence will spread into the
plains ahead of the next upper storm system. Southerly winds
will significantly increase in the plains as the pressure
gradient increases ahead of the developing surface low and
departing high pressure system. Our CWA will be on the edge of
the stronger winds tonight, but may see some gusty winds develop
at SGF with a favored funneling wind direction. Lows tonight
will be warmest out west in the mid 40s to the mid 30s in the
east.

Sunday: The pressure gradient will increase over the CWA on
Sunday and will see some gusty winds across the area, with some
gusts of 30 to 35 mph possible during the day. Upper level
divergence will increase over the western CWA late in the day
with shortwave energy spreading into the area. Surface low will
move into western Kansas. May see some showers develop late in
the day, but will need to overcome some very dry low levels for
anything to reach the ground. Widespread elevated fire weather
conditions are expected with some spotty localized significant
fire weather east of Springfield. Afternoon humidity levels are
expected to dip into the 20 to 30 percent range in the eastern
CWA with 30 to 40 percent humidity levels over the remainder of
the CWA. Afternoon high temperatures should reach the upper 50s
to low 60s.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Issued at 208 PM CDT Sat Mar 23 2024

Sunday night into Monday night: Very windy conditions will then
develop Sunday night into Monday across the area as the low
pressure system approaches from the west. May eventually need a
wind advisory for the northwest half of the CWA during this time
frame with wind gusts of 40 to 45 mph possible. Rain chances
will increase on Sunday night into Monday as synoptic scale
lifting increases over the area. Instability looks pretty
limited for any kind of widespread severe chances despite the
strong shear, but would not rule out some stronger storms given
the strong dynamics with this system. Higher moisture will be
over the eastern CWA and our highest QPF totals of 1-2" are
expected there. The front and upper wave will then push through
the area on Monday night with the bulk of the precipitation
shifting east of the CWA by 12Z Tuesday.

Colder temperatures Tuesday into Tuesday night: Colder air will
push in behind this system and highs on Tuesday will only get
into the upper 40s to low 50s. A hard freeze will be possible on
Tuesday night across most of the area and we may need a freeze
warning as we get closer. High pressure should move into the
area on Wednesday with slightly warmer temperatures, but still
below normal for this time of year in the mid to upper 50s.

Warming trend of the end of the week: As the high pressure moves
out of the area, we`ll begin to see some decent low level warm
advection for the end of the week and temperatures should rise
back to above normal in the 60s on Thursday and the 70s on
Friday.

.AVIATION /18Z TAFS THROUGH 18Z SUNDAY/...
Issued at 1211 PM CDT Sat Mar 23 2024

For the 18z TAFS, the large area of stratus which was over much
of the CWA has diminished over the past couple of hours. May
have some temporary MVFR ceilings at the onset of the TAFS, but
should go VFR fairly quick. Winds will become the main aviation
hazard with strong low pressure developing out in the plains.
Gusty winds will start late tonight into the day on Sunday, with
some gusts over 30 kts possible on Sunday.
