.SHORT TERM /THROUGH FRIDAY/...
Issued at 300 AM CDT Thu Sep 18 2025
Current Conditions and Synoptic Pattern: Water vapor and upper
air analysis continues to show upper level energy moving closer
to the area from the west. The mid level ridge that has allowed
for the hot temps lately was beginning to finally lose its grip
on the region. 850mb temps on the 00z KSGF sounding were still
high and came in around 20C which is >90th percentile. An area
of showers and thunderstorms was pushing into eastern Kansas
early this morning, likely induced by a mid level vort max, low
level jet and weak elevated instability. Otherwise most of the
area was partly cloudy with temps in the 60s to around 70.
Today: Short term guidance is in decent agreement that the
current activity will move through eastern Kansas and perhaps
into west central Missouri through sunrise before either
dissipating or moving north of the region. Therefore for most
areas the morning hours will be dry and will allow for
destabilization. While there will be increased cloud cover, high
temps should still be able to reach the upper 80s to low 90s
with the highest temps east of Springfield. By mid to late
afternoon, additional lift from the upper levels and an incoming
surface front will allow for scattered showers and
thunderstorms to increase across the area. The 00z HREF
reflectivity paintball plots show a strong signal/consensus for
thunderstorms developing along and either side of the Highway
65 corridor from mid afternoon into the evening and then another
corridor of thunderstorms just west of Springfield sweeping
through the area along the front during the late evening hours.
Forecast soundings do show about 2000j/kg of ML CAPE and
increasing wind shear (20-25kts). Therefore some of the
thunderstorms could be severe with damaging winds up to 60mph
and hail to the size of quarters. Also of note will be the
increasing PW values (up to 1.6in). This will allow for
efficient rainfall production and the HREF LPMM does show
localized pockets up to 2 inches with the storms today.
Overnight: Overall a downward trend of showers and storms will
occur as the front moves in however isolated to scattered
storms still remain possible given the lift and low level jet
over the area. Confidence is low in the current precip chances
overnight into early Friday with additional future adjustments
likely.
Friday: Shortwave energy will largely remain north of the area
during the day and guidance has begun to back off and limit the
amount of redevelopment of showers and storms during the
afternoon and evening. Areas east of Highway 65, closer to the
lingering front may be the area to watch for scattered afternoon
thunderstorm development. Highs will likely be tamped down into
the low to middle 80s, however if more sunshine occurs then
upper 80s will be favored.

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Issued at 300 AM CDT Thu Sep 18 2025
Saturday and Sunday: Ensembles suggest an unsettled pattern will
occur with a more zonal upper level pattern allowing for weak
disturbances to move through the area. Rain chances are
currently lowest during the first half of Saturday with
increasing chances Saturday night through Sunday as a stronger
wave moves through. There also looks to be a low level jet
nosing into the area as well and precip chances have now increased
into the 60-70% range. While it wont rain all weekend, there
will likely be periods or windows of showers and storms which
are hard to pin point at this time range. Instability looks
lower than previous days therefore not currently seeing the
signal for any severe storms. In general, NBM high temps seem
reasonable with many areas staying in the lower to middle 80s
which is closer to average.
Monday through Wednesday: Ensembles have begun to converge on a
pattern shift with a strong upper level low diving southeast
into the central plains early next week. This will not only keep
precip chances going, but will also act to keep seasonable
temps. While current precip chances are around 30-50%, these
will likely increase if the current forecasted pattern pans out.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1240 PM CDT Thu Sep 18 2025
There is increasing confidence in a broken line of thunderstorms
developing somewhere along or east of I-49 after 19Z. For this
reason, included a PROB30 at JLN, though it is possible storms
develop east of the site. There`s a better 60-70% chance for the
storms to impact SGF sometime between 22-02Z. These storms may
be capable of producing wind gusts up to 50 kts and hail up to
the size of quarters, though most storms will produce heavy
rain, lightning, and mildly gusty westerly winds.
After the storms clear, winds are forecast to become light and
southerly, with the 20-40% chance for lingering isolated showers
at all TAF sites, though visibility and cigs should stay VFR for
the rest of the period.
