.DISCUSSION...
Issued at 140 PM CDT Mon Apr 13 2026

Early this afternoon, water vapor satellite imagery showed an
upper level trough extending from the Great Basin southwest into
southern CA. Broad southwesterly mid level flow of 40 to to 50
KTS was noted from the base of the Southwest US trough,
extending northeast across the Plains, then northeast across the
Upper Midwest and Great Lakes States. A broad upper level ridge
was centered off the FL coast across the eastern Gulf.

At the surface, an area of low pressure was located across the
northeast NE. A warm front extended east northeast across southern
MN. A dryline extended west-southwest across eastern NE, to the far
western counties of the CWA, into western OK. Winds ahead of the
dryline were south-southwesterly at 15 to 25 MPH and gusts to 40
MPH. West of the dryline, winds veered more to the southwest and
dewpoints have dropped down into the mid 30s to lower 40s.

This afternoon and Tonight:

The dryline will move east to a Washington, to Clay center, to
Abilene line late this afternoon. Most CAM soundings do not
show much of cap but weak confluence along the dryline will not
be enough surface convergence to develop thunderstorms. The 3 KM
NAM is showing sfc based storms developing across north central
OK late this afternoon, which may develop northeastward during
the evening hours but most other CAMs do not show any
convection developing along the dryline across the CWA. If
isolated storms were able to develop ahead of the dryline they
would become severe with wind and hail as the primary hazard
given MLCAPES around 2000 J/kg and 35 KTS of effective shear.
The low level winds may be too veered for a tornado threat. but
the probability for storms is below 14 percent across much of
the eastern counties of the CWA. But I may place a 15 percent
chance in Anderson county in case the 3K NAM is accurate with
dryline storms building northeast up towards the southeast
counties. Later shifts may need to update this forecast.

Tonight, as the LLJ increases to 40 to 50 KTS across east central
KS, I cannot rule out a few elevated storms across portions of east
central KS but most of the CAMs do not show storms developing late
Tonight into early Tuesday morning.

Tuesday through Wednesday night:

The upper trough across the southwest US will fill as it lifts
northeast across the Plains Wednesday night.

Tuesday, the dryline will move east across the central part of the
CWA. There will not be as much QG forcing, since the H5 trough will
still be farther west across UT/AZ. The surface shows more
confluence along the dryline, so most of the area will remain
dry. Most CAMs develop surface based storms across northern
OK/south central KS and these storms may move northeast along
across east central KS. The primary hazards will be large hail
and damaging wind gusts but any discrete supercell may spawn a
few tornadoes. However, the low-level wind fields looks to be
veered, so the chances are much lower.

Wednesday afternoon into Wednesday night will provide a better
chance for thunderstorms as the H5 trough shifts east into the
Plains. DCVA ahead of the trough axis will provide for stronger
ascent. At the surface a cold front will shift southeast into the
northern counties and dryline will push east across the southwest
counties. Thunderstorms will develop along the front and possibly
south along the dryline. Some of these storms may be severe with the
primary hazards being large hail and damaging wind gusts. Through the
evening hours a line of storms will congeal along the cold front,
and the threat will become isolated damaging wind gusts. The
front should push southeast of the CWA during the early morning
hours of Thursday.

Thursday through Thursday night:

Early Thursday, an upper level trough will move onshore across the
Pacific northwest and dig southeast into the Great Basin. We may see
a break from any thunderstorms as the Pacific front will push east
into western MO. Frontolysis will occur through the afternoon hours
and westerly winds will diminish and become southerly through
Thursday night.

Friday through Sunday:

The extended range models are in fair agreement. The GFS is a bit
more progressive and maybe more favorable for severe
thunderstorms during the afternoon and evening hours.The H5
trough across the Great Basin will dig east-southeast across
the central Rockies, then across the Plains Friday night into
Saturday Morning. A cold front will push southeast across the
northern High plains, then southeast across NE through the day.
A surface low and dryline across western KS will shift east.
Thunderstorms will develop across central KS through the
afternoon hour. If discrete thunderstorms develop within the
warm sector where there will be sufficient vertical wind shear
and instability for supercell thunderstorms. The hazards from
supercell thunderstorms would be large hail, damaging wind
gusts, and possibly a few tornadoes. It still remains uncertain
if these discrete supercells will remain south of the area
Friday afternoon. Though the slightly more progressive GFS
solution would provide a better chance for supercell
thunderstorms developing ahead of the cold front/dryline during
the afternoon hours before the storms congeal into a squall
line. The slower ECMWF solution shows most storms developing
ahead of the cold front during the mid and late evening hours.
If a line of storms develop the the primary hazard would be
isolated damaging wind gusts along the squall line. The cold
front will move southeast of the CWA during the morning hours of
Saturday and the rain and thunderstorms will shift east of the
area. We will see a cool down by the weekend with highs in the
mid 50s north to lower 60s south. Highs Sunday will be in the
lower to mid 60s. Low temperatures early Sunday morning may fall
below freezing across the northern counties of the CWA with mid
30s across much of the area. Therefore, a freeze warning and
frost of advisory may be needed Saturday night into Sunday
morning.

An H5 ridge will move towards the Plains next week, which will cause
temperatres to warm into the 70s on Monday and the 80s by the middle
of next week.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 520 PM CDT Mon Apr 13 2026

VFR at all TAF sites through the TAF period with gusty southerly
wind. Some thunderstorms have developed down near Emporia, but
confidence in these making it into the Topeka area are too low
right now to place any mention in the TAF.

&&

.FIRE WEATHER...
Issued at 340 AM CDT Mon Apr 13 2026

While green up of vegetation is underway, a Red Flag Warning
will continue across north-central KS, where gusty winds and
low RH will combine to create extreme fire danger. Dew points
are forecast to drop this afternoon in this area as a dryline
moves east. Minimum RH behind the dryline could quickly fall to
around 20 percent. South-southwest winds will be sustained at 15
to 20 mph with gusts as high as 30 mph throughout the
afternoon. Similar conditions will be in place behind the
dryline (mainly in central KS) on Tuesday, with minimum RH
between 20 and 25 percent and continued gusty south-southwest
winds. Fire headlines are not currently anticipated Tuesday.
However, at this time the Range Land Fire Index has only a very
high fire danger for north central KS. All Burning should be
postponed through midweek.
