Area Forecast Discussion
National Weather Service Topeka KS
654 PM CDT Thu Mar 26 2020

...Update to aviation forecast discussion...

.SHORT TERM...(This evening through Friday)
Issued at 347 PM CDT Thu Mar 26 2020

This morning's cold front has moved south and east of the area, with
a wide range of temperatures currently across the forecast area this
afternoon. Sun has helped temperatures in east-central Kansas closer
to the front reach the upper 60s and low 70s, while northerly winds
and clouds have kept north-central Kansas in the low 50s. Ridging
will build across the Plains this evening, allowing the surface
front to stall along the KS/OK border as a mid-level vorticity max
approaches from the west.

Tonight, an increasing LLJ ahead of the vorticity max will lead to
strong isentropic ascent to the north of our stalled surface front.
With an EML providing steep mid level lapse rates over 7 C/km,
moistening from the isentropic ascent should allow elevated CAPE of
1000-2500 J/kg to develop. Thunderstorms should develop rapidly
between 10 pm - midnight along the northern edge of this elevated
instability, along and east-west axis. Latest trends in the short-
term models have brought this axis slightly farther north, with the
best chances for thunderstorms along and south of I-70. Shear
continues to be impressive, with effective bulk shear in excess of
60 kts. Hodographs above the stable surface layer are generally
straight, allowing for some initially splitting supercells, with
large hail as the main threat. However some slight cyclonic
curvature and the north-south instability gradient should cause the
right movers to be the bigger severe threats. Some of these
supercells could produce very large hail, at or above 2" in
diameter. Given the deep stable surface layer, not concerned with
any tornado threat. Within the stronger cells, a few wind gusts
could penetrate to the surface, but this will be a much smaller
threat compared to the hail. While storm motions will be fast, at
around 50-55 mph to the east, there could be a lower end flash flood
threat if storms are able to train along an east-to-west line. Will
continue to monitor for this potential. Storms should quickly exit
to the east, moving out of the forecast area by 6 am.

.LONG TERM...(Friday night through Thursday)
Issued at 347 PM CDT Thu Mar 26 2020

Most of the day Friday will remain dry, with the exception of a few
showers over northern Kansas, as some weak shortwave ridging builds
in temporarily. Friday evening into Friday night, the deep trough
currently over the southwest CONUS will eject northeastward towards
the Plains, with a strong surface low developing in the lee of the
Rockies. This will allow our stalled surface boundary to once again
lift northward as a warm front. As deep height falls overspread the
area, storms should develop along and ahead of the boundary, mainly
after sunset. With instability and strong shear present again,
another round of severe storms will be possible. The exact degree of
the severe threat will depend on the placement of the warm front.
North of the warm front, storms will once again remain elevated,
with large hail and possibly some gusty winds the main hazards. Any
tornado threat will be confined to along the warm front, where winds
will be backed and any storm can remain surface based. At the
moment, the most likely position of the warm front and any surface
based instability will be along or south of the Kansas Turnpike,
keeping the overall tornado threat on the lower end. However, there
is still a fair amount of uncertainty in guidance of its exact
placement, so the exact degree of the severe threat will continue to
be refined over the next day.

Saturday, the surface low will move eastward across the central
Plains, with a strong pressure gradient developing in its wake. The
pressure gradient along with a deep mixed layer will allow strong
winds to mix down to the surface Saturday evening. Southwest to west
winds of 25-35 should approach wind advisory criteria. The pattern
should quiet down some by Sunday and through the middle of the next
week, with the only system of note a trough moving through the
southern Plains Monday/Tuesday. Guidance is in general agreement
with a surface low track to the south of the area. Thus while there
should be showers and possibly a few storms with this system, not
looking at any significant impacts at this time. Temperatures
throughout the extended period should be seasonable, with highs
generally in the 60s.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 644 PM CDT Thu Mar 26 2020

Stratus will continue this evening with MVFR cigs in MHK and VFR
in TOP/FOE. Main aviation hazard will be the potential for
thunderstorms with the best timing looking to be between 04-06Z in
TOP/FOE, while confidence is a bit lower in MHK. Showers may
linger for a brief period after these push through. MVFR to IFR
cigs will likely continue for the rest of the period, with the
lowest cigs expected during the morning before improving somewhat
during the afternoon. Another round of storms is possible Friday
night, although this looks to occur after this TAF period.
