.KEY MESSAGES...

- After early morning storms depart, dry and near record warm this
afternoon. Elevated fire danger central KS.

- Shower and thunderstorm chances return Friday PM and last
  through the weekend. Some rain likely for entire area, best
  chance for over 1" across east-central KS.

.DISCUSSION...
Issued at 215 AM CDT Thu Apr 17 2025

As low pressure deepens over the High Plains ahead of the
approaching trough, scattered thunderstorms have developed this
morning in an area of strong 700 mb WAA. These storms are relatively
high-based, with model soundings suggesting bases around 750 mb.
This is limiting effective shear to around 25-30 kts, keeping storms
from becoming too organized thus far. Still, with around 1000-1500
J/kg of MUCAPE and mid-level lapse rates around 8-8.5 C/km (as per
RAP mesoanalysis and the 0z sounding), a hail threat persists with
any stronger and persistent updraft. The main zone of WAA shifts
east of the area by around sunrise, shifting any storm potential
east along with it. The rest of today will be dry and warm, with the
area resting under the 850 mb thermal ridge axis. Strong mixing of
these warm mid-level temps will help temperatures reach 90 across
most of the area. The warmest and driest conditions look to be
across portions of central KS west of a dryline. Combined with gusty
southwest winds, this will lead to very high fire danger in this
area.

Overnight and into Friday morning, a cold front will press southeast
across the area, turning winds to the northwest. This frontal
passage looks mostly dry, given capping from the very warm mid-level
temps. By Friday evening, confidence is high that the front will be
fully through the area. This will keep the main surface-based severe
thunderstorm risk to our southeast. However a few elevated storms
with a marginal hail risk do look likely to redevelop across east-
central KS, where some modest instability remains north of the
front. Weak isentropic ascent north of the boundary continues into
Saturday, supporting at least persistent low clouds and perhaps some
brief light showers. Saturday night into Sunday, the main upper low
lifts northeast across the area. Strong DCVA will support more
widespread showers and thunderstorms. Weak instability should limit
any severe threat, with the main impact being a widespread, soaking
rain. The 50th percentile of 48 hour QPF through Monday morning is
over a quarter inch across all but far northwest portions of the
forecast area, and over an inch across east-central KS. Temperatures
stay cool Saturday and Sunday given the widespread clouds and rain,
around or below 60 degrees.

After a brief break Monday, shower/thunderstorm chances return
Tuesday into Wednesday as southwest flow aloft again sets up. A
couple shortwaves look to move through this flow across the area,
though with plenty of variability in the exact details at this
range. At any rate, southerly flow will help more mild temperatures
return, with highs generally in the 70s Mon-Wed.

&&

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1204 AM CDT Thu Apr 17 2025

Scattered thunderstorms increase in coverage over the next
few hours and move west to east across the terminals, eventually
moving east of KTOP by around 11z. Ceilings with this activity
stay solidly VFR. Winds stay primarily southerly throughout the
day, increasing to around 15 kts with higher gusts during the
day.

&&

.FIRE WEATHER...
Issued at 215 AM CDT Thu Apr 17 2025

Very warm temperatures and very dry air behind a dryline will create
a few hours of very high fire danger across central KS this
afternoon. RH will fall into the 10-20 percent range while southwest
winds reach 15-20 mph sustained with gusts 25-30 mph. Greening up
fuels will limit fire danger some, but any fires that occur with any
still dormant fuels could spread quickly.
