...RED FLAG WARNING IS CANCELLED FOR FIRE WEATHER ZONES 008, 009,

The National Weather Service in Topeka has cancelled the Red Flag
Warning. 

Temperatures will cool now that the sun has set and relative 
humidity values are forecast to gradually recover to above 50 
percent this evening. Because of this the fire danger is not as
great as it was earlier in the day. After collaborating with 
partners in land management, there isn't a reason to maintain the 
red flag warning until 11 PM and the warning is cancelled. 

Remember that a wind advisory remains in effect until 5 am Friday
for south winds gusting between 30 and 40 MPH and higher.

Area Forecast Discussion
National Weather Service Topeka KS
641 AM CDT Thu Mar 23 2017

...Update to aviation forecast discussion...

.SHORT TERM...(Today and tonight)
Issued at 233 AM CDT Thu Mar 23 2017

Water vapor imagery showing upper ridge in eastern portions of the
region with upper trough sliding east across the Great Basin. Lower
cloud enveloped the area this evening, though much of Oklahoma
clearing out despite rising dewpoints. Latest KEMP observation
confirming KTWX radar imagery of light precip recently developing
where dewpoint depressions were nearing 10F.

Model soundings continue to be consistent in capping inversion
around 8 kft on top of 3-5 kft of saturation where good veering
profiles exist. This keeps precip in drizzle form, with drying
evident to the south of the state end any mention by midday. With
faster clearing anticipated, have raised highs in the mid to upper
70s. A few lower 80s not out of the question but records in the
upper 80s should be safe. Winds will continue to veer at the surface
with mixing depths increasing. Sustained speeds could approach 30
mph with gusts to around 40 mph in best mixing this afternoon and
again this evening as low level jet returns but Advisory levels look
hard to come by per surface pressure gradient. Will keep small
precip chances going for northwestern areas tonight with convection
likely to fire in far western Kansas late this afternoon and
trajectories giving some chance for this to reach the local area,
and with upper trough emerging into the state late in the night.
Breezy south winds and some cloud should keep lows in the mid 50s to
lower 60s.

.LONG TERM...(Friday through Wednesday)
Issued at 233 AM CDT Thu Mar 23 2017

Potential for showers and thunderstorms on Friday morning add to
uncertainty for severe potential with this system. Despite low
instability, morning storms still have considerable wind in the
column and wouldn't be surprised for strong gusts to mix down with
the morning activity. If this area can get pushed to the east and
allow some clearing/heating for a little better instability to
develop over the eastern counties before the dryline moves into
south central Kansas, then the potential for all modes of severe
weather will increase. At this time, both the GFS and the EC have
the surface low farther to the south, and keep better instability
to the south of the area. If the NAM solution is more on track and
lifts the surface low across the area along I70, then this would
also bump up chances for severe weather. Ample shear is in place
to work with what does develop, so still a bit of a wait and see
for coverage and strength of storms given placement of the low and
northward progress of the instability. Have tracked decreasing
thunder chances west to east through the later evening and
overnight hours. Highs should still reach into the low 70s. Kept
rain chances into Saturday morning and mostly out of our area by
the afternoon save the far eastern counties for precipitation
wrapping around behind the departing low. Highs cool down into the
50s for Saturday.

Remainder of the extended continues to look optimistic for some
rainfall in our area, as another wave moves toward the forecast
area by late Sunday, and another forecast for mid to late week
although timing and strength differences remain. Highs are
forecast near normals in the 60s with overnight lows in the 40s.

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 641 AM CDT Thu Mar 23 2017

Satellite and observations trends from southern Kansas showing
rapid clearing and rising cloud trends and expect VFR conditions
by 14Z at all sites. Quick mixing could lead to a brief return to
MVFR but little confidence in development or persistence for
inclusion. Went ahead with wind shear inclusion tonight given
strong speeds off the surface.
