Area Forecast Discussion
National Weather Service Wichita KS
329 AM CDT Thu May 24 2018

.SHORT TERM...(Today through Saturday night)
Issued at 325 AM CDT Thu May 24 2018

A summer-like pattern is expected to continue the next several
days, characteristic of above normal temperatures, relatively high
dewpoints/humidity, and periodic thunderstorm chances. Given the
relatively weak flow and forcing aloft, predicting the timing,
location and coverage of these storm chances will be challenging.
Additionally, the overall potential for widespread severe weather
is low given the relatively weak flow/forcing.

Today...Per short-term guidance and latest observational trends,
a mid-level disturbance induced by a decaying thunderstorm complex
currently situated off to the southwest will drift east/northeast
across the region, likely supporting isolated to widely scattered
hit-or-miss thunderstorms from late this morning through the
early evening. Thinking the greatest focus will be generally the
eastern half of KS. Another possible hit-or-miss storm focus today
will be over southeast KS amidst modest mid- level moisture and
an unstable & uncapped airmass. Widespread severe weather is not
expected given the weak flow aloft, although cannot rule a few
strong to severe storms given strong instability.

This evening-tonight...Fairly strong signal from most models
supporting a forward propagating thunderstorm complex moving
east/southeast across portions of Nebraska and generally the
northern half of KS. This makes sense given shortwave energy
currently across the Central Rockies progressing east, along with
decent isentropic ascent along east/northeast fringe of warmer
temperatures aloft. Thinking the greatest threat for severe
weather will be this evening across mainly NW KS, although
isolated severe wind gusts are possible as far east as central and
east-central KS toward midnight with this potential forward
propagating system.

Friday-Saturday night...Friday`s thunderstorm chances will be
heavily tied to the placement of outflow boundaries laid down by
tonight`s storms, which will probably be somewhere across southern
KS and OK. Upper ridge building in from the west should tend to
suppress thunderstorm development by Saturday. Temperature-wise,
above normal atmospheric thickness will support daytime readings
climbing into the 90s for many areas Fri and Sat.

.LONG TERM...(Sunday through Thursday)
Issued at 325 AM CDT Thu May 24 2018

Sunday-Wednesday...Model and ensemble consensus supports shifting
the mid/upper ridge east of the region by early next week, with a
longwave trough continuing to take shape across the western
CONUS. This will allow periodic pieces of shortwave energy to
eject northeast over Mid-America for a return to off- and-on
thunderstorm chances. Modest flow aloft does nudge east some,
which would favor a possible uptick in severe weather potential,
especially across the western half of KS closest to stronger
mid/upper flow. Above normal temperatures mostly in the 90s look
to continue through at least mid- late next week.

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1137 PM CDT Wed May 23 2018

Aviation concern will continue to be overnight storms.

Scattered storms continue to linger across south central KS as
they slowly drift southeast. The intensity has come down over the
last few hours. This activity looks to be sustained by some mid
level moisture transport along with elevated instability. KICT
would have the best chance to see some thunder over the next
couple of hours. Iso-sct storms will again be possible Thu
afternoon as very high instability remains in place. Confidence on
where afternoon convection develops remain low, but there is some
model agreement in storms developing west of I-135, along western
fringes of our forecast area. However, there is a much better
signal for storms Thu night over central KS as some shortwave
energy moves out of the central Rockies.

.CLIMATE...
Issued at 325 AM CDT Thu May 24 2018

Long-range model and ensemble output in concert with Climate
Prediction Center outlooks support continued above normal
temperatures through at least the first week of June, if not
longer.

Also, May 2018 is shaping up to be one of the warmest May`s on
record across the region. Through the 23rd, Wichita is ranked 2nd
all-time.
