.SHORT TERM...(This evening through Saturday night)
Issued at 244 PM CDT Wed Apr 25 2018
The upper low is making slow progress across ern KS at this time,
with lots of light showers rotating around the slow moving system.
System will make slow progress to the E-SE late this afternoon, with
precip ending from NW to SE.
Expect most of the light rain from the departing system to exit most
of the forecast area by this evening. Clearing and subsidence on the
backside of the system will move over the area overnight, with
clearing skies and light winds. This will lead to a nice radiational
cooling for most areas, with min temps falling into the middle 30s
for portions of central KS, especially for areas north of highway
50. Could see some patchy fog across southern ks given the recent
rainfall and temps falling into the lower 40s, with surface
dewpoints still in the lower 40s. Will also add some patchy/areas
of frost for portions of central KS, given that the growing season
has begun with the rapid greenup from the recent rains and temps
falling into the middle 30s. Plan on issuing a Frost advisory for 5
or 6 counties in central KS as well.
The next shortwave (currently located in nrn MT), will drop SE into
the plains by Thu afternoon. This next shortwave will trek
southeast across the plains, but current model trends suggest this
system will come through a little further to the NE than the
previous one. Moisture with this system is rather limited, but
bufkit soundings are alot more saturated/wetter than current model
QPF amounts suggest. So will carry at least a slight pop for light
rain or sprinkles as this system moves southeast. Rainfall amounts
will be very light, under a few hundredths.
Mid level ridging looks to move across the region for the end of the
week into the weekend. As this ridge moves over the area, southerly
winds will return to the area with a warming trend expected for the
weekend with dry conditions.

.LONG TERM...(Sunday through Wednesday)
Issued at 244 PM CDT Wed Apr 25 2018
Mid to upper flow looks to shift to more of a southwest flow pattern
by the end of the weekend into the beginning of next week. This
pattern change will open up the Gulf of Mexico with richer spring-
like moisture streaming northward into Kansas for next week. The
pattern looks to become unsettled for Mon thru Wed, with ingredients
in place for thunderstorms and possible severe weather to affect the
southern/central plains. Latest medium range model projections are
favoring a Tue-Wed period next week for possible active weather, and
this will be a period to watch over the upcoming days.

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1232 PM CDT Wed Apr 25 2018
Aviation concerns will continue to be low clouds/rain today and
fog tonight.
Upper low continues to spin over northeast KS with wrap-around
showers affecting most of northeast KS, getting into the northeast
portion of forecast area. In addition, drizzle has been ongoing
for areas along and east of I-135 this morning with this expected
to continue. May see visibilities reduced to around 3sm with the
drizzle. Should continue to see pockets of IFR ceilings today for
areas along and east of I-135 as ceilings start to lift to VFR
levels from west to east this evening.
May see some fog overnight across the Flint Hills back to as far
west as KHUT. KICT & KHUT look to be the terminals most affected
with IFR levels possible after 08z. This will be due to low
clouds clearing off setting up good radiation cooling conditions.
Moist ground also won`t hurt the fog potential.

.FIRE WEATHER...
Issued at 244 PM CDT Wed Apr 25 2018
Fire weather concerns will remain low across the region for the next
four days due to rainfall today, followed by lighter winds for
Thursday-Saturday. South winds will begin to increase for Sunday
into next week, however the low level moisture will also increase
which should raise the relative humidity levels. The grassland fire
danger levels could reach very high levels during the afternoon
hours on Sunday-Tuesday for mainly central Kansas.
