Area Forecast Discussion

655 AM CDT Mon Apr 16 2018
.SHORT TERM...(Today through Wednesday night)
Issued at 155 AM CDT Mon Apr 16 2018
Low pressure over the Upper Mississippi Valley area tonight is
progged to continue moving eastward toward the Great Lakes area
through today. Meanwhile, a mid/upper ridge over the Rockies will
amplify as it develops eastward. Light and variable winds can be
expected across much of eastern Kansas while breezy southeast winds
return to central and western Kansas. This will help boost
temperatures into the 50s and 60s across the area today.
As surface high pressure translates eastward away from the area
tonight, southeast winds will return across the forecast area
resulting in more seasonable lows in the upper 30s to mid 40s.
Tue-Wed...The H85 thermal ridge over the Southern High Plains is
progged to expand north and east across the Central Plains on
Tuesday helping to drive temperatures above normal once again but
this will be short-lived as a progressive shortwave trough emerging
from the Rockies will drive a cold front south across the area on
Tuesday night sending temperatures back to normal on Wed with highs
in upper 60s. Strong northwest winds are anticipated with deep
mixing/subsidence on the southern periphery of the shortwave trough
moving across the Northern Plains.
.LONG TERM...(Thursday through Sunday)
Issued at 155 AM CDT Mon Apr 16 2018
A mid/upper ridge is progged to translate eastward across
the Great Plains on Thu with seasonable temperatures and dry weather
conditions. The next storm system is progged to emerge from the
Rockies late Fri-Sun bringing widespread precipitation to the area.
There appears to be reasonable agreement on the large scale
evolution between the Canadian/GFS and ECMWF while the EMC GEFS
plumes indicate mean precipitation between 1-2 inches across much of
the forecast area. Pops were raised late Fri into Sat as confidence
in widespread rainfall increases.

.AVIATION...(For the 12Z TAFS through 12Z Tuesday morning)
Issued at 655 AM CDT Mon Apr 16 2018
An intense cyclone that is centered over the Lower Great Lakes has
continued to have far-reaching effects as CIGS from ~2,000-2,500ft
associated with the cyclone`s "wrap-around" have festered over the
NE third of KS throughout the night. The SW flank of the Stratocu
deck appears to be slowly retreating as a sharp inverted ridge axis
conts to knife its way from ND to E TX. A such KSLN & KCNU may
occasionally sct thru ~15Z then would be VFR thereafter. The ridge
will shift slowly E later this morning by strengthening troffing
that`ll occur over the Wrn Plains. Winds would become SE ~18Z but
speeds would less than 15kts.

.FIRE WEATHER...
Issued at 155 AM CDT Mon Apr 16 2018
Breezy southerly winds and minimum relative humidities in the mid
and upper 20s will create a very high grassland fire danger across
much of central and south central KS on Tue. A cold front will
bring gusty northwest winds on Wed and although temperatures will
only rise into the 60s, a very high grassland fire danger is
expected once again with minimum relative humidities falling into
the low to mid 20s. An approaching storm system will bring
increasing chances for more widespread precipitation and
decreasing fire weather concerns late in the week and into the
weekend.
