Area Forecast Discussion

1249 PM CDT Thu May 23 2019

.SHORT TERM...(Today and tonight)
Issued at 353 AM CDT Thu May 23 2019

A warm front will lift north across the region today...bringing
with it the chance for some severe thunderstorms...widespread
rainfall...and warmer temperatures. While most of the area will
start off the day dry...with the light shower activity north of
interstate 80 expected to diminish over the next couple of
hours...as the warm front lifts north and additional moisture
spreads across the area...expect an increase in shower and
thunderstorms activity from south to north. That said...the better
chance for strong to severe thunderstorms will likely come during
the evening and overnight hours...as the nose of the low level
jet aims itself towards southern Nebraska...helping to result in
elevated thunderstorms capable of producing severe hail and
thunderstorm wind gusts. That's not to say that a severe
thunderstorm or two can't be realized during the afternoon hours
today with significant shear in place across the region, but with
meager instability...expect the better chance for severe weather
this evening as the LLJ picks up and the atmosphere further
destabilizes.

Temperature wise...after an unseasonably cool start to the day
with most locations in the lower 40s this morning...expect a
rebound by afternoon with some locations behind the warm front
peaking in the mid-upper 60s. In addition...with already saturated
soils...especially across north central Kansas...decided to
continue the flash flood watch through early Friday morning as an
additional 1 to 2 inches of rainfall are possible in the most
favored locations.

.LONG TERM...(Friday through Wednesday)
Issued at 353 AM CDT Thu May 23 2019

Broad troughiness across the west will maintain an active weather
pattern across the region through at least the middle of next week
with off and on again chances for showers and thunderstorms across
the local area. With these rotating disturbances...there will be
multiple chances for severe weather as well...with parts of the
local area now highlighted in the convective outlook from the SPC
both Friday and Saturday. Temperature wise...expect near to above
normal temperatures through the upcoming weekend...with a modest
drop off to slightly below normal temperatures to start off next
work week.
