.SYNOPSIS...
Issued at 305 AM CDT Fri Apr 21 2017

As a stationary frontal boundary sits just south of our region
through late tonight and into early Saturday, waves of rainfall
will continue to develop across the central plains and push
through our area. With each round of rainfall, flooding concerns
will gradually increase, especially south of the HWY 54 corridor.

Gradual clearing can be expected by late weekend and into early
next week. After a few days of pleasant weather early to midweek,
more unsettled weather is anticipated.

&&

.SHORT TERM...(Today through Saturday)
Issued at 305 AM CDT Fri Apr 21 2017

Showers and a few embedded thunderstorms have developed across
southeast Kansas and the Missouri Ozarks early this morning. This
activity is forecast to continue to develop/expand eastward
through the morning. A series of upper level disturbances should
keep precipitation going through much of the day. A less subtle
wave will then eject from the Rockies and into the southern plains
this afternoon. There may be a very slight break in the rainfall
late morning/early afternoon (respectively), however, with the
evolution of the waves, think that any break will be short-lived
before additional showers and storms develop/expand into the
region from the west.

From a severe weather standpoint, there will be just enough
elevated instability and wind shear or a hail/gusty wind threat,
however, the main story with this storm system will likely be the
potential for flooding (see below).

Eventually, a surface low with its parent mid level wave will
shift eastward during the morning Saturday. This should push the
heavier rain off to the east. Although much of the heavier
rainfall moves east, we will still be left with some light rain
showers/drizzle. It will also be noticeably cooler with some
locations not even getting above 50 degrees.

In terms of storm totals, most short term and global guidance have
increased amounts across the I44 corridor. Went ahead and added
Bourbon and Vernon Counties to the Flood Watch due to receiving
around an inch of rain yesterday with an additional 1-2 expected
up that way before all said and done. Around the I44 corridor and
especially south, think rainfall amounts of 2-4" with locally
higher amounts (say 5") is still reasonable. With soils becoming
quickly saturated (if not already) flooding concerns will grow
with each wave of heavier rainfall through today and especially
into the evening/overnight tonight.

.LONG TERM...(Saturday night through Thursday)
Issued at 305 AM CDT Fri Apr 21 2017

Precipitation and eventually clouds should slowly start to
decrease as the pesky late week system continues to exit stage
right by Sunday. Upper level ridging is then expected to build over
our area next week. This will allow temperatures to warm back
into the normal range after a below average weekend.

The weather once again turns unsettled mid to late week next week
as another series of mid level waves move from the southern
plains and into our region. At this time, timing and exact impact
of each wave are still difficult to resolve, however, this looks
to be a decent opportunity of more showers and thunderstorms
through perhaps early next weekend.

&&

.AVIATION...(For the 12Z TAFS through 12Z Saturday morning)
Issued at 653 AM CDT Fri Apr 21 2017

An area of rain and embedded thunderstorms will continue across
southern Missouri early this morning. Additional rounds of showers
and thunderstorms will then impact the area from later this
morning into tonight. MVFR and local IFR conditions can be
expected around storms. IFR will become more prevalent from this
afternoon into tonight.

Surface winds will increase and become gusty out of the east from
this afternoon into tonight.

This Hazardous Weather Outlook is for portions of the Missouri
Ozarks and extreme southeast Kansas.

.DAY ONE...Today and Tonight.

Weather hazards expected...

  Elevated Hail risk.
  Limited Thunderstorm wind damage risk.
  Elevated Flooding risk.
  Elevated Lightning risk.

DISCUSSION...

Moderate to heavy rain and scattered thunderstorms will impact
the outlook area today. Heavy rainfall will become more
widespread this afternoon and evening. Storm total rainfall will
range from two to four inches through Saturday with localized
amounts near five inches. The excessive rainfall will result in
elevated risk for flooding of streams, poor drainage areas, low
water crossings and main stem rivers.

In addition to the flooding risk, a strong storm or two with hail
may develop along the Arkansas border this afternoon.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.

Residual flooding will be possible during much of the day
Saturday from heavy rainfall on Friday.

Our next storm system will set up across the central plains by
mid week next week. Additional showers and thunderstorms will be
possible during this timeframe.

.SPOTTER INFORMATION STATEMENT...

  Spotter activation will not be needed through tonight.
