...AVIATION UPDATE...
.SHORT TERM...(Today and Monday Night)
A pattern conducive to moisture return was ongoing across extreme
southeast Kansas and the Missouri Ozarks this morning. As a
matter of fact, light rain had developed across northeast Oklahoma
and far southern Missouri. Most observations were only showing a
trace, however, this activity will slowly ramp up today and
tonight as deeper moisture return occurs.
An impressive storm system was centered over the Great Basin, and
will continue to approach the Ozarks over the next couple of days.
In response, rain will develop and become widespread across the
region, putting down amounts ranging from one to two inches
through Monday night.
Due to wet antecedent conditions, above average streamflows, and
the lack of vegetation in the winter time, flooding is expected on
some of the more flood prone roads and highways.
A Flood Watch remains in effect for much of the region beginning
today and continuing through Monday afternoon.
Temperatures today will be similar to yesterday, with highs
generally in the 50s. Little cooling will occur tonight with lows
only dropping into the 40s.
And finally, one item to keep in mind is that some isolated
thunder will be possible tonight into Monday. Although I don't
think everyone will hear thunder given the low levels of
instability.
.LONG TERM...(Tuesday through Saturday)
A clipper system will arrive late Tuesday possibly bringing a few
showers and maybe a smidge of snow. The best chances at seeing a
dusting of accumulation will be up toward central Missouri. Most
locations will not see any accumulation. This system will however
bring in some colder air. A nasty day is expected on Wednesday
with highs only in the 30s, under overcast skies and breezy
northwest winds.
Northwest flow in the upper levels will persist through the rest
of the work week and into next weekend, allowing for a few days of
dry and cool weather. Highs on Thursday will warm into the 40s,
followed by 50s on Friday.
The GFS has been suggesting that another long wave storm system
will bring additional widespread rainfall into the Ozarks in about
9 or 10 days from now. Otherwise expected cool and quiet weather
Wednesday - Saturday.
&&
.AVIATION...(For the 12Z TAFS through 12Z Monday morning)
Pilots flying in and out of the southwest Missouri airports will
need to monitor for MVFR flight conditions developing later this
afternoon and into tonight.
Moisture will continue to increase ahead of an approaching storm
system. Rain will gradually increase in areal coverage and
intensity, become widespread by late this afternoon.
Moderate to heavy rain will evolve tonight and linger into Monday.
We could experience some IFR conditions if heavy rain impacts an
airfield directly. Look for surface winds to remain from the
south.
Safe Travels.

Rain and even a few thunderstorms will continue through tonight and linger into Monday. Flooding will become likely late tonight and Monday. .DAYS TWO THROUGH SEVEN...Monday through Saturday.
