Area Forecast Discussion
National Weather Service Springfield MO
654 PM CDT Mon Oct 17 2016

.SHORT TERM...(This evening through Tuesday)
Issued at 319 PM CDT Mon Oct 17 2016

It has been an unseasonably warm and windy day across the region.
This evening looks to remain rather windy and quite mild. Winds
should then diminish and veer from the late evening into the
overnight hours as the pressure gradient relaxes with the approach
of the cold front, with the cold front near a central MO far
southeast KS axis by 12z Tuesday. The air mass is currently only
weakly unstable and very capped owing to very warm air aloft and
shallow moisture. There will be a gradual increase in moisture
overnight and also mid level cooling, however even with the front
entering the area in the early morning hours, I don`t see any
great signals for development along the front. If anything there
could be some sprinkles late.

The chance of precipitation will increase some on Tuesday as the
cold front continues to ooze southeastward. Mid level temperatures
will continue to cool and this will allow for improved instability
compared to today along with little if any capping by afternoon.
Given the frontal convergence, there certainly is enough to merit
slight chance pops. The front and clouds will put an end to the
record-ish temps of today, however the temps will remain above

.LONG TERM...(Tuesday Night through Monday)
Issued at 319 PM CDT Mon Oct 17 2016

A stormy and wet period appears to be in the offing early. The
models diverge some on the exact position of the front Tuesday
night into Wednesday, however the general idea is the front will
continue to ooze southeast on Tuesday night and stall. The front
will then waver back northward some on Wednesday with the approach
of the upstream upper trof and migration of a decent surface low
along the boundary. These same factors along with increasing low
level forcing via a southwesterly LLJ and ample instability will
support increasing chances and coverage of showers and
thunderstorms Wednesday afternoon/night both along and north of
the front into the cool sector. The cold front will push through
the area Wednesday night will cooler air invading the region.
While the forecast for Thursday is currently dry, there is the
possibility at least during the morning we may need to eventually
introduce some pops as the digging shortwave remains upstream.

Cool but near average weather will persist on Friday. The pattern
aloft will deamplify some during the weekend into early next week
as the upper trof moves into the western Atlantic. This will bring
a return to a warm advection regime by Sunday and moderating


.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 649 PM CDT Mon Oct 17 2016

Gusty southerly surface winds and low level wind shear will be the
primary flight concern for those headed into the Ozarks overnight.
Winds will begin to taper off towards sunrise as a front begins to
move into the region. This will bring a wind shift through Tuesday
morning for the Joplin and Springfield terminals. Branson will see
a wind shift later in the day Tuesday. VFR to MVFR ceilings will
accompany the frontal passage but no impacts to visibilities are


Issued at 245 AM CDT Mon Oct 17 2016
