Area Forecast Discussion
National Weather Service Springfield MO
259 PM CDT Sun Aug 13 2017

.SHORT TERM...(This evening through Monday)
Issued at 222 PM CDT Sun Aug 13 2017

Weak upper level wave currently producing scattered light rain
showers across the region. Rain should come to an end as wave
traverses the region and surface high pressure builds in.
Overnight lows will be in the mid 60s region wide.

Monday should be mostly cloudy and dry for the most part. There
will be a slight chance of a shower or thunderstorm primarily along
the Missouri-Arkansas border. Highs should be slightly warmer
than today making into the mid 80s over most locations.

.LONG TERM...(Monday Night through Sunday)
Issued at 222 PM CDT Sun Aug 13 2017

The week looks to be unsettled as the area experiences a pattern
shift from the last week. Start out the period in zonal flow but
by Tuesday ridging begins to take place as an upper level trough
begins to dig along the west coast. This will return the region to
a pattern more typical of mid-August. As winds become more
southerly...warm advection will bring warmer temperatures and an
increase in moisture to the area. By mid to late week...overnight
lows will be in the upper 60s to low 70s while daytime highs will
be just slightly below normal in the mid to upper 80s. With the
increasing humidity...heat index values will once again make it
into the mid 90s with some upper 90s possible along the I-49

With the exception of just a few periods...a least a slight chance
of rain will be possible in nearly every period as weak impulses
move quickly through the upper level flow. The best chances of
rain look to be Tuesday through Thursday. Rainfall amounts will
vary across the area with lightest amounts over central Missouri
and the heaviest amounts over the southwest corner.


.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1203 PM CDT Sun Aug 13 2017

High pressure over the area with a few remnant rain showers
affecting BBG/SGF terminals. Some stratus/strato cumulus over the
area with MVFR conditions which may linger through the day.
Heading into tonight and especially later tonight, may see more
widespread MVFR/IFR conditions develop with lowering ceilings and
the potential of some fog developing as well.
