Area Forecast Discussion
National Weather Service Springfield MO
638 AM CDT Sun Aug 30 2020
.SHORT TERM...(Today and tonight)
Issued at 250 AM CDT Sun Aug 30 2020
The cold front that brought severe weather to the region has
moved well south of the Ozarks. However, the 925mb and 850mb
boundaries currently remain over the state line area. North of
the mid level boundary, stratus is in place and based on models,
will remain across the region through the day. This will act to
keep temperatures rather mild today with highs in the middle 70s
to lower 80s.
Across parts of central Missouri and the lakes region, fog had
developed and is expected to linger through mid morning. A dense
fog advisory has been issued for areas that were showing the
lowest visibilities and potential to fall below a half-mile
through this morning.
The mid level (925-850mb) boundaries will also act to provide some
focus for additional shower and storm development through the day.
For the most part, thunderstorm chances will be rather limited but
possible. No severe weather is expected as the best instability is
well south of the area. However, if the rain remains along the
mid level boundaries, some areas may see from a half to an inch of
rain. The best chances for this though is across the the
southeastern portions of the Ozarks, south of I-44 and east of
Highway 65. Despite the rain from yesterday's storms, the region
remains rather dry and flooding is not anticipated.
A few weak upper level shortwaves will move through the upper
level pattern tonight. With the mid level boundaries expected
remain nearly stationary through the overnight, additional periods
of rain will occur through tonight.
.LONG TERM...(Monday through Saturday)
Issued at 250 AM CDT Sun Aug 30 2020
Additional rain is expected through much of the week. Models
bring another front into the region Monday with reinforcing
boundaries impacting the region through Wednesday. An upper level
trough will dig into the southern plains through the first half of
the week which will aid in producing southwesterly flow and bring
ample moisture into the region for shower and storm development.
During the day Monday, there is the potential for a few strong to
severe thunderstorms. Additionally, we may need to watch for
localized flooding by mid week with the expected multiple rounds
of rain despite the recent dry conditions.
The upper level trough will make its way through the Ozarks
Thursday and push the boundaries south and east of the region.
This will bring a rather mild and pleasant day to the region for
Friday as high pressure moves over the area and remains into the
start of the Labor Day weekend.

.AVIATION...(For the 12Z TAFS through 12Z Monday morning)
Issued at 632 AM CDT Sun Aug 30 2020
Cloud cover will remain in place across the region today and
through tonight. Ceilings will remain IFR to MVFR into this
afternoon with showers and a few thunderstorms. Ceilings will
improve to VFR during the afternoon and overnight despite
overcast skies. Increasing chances for sowers and storms will
occur Monday as a front move into the region.
