.SHORT TERM /THROUGH TONIGHT/...
Issued at 230 AM CDT Tue Jul 16 2024
Upper air analysis shows a positively-tilted upper-level trough
centered over Ontario moving southeast. Convection is firing in
western Kansas and Illinois. At the surface, a cold front is
situated to our northeast, by the border with Kansas, Nebraska,
and Iowa. This front is moving slowly southeast. Temperatures
are currently around 80 with some scattered clouds.
As the cold front continues to move to the south, model guidance
suggests thunderstorms will develop across north-central Missouri
and move south as the LLJ noses into western Missouri. Recent CAM
runs show some support for these storms moving south across our
area, which will come with a risk for elevated convection. Some of
these storms may produce hail of one inch or less, and some locally
heavy rainfall.
Some of the storms from this morning may linger into the afternoon,
but the highest chances (50-80%) for storms will be from the late
afternoon into Wednesday morning, as the LLJ again creeps into
southwest Missouri from Oklahoma and Arkansas. High resolution
models show MLCAPE values of 2500-4000 J/kg across southern
Missouri. Shear on the other hand is rather modest, so the main
severe hazard will be strong winds. The Storm Prediction Center
currently has our entire CWA under a Marginal Risk (Level 1 of 5)
for severe weather. A stalled surface low to the southwest in
Oklahoma may allow multiple rounds of storms to go over the same
areas. This brings with it a risk for flash flooding. A flash flood
watch has been issued from 7 PM Tuesday night until 7 AM Wednesday
morning, primarily for areas to the east of Highway 65. 48 hour HREF
PMM guidance indicates that localized areas of 3-5" of rain are
possible, so be sure to practice flood safety tonight.
Temperatures today will range from around 90 to the upper 90s, with
temperatures increasing the further south you go. A heat advisory is
in effect until 8 PM for all but 3 of our counties. Given the
uncertainty of morning storms, and increased cloud cover compared to
yesterday, high temperatures were forecast today using a blend of
the NBM deterministic forecast and NBM 25th percentile, so on the
lower end. However, if there are less storms, or less cloud cover,
heat indices can still easily reach 105 to 110 degrees in our
southern counties given the continued humidity. Lows tonight will
reach the low 70s.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 230 AM CDT Tue Jul 16 2024
Behind the passage of the cold front, high temperatures fall to the
low to mid 80s on Wednesday. This will usher in a period of cooler
and drier conditions. The 6-10 day Climate Prediction Center
Temperature Outlook has our area at a 60-80% chance of below average
temperatures, with highs consistently in the 80s and lows in the 60s
for the next few days. Precipitation chances remain under 20% until
Sunday, as long range forecast models are beginning to pick up on
some shortwave energy moving into the area.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 606 AM CDT Tue Jul 16 2024
Thundershowers are possible much of the day today. Starting with
this morning, a few isolated thundershowers are possible at JLN
and SGF, although confidence is not high enough to include in
the TAFs at this time. Most morning storms should stay north of
TAF sites, although some light rain from eastern Kansas may
reach Joplin this morning as well.
Moving into this afternoon, some difficult to predict pop-up
storms may occur. More widespread storms are likelier this
evening into Wednesday morning. Storms which do form will lower
ceilings and visibilities to MVFR conditions. Windspeeds will
decrease from around 10 knots to 5 knots this evening as a cold
front moves south. As this happens, southwesterly winds will
become variable for a bit before eventually shifting to more
northwesterly.
