Discussion

Our area remains well in the warm sector today, making it another 
day with above normal temperatures. Smoke continues to move in over 
the region though, hindering some sunlight. Therefore, temperatures 
should max out in the upper 80s again. It is also another breezy 
afternoon, with southwest winds gusting up between 25-30 mph. Winds 
will lighten up some after sunset, but gusts up to 20 mph are 
expected overnight as the cold front starts approaching from the 
north. 

Tomorrow, a deeper shortwave trough will move across the region and 
push a cold front south through our area. The front should reach KC 
around midday, so those north of the front will see high temps in 
the upper 70s to low 80s with those south seeing the mid to upper 
80s again. High res models still show shower and storm development 
along and behind the front starting tomorrow afternoon, but it looks 
pretty isolated to scattered throughout the afternoon and 
evening. There is still a chance for a strong to severe storm or 
two tomorrow afternoon and evening, south of HWY 36. There will be
plenty of CAPE to work with with some decent deep layer shear
overlapping. Hail and strong wind gusts are the main concerns. 
The chance for strong to severe weather will decrease as the sun 
goes down. Shower and storm chances will increase as we approach 
sunset, south of I-70 (along the front). This is when the upper 
level shortwave trough will move overhead. Showers and storms will
gradually move south overnight with the front, exiting the area 
Wednesday morning. Given the front is moving through quicker and 
decreasing rain chances/coverage, rain totals have decreased. Now 
expect up to 0.50 inch of rain, mainly south of HWY 36. 

High pressure will move in behind the front, making Wednesday a 
pretty nice day with mostly clear skies and highs in the upper 70s 
to low 80s. The high will move off the the east quickly though, 
shifting winds back to the southwest Thursday. Warm air advection
will increase across the area, bringing temperatures back to the 
upper 80s to near 90 for the weekend. We don't have any 
appreciable rain chances for the rest of the week, but there will 
be a couple of shortwave troughs that move through the upper 
Midwest bringing rain chances close to the MO/IA border.

VFR conditions expected through the forecast. There is some
potential for LLWS tonight but winds are unidirectional with a 
gradual increase in speed with height. So overall LLWS looks 
fairly marginal given winds at the surface should stay somewhat 
mixed and gusty overnight. A front will move through the area
tomorrow morning, shifting winds to the west and eventually
northwest. Potential for precipitation looks best south of the KC
area so have kept this forecast dry.
