I made a tweak to tomorrow's forecast & further detailed the weekend to Tuesday outlook.

Highs today ran near 80 to the mid 80s.  Cold front passed with a few showers & storms mainly in our eastern to southeastern part of the viewing area.

Overnight a few clouds may swing through with cooler lows of 56-60.

With cold air aloft & upper troughiness, cumulus clouds will quickly develop & bubble up over the sky tomorrow.  With a nice, refreshing breeze from the west-northwest then northwest & low humidity, it will feel good outside!  Highs will run 75-80. 

With these cumulus towers really bubbling up, I cannot rule out an isolated shower or two in the afternoon-early evening.

This will be followed by a clearing trends & 54-58 tomorrow night.

Notice the clusters of heavy, even severe storms in the Plains on the periphery of the heat wave to our southwest while we stay comfortable!

Some cumulus clouds will develop Saturday, but lots of high & mid clouds will ride over the top of them.  It will tend to turn mostly cloudy from west to east in the evening.  With virga (rainfall evaporating on the way down), we may be able to get a few sprinkles to showers to the ground in the evening-early overnight hours north of a warm front.  Highs Saturday will run 75-80 with low humidity.

On nose of strengthening low-level jet oriented toward Missouri, numerous scattered showers & storms should pop north of the warm front in that area.  This will occur Saturday late evening-night as any sprinkles to a few showers dry up here.

All of these showers & storms should congeal into perhaps an MCS with heavy rainfall & storms north of the warm front & move southeastward during the night.  Riding in that direction, it should miss most of our area, though some light rain may make it into the southwestern half of the viewing area overnight-early Sunday morning.  Severe weather is possible southwestern Missouri, southeastern Kansas to Arkansas.  Locally-heavy, flooding rainfall may occur St. Louis area & points west & southwestward.

With mostly cloudy to cloudy skies Saturday night-Sunday morning, lows will run near 60 to the lower 60s with that already-mentioned potential of a wave of some light rain in the southwestern half of the viewing area.

A few scattered showers may develop northeast of the warm front Sunday afternoon-evening in our area with partly to mostly cloudy skies.  It will become humid with highs in the upper 70s to around 81.

However, a complex of rain & storms (MCS) will likely blow up along/north of the warm front Sunday night & ride east-southeastward.  On nose of strengthening nocturnal low-level jet, numerous showers & storms should evolve into that MCS.  The heaviest of it will pass southwest of our area late Sunday night-Monday morning (even some severe weather perhaps Oklahoma to Missouri & Arkansas), but a veil of light to moderate rain may overspread much of the area.  This rain may last through the morning with gray skies & temperatures in the 60s to 70.

A break may ensue with highs 75-80 Monday with some dim sun poking through the overcast.

Heavy storms in Arkansas should expand northward Monday night & pretty solid area of steady rain with some embedded storms should overspread a good chunk of the area.

This may last into part of Tuesday before tapering.  Highs Tuesday will only run in the lower to middle 70s, considering the amount of cloud cover & the rainfall coverage around.

A few showers may bubble up Wednesday in the cold air aloft on the backside of our surface low in the overall upper troughiness over the area.  Highs will run the upper 70s to around 81.

Thursday & Friday look dry & warmer with highs 80-85, then 83-86.  Thursday does not look humid, but Friday does.
