Then, a front sets up which will start generating more clouds and eventually thunderstorms starting Thursday and lasting through Saturday. This does mean that storms will threaten the fourth of July weekend!
A cold front approaching from the northwest will trigger showers and storms to develop along and ahead of it this afternoon. Some of the storms could become severe and that's why the Storm Prediction Center has areas along and to the northwest of I-44 under a slight risk for severe storms. The primary threats are 60 mph winds, hail up to the size of quarters and heavy rainfall that could lead to flash flooding. 

A tornado watch has been posted for areas north, northeast and east of Springfield. 
A flash flood watch is in effect for all of southwestern Missouri for tonight and early Tuesday.
Anyone living north and west of a line from Lamar to Osceola to Warsaw is under a higher threat of severe weather tonight as the Storm Prediction Center shifts the moderate risk region eastward.
Radar image at 12:36. Cells have been severe-warned with hail up to 1 1/4" reported. Any storms which follow a boundary such as the warm front or any outflow from morning storms will have to be watched for tornado potential.

MONDAY OUTLOOK-DISCUSSION BELOW
SEVERE STORM OUTLOOK FOR TUESDAY
A risk of severe storms and flooding exist today in the Ozarks. The severe part seems a little less volitile tha yesterday's activity but the threat of large hail and damaging winds does exists along with a possible tornado near a front from eastern Kansas to central Missouri.
Watch out today, a 10% plus threat for tornadoes exists from Springfield westward. A stalled front is returning north as a warm front today. This boundary will be the focus for the most severe storms later this afternoon as they develop over Kansas and move eastward during the late afternoon and evening.
Isolated showers and storms will continue to impact the Ozarks through the afternoon hours. Occasional cloud to ground lightning is expected with the activity. This convection will have an impact on temperatures today and it will not be quite as warm as expected. The warmest locations will be across southern Missouri and northern Arkansas. Thunderstorms will develop later today across central and eastern Kansas and track east and northeastward. Northwestern counties in the Ozarks may be impacted by this activity after sunset. Wind gusts to 60 mph and hail up to the size of quarters will be possible.
