(10:30AM Wednesday - 4/13/22) A storm system moving through the region will bring a severe t'storm risk to the state, this morning through this evening.
Summary... With this update we have adjusted the level 2 and 3 severe t'storms risks southward a bit across the state. This change was made based on real time observations, supporting the best severe t'storm risk to be a bit further south than previously expected. A storm system tracked through the Central Plains on Tuesday, and will be moving through the Midwest today, and then into Canada on Thursday. This storm system will bring a severe t'storm risk to the state and portions of the region, this morning through this evening.
Forecast...
This Morning - This Evening, April 13th ~ Severe T'Storm Event: A complex scenario is expected today, with the main threat for an isolated to scattered (levels 1-3) severe t'storm risk will exist across the state this morning through this evening. Several pockets of scattered showers and t'storms have been moving across the state this morning. Some of this activity is remnants of a line of showers and t'storms that moved across Iowa and Missouri Tuesday night, with other activity associated with a disturbance moving through the Ohio Valley. As anther disturbance pushes northeastward through the region, regeneration and development of new showers and t'storms has occurred this morning across portions of Missouri, Oklahoma, Arkansas and Texas. This activity is in the process of developing into a broken squall line (QLCS), with is expected to then push northeastward, sweeping across Central and Southern Illinois this afternoon and evening. The environment expected to be in place ahead of this activity as it pushes across the state, will be favorable for some severe t'storm threat across portions of the state. The environment that will be in place will feature low to moderate instability of 500-2,500J/KG, dew points in the low to mid 60's, good shear, good forcing, and good lapse rates of 6.0-8.0C. This environment will be supportive of upwards of an isolated to scattered (levels 1-3) severe t'storm risk across the state. All modes of severe weather will be possible, which includes; large hail, damaging winds and tornadoes.

Wednesday Morning - Wednesday Evening, April 13th ~ Severe T'Storm Event: A complex scenario is expected on Wednesday, with the main threat for an isolated to scattered (levels 1-3) severe t'storm risk will exist across the state, Wednesday morning through Wednesday evening. Along and ahead of an eastward moving cold front, a left over broken line of isolated to scattered showers and t'storms from Tuesday night will be ongoing across portions of Wisconsin, Iowa, Northwest/Western Illinois and Missouri early Wednesday morning. This activity is expected push eastward through the morning across portions of Northern and Central Illinois. As anther disturbance pushes northeastward through the region, some regeneration and new development of showers and t'storms expected along the cold front from mid Wednesday morning into early Wednesday afternoon, across portions of West-Central/Southwest Illinois and Missouri. This activity will then sweep northeastward across the state, from midday Wednesday through Wednesday evening. The environment expected to be in place ahead of this activity as it pushes across the state, will be favorable for some severe t'storm threat across portions of the state. The environment that will be in place will feature low to moderate instability of 500-3,000J/KG, dew points in the low to mid 60's, good shear, good forcing, and good lapse rates of 6.5-9.0C. This environment will be supportive of upwards of an isolated to scattered (levels 1-3) severe t'storm risk across the state. All modes of severe weather will be possible, which includes; large hail, damaging winds and tornadoes. One thing to watch as it pertains to the extent and quality for severe weather risk, is the possibility for widespread cloud/shower/t'storm activity throughout the day across the state and region. This could limit the severe t'storm potential a bit if the effects are too overpowering.

Wednesday Morning - Wednesday Night, April 13th ~ Severe T'Storm Event: A complex scenario is expected on Wednesday, with the main threat for an isolated to scattered (levels 1-3) severe t'storm risk will exist across the state, Wednesday morning through Wednesday night. Along a cold front, a left over broken line of rain and t'storms from Tuesday night will be ongoing across portions of Wisconsin, Minnesota, Iowa and Missouri early Wednesday night. This activity is expected push eastward through the morning. As anther disturbance pushes northeastward through the region, some regeneration and new development of showers and t'storms expected along the cold front from Wednesday morning into early Wednesday afternoon, across portions of Wisconsin, Northwest/West-Central/Southwest Illinois and Missouri. This activity will then sweep northeastward across the state, from midday Wednesday into early Wednesday night. The environment expected to be in place ahead of this activity as it pushes across the state, will be favorable for some severe t'storm threat across portions of the state. The environment that will be in place will feature low to moderate instability of 500-2,500J/KG, dew points in the low to mid 60's, good shear, good forcing, and good lapse rates of 6.0-8.5C. This environment will be supportive of upwards of an isolated to scattered (levels 1-3) severe t'storm risk across the state. All modes of severe weather will be possible, which includes; large hail, damaging winds and tornadoes. It should be noted that there are two things to watch that could impact the quality of the severe t'storm risk... The timing of the cold frontal passage is one thing to watch, as earlier timing would limit the severe risk across portions of the state, and slower timing would be more favorable for the severe risk. Also, a disturbance moving up through the Ohio Valley early in the day on Wednesday could hinder the overall severe risk should it track further north or slower.
