(1:30PM Friday - 4/15/22) A brief recap regarding the Thur, April 14th high wind event that impacted portions of the region and state.
Overview... The same storm system that brought a severe t'storm risk to the state and region the previous day on Wednesday (April 13th), also brought a high wind event to Northern and Central Illinois, Thursday morning through Thursday evening. This storm system tracked from the Northern Plains/Canada border to the Northern Great Lakes/Canada border on Thursday.
Summary...
Thursday Morning - Thursday Evening, April 14th ~ High Wind Event: As the storm system moved through the region on Thursday, a potent jet streak rounded the base of the associated trough through the region. This will brought a period of high winds to Northern and Central Illinois and portions of the region, Thursday morning through Thursday evening. High winds aloft, characterized by 700MB winds of 45-75KT and a low level jet (850MB) of upwards to 40-55KT, translated across the region. The combination of deep mixing up to around 800MB, along with steep lapse rates and ample sun, aided in transporting higher winds to the surface. During this period, westerly/southwesterly wind gusts of upwards of 35-50MPH to 45-60MPH occurred across Northern and central Illinois, Thursday morning through Thursday evening. Isolated power outages and isolated tree damage also occurred across portions of Northern and central Illinois due to the high winds.

(7:15PM Monday - 2/28/22) A brief recap regarding the Wed-Fri, Feb 23-25th winter storm that brought a swath of accumulating snow/sleet/ice across the region and state during this time.
Overview... A storm system impacted the region Wednesday, Feb 23rd through Friday, Feb 25th, which brought a swath of accumulating snow/sleet/ice across the region and state during this time. Model guidance showed the potential for this winter storm several days out, and in the end this winter storm produced overall very close to forecast expectations. An initial lead wave moved through the Ohio Valley Wednesday through Wednesday night, bringing with it an initial round of wintry precipitation across the southern half of the state. Furthermore, a main storm system developed across the Southern Mississippi Valley Thursday morning, which then tracked near the Ohio Valley Thursday afternoon through Thursday night, and eventually into the Mid-Atlantic by Friday morning. This storm system brought a renewed push of wintry precipitation across the region and state, Thursday morning through Friday morning.
Wednesday Afternoon - Thursday Morning, Feb 23-24th ~ Lead Wave Event:
An initial lead wave moved through the Ohio Valley Wednesday through Wednesday night, with an associated area of precipitation traveling along with it. Precipitation in the form of a mix of freezing rain/sleet/snow pushed across Southern Illinois, Wednesday afternoon through Thursday morning. This period of mixed precipitation brought light accumulations of snow/sleet/freezing rain across Southern Illinois during this time. Thursday Morning - Friday Morning, Feb 24-25th ~ Main Winter Storm Event: As the main storm system moved through the region, an associated renewed push of precipitation also pushed across the state and region, Thursday morning through Friday morning. This renewed push of precipitation, in the form of snow/sleet/ice, moved into portions of Western and Southwestern Illinois mid to late Thursday morning. This area of precipitation then further developed and spread across much of the state from midday Thursday through Thursday night, before ending by late Thursday night and early Friday morning. A transition zone set up much of this period across Central and Southern Illinois. Across this zone, precipitation types from south to north will range from rain across far Southern Illinois to freezing rain to sleet and then to snow across Central Illinois. North of this transition zone across affected areas of Northern and other portions of Central Illinois, all of the precipitation fell as snow. Snow varied in intensity, but was generally light to moderate at times, with snowfall rates of 0.5"+ an hour at times. In additional to the synoptic aspect to this winter storm period, conditions were favorable for some lake enhanced and lake effect snow across portions of Northeast Illinois, Wednesday night through Friday morning. This enhanced snowfall totals a bit for affected areas. Below are map representations of the final forecasts and observed snowfall/sleet and ice totals across the state and adjacent areas. Below are the snowfall and ice forecasts for this winter storm.
Wrap Up...
-An axis of accumulating snowfall with 1-3" totals occurred across Northern and Central Illinois, with higher snowfall amounts of 2-5" across portions Northeast Illinois. -An axis of significant freezing rain/ice accumulations of a 0.10" ot 0.50" occurred across far Southern Illinois. -Scattered tree damage and power outages occurred across far Southern Illinois, due to the freezing rain/ice.

(6:00PM Monday - 2/28/22) A brief recap regarding the Wed-Thur, Feb 16-17th winter storm that brought a swath of accumulating snow/sleet/ice, heavy rainfall with localized to scattered flooding, and an isolated severe t'storm risk across the region and state during this time.
Overview... A storm system impacted the region Wednesday, Feb 16th through Thursday, Feb 17th, bringing a swath of accumulating snow/sleet/ice, heavy rainfall with localized to scattered flooding, and an isolated severe t'storm risk across the region and state during this time. Model guidance showed the potential for this winter storm several days out, and in the end this winter storm produced overall very close to forecast expectations. A cold front moved through the region Wednesday and Wednesday night, associated with a storm system moving through Southern Canada. This frontal boundary became nearly stationary by Thursday morning, near the Ohio Valley in the region and Southern Illinois. Furthermore, a storm system developed in the Southern Plains Wednesday night, and then tracked through the Ohio Valley on Thursday, and eventually into the Northeast on Friday. This storm system brought a renewed push of precipitation and main impacts of this period across the region and state, Thursday morning through Thursday evening.
Wintry (Snow/Sleet/Ice) Aspect Summary...
Wednesday Night - Thursday Morning, Feb 16-17th ~ Cold Front/Lead Wave Event: A cold front moved through the region Wednesday and Wednesday night, associated with a storm system moving through Southern Canada. This frontal boundary became nearly stationary by Thursday morning, near the Ohio Valley in the region and Southern Illinois. Precipitation in the form of rain developed ahead of the cold front, across portions of Missouri, Iowa, Northern/Central Illinois and Wisconsin, Wednesday afternoon. This area of rain continued to expand as it further developed and pushed northeastward, spreading into other portions of Northern and Central Illinois, Wednesday afternoon and evening. This activity continued across Northern and Central Illinois Wednesday night, and also started to push into Southern Illinois as well early Wednesday night, with it then continuing overnight Wednesday night. Isolated to scattered t'storms occurred with this activity across much of the state through Wednesday night as well. Colder air filtered in behind the cold front across Northern and Western Illinois, Wednesday night. As this colder air filtered in, rain transitioned to a mix of rain/freezing rain/sleet/snow across portions of Northern and Western Illinois overnight Wednesday night, which then continued into early Thursday morning. Some minor snow/sleet/ice accumulation occurred across portions of affected areas of Northern and Western Illinois, Wednesday night into early Thursday morning. In addition to precipitation, windy conditions featuring wind gusts of 30-45MPH occurred across the state much of the day on Wednesday Thursday Morning - Thursday Evening, Feb 17th ~ Main Winter Storm Event: As the main storm system moved through the region, an associated renewed push of precipitation moved across the state and region with the main impacts, Thursday morning through Thursday evening. This renewed push of precipitation, in the form of snow/sleet/ice, pushed into Western Illinois by mid morning Thursday. This area of precipitation continued to spread across portions of Northern and all of Central Illinois through late Thursday afternoon, before ending Thursday evening. A transition zone set up and was in place much of the day Thursday across portions of Central Illinois, generally near and between I-72 and I-70. Across this zone, precipitation types will from south to north ranged from freezing rain to sleet to snow. This transition zone eventually changed over to snow for a time, before precipitation ended Thursday evening. North of this transition zone across affected areas of Northern and Central Illinois (Near/north of I-72), most precipitation fell as snow. Periods of moderate to heavy snow occurred at times, with snowfall rates of 1-2" an hour having occurred at times. Additionally, windy conditions occurred Thursday morning through Thursday evening across a large portion of the state. During this time wind gusts upwards of 20-40MPH occurred, which caused some blowing and drifting snow for areas experiencing snow, and near blizzard conditions at times. Below are map representations of the final forecasts and observed snowfall/sleet and ice totals across the state and adjacent areas.
Severe T'Storm Risk/Heavy Rain/Flooding Aspect Summary...
Thursday Morning - Thursday Evening, Feb 17th ~ Severe T'Storm Event: The main risk for an isolated severe t'storm risk existed across far Southern Illinois, Thursday morning into Thursday afternoon. Areas of rain and isolated to scattered t'storms were ongoing Thursday morning across Southern Illinois, in the vicinity of a nearly stationary frontal boundary in place. An isolated severe t'storm was possible with that activity, but none reached that level. As the main storm system moved through the region, an arc of rain and t'storms accompanied the low pressure and cold front that swept across Southern Illinois, Thursday morning into Thursday afternoon. Ahead of this activity, an environment was in place supportive of some severe t'storm risk with this activity. However, in the end the severe t'storm activity ended up occurring just to the south of the state. Wednesday Afternoon - Thursday Evening, Feb 16-17th ~ Heavy Rain/Flooding Event: Persistent periods of rainfall occurred across the southern half of the state Wednesday afternoon through Thursday afternoon, associated both with a frontal boundary becoming stationary across Southern Illinois and the main storm system moving through. During this period of time, periods of heavier rainfall occurred as well. Widespread rainfall totals of 1-4" occurred across the southern half of the state during this period of time, with locally higher amounts. Due to the combination of frost depth/frozen ground and the heavy rainfall that occurred, localized to scattered flooding occurred. Further north across Northern and Central Illinois, rainfall totals of 0.50-2.00" occurred Wednesday afternoon through early Thursday morning, which lead to some instances of localized flooding, due to frozen ground not being able to absorb lingering snow melt and rainfall. Below is a map representation of the observed rainfall totals across the state and adjacent areas. 
Wrap Up...
-An axis of accumulating snowfall occurred across the heart of the state, with snowfall totals upwards of 4-9" in the main corridor. Snowfall amounts quickly tapered north and south of this main axis, across Northern and Central Illinois. -An axis of freezing rain/ice accumulations of a glaze to 0.10" occurred across portions of Central and Southern Illinois, with locally higher amounts of 0.10"+. -An isolated severe t'storm threat was possible across Southern Illinois Thursday morning through Thursday afternoon, however this activity stayed just south of the state. -Widespread heavy rainfall occurred across the southern half of the state, with widespread rainfall totals of 1-4". These rainfall totals will cause localized to scattered flooding for affected areas. -Windy conditions on Wednesday of 30-45MPH and Thursday of 20-40MPH, which caused blowing and drifting snow across the heart of the state on Thursday. -Significant and widespread travel impacts occurred across much of the state, especially across the heart of the state.

This storm system brought a renewed push of precipitation across the region and state, Wednesday night through Thursday night.
Summary...
Tuesday Midday - Wednesday Evening, Feb 1-2nd ~ Overrunning Precipitation Event: A cold front moved through the region on Tuesday, associated with a storm system moving through Southern Canada. This frontal boundary slowed and became nearly stationary across the region and southern half of the state Tuesday night into today. With ample advection of mild/moist air from the south over-topping this frontal boundary, a widespread overrunning precipitation event occurred across the region and state, Tuesday morning through Wednesday evening. Precipitation, in the form of rain, developed and spread across the state Tuesday morning into Tuesday evening. As colder air filtered in on behind the slowing cold front pushing through the state, rain transitioned to a mix and snow across affected areas of Northern and Central Illinois Tuesday evening into Tuesday night. Snow then continued in varying intensity across a large portion of Northern and all of Central Illinois, from transition time through Wednesday afternoon and evening. Periods of moderate to heavy snow occurred at times, with more lull-like periods of lighter snows likely as well. Snowfall rates upwards of 1"+ an hour also occurred at times in the heavier periods of snow, especially Tuesday night through Wednesday morning. Across southern portions of Central Illinois, this is where the overall transition zone set up with mixed precipitation set up Tuesday night into Wednesday morning. Across this zone, precipitation types from south to north ranged from freezing rain to sleet to snow. This transition zone shifted southward Wednesday morning across Southern Illinois, and will eventually stalled out across Southern Illinois during the day on Wednesday. Wednesday Night - Thursday Evening, Feb 2-3rd ~ Main Storm System: As the overrunning precipitation continued across the state into Wednesday evening, the main storm system will also move into the region. A renewed push of precipitation moved across the state and region associated with the main storm system, Wednesday night through Thursday evening. This renewed push of precipitation, in the form of snow, moved into Southwestern Illinois Wednesday night. This area of snow then spread across portions of Central and Southern Illinois, from Wednesday night through Thursday afternoon, before ending by Thursday evening. Periods of moderate to heavy snow occurred at times, with snowfall rates of 1-2" an hour having also occurred at times. Additionally, a period of windy conditions occurred Wednesday morning through Thursday afternoon. During this time wind gusts upwards of 25-40MPH occurred across portions of Central and Southern Illinois, which caused blowing and drifting snow. Further south across Southern Illinois, the transition zone of mixed precipitation was in place Wednesday night through Thursday morning. Across this zone in Southern Illinois, precipitation types from south to north will range from freezing rain to sleet to snow. This transition zone eventually changed over to snow during the day on Thursday, before ending. In additional to the synoptic aspect to this winter storm period, conditions were favorable for a bit of lake enhanced and lake effect snow across portions of Northeast Illinois, Wednesday night through Thursday evening. This enhanced snowfall totals a bit for portions of Northeast Illinois near Lake Michigan.
