March 28, 2004 – Chase to Northeast IL

Thanks to my dedication to watch my beloved Illini team lose in the sweet 16 to Duke, I passed up an opportunity to chase on Saturday in the plains. It would have been a good run to W. Oklahoma, but there’s always next time right? 🙂 Anyway, the same system that dropped 7 tornadoes in the Kansas/Oklahoma was heading my way on Sunday and that meant there was a slight chance we’d get something to chase here. Granted the system was weakening, but there was still a chance. The early morning SPC Day 1 outlook showed northern Illinois and southern Wisconsin in a slight risk for severe weather with the main threat damaging winds. (a whopping 2% tornado risk too!) I mulled over the forecast models and initially wanted to target somewhere between Peru and Bloomington Illinois. Unfortunately there was a lot of cloud cover from the leftover storms that was hindering our storm chances. (share the wealth people!)

I continued to monitor the situation throughout the day and there wasn’t much happening. I didn’t want to leave too early and go on some wild goose chase, yet I didn’t want to wait too long and miss something either. I decided to wait for the 2:00pm (20z) Day 1 outlook to see what the SPC was thinking. They ended up shifting the severe threat to eastern Illinois which kind of surprised me a bit. At this time, I started seeing some very small storms go up north of Bloomington and wondered if this was the beginning of the storms. I was ready to leave but not sure where to head. My initial target was too far west and a southern target didn’t have much instability and energy to work with. The best ingredients were along the NE IL/NW IN border, so I decided to head north to my popular destination of Kankakee. (must be a new theme to chase in the same area as many times as possible this year!)

March 20, 2004 – Chase to Southeast Missouri

It seems like this year we’ve had trouble getting our atmospheric ingredients all together. On the Jan 3rd chase, we had decent winds, moisture, but no freaking CAPE or much instability. Today’s setup was the opposite. We had some decent CAPE (1000-1500), instability (LI’s -2 to -6), and moisture (tD’s in the 60s), but very crappy winds aloft. Despite this lack of combined ingredients, I still liked the chances of chasing. My original thought for a target area was Jonesboro, AR., but I would adjust that slightly with data updates throughout the chase. SDS is still kinda bugging me, so I figured what else was there to do other than chase? (well there’s the whole NCAA tourney, but my beloved Illini didn’t play till Sunday)

I got up around 6:00am and got ready to roll. My plan was to leave around 7:00am and head south to my target area of Jonesboro. However, hooking up all the new gear (aka the Chase Live stuff) took a tad longer than I thought, so I didn’t depart until 7:30am. (blasted technology!) I did check some data as I was setting stuff up in the car and noticed ongoing thunderstorms in southern Illinois. (several warnings were issued too) After filling up the gas tank, I headed south on I-57. It seems every time I get around Effingham, I encounter some sort of accident/traffic stopage on the interstate. There was a semi on the shoulder that I didn’t see anything wrong with, yet traffic was completely stopped in both lanes on the highway! Several Illinois State Police units were on scene and I heard them talking on the radio. After a few minutes, traffic started picking back up and I was on my way.

March 1, 2004 – Chase to Northeast IL

Finally, a slight risk somewhere in Illinois! I had been watching this day on the models for the past week. While it would have been nice for this to happen on Sunday, I figured I’d do my best to get a chase in anyway. The Day 1 outlook had northern and central IL in a slight risk with the main threat being large hail and damaging winds. (better than 4-8″ of snow right?!) Unlike my Jan 3rd bust to Missouri, we actually had some CAPE forecasted! (about freaking time!) There wasn’t the nice pool of mid-60 degree dew points to work with, but with the strong low pressure I figured it might still fire something. Unfortunately I couldn’t allocate the entire day to chasing as I had to work, so I had to do what I could with the time after work. Luckily I was able to work through lunch and leave an hour early.

As soon as the clock struck 3:00pm, I bolted out the door and headed home to get the gear. As I was setting up the laptop/GPS, I plugged in the wifi card to get a last minute weather update before heading out. There wasn’t too much on radar other than stuff way up in northern IL and southern WI, which was a tad out of my range for this chase day. I continued to focus on my target area of Kankakee and see what would happen. I finally departed Champaign at 3:30pm and made the trek north on I-57. On the way up, I noticed lots of junk trying to go up but nothing that made me want to stop. As I approached the Kankakee area, I finally encountered some decent amounts of rainfall. For about 5 seconds, I had some small hail pelting the car that got me all excited again. 🙂 I headed north of Kankakee to get out into the country and observed a really spiffy sunlit cloud structure which begged to have its picture taken!

January 3, 2004 – Chase to Southeast Missouri

No this isn’t a typo, I really did chase in January! After looking at the models for days regarding this day, I really wanted to chase. Some ingredients were in place, but like the last chase of 2003 we were missing the beloved CAPE. (must be those darn budget cuts!) Anyway, dew points looked to push into the 60s and temps were pushing mid-upper 60s. (mmm, moisture return!) Luckily this is the weekend I wasn’t scheduled to work, so I was free to chase. The SPC was also watching this area, but wouldn’t go as far as issuing a slight risk. However, they did put a small area of southern Missouri and northern Arkansas in a 2% tornado threat. It doesn’t sound like much, but when SDS is in full bloom you’ll take any positive news you can get! After mulling over the weather data, I decided to initially target the little town of Sikeston in southeast Missouri. I was anxious to see what exactly Missouri would ‘show-me’. 😉

Normally I would never consider a chase like this mainly due to my vehicle issues. However, thanks to the off-season acquisition of a brand new vehicle (courtesy of my chase pal/car salesman Darin Kaiser!), I was able to easily consider chasing today. I got up around 6:00 AM to check data and things still looked promising. (however the SPC still didn’t give me my slight risk!) I loaded up the chase gear and headed out around 7:30 AM. I headed south on I-57 for quite awhile until I hit the rest area south of Salem, IL. After a quick break, I decided to try out my cell phone data connection. I checked radar and satellite and I was still seeing clearing skies in southern Missouri, so that was very good news. I left the rest area and continued my journey on I-57, noting the constant overcast skies with a hint of clearing to my south. I arrived in Sikeston, MO a little after 12:00 PM and decided to stay there for a bit. I grabbed a bite to eat at McD’s (not to be confused with the non-existent mesoscale discussion!) and then utilized my unlimited weekend minutes via my data connection to assess the situation.

May 10, 2003 – Tornado intercept in Western Illinois

What a week of weather across the midwest and plains, but it wasn’t done yet. One more final burst of severe weather was in store before some calm finally rolled in. Would Illinois be in a path for this deadly destruction and wild weather? The SPC certainly thought so when they issued their unprecedented fourth high risk of the week on Saturday morning. The first morning Day 1 outlook just had part of northern and central Illinois in the high risk, with the rest of the state in a moderate risk. Further updates greatly expanded the area of high risk to stretch all the way from northeast Oklahoma to Ohio. The last high risk we’ve had here in Illinois was back in October 24th of 2001 and I remember what happened that day. Given the amount of severe weather throughout the week, I had very little doubt that this high risk would pan out.

The day started off very active with numerous storms moving throughout the state with many being severe and even tornadic. My early attempt to chase these was in vain as they were just too far out of my reach. I then noticed how quickly the skies cleared out and made way for the lovely sun to heat up the atmosphere. While this somewhat provided a cap, I figured that would actually help to get some really good storms late in the afternoon/evening. With my car not in the best of shape, I wasn’t sure I’d be able to chase. While looking at data on the computer, I received a voice mail from Matt Hartman and Joe Walters from INCHASE. They were just west of town here and well in range of the local 2m repeater. They were heading towards Springfield and then would check data from there. As they reached the range of the repeater, we said our goodbyes and I wished them well on their attempt to chase in a high risk area.
