07/26/12 Illinois Summer Thunderstorms

Illinois convection ignites along an outflow
boundary northeast of Kewanee, IL

Thursday, made up for some rather "crapvection" the previous night that I was hoping would provide a nice lightning display across west-central Illinois. Mother Nature decided to not cooperate Wednesday night however so I ended up getting a good night's rest as I had hopes of chasing some convection Thursday afternoon in the local-area. During the early afternoon, I was monitoring an area for isolated severe convection across west-central Illinois in Kewanee, IL. It appeared a weak cold front would ignite a few thunderstorms during the late-afternoon in advance of a shortwave trough. This favored-area near Kewanee, IL was characterized by nearly 2,000J/kg of CAPE, 0-6km shear at 30kts, and a moist boundary-layer with dew points around 70°F. Most of the day, I monitored the situation knowing I'd be heading to Peoria, IL later in the evening anyway. I watched storms develop near the Mississippi River. These storms pushed out a nice outflow boundary to their southeast. I was able to watch towers go up along this boundary for nearly a hour. I took some time-lapse video at this point hoping to capture convective initiation. Around 4:00pm, I decided to head north to intercept the first thunderstorm that was a few miles to the north of my parent's backyard. I took a few shots of the outflow boundary showing off the buoyant environment. I was actually very pleased with the visually pleasing convection. After watching the rumbling convection I headed back south to keep up with the outflow boundary that would continue to ignite a few more thunderstorms. I kept up with these storms driving through rural-Stark County, IL as I progressed back to Peoria, IL. It was a route I'm quite familiar with to say the least! I stopped off-and-on near Wyoming, IL along the drive to snap a few photos of the storms that featured many rainbows and some rewarding stormy skies. Unfortunately, we didn't get much in terms of drought relief, but these storms were a nice reward after a pretty lame severe weather year across this area and most of the U.S. Frankly, Canada has stole all our tornadoes as of late if you were wondering! Maybe, it's time to get a passport for next year I think. Anyhow, after snapping a few photos in Peoria, IL during the late-evening I called it a night around 8:30pm. I've added photos and some time-lapse video from yesterday's stroll through rural-Stark County, IL below:

It was another successful evening for photography for myself. I'm still working on my Summer: 2012 post that will have a stockpile of photos I've shot this summer. I'm planning to have that post finished over the next month. More posts to come. Stay tuned.

07/14/12 Summer Convective Updrafts

A gorgeous convective updraft at sunset along
the Illinois River near Peoria, IL

On Saturday, I began a drive back to my hometown of Kewanee, IL shortly after 7:00pm. While I was out and about I stopped to photograph some distant convective updrafts. This convection was along a remnant outflow boundary from previous thunderstorms earlier in the day that formed east of Peoria, IL. These bubbling updrafts were quite picturesque with the low sun-angle near sunset. I primarily used my Canon 70-300mm telephoto-zoom lens to capture the images I've posted below. That lens is one of my favorite lenses anymore, but it doesn't beat my wide-angle lenses though. Anyhow, I shot a few photos before I lost much of my light and later continued my short 40-minute drive across rural-Stark County, IL. I've added a few photos from the late evening below:

It doesn't get much better than that!
 More beautiful colors illustrating the CAPE present

 This boundary didn't really feature much convection, but
yet provided a few photogenic shots...
 Talk about some good contrast...
 Summer instability at its best!
 One more before the sun sets as
the atmosphere began to stabilize...

That will do it for this quick post. With the on-going drought it has left me with lots of free time this summer, but actually I could have used a nice "break" after a busy couple of years so it doesn't bother me too much. In fact, it has allowed me to focus on a few other "projects" I'm currently working on for next spring already...

07/13/12 Wind Farms & Pulse Convection

A local wind farm outside Camp Grove, IL with
pulse convection looming in the horizon...

On Friday, I ventured out during the early afternoon to "chase" a few thunderstorms that were anticipated to develop in the local-area near Peoria, IL. I had the day-off from work so I didn't have too much planned so I decided this would also be another day for some photography. Thursday, I actually was able to get out once again to shoot some photos that I'll be posting at a later date in a rather large (Summer: 2012) post. Stay tuned for that one! Anyhow, around midday I noticed a nice convergent boundary along the Illinois River on visible satellite imagery which would serve the focus for isolated pulse thunderstorm development throughout the day. The area along and south of this convergent boundary was characterized by nearly 2,000J/kg of CAPE, 0-6km shear at an anemic 10-20kts, and a moist boundary-layer with dew points near 70°F. With little of a cap in place to suppress convective development I hit the road shortly after noon at this point already seeing agitated cumulus bubbling up in the eastern horizon. I decided since the risk of severe weather was rather lull that I would use this opportunity to photograph the developing convection at a local wind farm near Camp Grove, IL along the Stark County and Marshall County-border. I watched convection quickly develop to my south for most of the early afternoon and then as anticipated an outflow boundary ignited at my location from the storms to my south. This storm packed some heavy downpours and some vivid lightning. I sat for a good half hour allowing this thunderstorm to give me a nice car wash at this wind farm. Throughout the afternoon I was able to catch a few good photo-ops along the rural Illinois drought-stricken landscape. I've added photos from today's "chase" below:

 I'm about to get a car wash from Mother Nature!
 Bring on the rain!
 The rain dance worked as I picked up 1.00" inch
of rain within around 40 minutes shortly
after taking this photo...

That concludes this post. I'll be posting again some of my best summer photos I've shot over the last few months within the next month. Hopefully, we'll get some more chances for rain as we are now in a severe drought in central Illinois. It has been a dry and hot summer to say the least! Stay tuned for more updates...
