Light to moderate snow will continue into Saturday over the Great Lakes, Central Appalachians, and Northeast. This weekend into next week, a series of atmospheric rivers will bring gusty winds, periods of heavy rain, and mountain snow to northern California and the Pacific Northwest. Colder temperatures are in store for the weekend from the Great Lakes to East Coast. Read More >

Overview and Science
A potent upper level disturbance interacted with a very warm and moist air mass on Wednesday afternoon and evening, and this lead to the development of severe thunderstorms. The images below are water vapor images from the weather satellite. These images indicate the amount of water vapor in the upper atmosphere. This allows us to see the strength and placement of weather disturbances in the atmosphere. In the images below you will notice the orange colors marked with the red arrow. This is an indication of a mid-level jet streak (a band of stronger upper level winds) associated with a significant upper level disturbance. The right hand figure, taken about 30 minutes after the left image, shows rapid thunderstorm development. The updrafts associated with the thunderstorms lift large amounts of water vapor into the upper atmosphere, which is detected here by the satellite. Overall, the approach of this upper level disturbance dynamically induced cooler mid-level temperatures due to increased forcing for ascent. This process allowed the cap to erode and thunderstorms to rapidly develop across north central Illinois. The cap is a basically a corridor of warmer temperatures aloft which act as a lid in the atmosphere, keeping thunderstorms from developing.

Satellite Water Vapor Image from 2:52 PM Wednesday Afternoon. Notice the Orange colors marked by the red arrow from the Dakotas southeastward across Iowa. This is an indication of stronger upper level winds associated with a significant upper level atmospheric disturbance. |
Same as the left image, except this image was taken at 325 PM only 30 minutes later. Notice all the blue and green areas across north central Illinois and into Wisconsin. This is showing the rapid development of thunderstorms. What this represents is a vast amount of water vapor being lifted into the upper atmosphere by the strong updrafts of the storms. |

The radar imagery here starting at 3:35 PM and running each hour through 6:30 PM shows that once thunderstorms developed, they rapidly became severe. The very unstable atmosphere combined with a good amount of wind shear (changes in wind speeds and direction with height) allowed these storms to become super cellular. A super cell is severe thunderstorm characterized by a rotating updraft. Super cells are typically the thunderstorms that associated with tornados. However, they are also known for producing large hail and strong winds. These storms prompted several warnings, including for tornados as they moved eastward towards the western suburbs of Chicago. Survey teams will be going out today to study to some of the damage to determine if any tornados occurred. |

These radar images during the late afternoon and evening indicate that the thunderstorms began to train from west to east over the same areas. These storms produced heavy amounts of rain on the order of 1 to 2 inches per hour and this lead to flash flooding across portions of the area. |

Click images for loop. This loop depicts how several individual cells, mainly with supercell structure at first, morph into a larger complex with segments that quickly propogate forward. These are the portions of the storms where strong winds were present, which were realized at the surface in places. Clear inflow and rotation was seen early on, which included the Shabbona area tornado. This would keep some semblence eastward in far southern DeKalb County and then re-intensify south of Plano, where numerous wall cloud and funnel cloud reports were received. This includes the one below. |

As a reminder, plese think safety first when viewing thunderstorms and if under a warning or sensing immediate dangerous weather conditions, seek shelter immediately.

* DISCUSSION/DAMAGE:
NATIONAL WEATHER SERVICE PERSONNEL SURVEYED DAMAGE IN EASTERN
LEE...SOUTHERN DE KALB...AND KENDALL COUNTIES OF ILLINOIS. THE
SURVEY TEAM DETERMINED THAT MUCH OF WHAT THEY FOUND WAS STRAIGHT
LINE WIND DAMAGE...BUT ONE AREA SOUTH OF SHABBONA IN SOUTHEAST DE
KALB COUNTY WAS CONFIRMED TO BE A TORNADO.
THE MAXIMUM DAMAGE OCCURRED OVER AN APPROXIMATELY ONE MILE LONG SEGMENT OF THE PATH WHERE THE TORNADO SNAPPED NUMEROUS UTILITY POLES AND AROUND 80 PERCENT OF THE LARGE HARDWOOD TREES. THIS AREA COINCIDED WITH THE SOUTHERN END OF SHABBONA LAKE STATE PARK ALONG SHABBONA GROVE ROAD. ALONG THE REMAINDER OF THE TORNADO PATH THERE WAS MINOR TREE DAMAGE. MINOR SHINGLE PEELING WAS SEEN AT ONE LOCATION...BUT FOR THE MOST PART THE TORNADO DID NOT INTERSECT ANY STRUCTURES.
THIS TORNADO PATH ALSO WAS COINCIDENT WITH A NEARLY MILE-WIDE SWATH OF LARGE HAIL THAT PRODUCED EXTENSIVE SHREDDING AND SMASHING OF CROPS. ADDITIONAL INFORMATION ON THE WIND DAMAGE IN THIS AREA WILL BE PROVIDED AS IT BECOMES AVAILABLE. THE DAMAGE WAS SCATTERED AND CONSISTENT WITH MAINLY 60-80 MPH WINDS. THIS INCLUDED ABOUT A HALF DOZEN GRAIN BINS DENTED AND NUMEROUS LARGE TREES DOWNED. THIS PRELIMINARY INFORMATION WAS DETERMINED BY NATIONAL WEATHER SERVICE SURVEY TEAMS AND IS SUBJECT TO CHANGE PENDING FINAL REVIEW OF THE EVENT AND PUBLICATION IN NATIONAL WEATHER SERVICE STORM DATA.

Not much damage, but ironically this is NWS observing equipment in Shabbona Lake State Park which was titled by the winds near the EF-1 tornado. |

Hail damage to crops. The lack of visible crop in the immediate forefront fields help to show that. Note the fields in the distance are more green and full. When examining these crops in the foreground up close, they were shredded and smashed, with no leaves giving this appearance above. |
