The National Weather Service wants everyone to be on the alert for funnel clouds this evening.

Don't freak out, this is different  from a tornado watch or warning. The national Weather service has issued an advisory for the following Illinois counties:

    • Winnebago
    • Lee
    • Ogle
    • DeKalb
    • LaSalle

The National Weather service describes the photo above:

Just took these pictures of a funnel cloud that formed along a boundary out in LaSalle County. It is extreme rare for funnels like these to ever reach the ground, so they tend to be harmless. Conditions are favorable for additional funnel clouds to form early this evening generally southwest of a Rockford to Joliet line.

 

According to the National Weather Service:

THE ATMOSPHERIC CONDITIONS ARE FAVORABLE FOR THE DEVELOPMENT OF FUNNEL CLOUDS ALONG A COUPLE OF BOUNDARIES. THESE FUNNEL CLOUDS
NORMALLY PROTRUDE A FEW HUNDRED FEET DOWNWARD FROM THE PARENT CLOUD...ROTATE OR SPIN LIKE A TOP...AND LAST A FEW MINUTES BEFORE DISSIPATING.

THESE FUNNEL CLOUDS RARELY TOUCH THE GROUND AND TYPICALLY DO NOT POSE ANY SORT OF HAZARD. THE ATMOSPHERIC CONDITIONS THESE FUNNELS ARE DEVELOPING IN DO NOT SUPPORT STRONG...DAMAGING TORNADOES. HOWEVER...ON EXTREMELY RARE OCCASSIONS THESE FUNNELS CAN BRIEFLY TOUCH THE GROUND AND PRODUCE VERY MINIMAL...IF ANY DAMAGE.

IF THREATENING WEATHER APPROACHES...MOVE INDOORS TO A PLACE OF
SAFETY. THE NATIONAL WEATHER SERVICE WILL CONTINUE TO CLOSELY
MONITOR THE SITUATION. PLEASE FORWARD REPORTS OF FUNNEL SIGHTINGS TO THE NEAREST LAW ENFORCEMENT AGENCY FOR RELAY TO THE NATIONAL WEATHER SERVICE.

The possibility of funnel clouds will last throughout this evening.
