Tuesday Noon Update

Severe weather is likely this afternoon with damaging winds and hail being the largest threat.  A small tornado threat exists but is not the main concern for our area.

The advancing upper level low and slightly negative trough will influence the weather for our area today and tomorrow.  Storms should begin forming sometime later this afternoon and continue through the evening.

Clearing is allowing the atmosphere to become charged and unlike yesterday where there was a strong cap to inhibit convection, today's cap is much weaker and should be broken easily.  CAPE valuse, a sign of instability, are already extremely high for the area.  The significant severe index is also high and you can see some storm activity in Illinois already.

Also the KIND radar is Indianapolis remains offline after a direct lightning hit yesterday.  No word on its return to service.
