Areas affected...northern Illinois

Concerning...Severe Thunderstorm Watch 626...

Valid 160434Z - 160600Z

The severe weather threat for Severe Thunderstorm Watch 626
continues.

SUMMARY...Risk for gusty/damaging outflow winds continues across
portions of northern Illinois.

DISCUSSION...Latest radar loop shows a bowing cluster of
strong/severe storms moving eastward across portions of northern
Illinois at around 40 kt. The strongest convection is crossing
Stark and Peoria counties at this time, and will affect Marshall and
Woodford Counties shortly. The storms are currently moving through
the axis of instability (1500 to 2000 J/kg mixed-layer CAPE per
RAP-based objective analysis), and as such, should maintain
intensity over the next 1 to 2 hours before eventually encountering
a more stable/increasingly capped airmass beginning just west of the
Indiana border. Until then, local gusts in excess of 50 kt will
remain possible.
