.DISCUSSION...
Issued at 211 PM CDT Wed Jul 31 2024

The region remains under the influence of stout thermal ridging
over the central CONUS. However, MCS activity riding the
northeast flank of the ridge continues to impact the EVV Tri-
State this afternoon. Isolated to widely scattered convection
initiated by cold pool outflow boundaries will continue through
tonight. Environment is extremely unstable but weakly sheared.
Main severe risk will be from downbursts causing damaging wind
gusts.

Ridging will build eastward a bit Thursday with 850 mb
temperatures rising to 20-24C across the area. With moisture
pooling ahead of an approaching cold front, heat index values
will have no trouble reaching 105-115F again. Expanded the
ongoing Excessive Heat Warning to include MVN, EVV, and HOP.
Further north and east, maintained the Heat Advisory where heat
index values will be closer to 105-110F. Another round of
thunderstorms will fire Thursday afternoon across the northern
half of the region ahead of the approaching cold front. There
will be a marginal severe risk again, with damaging winds from
downbursts being the main threat.

Following the frontal passage Thursday, seasonable temperature
and humidity levels will return to the region. Synoptic pattern
will feature stout ridging over the western CONUS and troughing
across the eastern CONUS. Might be enough H5 cooling over
southwest IN and the KY Pennyrile to generate a stray shower or
thunderstorm during the heat of the day Friday and Saturday.
Remainder of the forecast period looks to be dry as ridging
slowly increases and high temperatures return to the lower to
middle 90s as a result.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 1045 PM CDT Wed Jul 31 2024

VFR conditions prevail tonight with mostly clear skies across
most of the region. Diurnal heating in the morning will cause
FEW-SCT CU to develop around 3.5 kft AGL. As a cold front begins
to approach from the northwest Thursday afternoon, TSRA will
become possible across all terminals between 17-22z.

There is still uncertainty in how widespread convection will
be, but confidence is slightly higher across the northern
terminals in seeing a storm with gusty winds. By 23-02z Thursday
evening, the latest model guidance has most of the pcpn pushing
off to the southeast giving way to just some scattered high
clouds from northwest to southeast.

Light and variable winds tonight turn SW around 10 kts on
Thursday. A brief isolated gust around 17-20 kts cannot be
ruled out around 20-23z as mixing in the boundary layer will be
a bit deeper. Winds Thursday night are forecast SW between 5-8
kts.
