.MESOSCALE UPDATE...
Issued at 845 PM CDT Tue Sep 16 2025
Stronger convection has now dissipated with the loss of diurnal
instability. A few showers will remain possible tonight, mainly
over the next few hours, within the low level cyclonic flow
regime; however, additional stronger convection is rather
unlikely. Otherwise, seasonable conditions will continue
overnight. /DL/

.DISCUSSION...
Issued at 251 PM CDT Tue Sep 16 2025
Overall, the forecast continues to look warm and relatively dry
for the most part with above normal temperatures and below normal
rainfall.
Through tonight: Isolated thunderstorms will continue to develop
in association with the upper low centered over the southeast
CONUS. Cyclonic flow and lift associated with the low will
continue to interact with and abundance of moisture and
instability to support a few strong to severe storms. The storms
should peak prior to sunset, but a few storms will likely linger
into the evening. /EC/
Wednesday through Monday night: The remainder of the forecast
will see a pattern breakdown as centers of upper-level low
pressure over the Northern Rockies and the eastern CONUS weaken.
Flow across the CONUS should become zonal by the weekend, but
there will still be some opportunity for shortwave trough
amplification that could yield more areal coverage of showers and
thunderstorms possible, especially as the western system pivots
through the central part of the country. Average temps will still
be a little warmer than normal - about 3 to 5 degrees warmer than
normal on most days. /NF/EC/
