.DISCUSSION...
(This evening through next Thursday)
Issued at 204 PM CDT Fri Jun 20 2025

Heat, humidity, and afternoon storms will be the main weather
concerns over the next several days as a pesky upper level ridge
parks over southeast CONUS.

Temperatures will climb into the low and mid 90s Saturday and
Sunday, with dewpoints reaching the mid and upper 70s. An areawide
Heat Advisory will go into effect at 11AM Saturday as heat index
values exceed 105 degrees. Due to the modeled persistence of the
aforementioned ridge, additional heat headlines will be needed
through the majority of next week. Attempted to draw up a
multi-day Heat Advisory to capture this threat, but opted to only
issue a heat product for tomorrow after collaboration with
surrounding offices.

One caveat to the heat forecast is the potential for afternoon
showers and storms each day. Both the GFS and ECMWF depict weak
shortwaves traversing the periphery of the upper level ridge. This
would provide enough support to kick off thunderstorms in the
afternoons. Upscale storm growth will be severely limited due to
lack luster shear and lapse rates. Therefore, no severe weather
is anticipated at this time. Instead, expect pop-up storms in the
afternoons with potential for gusty winds and perhaps small hail.

VFR forecast with isolated afternoon thunderstorms/showers. VFR
conditions are currently present across the Midsouth with some
orphaned cirrus aloft. These conditions will persist through
tomorrow morning with winds out of the south-southwest. Some
thunderstorms are possible during the afternoon hours at
MEM/MKL/TUP, but forecast confidence is low at this time on
coverage. Any storms/showers will dissipate after 00z with VFR
continuing through the end of the period.

.FIRE WEATHER...
Issued at 204 PM CDT Fri Jun 20 2025
