.SHORT TERM...
(Tonight through Sunday Night)
Issued at 1122 PM CDT Thu Apr 10 2025

Today proved to be a very interesting day. While we`re still lacking
a sounding from OHX due to hardware issues, ACARS soundings
highlighted an inverted-V setup with plenty of CAPE in the hail
growth zone and relatively dry conditions in the boundary layer.
This set the stage for copious damaging straight line winds and
hail, and we got it. Between the 59 mph measured at John C. Tune
and the 61 mph at BNA, scattered trees and power lines fell
across a good portion of Middle TN with hail in just about every
storm. The largest report was of 1.75 inches in Portland.
Fortunately, we`ve put that stuff to bed for the night and we`ve
been left with mostly clear skies. We`ve got a great weekend
ahead, but not before we see some more showers on Friday as
another impulse rounds the base of the longwave trough over the
eastern half of the country. Forecast soundings aren`t supportive
of severe weather as shear values are barely supportive of
thunderstorms, but with sharp lapse rates and a little bit of
CAPE, the continued cold air aloft could support some small hail
late in the morning and into the afternoon hours. Rains should
come to an end in Middle TN before sunset Friday.

As I said, we`ve got a great weekend on tap. Saturday will be a
little cool, but the boundary layer flow switches to the south on
Sunday and temperatures should climb into the low 70s with quite a
bit of sun.

.LONG TERM...
(Monday through next Friday)
Issued at 1122 PM CDT Thu Apr 10 2025

Our next chance of rain comes into the area Monday evening as an
upper low in the Great Lakes region drags a front through the Ohio
and Tennessee Valleys. The QPF signal isn`t impressive with the
front, but with 50-60 kts of deep layer shear and at least marginal
instability, some thunder will be possible. Details are sketchy
enough to not mention any severe possibility at this point. After
Monday night`s frontal passage, we can expect tranquil conditions
with very pleasant temperatures until Thursday when most long range
guidance suggest yet another round of showers and storms.

.AVIATION...
(12Z TAFS)
Issued at 615 AM CDT Fri Apr 11 2025

VFR conditions prevail at forecast time, but MVFR to IFR cigs will
arrive around 14Z as a weak impulse moves south through the area.
This impulse will produce scattered showers and isolated thunder
today, mainly from 17Z-22Z. Winds will become north with passage
of the disturbance, gusting to 20KT at times.
