...New UPDATE...

.UPDATE...
Issued at 905 AM CDT Sun Jun 9 2024

At 9 AM CDT, Middle TN was pretty much rain-free, but more showers
and scattered storms were observed upstream, across western TN/KY
and back into MO. The next batch of showers and embedded thunder
will move from west TN?KY late this morning through midday,
impacting mostly along and north of I-40. No severe storms are
expected through lunchtime, just some brief downpours. and
scattered lightning strikes.

Going into the mid and late afternoon, scattered showers and
thunderstorms will develop area-wide as a cold front drops into
the Mid State. There will be more instability, so a couple of
stronger, perhaps briefly severe storms with gusty winds, frequent
lightning and heavy downpours may occur. Passage of the front
will shut of rain along and north of I-40 around 8 or 9 PM while
areas to the south will keep shower and storm chances until
midnight. Look for patchy fog late tonight as skies start to
clear.

.SHORT TERM...
(Today through Monday)
Issued at 115 AM CDT Sun Jun 9 2024

Existing boundary over the region will sink southward during the
afternoon, allowing for more showers and thunderstorms to develop.
Southwest flow to the south of the front will bring additional
heat and moisture to the mid state, increasing instability. Deep
layer shear will remain strong, especially with a shortwave
trough moving through during the day. This will allow for some
strong to severe storms to develop during the afternoon, with the
main threat being damaging wind gusts. However, PWAT values will
be high, allowing for heavy rain and a potential flooding threat
especially with any stronger storms training over localized areas
this afternoon. Showers and storms should continue southward with
the front and be out of the mid state around midnight or so.

A drier period moves in after that to start the week, with a
Midwest trough swinging southward Monday but looking dry at the
moment. CAA will keep high temps in the mid 70s to around 80 on
Monday.

.LONG TERM...
(Monday Night through next Sunday)
Issued at 115 AM CDT Sun Jun 9 2024

Ridging looks to work its way in for the remainder of the
week, with a warming trend through the week as well. Afternoon
showers and storms may work their way back into the forecast
Thursday into the weekend, but high temps will be in the low 90s
Thursday through Sunday. Long term ensembles suggest a Plains
trough could move in later on Sunday into early next week, along
with remnants of a tropical low from the Gulf, so the drier period
looks to only be in place for this week. Either way, it looks like
the heat of summer will finally arrive later this week.

.AVIATION...
(12Z TAFS)
Issued at 620 AM CDT Sun Jun 9 2024

MVFR cigs are expected to spread across the area this morning and
into the afternoon. Isolated showers are possible this morning
before becoming more scattered in coverage after 17Z. Visibilities
may lower at times during periods of heavier rain. Otherwise, W/SW
winds will become N/NW this afternoon behind a front. Improvement
back to VFR is possible after 00Z once rain chances diminish.
