Area Forecast Discussion
National Weather Service Nashville TN
255 AM CDT Fri May 8 2020

.DISCUSSION...

The main forecast story continues to be the incoming chilly air
that will bring frost/freeze conditions and possibly some record
lows. See the climate section of the early morning discussion for
more on the specific numbers.

As of 3 AM CDT, showers were starting to develop across our
southwest counties, and the showers will spread across the entire
area by mid morning. Wx maps showed a low pressure center over
north TX with a shortwave and cold front coming down from the
Northern Plains. These features will come together to bring an
average of one half inch of rainfall across Middle Tn today,
followed by a shot of very chilly air. The good news is we do not
expect any thunderstorms or heavy rainfall from this system
today. Winds will be a bit gusty, perhaps over 30 mph at times. We
do not think a wind advisory is needed with speeds staying mostly
below criteria. Also, the times will be limited to a couple of
brief periods- ahead of the surface low mid to late this morning,
then again behind the low mid afternoon.

By this evening, all the showers will be gone and skies will
clear out quickly from west to east as high pressure arrives. It
will take a while for winds to drop off, but they should drop
enough to allow frost formation after midnight as temps drop
through the 30s. Some areas east of I-65 will eventually dip into
the upper 20s by daybreak Saturday! Most of the Mid State will be
covered by a Freeze Warning, except our far west and south
counties where freezing temps will be more localized and brief.
These areas will be covered by a frost Advisory.

After a chilly day on Saturday with highs 15-20 degrees below
normal, another frost/freeze setup will be in place for Saturday
night/Sunday morning. Guidance and model blend numbers look a
little too warm given good radiational cooling conditions. To
avoid confusion with tonight's headlines, we will not issue a
freeze/frost headline yet for that time, but we will mention in
text products.

After the chilly weekend, a quiet week with a gradual warmup is
expected. A few showers are possible at times Monday though Wednesday
for our north half, but no major wx events are expected. High
temps will warm up from the 60s through the 70s and into the 80s
by the end of the week.

&&

.CLIMATE...

This weekend's blast of cold air is likely to break a few records.
Here's a look at some records that might fall Saturday and Sunday:

May 9th

Record Low Temperatures:
Nashville Airport - 37 (set in 1960)
Crossville Airport - 31 (set in 1960)

Record Low Max Temperatures:
Nashville Airport - 57 (set in 1923)
Crossville Airport - 55 (set in 1960)

May 10th

Record Low Temperatures:
Nashville Airport - 37 (set in 1966)
Crossville Airport - 28 (set in 1966)

The latest ever spring freeze at Crossville was on May 28, 1961,
and at Nashville was on April 25, 1910.

&&

.AVIATION...
06Z TAF DISCUSSION.

As our latest weather system approaches from the west, VFR
conditions should hang on for several more hours before the
atmosphere saturates enough to start dropping ceilings. Look for
MVFR conditions to start spreading across Middle TN by 13Z with at
least couple of hours of IFR during the afternoon for all mid-
state terminals. VFR should return Friday evening.

Winds will be gusty today with fropa beginning around 18-19z and
quickly moving through the area. Winds should start relaxing
before 05Z/Sat.
