.NEAR TERM...(Tonight)
Issued at 111 PM CDT Mon Jun 21 2021
Heating continues this afternoon, resulting in MLCAPE values of
2000-2500 j/kg. This has resulted in spotty small shower development
thus far in north AL and southern TN. The area is between two main
areas of moisture transport and more organized deep convection. A
band from northern MS through central AL will work its way northeast
into our area over the next few hours. The other area is along and
ahead of a cold front northern KY through northeast AR. This area
will arrive this evening from northwest to southeast. How far
southeast this maintains full intensity is still uncertain, but will
maintain the threat of gusty to damaging winds with this line.
QPF is a bit lower this run due to a more progressive movement of the
line tonight into early Tuesday morning. Amounts of 0.75-1.25 inches
will be common, but still not excluding the possibility of amounts
in the 1.5-2.0 inch range in a short period of time. Thus, will keep
the FFA out tonight.
.SHORT TERM...(Tuesday through Wednesday)
Issued at 111 PM CDT Mon Jun 21 2021
With the passage of the cold front and only lingering light rain
showers early Tuesday morning, have opted to expire the Flash Flood
Watch at 15Z. A clearing sky will take place through the late morning
into early afternoon, with dew points falling into the 50s to lower
60s. With added sunshine, temperatures may still reach 80 in a few
areas, but some will stay in the 70s, especially the higher
elevations. Morning lows Wednesday will dip into the middle to upper
50s. A weak shortwave will pass by mostly unnoticed Wednesday with a
rather dry atmosphere. High temperatures should reach the lower to
middle 80s.
.LONG TERM...(Wednesday night through Sunday)
Issued at 111 PM CDT Mon Jun 21 2021
An upper ridge builds east from the southwest U.S. across the western
Gulf states through the weekend. However, MCSs will charge east
across the northern Plains into the eastern corn belt, and tend to
"spillover" the ridge southeast into the OH valley. The models appear
to be less favoring this activity dropping southeast into the TN
valley. But, more diurnally driven thunderstorms may still occur
on Friday into Saturday. On Sunday, a slow moving and weakening
frontal boundary will lie from KY into northwest TN. As a result,
MCS/clusters of thunderstorms will likely spread closer to our
forecast area, especially northwest AL into southern TN. The front
may stall out just to our northwest, but will still be in close
enough proximity for greater chances of showers and thunderstorms on
Sunday (and beyond).

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1145 AM CDT Mon Jun 21 2021
Scattered SHRA and TSRA will occur through 00Z during afternoon
heating. Conditions may drop briefly to IFR in +RA with gusty winds
also possible in and near TS. A cold front will drop southeast this
evening producing a band of widespread +TSRA, again lowering
conditions to IFR at times. By 03-04Z, most of this activity will
shift southeast, with lingering SHRA possible. Ceilings will lower
into the 015-020agl range (MVFR) until 07-08Z when the cold front
will shift winds to the northwest. Lower ceilings will persist
however, even down to 005agl (LIFR). Improvement to MVFR with
ceilings ~020agl is expected by 13-14Z.
