Morning update.

.DISCUSSION...
This morning was very similar to yesterday with overnight lows
ranging in the low to upper 60s with mostly clear skies and high
pressure still in control.

Yesterday, another high temperature record was broken at KHSV when
they reached 97 degrees. The old record was 96 degrees set back in
1961. With the upper-level ridge in place for one more day, records
are in jeopardy again! At KMSL the record high temp for today is 97
set in 1933 and at KHSV it is 100 that was set in 1931. Current temps
are already in the low to mid 80s across the TN Valley so stay tuned
to see if there will be a hat trick of records broken this week!

The upper-level low stationed over the panhandle of FL will pull in
additional moisture and cloud cover this afternoon but the forecast
will remain dry. Adjusted a few temps and the dewpoints heading into
this afternoon. Otherwise, no major changes were made to the
forecast package.

.PREV DISCUSSION...
(Issued 223 AM CDT Sun Sep 25 2016)
This morning`s wx map shows a cdfnt extending from an upper low over
the nrn plains to nwrn TX, while an upper ridge stretched from the
Great Lakes thru the sern US. There was also a weak upper low over
nrn FL which was bringing an increase in mid/high level moisture over
much of central and srn AL, as well as GA.

Today should be pretty much like Saturday, with hot temps and dry
conditions. The TN valley will have aftn highs once again in the mid
to perhaps the upper 90s. There may also be a few record highs set
again this aftn. The record high for HSV is 100 in 1931 and the
record high for MSL was 97 in 1933.

About the only significant weather going on for the next 7 day will
be a chc of shra/tsra on Monday as a cdfnt moves across the area.
Attm the timing of the cdfnt looks to be over NW AL arnd 12z, the HSV
area by 17z and out of the CWA by 22z. There will be enough
instabilities for some sct tsra mainly during the aftn, but the
threat for svr wx looks low attm. Also as the cdfnt moves across the
cwa on Monday, not expecting much rainfall with it, maybe up to a
quarter of an inch. The chc of shra/tsra will taper off during the
early evening from west to east. All pcpn should be out of nern AL by
midnight, if not a little sooner.

The rest of the fcst, Tuesday thru Saturday, should be more fall
like with aftn highs arnd 80 and mrng lows in the lower 50s with a
few upper 40s possible in some locations. The dry weather will also
continue thru this period with dewpoints mainly arnd 50 degrees. This
dry wx pattern will not help the current drought situation across
much of the TN valley.
