Area Forecast Discussion
National Weather Service Huntsville AL
613 AM CDT Sat Oct 1 2016

For 12Z TAFs.


(Issued 158 AM CDT Sat Oct 1 2016)
The upper low over srn IN is slowly starting to drift N/NE. Attm the
cloud cover associated with the upper low is not as widespread over
the TN valley as last night. Based on stlt trends most of the cloud
cover should be north of TN river for the rest of tonight and today.
Otherwise will go ahead and keep patchy fog wording for this mrng
based on current temp/dewpt depression.

The upper low is progged to continue to move NE thru the weekend as
an upper ridge builds eastward from the midwest. This scenario will
continue the dry conditions over the CWA as well as a slight warming
trend. Today highs will mainly be in the upper 70s but by Sunday and
into next week aftn highs will be in the low/mid 80s with mrng lows
in the upper 50s to lower 60s.

Attm the only chc of shra/tsra will be on Thursday as an upper trof
and sfc cdfnt approaches the TN valley from the west and hurricane
Matthew moves somewhere along the east coast. GFS is still the drier
model than the ECMWF with the chc pcpn on Thursday. Any way you cut
it, the chc of pcpn on Thursday looks fairly slim since the TN
valley should be on the west/dry side of Matthew.



For 12Z TAFs: The chance for 3-4SM visibilities is low at this point
but will continue a 5SM TEMPO group at KMSL through 13z. SCT-BKN040
CIGS are expected through the morning with clouds scattering out
this afternoon as high level clouds move in. Winds will be less than
10 knots today and light and variable again overnight.
