Area Forecast Discussion
National Weather Service Huntsville AL
255 PM CDT Fri Oct 21 2016

.NEAR TERM...(Tonight)
Issued at 250 PM CDT Fri Oct 21 2016

The upper trough axis was moving east of the region this afternoon
with most of the lower clouds shifting east-northeast of the forecast
area. Cold advection was continuing to move southeast into the region
with temps this afternoon 15-20 degrees cooler than Thursday. Skies
should clear across most of the forecast area except for portions of
northeast Alabama by 00z Tonight. Clear skies are then expected area
wide for the majority of tonight and have slightly lowered overnight
low temps in north central Alabama.

.SHORT TERM...(Saturday through Sunday)
Issued at 250 PM CDT Fri Oct 21 2016

The large area of high pressure will shift slowly east-southeast
through Sunday with dry and cooler than normal temps expected. Have
made some slight adjustment to temps through the forecast period to
account for diurnal changes under this pattern.

.LONG TERM...(Monday through Thursday)
Issued at 218 AM CDT Fri Oct 21 2016

Dry weather will continue into the first half of the work
week as the ridge lingers across the region. Combined with mostly
clear skies, temperatures will remain in the mid/upper 70s and
overnight lows in the upper 40s will warm in the low/mid 50s. A
short wave on Wed/Thurs will dampen the ridge, increase cloud cover
and provide a slight chance of rain to mainly our southern middle
TN counties Wed night. The ECMWF finally looks more like the GFS with
this solution, so left in the precip for this timeframe. This is the
only mention of precip in the extended forecast at this time.


.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1220 PM CDT Fri Oct 21 2016

VFR conditions are expected through the forecast period for HSV and
MSL. Expect a scattered 3kft cloud deck to become SKC by 00Z at both
TAF sites and winds will begin to lessen to around 8 knots out of
the northwest during the same time period. Generally lighter winds
out of the northwest 5-7 knots or less are expected through the rest
of the TAF forecast period.
