Area Forecast Discussion

.PREV DISCUSSION... /Issued 237 PM EST Mon Jan 23 2017/

SHORT TERM /Tonight through Tuesday Night/...
Models in good agreement with the system continuing to exit the CWA.
Skies will clear from the west tonight with mostly sunny skies for
Tuesday as the H5 ridge builds over the region. Winds will remain
strong out of the northwest with speeds diminishing tonight. Will
maintain the Wind Advisory until 7 PM. Some areas in the higher
elevations could remain strong and gusty a little further into the
evening...but by midnight even those will have diminished. MOS
Guidance temps look good and have gone with a MAV/MET mix.

LONG TERM /Wednesday through Monday/...
Extended forecast continues to look on track with the latest model
solutions. A few models are beginning to indicate an upper level
disturbance dropping down over the Tennessee Valley late this
weekend into Monday. For now there is still enough uncertainty
with the position of the best moisture and how far south the
disturbance will move, and so have continued with a dry forecast
for the weekend and into early next week. Previous discussion
follows...

/Issued 306 AM EST Mon Jan 23 2017/
Medium range models in relatively good agreement, at least
concerning the large scale pattern, through the extended forecast
period. With this in mind, and considering the limited time
available to delve deeper into the extended period due to ongoing
weather concerns, I have generally loaded a model blend through
the extended period and made minimal tweaks. Mid-week system
brings rain back into the forecast by Wednesday afternoon, with
best chances along and ahead of the frontal boundary sweeping
through Wednesday night into Thursday morning. Models are keeping
any wrap-around moisture north of the forecast area Thursday night
and this period is now dry in our forecast grids as well. The
remainder of the period still looks dry and seasonably cool.
