DISCUSSION...
The threat for freezing temperatures and an extended period of dry
weather expected across the Mid-South.

West to Northwest flow aloft will keep continental airmasses and
high pressure around the Mid-South into early next week. Tonight
high pressure and light winds will cause temperatures to drop back
into the 30s across most areas.  Areas of frost are likely across
portions of West Tennessee.  Patchy frost could also extend south
into north Mississippi.  Will issue a Frost Advisory for portions of
west Tennessee or about the northeast quarter of a service area.

After a mild day Saturday a strong shortwave will drop southeast in
the flow and push a cold front across the area Sunday morning. As
high pressure builds quickly into the region freezing temperatures
and frosty conditions seem likely for much of the forecast area by
Monday morning, with the Mississippi Delta region remaining the
warmest. This event is over 48 hours from occurring so will hold
off on any Freeze Watches, however we will highlight in social
media.

As next week progresses another weak shortwave will approach the
region and eventually close off over the southeast US.  A pressure
ridge will remain dominate at the surface, thus with lower heights
aloft, expect a period of mild days and chilly nights to finish
off the week. No rainfall is expected through the week, perhaps
extending into next weekend.

.AVIATION...
/00z TAFs/

Light northeast winds will persist overnight, becoming
southeasterly after sunrise. Winds will eventually veer more
southerly, increasing to 5-8 kts. VFR conditions will prevail with
only a few high clouds throughout the day tomorrow. Some very
patchy valley fog will be possible late across west TN, but
confidence is low that this will affect the forecast terminals.
