Update
For 00z tafs.

Near term (tonight)
issued at 220 pm cst Wed jan 17 2018
skies have cleared across the region this afternoon as the surface
ridge continues to build southward toward the tennessee valley. As of
early afternoon temperatures have "warmed" into the upper teens to
lower 20s in most locations with wind chills generally in the single
digits. Looking out the window and utilizing the goes-16 rgb products
reveals a significant decrease in the snow cover across the tn
valley this afternoon with the remaining snow generally west and
north of a line from winchester to athens to red bay. For tonight,
expect another cold night with readings approaching the single digits
in the colder valley locations and where snow lingers a bit.

Short term (Thursday through Friday)
issued at 220 pm cst Wed jan 17 2018
some good news for Thursday Friday as we begin to see a slow
"warming" trend. The aforementioned surface ridge will begin to
weaken and drift southeast with time. We once again reach the
freezing mark by midday Thursday and by that time any remnant
snow ice should be history. One more rather cold night is in store
Thursday night with temperatures well down in the teens areawide.

Have hedged toward the lower end of guidance as the last night of a
cold outbreak tends to be lower colder than guidance predicts.

Weak southerly flow commences on Friday in advance of a developing
weak upper low in the vicinity of the northwest gulf. Although we
won't reach normal highs on Friday, temperatures in the mid to upper
40s will seem almost springlike compared to earlier in the week.

Some guidance has trended a bit more aggressive with the low
developing in the gulf and we will need to monitor its progress and
associated moisture return as we move toward the extended period.

Long term (Friday night through Tuesday)
issued at 220 pm cst Wed jan 17 2018
if you are looking to catch a break from the cold stretch we have
been stuck in, the extended forecast has it for you. We could even
exceed normal temps, especially on Sunday. Normal temps for this
time frame is a high of 51 and low of 31 degrees.

Sfc high pressure that is currently sprawled across the southeast
will shift eastward this weekend, returning southerly flow and
moisture to the region. A shortwave will swing just to our south
Saturday. Soundings show an increase in shallow moisture with sfc
temps remaining just above freezing. The ECMWF brings it through
much later, so continued to keep precip out at this time. Saturday's
highs warm up and return to normal, reaching the lower 50s across
the tn valley! Overnight lows will be in the upper 30s lower 40s. A
strong trough will sweep across the country this weekend and
strengthen as it lifts into the great lakes region by Monday. Wwa
ramps up ahead of this system helping Sunday be the warmest day of
the forecast period. Sunday's highs will be around 60 degrees with
lows in the mid 40s! As we head into the new work week, a sfc low
will lift up into the great lakes region. Showers and a few
thunderstorms will develop along the trailing cold front and push
into the forecast area Sunday night Monday morning. The front will
move through quickly with precip exiting the area late Monday night.

Models differ in timing with the GFS still trending faster than the
ecmwf, but both increase pwats over an inch Monday afternoon and
keep instability limited, therefore not expecting severe weather at
this time. Tuesday will see mostly sunny skies with near normal
temperatures.

Aviation (for the 00z tafs through 00z Thursday evening)
issued at 532 pm cst Wed jan 17 2018
vfr conditions will be the predominant flight category at each
terminal through the period. Winds will drop off after 01-02z as the
nocturnal boundary layer sets up under a clear sky. Some light fog
may develop late tonight into early Thursday morning at kmsl.

Otherwise, clear conditions and light winds will continue into the
day on Thursday, gradually backing to the west to wsw late in the
day.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
