Area Forecast Discussion
National Weather Service Morristown TN
1241 PM EST Sun Feb 26 2023
...New AVIATION...
.UPDATE...
Issued at 1035 AM EST Sun Feb 26 2023
Forecast looks to be in fairly good shape this morning. Only
notable changes made were minor adjustments to PoP grids to
follow recent radar trends(a tad increase from previous forecast).
Weak moisture convergence at the surface associated with a west-
east oriented stationary boundary to our south has allowed for
some areas of light showers traversing across the area, generally
along and just south of the I-40 corridor. Surface observations
show that fog conditions are gradually improving as well.
Otherwise, a cloudy day is on tap for the region ahead of Monday's
approaching weather system.
&&
.SHORT TERM...
(Today and tonight)
Issued at 248 AM EST Sun Feb 26 2023
Key Messages:
1. Patchy fog in the morning with low clouds all day. Patchy dense
fog is possible in the Cumberland Plateau counties this morning.
2. Isolated light showers in the afternoon.
Discussion:
Today is going to be a rather mild and dreary February day. Lots of
low clouds around, with low level moisture trapped beneath an
inversion all day. Deterministic modeling shows some isentropic lift
in the afternoon, and CAM guidance has been showing scattered
showers. Best chance for rain will be in the central Tennessee
valley in the afternoon. QPF is extremely light, so no impacts are
expected. Sunday night there may be an isolated shower as Monday's
system lifts our current weather up and out, but most of the area
will remain dry.
&&
.LONG TERM...
(Monday through Saturday)
Issued at 248 AM EST Sun Feb 26 2023
Key Messages:
1. Active pattern continues with multiple systems impacting the
region throughout the week. Lower confidence exists in the late
week system.
2. For Monday, gusty winds are expected area wide as a line of
showers moves through the region. Low probability of isolated
damaging winds from the showers/potential isolated tstorms.
Discussion:
Sunday night into Monday strong upper troughing will result in
surface low pressure tracking from the central CONUS towards the
Great Lakes Region. An associated cold front will advance eastward
and bring scattered to numerous showers. Severe threats seem
marginal at best for multiple reasons. Firstly, the majority of
favorable upper level forcing remains displaced to our north.
Secondly, model derived soundings from the NAM(Which is often times
the most bullish with instability) suggest measly MUCAPE of 200 J/kg
or less along with rather unimpressive lapse rates in the 5 C/km
range. Nonetheless, heaviest showers could help translate stronger
winds aloft to the surface and result in isolated damaging gusts.
Minimal instability and forcing will keep thunder rather sparse, if
any at all, as well.
In general, gusty winds will be the main area wide impact Monday. A
strong low-level jet of 50-55kts primarily out of the southwest will
result locally stronger gusts up to 50mph in the higher elevations
of the East Tennessee mountains. Gusts up to 40mph will be possible
elsewhere.
After the front passes through, high pressure builds in as dry
conditions are anticipated through Tuesday and much of Wednesday. By
Wednesday night, isentropic lift increases as a southwest-northwest
oriented frontal boundary drapes across the region bringing a return
of widespread precipitation chances. An additional system will
follow Thursday night into Friday but less confidence exists due to
wide model solutions on the track of the surface low. Overall, the
wet pattern is likely to continue during the late week. Trends in
QPF will be monitored for potential flooding issues. Temperatures
will generally be near to above normal throughout the week.

.AVIATION...
(18Z TAFS)
Issued at 1232 PM EST Sun Feb 26 2023
Poor flight conditions will continue through the 18Z TAF period
due to the presence of low clouds. This afternoon, low level
moisture has been stubbornly persistent across the northeast area
where winds remain calm or very light. MVFR or lower cigs are
expected to persist through the the TAF cycle. The possibility of
fog overnight still exist but remains uncertain, especially
regarding the duration as winds will be on the increase tomorrow
morning and help mix the boundary layer. Rain chances increase at
the tail end of the period with strong gusty winds expected
tomorrow afternoon.
