For 12Z TAFs.
(Issued 321 AM CDT TUE MAY 24 2016)
Another predom quiet night ongoing across the cntrl TN Valley this
early Tue morning, even with some mid/high clouds passing ewd over
parts of the area. Upper ridge pattern is beginning to translate
slightly to the e over the Lower MS Valley region, which should aid
in a gradual warming trend starting Today, as afternoon highs climb
into the mid/upper 80s for most locations. High pressure at the sfc
is also gradually making its way ewd toward the mid/srn Atlantic
Basin, with a return flow becoming well entrenched across the
region. The upper ridge pattern will continue to translate ewd
through the middle of the week, with afternoon temps warming mainly
into the upper 80s to near 90F. Overnight temps after Wed also look
to warm a little bit, with early morning lows more in the mid 60s for
the latter half of the work week.
Rain chances later this week continue to look rather bleak, as the
upper ridge pattern becomes better established over the SE states.
Latest model suites are continuing to deflect most of the available
energy/moisture to the w/n of the local area, through at least
Thu/Thu night now. There may be just enough of a shift ewd/weakening
of the upper ridge to allow some of this energy to spread into parts
of the area starting Fri, although rain chances will be rather low.
With the sfc high displaced well to the e, this will at least help
with some continued moisture flow into the area from the s. A
somewhat active flow pattern out of the wsw continues into the
weekend, although how many of these weak upper disturbances make it
into the area remains uncertain. The latter half of the model
guidance may be hinting at the flow pattern becoming a bit more
active by the start of the new work week, as a few more upper waves
attempt to move across the region.
Overall temps look to remain seasonably warm going into the weekend
period, with most of the region remaining under the influence of the
Subtropical ridge. Afternoon highs mainly in the mid/upper 80s look
to prevail while overnight lows predom hold in the mid 60s.
For 12Z TAFs:
VFR weather should prevail this TAF period. Light/variable winds
after daybreak will become SW in the 5-10 kt range by the late
morning. Slightly higher levels of lower level moisture...coupled
with strong daytime heating...will result in a few to scattered
cumulus forming under few to scattered higher cirrus. Winds once
again will become light/varible shortly after sunset this evening.
