Stinkin` clouds. They stung me on highs yesterday by a degree or
two, but we still crept to 80 in a couple of spots and tied the
record at BNA. With this westerly
flow aloft expected to continue
for one more day, we`re going to be close to record highs again
today. On top of that, it does look like it will be breezier today
than yesterday. This should assist in mixing some dry air to the
surface and aid in warming us another degree or two by the
afternoon. Today`s records are 83 at BNA (2005) and 77 at CSV set
just last year and both will be in jeopardy. As far as any fire
weather concerns,
RH values could dip into the upper 30s in a few
spots this afternoon with any mixing that may occur, but we should
remain above marginal fire criteria.

Much needed
rainfall is on the way, Middle TN. Still
progged to
arrive on Thursday and spread across the mid-state Thursday night
and Friday, this slow-moving frontal boundary should provide us with
an average of about 1/2 inch between the two days. Some will see
less, some a little more, with a pretty decent signal that those in
the more extreme
drought areas could see those higher values. In
the end, this is not going to be a
drought buster, but any little
bit will help right now. Behind tomorrow`s frontal passage,
temperatures will fall back to much more
normal readings for this
time of the year.
To illustrate the model struggles right now, the Euro and
GFS have
seemingly swapped solutions from last night as to any of us getting
weekend rain. Even if it happens, it isn`t going to be much.
Likely
only a couple hundreths anywhere.
Extended guidance shows yet another lengthy stretch of dry weather
starting Monday. While temperatures will remain near
normal
throughout the week, it could be Friday of next week before
PoPs
start to creep back into the forecast.
