.SYNOPSIS...
An upper level disturbance continues to push east tonight, allowing
lingering rain showers to taper off. Expect mostly dry conditions
Friday through the middle of next week, with only minimal chances for
rain.
&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
Weak subsidence behind the cold front that has crossed through the
region will allow for clearing skies this evening into the early
overnight hours. This, combined with calm winds and antecedent wet
soils, will allow for good radiational cooling. As the ground cools,
a decent inversion will set up, trapping moisture below it and
promoting fog development, likely beginning around midnight and
persisting through sunrise for most spots. Some locally dense fog
might be possible. For now, have continued mention in HWO and will
add to social media tonight to highlight this threat. Remember, if
driving in foggy conditions, do not use your high beam headlights, go
slow, and leave extra stopping distance.
Previous discussion--> Scattered showers will gradually taper off
overnight as an upper level disturbance pushes to the east. As the
showers taper off and cloud cover starts to decrease expect fog to
develop across the region. Highs in the 70s today will give way to
50s for lows tonight.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
Quiet weather will be in place for the short term with just some cu
around during the day on Friday. High temperatures on Friday are
expected to be in the middle 70s to around 80 degrees and lows
temperatures Friday night expected to drop into the 50s.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
As the main upper level trough shifts off to our east, a weak cutoff
low will develop in its wake across the Tennessee Valley this
weekend. This could lead to a few showers across our far southeast,
but with high pressure still in place at the surface, expect the
majority of our area to remain dry. Temperatures will be a few degree
above normal both Saturday and Sunday, with daytime highs in the
upper 70s to lower 80s and overnight lows in the mid to upper 50s.
The cutoff low will drift slowly east through the first part of next
week and begin to interact with some of the tropical energy
affecting the southeast US. There remains a fair amount of model
discrepancy on exactly how this will all play out. However, with
subsidence on the northwest side of this, expect our area to
generally remain dry. Temperatures will trend more seasonable
through mid week with highs mostly in the mid 70s by Wednesday and
Thursday.
&&
.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
Some lingering showers continue to move through the region this
evening, tapering off during the overnight. Skies will clear out for
the first half of the night and winds go nearly calm; this, combined
with recent wet soils, will allow for fog development. Have dropped
all sites VSBYs down during the overnight hours to account for this.
Concurrent with foggy conditions, a low level inversion develops,
which will trap a low stratus deck across much of the region during
the early morning. Have dropped CIGs to MVFR.
Fog/ low CIGs clear shortly after sunrise on Thursday and scattered
cu remain with light winds out of the north.
OUTLOOK...No significant weather is expected at this time.
