.SYNOPSIS...
A ridge of surface high pressure will extend from central IN into
west central OH this morning. The ridge will linger over the
northern 2/3 of Ohio through early Sunday and then shift southward.
Dry weather is expected through at least mid week.
&&
.NEAR TERM /UNTIL 10 AM FRIDAY MORNING/...
A rogue shower crossing se through Hocking county is the only
expected precip and will be through in the next hour or so. Clearing
sky cover will occur in the east, with scattering 5-8kft clouds over
n and w of Dayton. Clearing in the mid sections of the CWA and the
southwest has shown some sites quickly drop vsbys to under a mile,
and this is expected to expand for much of the remainder of the CWA
before too long. A dense fog advisory is in effect until 10:00 for
this area.
Morning lows will range from the mid 50s over IN and west central OH to
the upper 50s elsewhere.
&&
.SHORT TERM /10 AM FRIDAY MORNING THROUGH SATURDAY/...
Quiet weather will be in place for the short term with just some cu
expected on Friday after the fog dissipates. Highs should fall
between 75-80 degrees with overnight lows in the mid 50s. More fog is
expected for early Saturday morning as light winds and clear skies
create a favorable radiational cooling environment.
Saturday should be just as pleasant with highs near 80 and partly
cloudy skies.
&&
.LONG TERM /SATURDAY NIGHT 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.
