Upper level system Monday night. Cold front Tuesday night. High
pressure through Friday night.
Near term through tonight
As of 311 am Monday...
upper level ridge that brought the dry conditions this past weekend
in our area continues to move further eastward into eastern canada.
Meanwhile, a shortwave trough is moving nne across the mid
mississippi valley, with widespread light to moderate showers
streaming northward in the central ohio valley. As the upper ridge
continues to slide further east and the shortwave trough pushes into
the ohio valley this afternoon, moisture advection and broad ascent
will be increasing across the region. Currently, the western edge of
our area remains on the edge of a sharp moisture gradient, where
pwats are greater than 2 inches in central ky while values are
less than an inch in the tri-state region. However, as the
aforementioned trough continues to approach later today, pwats
are progged to increase to around 1.50-1.75 inches as southerly
flow increases. Thus, pops will generally increase from west to
east through the day, but the shortwave trough will be lifting
more northward as opposed to eastward, so only expecting a slow
eastward progression in the precipitation activity towards our
area. In addition, added slight pops for far northeastern areas
of the CWA late afternoon and evening as low level ese flow on
the southern edge of a surface high in eastern canada may allow
a few light showers to develop along the eastern slopes in
advance of the approaching trough.
Despite the increase in moisture later this afternoon and evening as
pwats increase and the column saturates, only light to occasional
periods of moderate rain is expected to develop. This will be due to
the better forcing remaining north of the area as an upper level low
embedded in a deepening trough in manitoba digs southward and pulls
the lead shortwave trough northward. However, there will certainly
be enough lift to maintain pops through the end of the near
term period. Another thing to mention is that convective
chances today appear to be extremely low as instability is
expected to be nearly non-existent, which will keep rainfall
rates in check. Given the thickening cloud cover and increasing
rain chances expected today, temperatures will be around 5
degrees below normal, as most areas struggle to reach 80f.
Short term Tuesday through Wednesday
As of 245 am Monday...
an upper level wave exiting to the northeast will lead to
decreasing pops from 12z Tuesday going forward through the day,
with weaker disturbances in the flow aloft traversing the area
preventing elimination of the pops. This is all ahead of the
main cold front that will work its way into the ohio counties
after 00z Wednesday, with passage through the mountains of the
cwa expected by 15z Wednesday. The closed upper low surface low
will track northeastward towards hudson bay, and with some
weakening of the system overall, the better dynamics will exist
well to the north of our area, minimizing the severe potential.
The lower level 850mb flow is likely to be less than 25kts with
the front and instability is lacking due to mid level warming,
and agree with the SPC diagnosis of general thunder for the
Long term Wednesday night through Sunday

getting back into a drier pattern in the wake of the cold front
and high pressure building over the appalachians through Friday.
Flowing gradually transitioning from broad cyclonic to zonal
likely will not produce anything given the lack of column
moisture until the next cold front drops in, steered by the
500mb flow that will be much more active over canada than at our|
latitude. The timing of any frontogenetic forcing with this
boundary has not been consistent in the long term models, but
should see some shower activity later in the weekend in our

surface high pressure in eastern canada will maintain fairly
quiet conditions through the remainder of the night. However, low
level ese flow on the southern end of this feature will maintain
low stratus along the eastern slopes, though this activity
shouldn't have any impact at ekn. Meanwhile, mid upper level
clouds are increasing from the southwest ahead of a disturbance
in the mid mississippi valley. This increase in cloud cover
through Monday morning should help preclude fog development
tonight across the region soVFR conditions should prevail.
By Monday morning, areas of light to moderate showers will move
across the ohio valley as the aforementioned disturbance lifts
to the nne. As the upper disturbance and associated showers
continue to approach the region from west to east through the
day, CIGS will gradually lower as the afternoon progresses.
MVFR CIGS are expected to approach the area as the atmosphere
continues to moisten this evening. Vsby restrictions will also
be possible as precipitation continues to increase in coverage.
In addition, periods of ifr conditions can't be ruled out during
periods of heaviest showers.
On and off showers will continue through the end of the taf
period as the upper disturbance swings through the region,
maintain MVFR and possibly ifr conditions.
Forecast confidence and alternate scenarios through 06z Tuesday...
forecast confidence: high through majority of the period.
Alternate scenarios: flight restrictions arising late Monday
afternoon as rain moves in from the west.
Experimental table of flight category objectively shows consistency
of WFO forecast to available model information:
h = high: TAF consistent with all models or all but one model.
M = medium: TAF has varying level of consistency with models.
L = low: TAF inconsistent with all models or all but one model.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
