A frontal boundary will briefly stall out near the ohio river by
Monday morning. The front will lift back north as a warm front on
memorial day, keeping a chance of showers and thunderstorms in
the forecast. Warm and humid conditions and unsettled weather
will be the rule into the upcoming week with a chance of
thunderstorms each day.

Near term until 6 am Monday morning
A diffuse frontal boundary will settle near or south of the ohio
river by Monday morning. The loss of instability, forcing, and
upper support, should allow any lingering shower storm across
our southern cwfa to dissipate by early morning.

The big question later tonight will be the formation of stratus
and or fog. The signal is there from various models. However,
confidence in coverage and severity (i.E. Outside river valleys)
of fog is still low at this time. Have placed patchy fog in the
forecast for mainly locations across the southern half of the

Overnight low temperatures to range from the upper 50s far north
to the lower 60s elsewhere.

Short term 6 am Monday morning through Monday night
Another mid level shortwave to track through the ohio valley
with the front lifting back north as a warm front Monday
afternoon. Moderate instability develops late in the day across
the west as the warm front begins to pivot north. Severe storms
will again be possible in this region. Mondays highs to range
from the upper 70s north to mid 80s south.

Mid level ridge builds into the region Monday night with the
front pushing north of the region into the great lakes. Storm
chances will diminish across the south but will keep a slight
chance across the far north. Expect mild lows Monday night in
the mid and upper 60s.

Long term Tuesday through Sunday
An active weather pattern will continue through the coming

The ohio valley will remain on the northern periphery of a mid-
level ridge through Thursday, with occasional chances for storms
expected as disturbances move eastward through the flow. As
this occurs, a surface frontal boundary is expected to remain
somewhere in the area, though generally favored to be just north
of the iln cwa, keeping the region within an area of warm and
moist conditions. As it appears right now, this boundary should
almost certainly be north of the area on Tuesday, leading to the
cwa being largely warm sectored and capped, and unlikely to be
a source of convective development. Nonetheless, there are some
indications that convection developing closer to the front may
propagate southward into the forecast area during the
afternoon evening, warranting some 20-30 pops north of
interstate 70. Tuesday should also be the warmest day of the
extended period, with highs in the mid 80s to lower 90s. As the
front oscillates slightly southward on Wednesday, and a
shortwave approaches from the west, temperatures should moderate
slightly -- but chances for storms will also increase.

A more pronounced shortwave is expected to move into the area
on Thursday, along with a further southward progression of the
surface boundary. This will lead to what appears to be the
greatest chance for precipitation during peak diurnal timing.

Beyond Thursday, there are timing differences in the models
regarding the progression of a secondary trough moving across
the great lakes -- the 00z ecmwf, for example, is a little more
amplified and slower with its eastward motion. Thus, there is
much less certainty with the precipitation forecast for Friday
and beyond. This is especially true heading into the weekend,
when flow will set up in more of a pseudo-zonal orientation,
with quicker shortwaves that are very hard to time out.

Temperatures from Thursday through the weekend should be
slightly cooler than earlier in the week, but generally still
near to slightly above normal.

Aviation 03z Monday through Friday
Scattered showers and thunderstorms will continue to wane this
evening as instability decreases and embedded disturbance moves
away to the east from our area. Thereafter, a weak cold front
will sag slowly south toward the ohio river where it will
briefly stall out toward 12z. With recent rainfall and light
winds, there will be the potential for stratus and or fog to
develop across the much of the terminals. Kcmh klck may be on
the edge of this potential and have the best conditions here,
while ifr lifr and even vlifr may develop (especially river
valley fog) at other locations.

On Monday, stratus and or fog will lift with diurnal heating
into a sct-bkn cumulus deck. Old front boundary is forecast to
lift northeast as a warm front during the day. Increasing
instability and perhaps an embedded disturbance in the zonal
flow aloft will bring a chance of showers and thunderstorms
during the afternoon and evening. Have only placed a vcsh at the
terminals at this time given low confidence low coverage. Winds
will veer to the south once the warm front passes by.

Outlook... Thunderstorms possible Monday night, then again
Wednesday and Thursday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
