A low pressure system will push slowly south across the region
through Monday, resulting in a continued chance for showers and
a few thunderstorms. The threat for showers and thunderstorms
will then persist through mid week as an upper level trough
moves across the region. Cooler than normal temperatures will
moderate to more normal readings through the week.
Near term until 6 am Monday morning
Elongated mid upper level low from the great lakes through the
tn vly. Associated sfc low centered over NE ky. With loss of
heating only observing scattered showers and a few embedded
thunderstorms over iln S southeast counties, which corresponds
with inverted sfc trof and favorable low level convergence.
Expect pcpn coverage to continue to diminish and with chance
pops mainly over the southeast. With abundant low level moisture
expect low clouds to fill in as was observed last night. Lows
tonight to range from near 60 northwest to 65 southeast.
Short term 6 am Monday morning through Monday night
The upper level system will continue to weaken Monday into
Monday night as it shifts south across the region and becomes
more elongated. This will allow for the surface low to also
push off to the south and become more diffuse Monday into
Monday night, with more of an inverted trough nosing up into our
area. While pcpn coverage should be less than today, will go
ahead and allow for some increasing chance pops and a mention of
thunder through the day on Monday as we start to get some
diurnal enhancement. Then once again as we lose this diurnal
component, will taper pcpn back through Monday night.
Temperatures on Monday will again be below seasonal normals with
highs mainly in the upper 70s to near 80.
Long term Tuesday through Sunday
A long wave upper trough will dictate weather conditions
through the period.
On Tuesday, when the upper trough will extend all the way from the
great lakes to the gulf of mexico, thunderstorms are likely to
develop and effect mainly eastern locations under the upward motion
side of the trough, enhanced by a broad and weak surface low. Severe
weather chances will be limited by weak wind flow, though heavy rain
will be possible in an airmass containing 1.8 inches pwat and slow
moving storm cells. Wednesday may see a repeat of this, though storm
strength may be further limited by decreased forcing and instability|
as the upper trough fills in.
A more zonal flow aloft should be evident on Thursday as the upper
trough broadens, producing surface high pressure and mainly dry
weather. Similar conditions may persist through Friday and Saturday,
before thunderstorm chances return Sunday ahead of surface low
pressure developing in front of a reinforcing shot of upper level
Temperatures will be a bit below normal for the most part, with
highs reaching the low to mid 80s most days. The exception may be on
Wednesday when readings could be nudged up to the mid and upper 80s
due to increased insolation under the surface high.
Aviation 03z Monday through Friday
Quasi-stationary surface low pressure was centered over south
central ohio early this evening. Scattered showers and a few
thunderstorms were rotating around this low. Western ohio is in
a pcpn void area with the best chance of a shower looks to be
across kiln kcmh klck this evening. Thunder chances appear low,
so have only a mention of vcsh. Pcpn coverage will gradually
decrease after sunset, but an isolated shower can not be ruled
Cigs are currentlyVFR but expect a lowering to MVFR cigs
late this evening. Ifr CIGS are not our of the question but
latest guidance is not as pessimistic so have kept CIGS in the
These MVFR CIGS will likely persist through much of Monday morning
hours before gradually improving toVFR by afternoon. Showers
and a few thunderstorms will again increase in coverage Monday
afternoon under the influence of stacked sfc upper low. Have
vcsh at kcvg kiln kluk and kday with vcts at kcmh and klck
where better chances for pcpn will exist.
Outlook... Thunderstorms possible at times, mainly during the
afternoon and evening, Tuesday through Wednesday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com 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.
