As surface low pressure moves into the great lakes, increasing
southerly flow will bring moisture into the ohio valley today.
Showers and thunderstorms chances will increase today ahead of a
cold front which moves across the area tonight. Drier and cooler
conditions are expected on Friday, as high pressure moves into
Near term until 6 pm this evening
An extensive CU field has developed across the forecast area and
expect thunderstorm development over the next hour or two. Hi
res models are also supportive of this. In addition there is a
broken line of storms in indiana and expect these storms to move
into the region as well this afternoon. The main threat with
these storms this afternoon will be damaging winds, however an
isolated tornado or large hail cannot be ruled out. In addition
heavy rain will be possible with the storms as well.
Temperatures have already climbed into the 80s and are expected
to peak in the middle to upper 80s today. Went close to guidance
for high temperatures for today. Winds have also already
started to pick up with wind gusts around 20 to 25 mph expected
through the afternoon and into the evening hours.
Short term 6 pm this evening through 6 pm Friday
Ongoing storms this evening along pre-frontal trof with moderate
instability over the area. Thunderstorms will propagate east
across iln S area with a few strong severe storms possible this
evening. Actual cold front does not move through until late
tonight, so a few showers thunderstorms could linger until the
passage. Low temperatures to range from the upper 60s northwest
to the lower 70s southeast.
Mid level S W to pivot from the northern great lakes into
southern canada with westerly flow across the ohio valley
Friday. In the post frontal environment surface high pressure to
build east into the region late in the day. This will allow for
decreasing clouds. Temperatures will be cooler and closer to
normal, with highs on Friday in the lower and middle 80s,
Long term Friday night through Wednesday
Friday night will have dry weather under a ridge of high pressure.
A rather potent short wave traveling across the great lakes on
Saturday may trigger a few thunderstorms, mainly in northern|
locations. An extensive area of surface high pressure under a
westerly flow aloft will become the dominant weather pattern for
Sunday and Monday. Sunday is expected to be dry, while isolated
thunderstorms may occur in southern counties Monday due to
increasing humidity instability in the anticyclonic circulation
around the surface high.
For Tuesday, convergence and lift associated with a cold front will
produce a good chance for thunderstorms. Chances diminish Wednesday
in drier air behind the front.
Mainly above normal temperatures will be evident through the period,
with highs reaching the 80s each day.
Aviation 15z Thursday through Monday
Southwest low level jet of 25 to 30 kts was resulting in the
development of scattered showers and thunderstorms this
morning. This axis of lift will pivot north through the taf
sites early this morning. These storms will bring brief MVFR
vsbys and cigs. After the passage of this initial axis of
convection expect mainlyVFR conditions through the remainder of
Better coverage of storms is expected to occur this afternoon
as moderate instability and pre-frontal trof axis moves into the
region. MVFR to brief ifr vsbys possible in these storms.
Storms to end late this evening with the front pushing east
through the area overnight. As clouds diminish fog and stratus
development will be possible toward daybreak Friday. At this
time have just a mention of MVFR visibilities but ifr CIGS are
not out of the question in the mixed boundary layer.
Southwest winds at 10 to 15 kts will gust up to 25 kts today.
Outlook... Fog and possible status to improve Friday morning.

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 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.
