Synopsis
Issued at 351 pm est Mon dec 16 2018
a ridge of high pressure will keep skies clear to partly cloudy
today with highs close to the normal around 40. Cloud cover will
be increasing Wednesday ahead of a strong low pressure system than
will bring a good chance for rain from late Thursday through
Friday.

Short term (today and tonight)
issued at 344 am est Tue dec 18 2018
a large high pressure area was over the upper great lakes region
early this morning and extended into the midwest. This system
will help keep skies clear to partly cloudy with seasonally
temperatures through tonight. Highs today should be near the
normal around 40.

Long term (Wednesday through Monday)
issued at 344 am est Tue dec 18 2018
an unsettled pattern is ahead later this week as an upper level
trof amplifies over central north america. A lot of energy will be
in the base of this system along the gulf coast Thursday. The bulk
of this system will stay southeast of the area as the lows track
over the appalacians Friday. Thermal profiles over indiana continue
to indicate limited potential for accumulating snow over the
forecast area with this system given limited cold air and a more
southeast track. At this time, significant travel issues are not
expected, although some roads may become slippery late Friday
night as colder air spreads across the area causing temperatures
to fall below freezing by Saturday morning. Otherwise, a weak lake
response may bring some light lake effect rain or snow showers
this weekend, but little if any snow accumulation is expected.

Aviation (for the 12z tafs through 12z Wednesday morning)
issued at 525 am est Tue dec 18 2018
vfr mainly clear skies and light winds are expected through the
taf cycle.

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.
