Synopsis
Issued at 500 am edt Sat mar 25 2017
upper level disturbances will move northeast along a stationary
front this weekend and bring chances for showers and storms
through Sunday. Rain will become more widespread Sunday as the
upper low moves over the area. Highs south of the front over much
of northern indiana will reach the 60s to around 70s today, with
only 40s and 50s north of the front.

Short term (today through Sunday)
issued at 500 am edt Sat mar 25 2017
a deep upper low was over eastern oklahoma early this morning
with a stationary front extending northeast from the associated
surface low into northwest indiana. The marine layers of both lake
michigan and lake erie were accentuating the cold air behind the
front given lake water temperatures in the 30s. Have lowered highs
in the northeast corner of the forecast area from hillsdale to
wauseon where an east flow was spreading chilly air west. Given
this scenario, these northeast highs may still be too warm.

Otherwise, impulses from the upper low will move northeast and
bring more showers and storms to the area, especially over
northwest indiana and far southwest lower michigan. The upper low
should lift over the forecast area by late Sunday favoring
widespread showers and storms. Severe weather is not expected,
but locally heavy rainfall may cause limited flooding.

Long term (Sunday night through Friday)
issued at 500 am edt Sat mar 25 2017
a series of upper level system will eject northeast out of the main
upper trof this upcoming week and bring several chances for rain
through Friday. The best chances for rain over the forecast area at
this time will coincide with the arrival of these short wave trofs
and appear to be Monday night and then Thursday through Friday.

Temperatures will be above normal each day with a high chance for
readings staying above freezing all of next week. Severe weather
chances appear low, but rainfall amounts this upcoming week may
total more than an inch.

issued at 626 am edt Sat mar 25 2017
cdfnt extending from east to west across NRN oh-in expected to
sag just slightly south today as strong high over ontario moves
east to quebec. Vertically stacked low over the SRN plains
advecting moisture n-ne along this frontal boundary resulting in
shra and isolated ts. Ifr conditions have been becoming more
widespread north of the frontal boundary early this morning. Not
much improvement expected in flight conditions at sbn which should
remain on the north side of this boundary today, with conditions
likely deteriorating further tonight as ocnl shra cont. Fwa will
likely remain on the warm side of the boundary but moisture will
be increasing as the low approaches with shra likely by tonight,
causing flight conditions to lower to ifr.

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.
