Synopsis
Issued at 127 am edt Mon mar 27 2017
rain chances will increase later this afternoon and tonight as
another system approaches from the west. An isolated thunderstorm
is also possible tonight. Dry conditions are expected from
Tuesday afternoon through Wednesday evening before another storm
system brings increasing chances of rain for late Wednesday night
through Friday. High temperatures today will range from the lower
to mid to upper 50s across southwest lower michigan, to the lower
to mid 60s across northwest ohio. Lows tonight will range from
then lower 40s to around 50.

Update
Issued at 1135 am edt Mon mar 27 2017
forecast generally on track with little more than some patchy
drizzle into early afternoon. Band of light showers was working
northeast from southern il/in along a warm front. Hrrr shows this
area work north and fall apart with much larger area over sw
illinois associated with the main upper low to migrate NE and
bring steady rain late this afternoon into early evening. Same
models suggest convection to the south may rob better inflow of
moisture and bring precip to an end quicker than currently
depicted. Leaving forecast alone for now, but may need to adjust
trends with afternoon forecast.

Breaks in the clouds and eventually arrival of warm sector should
yield highs near or into the 60s for SE half of so of the area.

Short term (today through Tuesday)
issued at 438 am edt Mon mar 27 2017
the second upper level system to move across the area in as many
days will bring another round of showers to the area later today
through tonight. Some mainly elevated instability will bring a
slight chance for storms mostly south of highway 30. Severe storms
are not expected given weak dynamics and very limited surface based
or elevated instability. Rainfall amounts through Tuesday morning
should be around a quarter of an inch or less. Mild weather will
persist with highs today and Tuesday in the 50s and 60s.

Long term (Tuesday night through Sunday)
issued at 438 am edt Mon mar 27 2017
cool air will spread across the area Tuesday night behind a cold
front as a large high pressure area builds south out of canada.

Lows Tuesday and Wednesday nights will dip into the 30s. The gfs
has moderated lows from earlier runs, with lows in the 30s. Kept
temperatures above freezing except for hillsdale county with lows
of 32 degrees both nights. Given thermal profiles, the
precipitation at the onset of the next system appears early
Thursday to be all rain. Some model soundings are close to
freezing rain with a very large warm layer; however, feel there
will not be any weather impacts. Rain should end by the weekend
with highs climbing back to around 60 by Sunday.

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.
