Synopsis
Issued at 315 pm est Tue nov 21 2017
showers will end this evening as a cold front moves out of the
area. Lows tonight should dip to around 25 degrees. Colder and
dry weather is ahead for Wednesday as high pressure builds into

continue Thursday and Friday with mild weather. Highs should be
near 50 Friday.

Short term (this evening through Wednesday)
issued at 310 pm est Tue nov 21 2017
a cold front was over far southwest lower michigan into northwest
indiana this afternoon. A strong upper level system with favorable
upper level jet dynamics were able to overcome a very dry
environment and produce an area of rain in the vicinity of the
front. The best upper level support was north of the michigan line
where rainfall amounts exceeded a tenth of an inch. Rainfall
amounts mainly under 0.05 inch are expected over indiana and ohio
before midnight. Very low inversion heights should prohibit a lake
response of lake effect rain or snow showers. High pressure will
continue to build in Wednesday with decreasing clouds and cold
weather.

Long term (Wednesday night through Tuesday)
issued at 353 pm est Tue nov 21 2017
fairly tranquil weather is ahead this weekend into early next
week. Another cold front will bring a chance for showers Friday
night after a brief warmup Friday. Little if any rainfall is

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
