Synopsis
Issued at 344 am est Mon feb 19 2018
very wet and mild weather can be expected into Wednesday. Highs
will rise into the 50s to around 60 today, and then from 65 to 70
Tuesday. Periods of rain with an occasional rumble of thunder will
persist through Tuesday night. In addition to flooding on rivers,
areal flooding is likely, particularly over low lying and other
flood prone areas.

Short term (today through Wednesday)
issued at 342 am est Mon feb 19 2018
the first round of rain has already arrived early this morning as
moisture had surged northeast with many rainfall amounts already
between 0.15" and 0.40" south and west of warsaw by 4 am est.

Periods of rain into Wednesday will cause hydrologic issues with
general amounts between 2 and 4 inches. Higher amounts are
possible where convective bands will likely produce more than 4
inches by late Wednesday. Several factors continue to be very
supportive for moderate to occasionally heavy rain for an extended
period. Precipitable water values per latest GFS will rise above
1.3 inches at times which would top the climatological values for
this time of year. Naefs ensemble mean precip water forecast
values exceed the 99.5% percentile climate into Wednesday,
indicative of the potential for an extreme event. As mentioned
yesterday, an analog from feb 29 to march 5 of 1976 produced 5.45
inches of rain at south bend. Wpc is supportive of of heavy
rainfall with widespread amounts by late Wednesday between 2 and 4
inches. After coordination with surrounding offices, have issued a
flood watch to highlight flooding concerns associated with these
rainfall amounts. There is a good chance highs Tuesday will set
records at both south bend (current record 65) and ft wayne (67).

Long term (Wednesday night through Sunday)
issued at 426 am est Mon feb 19 2018
much colder air will spread across the area Wednesday behind a
strong cold front. Light snow accumulations are possible along
with water on pavement freezing Wednesday night setting the stage
for potential travel issues. Highs will recover into the 40s
Thursday, so any travel issues should end by late morning. More
rain is likely Friday Saturday which will likely aggravate
ongoing flooding issues.

Aviation (for the 18z tafs through 18z Tuesday afternoon)
issued at 1137 am est Mon feb 19 2018
periods of moderate to heavy rain will continue through the entire
forecast period as a strengthening low level jet focuses deep
moisture near a frontal zone draped over the region. Ksbn likely
to remain lifr ifr through the period, while kfwa is expected to
vary between ifr and MVFR.

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.
