Synopsis
Issued at 644 am edt Mon oct 15 2018
scattered light rain showers will end by midday, followed by at
least partial clearing this afternoon. It will be quite chilly
later tonight with low temperatures near the freezing mark and
frost expected by early Tuesday morning. The cool pattern
continues through the week with afternoon highs primarily in the
50s and overnight lows in the 30s.

Short term (today and tonight)
issued at 436 am edt Mon oct 15 2018
cold front generally bisected the area from monticello NE to
coldwater. Light showers drizzle was noted either side of the
front with more extensive showers from N il into southern lk mi.

To the southwest an ohio valley disturbance was causing showers to
stream northeast across central in. Have adjusted pops to account
for these trends with precip winding down by mid morning. Gusty nw
winds will usher in cooler temps with cloud cover likely to linger
into this afternoon before drier air mixes in from west to east.

Not a lot of diurnal temperature difference expected with brunt of
caa moving in during peak heating. Highs will only be in the mid
40s NW to low 50s SE and this will come mainly this morning with
steady or falling temps this afternoon.

Focus then shifts to tonight as coldest night of the fall looks to
settle across the area. As sfc ridge axis aligns across southern
il in. Clear skies will dominate providing plenty of radiational
cooling. With lows forecasted to drop into the low 30s a hard
frost partial freeze is possible in some areas. However models
suggest sfc winds may remain above 4 kts for all but areas south
of us-24. While confidence is somewhat higher than past setups,
don't want to lock day shift into something that could need
changing later. After collaboration with surrounding offices will
hold off on any headlines. Will continue mention in hwo.

Long term (Tuesday through Sunday)
issued at 436 am edt Mon oct 15 2018
another northern stream wave will drop in Tuesday night into weds
to bring reinforcing shot of cold air and increase in clouds,
mainly in lake effect areas. Can't rule out a few lake effect
showers in the wake of the system, but main potential for this
will likely remain north of the area. Weds ngt through Fri will
see quiet conditions with only concern being yet another chance
for frost weds ngt.

Upper level trough will finally eject off the new england coast by
Thursday with moderation in temps expected as heights increase
ahead of longwave trough over western plains. As this ejects to
the east it will attempt to phase with a potent northern stream
wave dropping south by Friday. This will bring some return in
moisture and at least a chance for showers to the area into the
weekend. Models do vary on when if phasing occurs and degree of
cold air that may arrive behind the system.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 645 am edt Mon oct 15 2018
fairly widespread ifr conditions, primarily due to ceiling
heights across northern indiana, though upstream drier air will
eventually advance eastward through late morning. Deeper
mixing steep low level lapse rates for turbulent post frontal wind
field and deep layer subsidence to lend a west to east
improvement through the early afternoon hours across northern
indiana.

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.
