Synopsis
Issued at 308 pm edt Mon jul 22 2019
-comfortable conditions tonight!
-chance of storms tomorrow afternoon
- dry Wednesday through Friday

Discussion (this evening through next Monday)
issued at 308 pm edt Mon jul 22 2019
low pressure moving across ohio is producing showers storms south of
the state. A well defined cirrus edge was noted from near port huron
southwest to south bend and its moving east. Diurnal CU was noted
north of there across much of the cwa. This CU will dissipate toward
sunset and wind will decrease. A very comfortable night is expected
with dewpoints in the 40s and lows in the lower to mid 50s.

The next chance of rain will be tomorrow afternoon. ECMWF and gfs
show a short wave dropping south and namnest points toward scattered
showers storms east of us-131 after noon. H5 temps in the mid teens
tomorrow afternoon will create moderately steep lapse rates. Given
li's near -7c and SBCAPE near 1200 j kg, we could see some storms
fire with lift generated by the short wave. Moisture may be a
limiting factor though. However if the storms get going, a few
hailers are possible, given the cold temps aloft; something to watch
for. Behind the short wave, the upper ridge will start to move back
in and we'll have a couple of days of dry weather Wednesday through
Friday. Another cold front will drop south and give the northern cwa
a chance for a storms, but chances are not all that high. The
highest chance of rain will come Monday, if model timing is correct,
which it probably isn't this far out.

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.
