Synopsis
Issued at 140 am edt Fri sep 21 2018
there is a chance of showers across northwest indiana and
southwest lower michigan toward daybreak, with a few embedded
thunderstorms possible. The chance of showers and storms will
shift east across the remainder of the area during the day, with
the best chance from midday through late afternoon across extreme
northeast indiana and northwest ohio before a cold front shifts
east of the area. Otherwise sharply cooler temperatures and dry
weather expected this weekend. Highs will only reach into the 60s
on Saturday, then in the 70s next week.

Short term (today and tonight)
issued at 303 am edt Fri sep 21 2018
gusty winds and low chances for showers storms the story today as
potent mid level shortwave and deepening sfc reflection northeast
through the northern lakes and southeast ontario sends a trailing
cold front through the local area. Pre-frontal convective outflow
boundary may allow for a decaying narrow line of showers iso
thunder to survive into areas mainly west of i-69 this morning
(11-16z). The main cold front then nears the i-69 corridor toward
18-19z... Then clears our oh counties to the east by around 21z.

Moist low levels and some support aloft could allow for a narrow
line of sfc based convection to re-fire along this cold front
during this time. An isolated strong-severe storm cannot be ruled
out given the potential for 1500 j kg of MLCAPE and 35 knots of
deep layer shear, especially along and southeast of a portland in
to napoleon oh line 19-21z.

Good post-frontal cold advection and drying will lead to quiet and
much cooler conditions tonight as low temps fall into the upper 40s
to mid 50s.

Long term (Saturday through Thursday)
issued at 303 am edt Fri sep 21 2018
high pressure will build in under flattened flow for this weekend
with fair weather and below normal temperatures. Pattern becomes
more active next week as broad longwave troughing sets up over the
north-central us. This process will sent one cold front through
around Monday night-Tuesday and then another toward the end of the
week with decent chances for rain embedded thunder... Especially
Monday night-Tuesday given ample moisture return and favorable upper
jet support. Temperatures will generally be relatively close to
where they should be in late september otherwise.

Aviation (for the 12z tafs through 12z Saturday morning)
issued at 559 am edt Fri sep 21 2018
pre-frontal confluence zone, enhanced by residual approaching
outflow boundary from last night's upstream convection, has been a
focus over the past few hours of increasing shower embedded
thunderstorm coverage from east central illinois to the southeast
shores of lake michigan. This forcing should shift across
northwest indiana over the next few hours with a period of showers
and possibly a few thunderstorms at ksbn. Llws conditions should
persist the longest at kfwa in pre-frontal environment, and will
carry this mention through 14z before low level mixing diminishes
this potential. Thunderstorm potential remains of low confidence
at kfwa with possibility of early morning showers diminishing with
pre-frontal forcing, and potential that redevelopment along the
cold front may occur just east of kfwa. Will likely continue to
carry vcts mention in the 16z-20z timeframe at kfwa. Otherwise for
today, southwest winds to becoming gusty with gusts to around 25
knots ahead of the front, followed by post-frontal westerly gusts
to 25 to 30 knots through the mid-late afternoon hours. Gusts
should diminish early this evening. Quiet aviation weather
expected tonight as much drier air advects 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.
