Update
The aviation section has been updated below.

Synopsis
Issued at 310 am edt Sun mar 26 2017
a few low pressure systems will move through central indiana during
the next week, bringing frequent chances for showers and some
thunderstorms to the area. Temperatures will remain near to above
average into next weekend.

Near term /today/
issued at 310 am edt Sun mar 26 2017
rain was falling across much of central indiana early this morning,
thanks to upper and surface lows back near the mississippi river.

The lows will move into lower michigan by this evening. The current
widespread rain should shift east some by morning, but latest hi-res
models indicate that the northeastern 2/3 of the area should still
be seeing rain. Will go categorical pops northeast half tapering to
chance pops southwest at the start of the today period.

This first band will continue to shift off to the east during the
morning, but the hi-res models as well as ensembles show another
round of rain developing midday as a surface front moves through and
an upper jet moves in. This will bring more likely pops to the area.

Will try to time a break between the areas of rain where possible.

Pops will then diminish west to east during mid afternoon to early
evening as the system begins to exit the area.

There will be some instability so will continue with a thunder
mention.

Went a little above the model blend for high temperatures most areas
based on latest performance.

Short term /tonight through Tuesday night/
issued at 310 am edt Sun mar 26 2017
models are close enough that the model blend initialization
was accepted for most items.

Will include some low pops this evening east to account for any
lingering rain from the existing system. The area should remain in
between systems overnight, so continued a dry forecast then.

An upper trough and another surface low will move in for Monday and
Monday night. Again with this system moisture and forcing look good.

Will go likely or higher pops most areas by Monday afternoon and
across all areas Monday evening.

Based on the expected path of the surface low, it looks like
sufficient shear and instability will work into the southern half or
so of the forecast area for the potential for a few severe storms
Monday afternoon and evening. Thus the storm prediction center has
placed parts of the area in a marginal and slight risk for this
period.

Kept some low pops Tuesday as the system exits, then dry weather
should return.

The model blend temperatures look ok through the period given the
expected path of the system. Will have to keep an eye out on Tuesday
though as some models indicate colder air than the blend suggests
working into the northwest forecast area.

Long term /Wednesday through Saturday/
Issued at 229 am edt Sun mar 26 2017
ecmwf continues to suggest strong ridging across the area on
Wednesday as large but poorly defined areas of surface high
pressure move across the great lakes... Ohio valley and the
southeastern states. This will lead to dry weather on Wednesday.

Meanwhile... Strong low pressure will be developing across the
southern plains. ECMWF moves this system toward indiana on
Thursday afternoon through Friday. With favorable dynamics in
place aloft including a strong and sharp upper trough... Have
included high likely pops at that time.

Ecmwf then suggests strong ridging building across the area on
Friday night and Saturday along with strong subsidence and the
arrival of another high pressure system. Thus dry weather is
expected then.

Aviation /discussion for the 261200z tafs/
Issued at 611 am edt Sun mar 26 2017
MVFR conditions are expected this morning. Improvement toVFR is
expected this afternoon.

Low pressure remains west of indiana as rain and MVFR CIGS within
the warm conveyor belt ahead of the low continue to stream across
the TAF sites. Forecast soundings and time heights continue to
suggest this deep moisture will persist the next several hours as
the low slowly tracks NW of the TAF sites.

As dry air continues to intrude into the system... Precip should
move east of the TAF sites allowing more sct-isolated showers
along withVFR CIGS this afternoon. Forecast soundings at that
time trend toward more dry air intruding in to the column at that
time. Weak ridging is then expected to build briefly across
indiana overnight.

Ind watches/warnings/advisories
None.

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.
