Area Forecast Discussion
National Weather Service Northern Indiana
624 AM EDT Wed Oct 26 2016

Issued at 308 AM EDT Wed Oct 26 2016

A few showers will overspread western areas through daybreak
before dissipating otherwise it will remain cloudy. Temperatures
will struggle to rebound north with highs only in the mid to upper
40s...with mid to upper 50s south. More widespread showers are
expected to develop ahead of a cold front late this afternoon and
spread eastward through this evening.


.SHORT TERM...(Today through Thursday)
Issued at 308 AM EDT Wed Oct 26 2016

Upstream arc of shra contained within warm air advection zone
continue to languish with ern extent and suspect most of this will
decay to sprinkles as it translates east into nw OH by daybreak.
More erstwhile development this morning located well west in
advance of sfc low and attendant frontal zone over central IA in
an area of more robust low level moisture flux/theta-e ridging.
This will work east into the area late this afternoon and evening
with an isolated thunder chance over wrn zones.

Otherwise showers end after midnight ern areas followed by sfc high
pressure Thu.


.LONG TERM...(Thursday night through Tuesday)
Issued at 308 AM EDT Wed Oct 26 2016

Active nrn stream flow across southern/central Canada projects a
mild zonal flow across the Conus this period. Trailing southward
extent of washing sfc frontal zones in association with disturbances
passing well north through se Canada of little concern given limited
low level moisture return. Otherwise well above normal temps
expected through the period.


.AVIATION...(For the 12Z TAFS through 12Z Thursday Morning)
Issued at 623 AM EDT Wed Oct 26 2016

Area of light rain/sprinkles will continue this morning,
especially at KSBN, as warm advection wing tied to an approaching
upper trough lifts through. Low levels will remain dry resulting
in VFR ceilings generally btw 5-10 kft. A lull in rain coverage is
expected late morning through mid afternoon before more pronounced
frontal forcing/moisture advection arrives into KSBN late
afternoon/evening and KFWA this evening/early overnight. Heavier
showers and restrictions should accompany this moisture/UVM plume,
especially at KSBN north of sfc reflection anticipated to track
east through northern Indiana tonight. Better forcing/isentropic
lift shifts east after midnight but will likely see
drizzle and IFR stratus/BR linger near weak sfc refection.
Otherwise, easterly winds 10-20 knots (with higher gusts) can be
expected today


LM...Small Craft Advisory until 11 PM EDT this evening for LMZ043-046.
