Area Forecast Discussion
National Weather Service Northern Indiana
333 AM EDT Sun Sep 3 2017

.SYNOPSIS...
Issued at 333 AM EDT Sun Sep 3 2017

Dry and mostly sunny conditions are expected today with highs in the
upper 70s to near 80. Labor Day will be even warmer with highs in
the mid to upper 80s. A cold front will arrive late in the day with
scattered thunderstorms possible. A few of these storms may be
severe with damaging straight line winds the primary threat. Much
cooler temperatures and periodic light rain showers expected for the
middle of the week.

&&

.SHORT TERM...(Today and Tonight)
Issued at 333 AM EDT Sun Sep 3 2017

Dry and pleasant weather anticipated today. Mid/upper level trough
axis (and associated light rain showers) quickly exiting this
morning with strong AVA/subsidence and quickly building heights in
its wake. Negative theta-e advection in NW flow will scour out low
level moisture later this morning. A few cu/stratocu may linger in
our eastern zones but by and large expect a mostly sunny afternoon.
Winds begin to back late today with some weak WAA and full
insolation allowing late afternoon highs to make a run at 80F. WAA
really cranks up overnight though as high pressure shifts to the
southeast CONUS and WSW gradient tightens locally. Given this and
warmer start to the evening, expect lows only around 60F despite
mostly clear skies.

&&

.LONG TERM...(Monday through Saturday)
Issued at 333 AM EDT Sun Sep 3 2017

Monday still looking warm and windy with potential for storms late
in the day. Low level gradient tightens substantially on Monday as
longwave trough starts to dig into the Great Lakes/Ohio Valley.
Strong WSW flow peels off part of western thermal ridge and advects
it into our area with a narrow corridor of 850mb temps surging above
20C. Average 850mb temps closer to the mid teens though and still
some question about how high we will be able to mix given strong
inversion seen on NAM and GFS forecast soundings, as well as lower
Sep sun angle. Most of the morning/early afternoon should be cloud
free and continued to lean on warmer guidance with mid to upper 80s.
Winds will also be gusty. Max boundary layer winds still close to 40
kts, suggesting some gusts around 35 mph possible (outside of any
convective component).

Other main concern will be severe weather potential. Fast-moving
cold front will arrive during the late afternoon/early evening with
enough low level convergence/moisture pooling to support SCT
convection. Surface dewpoints expected to be in the mid (to perhaps
upper) 60s. Raw GFS and NAM dewpoints running a little high as usual
but modified soundings still yield roughly 1000-1500 J/kg of 0-1km
MLCAPE. Moisture quality is a bit dubious with such a narrow
corridor but even MOS guidance indicating some potential for upper
60s dewpoints. Midlevel temps also on the warm side but this should
be overcome with adequate low level moisture and most models now
showing at least a broken line of convection developing in our area
early Monday evening. With such an impressive low/midlevel wind
field, it will not take much to support damaging wind gusts given
unidirectional 40-50 kts largely orthogonal to the front. Moisture
and instability profiles are questionable this far out but if
current trends hold, scattered severe storms will be possible late
Monday with damaging straight-line winds the primary threat.

Will turn much cooler and very fall-like for the middle of the week.
Highly amplified large scale pattern will set up over much of
northern hemisphere with sharp ridge over western NOAM and deep
trough centered over our area. 850mb temps crash into the low single
digits with cyclonic northerly flow favoring abundant clouds and SCT
showers, especially with added contribution of very warm lakes.
Expect highs in the 60s and lows in the 40s at least Tue-Thu. Temps
slowly moderate (along with drier conditions) heading into next
weekend.

&&

.AVIATION...(For the 06Z TAFS through 06Z Sunday Night)
Issued at 210 AM EDT Sun Sep 3 2017

A band of light showers/sprinkles associated with an upper level
short wave has shifted east of the terminals as of 06Z. Dry
conditions are expected for the remainder of the night with no
discernible upstream short wave of note. Broad low level
anticyclone will remain anchored west of the area today which
should allow for west-northwest wind component once diurnal
mixing commences after 14 or 15Z. Wind speeds should generally be
around 10 knots with a few gusts into the 14 to 17 knot range
possible during the day. Winds to become light southwest with loss
of mixing this evening, but should pick up again to around 10
knots toward late overnight Sunday night as gradient begins to
strengthen ahead of a front that will impact the area Monday.
