Area Forecast Discussion
National Weather Service Northern Indiana
1902 PM EDT Sun Jul 1 2018
.SYNOPSIS...
Issued at 1902 PM EDT Sun Jul 1 2018
Hot and humid this afternoon. An isolated strong to severe storm is
possible toward mid evening west of US 31 with a few showers or
thunderstorms possible overnight elsewhere. Lows tonight will range
in the lower 70s.
&&
.SHORT TERM...(Tonight and Monday)
Issued at 1902 PM EDT Sun Jul 1 2018
Primary concern relegated to decaying sfc front pushing out of IL
this evening. 12Z gross trend similar with prior guidance in
collapsing frontal scale circulation across wrn zones mid to late
evening before washing out through cntrl zones aft midnight as
parent sw disturbance lifting well nw through MN. Convective
processes within line of storms over wrn IL might carry left overs a
bit further east this evening otherwise better low level forcing may
manifest toward daybreak from cntrl-ern zones in association with
modest low level jet juxtaposed within H85 theta-e ridge.
Nevertheless given even trends in guidance a general reduction in
pops made overnight.
Stalled left over frontal zone and diurnal destabilization may
initiate isolated storms se half Mon aftn in prolixity to low level
theta-e plume before low level flow weakens late.
&&
.LONG TERM...(Tuesday through Saturday)
Issued at 1902 PM EDT Sun Jul 1 2018
Upper ridge over the wrn atlantic to start will slowly retrograde
wwd into the cntrl plains by early Fri. Nrn stream sw disturbance
digs into the nrn Rockies Tue as high plains cyclogenesis commences.
Some downstream influence noted here with backing low level flow to
serly and with plume of unstable low level theta-e still in place
cant argue for at least an isold pop mention however bulk boundary
layer moisture flux remains weak and does not justify high chance
pops.
Thereafter upper ridge builds in earnest esp Wed-Thu. Warming mid
level temps along with erosion of low level theta-e ridge and anemic
flow aloft in aggregate suggest dry/hot and humid. Rockies
disturbance kicks out into srn Canada Wed and into wrn QB early Fri.
Attendant sfc trough washes out across the lakes but with some
flattening of upper ridge. This will allow for some decent airmass
exchange next weekend with much drier and seasonable air to spread
south out of se Canada.
&&
.AVIATION...(For the 12Z TAFS through 12Z Monday Morning)
Issued at 606 AM EDT Sun Jul 1 2018
Another dry/mainly VFR day is in store today. Thunderstorm
chances return this evening as an upper wave lifting northeast
toward the Western Lakes drives a weakening frontal zone into
northern Indiana. Opted for a VCTS mention at KSBN after 00z for
40-50 percent type PoPs and held with a dry forecast at KFWA
given later/poor timing.
