Strong storms possible on Sunday, May 19th.

There's a good chance for strong storms tomorrow. I don't think it would be a good idea to go to Bryan Park for a picnic tomorrow just in case any organization in town happens to be thinking about it.

Discussion from the NWS:

.SHORT TERM /Tonight through Monday Night/...
Issued at 346 AM EDT Sat May 18 2019

Forecast challenges focus on a stormy Sunday with a severe weather
threat for the afternoon and early evening.

The upper low kicking out of the northern Rockies will sharpen
tonight with a new piece of energy developing over the central
Plains this evening. This will prompt a new surface low organizing
over the Missouri Valley this evening then tracking northeast into
the Great Lakes Sunday as the upper low lifts into the Upper
Midwest. The upper trough will take on a negative tilt as it lifts
through the area Sunday afternoon and combined with a cold front set
to track through the area late day...pronounced threat for severe
convection is in play for central Indiana.

Convection that develops out over the central Plains late today
into the evening will shift east and should arrive into the Wabash
Valley during the predawn hours Sunday morning in a weaker state.
Showers and storms will track east across the forecast area
through early afternoon aided by a strengthening 50-60kt low level
jet that will advect an axis of much deeper moisture into the
Ohio Valley and should maintain a higher coverage of rain and
storms over the region. Outside of showers and storms...the strong
low level jet will ensure potential for gusts to peak near 40 mph
Sunday afternoon.

Morning convection should largely shift east of central Indiana by
mid afternoon with a narrow dry slot between the departing
convection and the approaching cold front. This dry slot will be key
in developing a short window of just a few hours focused on the late
afternoon and early evening where the atmosphere will become
supportive of robust convective development along and immediately
ahead of the front. The NAMNest and the WRF models all suggest
redeveloping convection that should organize into a line or a couple
of smaller lines as it tracks east through the forecast area. With
modest instability and an axis of higher BL shear and helicity ahead
of the front along with continued strong low level winds and
diffluent flow aloft...growing support for late day storms to carry
all modes of severe weather with the main threat of damaging winds.
Large hail will be a secondary concern as wet bulb zero levels drop
into the favorable 8-9kft level. Does appear enough directional
shear will be present for rotating storms as well.

Storms will shift east with the cold front Sunday evening...with
cooler and drier air arriving with high pressure late Sunday night
into Monday. Expect a breezy start Monday with winds gradually
slackening through the day as the high builds into the Ohio Valley.
Will be some diurnal cu development on Monday with cold advection in
the wake of the frontal passage...but expect plenty of sunshine as
well. Northwest winds Monday will veer to north/northeast Monday
night as the high passes through the Great Lakes.

Temps...Leaned much closer to the warmer MAV guidance Sunday but
more clouds and a greater threat for rain will keep much of the area
in the 70s. Cooler MET guidance is preferred for MOnday as low level
thermals support highs generally in the 60s. After a muggy night
tonight in the 60s...lows will fall back as low as the mid and upper
40s by Monday night.
