Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Pittsburgh, PA (KAGC), launched 00:00Z, 2.8 hours before the alert went out and 174 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Cleveland, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 30, 10:14 PM EDT, 35 minutes earlier.

Area forecast discussion, Mar 30, 10:14 PM EDT, 35 minutes before

Area Forecast Discussion
National Weather Service Cleveland OH
1014 PM EDT Thu Mar 30 2017

.SYNOPSIS...
Low pressure over Indiana will track across northern Ohio on
Friday. A warm front will push northeast ahead of the low this
evening with the front occluding over the area later tonight.
The low will move east of the area by Friday night. High
pressure from the upper midwest will move overhead by Sunday.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...

Convection has diminished in intensity recently with core
heights decreasing along with less lightning. Coverage of the
showers and weak storms has been steady and will likely continue
through the overnight. So we will continue with likely to
categorical POPs with just a chance of thunderstorms until about
06UTC. Overnight temperatures will be rather steady in the
northwest near TOL and rise slowly in the eastern and central
counties as the surface low and attendant warm front gradually
move into the CWA.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
The low pulls away to the east by Friday night showers will linger
across the eastern half of the area into the evening with ample
moisture wrapping around the back side of the system. As low
level flow shifts around to the north much cooler air will be pulled
south across the area. Showers should finally diminish by Saturday
morning with clouds trying to scatter out from the northwest late.
With the flow on the lake, highs on Saturday will range from the mid
40s to near 50 unless we clear out sooner. High pressure will build
southeast across the area on Sunday with mid cloud already on
the increase.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
Alternating ridge and trough cycle will continue through this
forecast period. Upper level trough moves into the local area Monday
with a resultant surface low pressure that will move northeast
through the Ohio Valley region.  This feature will bring more mild
temperatures and another round of showers to the area. As the low
passes by the area Tuesday, some weak cold air advection will take
place as weak ridge of high pressure builds southeast into the area.
Fast moving ridge moves east over the area as well. This will bring
fair weather to the region but will be short lived for Tuesday
afternoon into Wednesday.  Then, yet another deep digging upper
level low pressure system and associated trough will move east
across the area with another resultant surface low pressure system.
Once again, this system will spread more rain into the area Thursday
into Friday.  Only difference, is the upper level feature packs a
little more punch allowing cooler air to pump down into the area and
could bring some light snow by the end of the week.  In the mean
time, mild temperatures will continue through Thursday.

&&

.AVIATION /00Z Friday THROUGH Tuesday/...
Low pressure in MO/IL area with a warm front east into southern
Ohio. The low will continue ENE across Indiana tonight to north
central Ohio by 12z Friday and into nwrn PA by evening Friday.
Given the track of the low do not believe KTOL will get into
the warm sector. May also be tough for KFDY. Otherwise expect
the warm front to lift north across the central and eastern
counties with winds turning sse through the evening.
Thunderstorms will continue to spread into northwest Ohio
through the evening hours. Also that area of storms across east
central Ohio will lift north and affect KCAK KYNG and KERI
through the evening. After midnight expect more showers to lift
north into the warm sector lasting through dawn taking cigs and
vsbys down to IFR/MVFR. Friday expect widespread IFR/MVFR to
continue on the back side of the low.

OUTLOOK...Non-VFR continuing into Friday night. Non-VFR
possible Monday into Tuesday.

&&

.MARINE...
Small craft advisory will need to be extended until 2 AM in the
morning as winds appear they will stay up until then.  Low pressure
is progged to move northeast into the area Friday and push the
lighter gradient north over the lake late tonight.  Winds diminish
as the low passes by but increase again Friday night.  May need
another small craft advisory again Friday night into Saturday
morning.  At that time, winds diminish to light northwest Saturday
afternoon and then variable Saturday night through Sunday night.
Northeast flow will develop again Monday night into Tuesday but
should remain below small craft advisory criteria. Light and
variable winds prevail Tuesday night into early Wednesday ahead of
the next system when winds increase out of the southeast.

This Hazardous Weather Outlook is for north central Ohio, northeast
Ohio and northwest Ohio.

.DAY ONE...This Afternoon and Tonight.

Severe thunderstorms will likely develop in the lower and mid Ohio
Valley this afternoon into tonight. There is a chance that some of
these storms develop farther north so the slight risk of severe
thunderstorms extends into northwest and north central Ohio from

damaging wind and perhaps large hail. An isolated tornado is also
possible, mainly south of a line from Findlay to Ashland. Locally
heavy rain will occur in thunderstorms and multiple thunderstorms in
any spot will increase the threat for flooding.

Locally heavy rain is possible Friday morning, mainly from the I-71
corridor east.
