MD 0805 CONCERNING SEVERE THUNDERSTORM WATCH 247... FOR EASTERN ILLINOIS AND WESTERN/CENTRAL INDIANA
MD 0805 Image


Mesoscale Discussion 0805
NWS Storm Prediction Center Norman OK
1224 AM CDT Sun May 26 2019

Areas affected...Eastern Illinois and Western/Central Indiana

Concerning...Severe Thunderstorm Watch 247...

Valid 260524Z - 260630Z

The severe weather threat for Severe Thunderstorm Watch 247
continues.

SUMMARY...A wind damage and hail threat will be likely across
eastern Illinois and western to central Indiana over the next few
hours. Weather watch issuance will probably be necessary shortly.

DISCUSSION...The latest radar imagery shows a strong to severe short
line segment across central Illinois. A pocket of moderate
instability is analyzed by the RAP from south-central Illinois
extending eastward into south-central Indiana. The line segment will
continue to move eastward along the northern edge of moderate
instability into western and central Indiana over the next 2 to 3
hours. In addition to the instability, the WSR-88D VWP at
Indianapolis shows about 40 kt of 0-6 km shear with westerly
unidirectional flow in the lowest levels. This will support an
isolated wind damage threat. Hail will also be possible with the
stronger cores.

Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0741 PM CDT Sat May 25 2019

Valid 260100Z - 261200Z

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS EVENING
ACROSS PARTS OF WESTERN OKLAHOMA AND CENTRAL/EASTERN KANSAS...

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS EVENING NEAR
THE ALLEGHENY FRONT AND PORTIONS OF THE SOUTHERN TIER OF NEW YORK...

...SUMMARY...
A risk for severe thunderstorms continues this evening, mainly
across southern portions of the central Plains into portions of the
middle Mississippi Valley, and across portions of western New York
and Pennsylvania into the Allegheny Mountains.

...01Z Outlook Update...

...Southern/central Plains into middle Mississippi Valley...
The leading edge of conglomerate convective outflow associated with
upscale growing convection may maintain vigorous thunderstorm
development along its northeastward surging leading edge, across
parts of western/northern Oklahoma and central/eastern Kansas,
through at least the 02-04Z time frame.  This will be supported by
modest inflow of air characterized by CAPE on the order of 2000-3000
J/kg, in the presence of strongly sheared, 30-40 kt southwesterly
mean ambient flow.  

Similar instability may continue to support additional strong/severe
thunderstorm development through late evening in advance of this
activity, along the primary surface frontal zone extending across
northern Kansas, east-northeastward across southern Iowa, into
southern portions of the Great Lakes region.

Stronger southerly 850 mb flow, on the order of 30-40+ kt, will
remain focused across the Texas South Plains into the central High
Plains, around the western periphery of  subtropical ridging
centered near the eastern Gulf Coast states.  This will provide
potential for further thunderstorm development above the residual
convectively generated cold pool across the Texas Panhandle, but
this may occur well to the north of the southern outflow boundary,
as increasingly warm and capping elevated mixed-layer air advects
north-northeastward across the southern into central High Plains.

...Northeast...
To the southeast of the lower Great Lakes region, an increasingly
organized squall line has evolved across portions of western New
York and Pennsylvania.  However, as it continues eastward across the
Southern Tier of New York, and across the Allegheny Front, it will
encounter stable boundary layer air which appears likely to lead to
fairly quick diminishing trends in intensity and severe weather
potential by 02-03Z.
