Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0241 PM CDT Sun Apr 01 2018
Valid 012000Z - 021200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are possible over the Ozarks and Mid Mississippi
Valley, as well as over parts of central Florida.
...Discussion...
No appreciable changes to thunder probabilities are warranted.
Scattered elevated convection continues across southern MO within
favored warm advection zone. This activity should spread toward the
confluence of the OH/MS Rivers as westerly flow will maintain
sufficiently steep lapse rate environment into this region.
..Darrow.. 04/01/2018
.PREV DISCUSSION... /ISSUED 1117 AM CDT Sun Apr 01 2018/
...Oklahoma/Kansas into the Mid Mississippi Valley...
A well-defined shortwave trough over WY/CO will track eastward
across the central Plains and into the mid MS Valley later tonight.
Lift ahead of this system will result in scattered showers and
isolated thunderstorms from parts of eastern KS/OK eastward into
western KY/TN. Forecast soundings suggest that lightning activity
will be quite limited, but elevated CAPE may be sufficient for
charge separation in the strongest cells.
