The severe weather threat for Severe Thunderstorm Watch 647
SUMMARY...A line of storms may continue to pose a damaging wind
threat over parts of central and northeast NE. If the line remains
severe, additional counties may need to be added into the watch.
DISCUSSION...A strong outflow surge coincident with the cold front
continues to push a line of storms rapidly east into central NE, and
now into far northwest KS. Despite a somewhat thin radar
presentation to parts of the line, severe winds are still being
measured at severe sites across southwest NE. Instability remains
favorable, especially over northeast NE where MLCIN is least, with
good low-level inflow with a southeasterly low-level jet. Damaging
winds, or even occasional QLCS structures may develop here.
Farther south, CIN is greater, suggesting a weakening trend is
possible into south-central NE and far northwest KS over the next
