The High Plains and portions of Texas will become the targets of spotty, but violent storms Friday evening.
Northeastern Colorado, northwestern Kansas and western Nebraska have the greatest threat for very large hail and tornadoes.
Damaging wind gusts higher than 60 mph, frequent lightning and locally flooding downpours are other concerns.
Meanwhile, thunderstorms will stretch southward to Texas during the evening. Torrential downpours appears to be the biggest concern with the storms that will erupt across west-central and southern Texas. However, damaging wind, large hail and isolated tornadoes can also occur in the strongest storms that develop. San Antonio is among the communities at risk for violent thunderstorms.
The threat of spotty late afternoon and evening severe storms in the High Plains exists through the Memorial Day weekend. It is crucial for those celebrating the holiday with outdoor festivities to stay alert of the possibility of rapidly changing weather conditions. Check back frequently with the AccuWeather Severe Weather Center for severe thunderstorm watches and warnings.
A more organized and widespread severe storm risk will arrive by the middle of next week.
"There is a possibility of a severe weather outbreak beginning Wednesday over the High Plains, spreading eastward over the lower Plains and Mississippi Valley Thursday into Friday," AccuWeather Expert Senior Meteorologist Alex Sosnowski said.
