Tuesday's Severe Weather Update

I want to take this opportunity to add to what Ted wrote in his previous blog entry about this week's severe weather. Spring time is all about the location of the jetstream. The placement of the jet is crucial for severe weather development; moreover, our window of opportunity will be late Tuesday afternoon and evening for strong to severe storms.
Our next jetstreak is currently moving out of California toward the desert southwest. This tightly packed bundle of winds around 30,000 ft could be as strong as 130 knots. These types of winds will ultimately lead to strong upward vertical velocities, and explosive severe thunderstorm development. Look for the central Oklahoma dryline to provide the initial focus for storms by Tuesday afternoon.
Wind shear will be every high by Tuesday evening across SE OK and SW AR. Storm motion will be very fast, moving from the SW to NE. Storms that fire across SE OK will have the chance to move toward the River Valley. Large hail and isolated tornadoes can't be ruled out with the strongest storms. The best tornado threat at this point looks to be along and south of I-40. ***Please take a look at where the tornado threat exists in relation to the jetstreak.***
This would be a good time to review your severe weather safety plan with your family. It has been a few weeks since we've seen severe weather, so make sure everybody knows where to go when severe weather strikes. More updates to come!
