Erin Strengthens to a Hurricane; Heavy Rainfall Possible in Puerto Rico and the Virgin Islands, the Upper Midwest, South Texas

Hurricane Erin may bring isolated flash and urban flooding, landslides or mudslides, and possible tropical storm conditions to Puerto Rico and the U.S. Virgin Islands this weekend. Scattered thunderstorms and heavy rainfall may bring areas of flooding this weekend over the Upper Midwest. A tropical disturbance will bring locally heavy rain and mainly urban flash flooding to far southern Texas. Read More >

LSR Summary

Environment

An upper-level shortwave trough moved across the mid-Mississippi and Ohio Valley during the evening hours on March 30th. A 35-40 kt southwesterly low-level jet provided sufficient shear for severe storms, while a warm and humid environment ahead of a cold front provided the necessary fuel.


Figure 1: 500 mb Heights and Winds at 8 PM EDT 03/30	Figure 2: 850 mb Heights and Winds at 8 PM EDT 03/30	Figure 3: Surface Temperatures, Dewpoints, and Mean Sea Level Pressure at 8 PM EDT 03/30

Surface-based instability between 1000-2000 J/kg ahead of the cold front provided ample fuel for thunderstorms. Moderate to strong low-to-mid level flow resulted in enough vertical wind shear for storms to become strong and severe. One key parameter was the 0-3 km bulk shear vector, which was oriented from west-southwest to east-northwest around 35 kt in the vicinity of the tornadic portion of the line. Where the line was oriented more north-south, this shear vector was more favorable for mesovortex genesis, which was between downtown Louisville and the Western Kentucky Parkway.

Note the corridor of significant tornado parameter values greater than 1 just ahead of the tornadic portion of the QLCS. LCL heights were not particularly low (between 750-1000 m), but were sufficient to sustain tornadic potential for a few hours on the evening of March 30th.
