Storm 10/20/09 Recap

Strong storms moved into the Borderland yesterday (10/20), bringing rain, wind, and reports of hail. The above photo was taken by Steve Green, who captured some brilliant lightning in Northeast El Paso. Our storm system was a unique combo of a strong upper level trough and a tap of sub-tropical moisture in the Borderland. As the trough moved east, it spun up an surface low pressure system that, as of this writing, is just now moving out of New Mexico. Along with a changing of wind speeds with height (speed shear) and cool dry air pushing in behind our storm, the atmosphere was able to spin up a line of strong thunderstorms through the region. Official rain totals were only about .04" of precipitation at El Paso International Airport. Here are some other totals: Santa Teresa (NWS office): .34" Las Cruces Airport: .11" Turth or Consequences: .25" Ruidoso Airport: .31" Deming: .14" There were reports of heavy rain, wind gusts near 60 miles per hour, and small hail. Most of the storms hit the western part of the Borderland early in the afternoon with the bulk of the rain falling between 4 PM and 9 PM in El Paso & Las Cruces. Behind this storm comes a much more quiet weather pattern. Aside from an unnoticeable upper trough pulling through here at the end of the week, we will see warming temperatures with little to no chance for rain through next week.
