Snow plows in July?? (NM storm dumps over a foot of hail clogging roads)

July 12, 2013

hail piles up city street santa rosa fdThe Weather Channel reports a lone thunderstorm dumped over a foot of hail in the town of Santa Rosa, New Mexico last Wednesday evening (July 3, 2013), leaving a surreal sight the day before the Fourth of July.

Photos from the Santa Rosa Fire Department showed snow plows clearing city streets clogged with accumulated hail drifts. According to the National Weather Service in Albuquerque, hail up to golfball size pelted the city around 6:00 p.m. MDT.

Although this sounds strange, accumulating hail is not uncommon in the High Plains according to TWC. Northeast New Mexico sits in what meteorologists call “Hail Alley“, a swath from southeast Wyoming and northeast Colorado to northeast New Mexico and the Texas Panhandle, where large hail falls on average at least three days a year.

And, considering much of the country is sweltering with intense heat, we thought this might be a “cool” set of Friday Fotos to share.

TWC writes some other unusual hailstorm events include:

  • April 11, 2012 (Dumas, TX): The volume of both hail and rain overwhelmed a shallow gully, or draw, near the U.S. 287 bridge, piling the water and ice mass into massive drifts up to 10 feet high, trapping vehicles and forcing closure of the road for 12 hours.
  • August 14, 2004 (Clayton, NM): Up to 16-foot hail glaciers. Some ice cover lasted almost a month…even in late summer!
  • May 9, 1994 (Dalhart, TX): Up to three-foot hail drifts shutdown U.S. 385 for almost one month

We also found a short video by TWC’s Dr Greg Forbes explaining how thunderstorms produce hail.

Stay safe and cool out there .. and have a great weekend! 🙂 j & B
