Texas Winter Drought 2010-11 from La Niña

Back in July of 2009 I wrote about how one of the worst droughts in Texas was worsening.

Now it’s December, 2010, and we are staring down the barrel of another (winter) drought – one of the worst.

The U.S. Drought Monitor on Thursday indicated 85 percent of Texas is between abnormally dry and in extreme drought, compared to about 29 percent a year ago. Source: KBTX.com | Experts Fear Texas Heading Into Another Severe Drought

I appears to be the effects of La Niña.

La Niña causes mostly the opposite effects of El Niño. La Niña causes above average precipitation across the North Midwest, the Northern Rockies, Northern California, and in the Pacific Northwest’s southern and eastern regions. Meanwhile there is below average precipitation in the southwestern and southeastern states. Source: Wikipedia | El Niño-Southern Oscillation and NOAA.gov | ENSO Diagnostic Discussion

This certainly appears to be true. For the past week – 2 weeks before winter – the North Midwest (Minneapolis, Chicago, Detroit, Buffalo) has been buried by snow.

Winter’s Back

I know it’s not much sleet/ice build up, but it’s enough to keep 50,000+ Aggies home for last 2 days.

Winter Strikes

Yes that is ice. Winter hit last night in central Texas, and tempertures fell into the teens in Dallas and upper 20’s south of Waco.

It was cold enough and icy enough that work closed today. We usually get one “ice day” per year, but this is a little early in the season for it; winter doesn’t start for another 12 days.
