This morning's low temperature at El Paso was 1 and at Grand Canyon was -4. No other low temperatures were lower than mentioned in my last post.
Southwest Gas is reporting that customers in southeast Tucson and the eastern foothills are out of natural gas. They are advising customers to lower thermostats and limit hot water usage. The current temperature in Tucson (noon MST) is 29. Tomorrow morning's low is expected to again be around 18.
