One Minor Storm Closes Out September 2013, Our Wettest Ever

Mountain residents were happy to see September come to an end. Our rainfall total for the month was 8.45 inches, far less that the 15-21 inch total for the central part of Boulder County, but still substantial. It was over twice our wettest September….1996, at 3.71 inches; and nearly five times our normal precipitation of 1.70 inches. Usually we welcome wet months but not this time. With all the tropical air we ended up 2.5 degrees above normal with an average high of 65F and an average low of 45F. It was windier than normal with 5 days over 40 mph….2 days is normal. The final week of September began with Friday’s vigorous cold front and a rain band. The rapid motion didn’t allow for large accumulations. My total was 0.29. One exciting observation was barely measurable snow totaling 0.1 inches….officially the first snow of the year. We had a couple of subfreezing days following the front. Gusty winds moved in with a peak gusts of 47 mph on Saturday and Sunday.

Interesting weather on tap for the foothills this week… comes winter! We will see a storm on Thursday and Friday similar to last week except it is stronger and colder….thus a good chance of snow. Several inches will be possible…probably 4 to 6 inches. Through the weekend we’ll see a warm up with gusty winds. By Tuesday another front will move through and will make snow likely on Wednesday. Temperatures will fall into the 20s and upper teens so take precaution if you have outdoor plants.
