Getting Ready for
September has some of the best weather Colorado has to offer. Many days feature plenty of sunshine with little or no shower activity. Temperatures are generally in the 80s with overnight lows getting a bit on the chilly side dropping into the 40s. It is not unusual to have a frost or freeze before the end of the month, but typically the first frost or freeze waits until October.
What September is the perfect time to get ready for the coming cold and snow of winter. A good time to get the car or truck, not to mention the home ready for heating season. Last year was bad enough with the energy bill, sticker shock. With energy even higher this year you can bet those bills will be even higher this year!
Even though we enjoy all this nice warm weather, it is a good idea to start winterizing the car or truck. Have the anti-freeze check, have your tires checked, put the snow tires on. Yes I know sounds early, but it does snow in September! Check your supply of window deicer. If you make long trips during the winter months, especially in the high country, put together a list of things to store in the trunk, such as a small shovel, flashlight, and small survival kit. This is also a good month to have the oil changed and have a tune up. You really donít want to have a breakdown in the middle of a snowstorm. Think about putting a 50-75 pound bag of sand in the trunk. Not only does it add weight and extra traction to the rear wheels, but should you become stuck, you have sand with you to get some extra traction.
Home heating is a big one for many people and there are many things you can do to reduce the amount of energy you use. Again with all the nice weather in September, itís a good time to check the caulking around the windows, remove old and worn caulking and install new. Check weather stripping around doors and windows, if it is worn replace it. If it has been a while since you checked the insulation in the attic, itís more than time to check it. Perhaps another couple inches of insulation will help shave some dollars off the heating bill. Also this is a good time to check the furnace. Make sure the filters are clean. Dirty filters cut down on the efficiency of your heating system. If it has been more than 2-3 years since a professional has checked your furnace perhaps you should consider bringing one in. He can check the furnace to make sure it is operating at peak efficiency and check your duck work for leaks.
Windows leak more heat to the outside than any other part of the house. If some are single pane, if the budget allows replace them with double pane glass. Window coverings can play an important role in keeping the heat in the house especially on north facing windows. Insulated drapes or window coverings can significantly reduce the amount of heat that passes through a window. Even small things can help with household heating. Open drapes on south and east facing windows to allow the sun to help heat the inside, while keeping sunless windows covered.
There are many more things that can be done to save money on the gas or electric bill, the important thing is to get started on them now, before the cold weather hits in October and November.

Little change in drought conditions across most of Colorado, with few areas of drought remaining..
The map below shows forecasted temperature deviances for September 2005. As can be seen, normal temperatures are expected for Colorado for September 2005.
The map below shows forecasted precipitation deviances for September 2005. Normal or near normal precipitation is expected for Colorado for September 2005.
As can be seen in the below map, most of the state has come out of the widespread drought conditions of a year ago.
August 2005 marked the 2nd month in a row with below normal precipitation. (However, this statistic is very misleading, with most areas across Metro Denver seeing well above average precipitation for August, and the "official" rain gauge at DIA being very unrepresentative and poorly located). So far this years total through August 31st is 9.74 inches. This compares with 11.33 inches through the same time frame last year. There were 8 days with measurable rainfall. Four of the measurable days occurred with thunderstorms. There were also 6 other thunderstorm days that produced trace amounts or less. No severe weather or hail was observed at DIA.
Nothing much to note about temperatures as the month finished near normal. The average temperature was 71.6 degrees which is only 0.1 below normal. The mercury readings ranged from a high of 97 degrees to a low of 50 degrees. Two records were set in August 2005 and both were low maximum temperature records. 61 degrees on the 4th broke the old record of 66 degrees set in 1936. Then on the 13th, a 63 degree high temperature was a new record low maximum, breaking the old record of 69 degrees set in 1938. There were 13 days with readings 90 or above, with the normal being 9 and for the year there have be 46 90 degree days which is 16 above the normal of 30.
September is normally a sunny, pleasant month in Denver with the highest monthly percentage of sunshine for the year. The general weather pattern features fall-like weather consisting of bright sunny days and clear cool nights.
Summer can linger as late as the end of the month. On September 30th 1980 a record was set when the temperatures reached a high of 90 degrees. In fact, the first 20 days of September all have record highs in the 90s. 97 degrees stands as the hottest temperature ever recorded during September and that occurred 4 different times, with the last 2 occurrences recorded on September 1st and 4th in 1995. Thunderstorms are still around in September, however, they are less frequent and severe storms are rare.
Winter can also sneak in during September. The earliest measurable snowfall on record occurred on September 3rd in 1961 when 4 inches of snow fell at the old Stapleton Airport and the temperature dropped to 33 degrees. The earliest freeze in Denver was September 8th in 1962 with a record low of 31 degrees. A real taste of early winter came in 1985 when on the 29th, 9 inches of snow fell on the city and the mercury dropped to a low of 17 degrees after only reaching a high for the day of 29 degrees. Both of those temperatures were records for the date. Although we can see snow during the month of September there have been 79 Septembersí since 1882 that have reported no snow.
