Downright Toasty and Drrrryyyy!!!
If the first week of June is any indication we are in for a hot and very dry summer along the Front Range. As of May 31st we have receive only 2.60 inches of rain over that 5 month period. Our spring snows failed to materialize and now we been seeing nothing, but dry thunderstorms. Normal by this time of year is 6.53 inches. In the scheme of things 6.53 inches is really not that much so when you are 3.93 inches below normal it makes a big difference. If it were not for a thunderstorm that produced 0.44 inches of rain over DIA on the last day of May we would actually be drier than we were in 2003 when Denver had its driest year ever. Our one saving grace has been the large amounts of snow that fell in the northern and central mountains that filled many of the reservoirs that we use along the Front Range. Had those snows missed the high country, we would be in for more restrictions on water use. Our latest 30 day forecasts which cover the month of June indicate an above normal month for temperatures and a below normal month for precipitation, not what we really want to see. With all the hot and dry weather, fire danger along most of the Front Range is very high and climbing. Now of course we are going to see numerous articles in the months to come blaming global warming for our dry conditions and for the heat. The media seems convinced that global warming is a fore gone conclusion and that we should be buy beach front property right here in Colorado, because the oceans will be rising and inundating our coastal areas. Yes overall (globally) average temperatures have risen slightly less than one degree in the past 60 years. But, as I’ve said numerous time in previous articles, by its’ very nature our climate constantly changes. It is either warming or cooling in cycles that can last decades or even centuries. When I was in college in the 70s, the major concern at that time was that we were going into another ‘Ice Age’ and that something had to be done before we were hip deep in snow!! So much for that theory!! There was an interesting article in the Denver Post on Monday June 5th. In that article Bill Gray the hurricane forecaster at Colorado State University calls this global warming hysteria a “hoax”. Gray acknowledges that we have had some warming in the past 30 years. “And humans might have caused a very slight amount of this warming. But this warming trend is not going to keep going. My belief is that three, four years from now, the globe will start to cool again, as it did in the 40s and middle 70s.” So have we warmed up?? Yes but only slightly!! Is this warming to blame for hot and dry weather here in Colorado?? NO!! If you want to blame something for how dry it is in eastern Colorado, blame it on the Rocky Mountains! Is this warming to blame for all the hurricanes last season?? NO! Oh and by the way Bill Gray is predicting another active hurricane season! Not because of global warming, but because we are in an active hurricane cycle. Printing Newsletters Now Possible We have received many requests over the years of how to print this newsletter.

June Preview June is severe weather month for Denver. Severe thunderstorms and tornadoes are notorious in Denver and across eastern Colorado during June. Over 40 percent of the tornadoes that occur in Colorado are observed during June. June tornadoes and severe thunderstorms have caused extensive property damage in and near the Denver metro area in years past. Some of the more notable tornadoes occurred in: Thornton on June 3, 1981, southeast Denver and Aurora on June 8, 1986 and east Denver on June 13, 1984. In addition, on June 13, 1984 powerful thunderstorms dumped large hail, making it one of the worst and costliest hail storms in Denver history. During June 2001, a major hail storm moved across Denver International Airport on the 20th, dropping hailstones as big as two inches in diameter. Even though there are frequent tornado occurrences in eastern Colorado during June, there has not been a tornado related death since 1960. However, there have been several deaths attributed to lightning during June. Cool weather can still occur in early June. The latest freeze on record in Denver occurred on June 2, 1951 when the mercury dropped to 30 degrees. This is also the record low temperature for June. Snow has been reported in the city as late as June 11th when in 1947 a trace of snow was reported. The wettest June was in 1882 when 4.96 inches of rain fell and the driest June was 1890 with only a trace of precipitation recorded. The maximum 24 hour precipitation was 3.16 inches on June 11, 1970. By the end of June, the mercury has been known to climb to 100 degrees or higher. The record high temperature for June is 104 degrees set on June 26th 1994.

The warmest June occurred in 1994 with an average temperature of 73.5 degrees. The coldest June was 60.6 degrees in 1967. The 30 day outlook for this June calls for above normal temperatures. As for moisture the models call for below normal precipitation for the month. If the first week of the month is any indication we could very week see our 8th month in a row of below normal precipitation.
