TO: Wedding Thoughts

Well, you know this winter 2019-2020 has been extremely mild in Denver so this year is an anomaly from the normal. With that being said, NORMALLY it is still hot until about November 1st. Around November 1st, it starts getting cold and sometimes REALLY COLD when snowstorms begin to come through in November. In November, it is a mixture of mildly cold days and super cold days..

We’re predicting precipitation from April 1 to 7, then a sunny —er, clear— period (you will be looking up at night, of course). If the storm blows out early, you just might be in luck. Here’s hoping so!
