Dew points to fall, but hope for a week in the future

Starting today, the dew point temperature is going to fall. By this weekend, our dew point temperature will be in the 20s.

Is the monsoon season over?

Looking out 2 weeks, you might think so. Today is the last day in the current forecasts and outlooks when Northern Arizona can strongly expect rain.

Finally, the wind outlook shows the strength dropping through this weekend and swinging around to the south to southeast by early next week. [...]

Yesterday, most of Arizona moved into the above average precipitation zone for the 8-14 day period.  This period starts on July 2. This is very positive news of a wet and timely start to the monsoon season.   On [...]

The good news is that most of Northern Arizona remains in the above average precipitation zone for the summer. Still, I don’t believe El Niño is the link. There are a combination of factors. The Climate Prediction Center issued a new 3-month outlook last week. The bad news is that the winds may not leave [...]
