Monsoon arrival in the San Juans?


The strong ridge of high pressure that has been parked over the intermountain west since June will remain to our west through tomorrow then will move east of the continental divide Monday allowing southerly flow to develop.  This will draw sub-tropical moisture northward bringing a better chance of rains to develop over mountainous terrain and possibly the higher valleys.  RH will increase during the week with cooling temperatures.  This could be the beginning of the monsoon season …  the latest 8-14 day forecast is typical mid/late-July with warm temperatures and increasing chance of active weather (showers and thunderstorms).
