After summer has stubbornly refused to give up just yet big changes in our local weather are headed our way beginning this weekend and continuing into next week. One of the main culprits behind this change will be a deep trough of low pressure dropping into the Desert Southwest late this weekend into early next week. A couple of cold fronts will work their way into the area with the strongest and coldest of these occurring Monday into Tuesday.
Today's run of the GFS computer forecast model indicates that we will drop down into the 60's and 70's as early as Monday afternoon and stay through Thursday. It also forecasts heavy rainfall from Friday night into late next week with local storm totals in the 1" to 3" range with some totals locally heavier.
Welcome to fall 2017. Additional details will become clearer this weekend into the first of next week but it appears that an extended period of much cooler and wetter weather is headed our way. Flash flooding may also become a concern.
