PHOENIX -- The ridge of high pressure that has been giving us all the warm and dry weather continues to break down and weaken. In its place, an area of low pressure is forecast to move into the western third of the country later this week and for the weekend. That's going to bring us a big change in temperatures. Most areas of the state will see temps drop 10 to 15 degrees over a couple of days.
In the Valley, the warmest day this week will be Thursday. We're expecting a high of 80. Then the cooler temps come. Highs will only be around 70 for Saturday and Sunday and in the upper 60s next week. However, no rain is forecast for metro Phoenix so our dry streak will continue.
Flagstaff has a slight chance to see some light snow this weekend. Those chances pick up just a little bit early next week. Flagstaff has had 37 days in a row without snow. That's pretty unusual for that location.
