Climate Prediction Center 8-14 Day Temp Outlook

Strong high pressure will build across the region, reaching record strength next week. Temperatures across the lower deserts will increase into the triple digits as we head into the middle to end of next week. Not only will all-time record March, and potentially even April, temperatures likely be broken but also the earliest occurrence of 100 degrees in Phoenix.

Strong high pressure will take over by this weekend into early next week, pushing highs into the upper 90s to low 100s which is record territory.

Phoenix has a high probability of reaching 100 degrees by the middle of next week. This would be the earliest occurrence of 100 degrees on record for the Phoenix area.

The Climate Prediction Center's 8-14 day temperature outlook shows a high likelihood (80-100% chance) of above normal temperatures continuing for our area through the end of March.
