PHOENIX -- Shower and thunderstorm chances are on the rise as a low pressure system and deeper moisture moves into the region from the east Monday.
The primary threats associated with any developing storms will be gusty winds, blowing dust, localized heavy rainfall possibly leading to flash flooding of dry areas, and dangerous lightning. Rain chances are in the forecast each afternoon all the way through the end of the week and into the weekend.
Storm chances for the Valley Monday are starting off low this morning. From 11 a.m. to 4 p.m., the Valley has a 30 percent chance. That chance grows to 50 percent after 4 p.m.
We're expecting highs today in the Valley to top out around 100 degrees. Yesterday's high at Sky Harbor was 110. We'll keep the cool temperatures and high humidity around for at least the next 7 days.
The current low pressure system is further east and south than previously anticipated and this will limit the threat for severe thunderstorms in the mountains. There is still enough moisture present across northern Arizona, so heavy rain and flash flooding will be possible with stronger storms. This threat stretches from the Grand Canyon to Payson.
