Strong high pressure will persist across the region reaching record strength by the middle of the week. Temperatures across the lower deserts will also increase into the triple digits starting Wednesday. Not only will all-time March temperatures be broken (and likely April as well), but also the earliest occurrence of 100 degrees in the Phoenix area.
High pressure will strengthen into record territory by the middle of the week, pushing lower desert highs above 100 degrees by Wednesday, then likely above 105 degrees Thursday and Friday. Daily records will likely be broken by nearly 10 degrees from Wednesday through next weekend. Excessive Heat Watches are in effect during the latter half of the week.
Phoenix and neighboring lower desert communities will almost certainly reach 100 degrees by the middle of next week. This would be the earliest occurrence of 100 degrees on record for the Phoenix area.
