SYNOPSIS

Expect very warm temperatures to develop over the next several days. Temperatures by early next week may be the highest ever seen in March, prepare for an early look at summer.

DISCUSSION

Moisture that was trapped under a subsidence inversion yesterday should erode today as strong high pressure builds over the region. The next 7-10 days will feature increasing temperatures and little in the way of weather, aside from some minor breezes and high clouds over the weekend.

Temperatures by this time next week are likely to be the highest ever seen in March across the southwest. Prepare for an early look at summer.
