... Record high temperature forecast for Phoenix Sky Harbor Tuesday...

Increasing southwesterly flow ahead of an advancing low pressure
system will bring unusually warm weather to the Sonoran Desert
Tuesday... with record highs possible in some areas. Temperatures
will begin to cool Wednesday as the low pressure system moves
closer... with much cooler though near-normal temperatures expected
late in the week and into the weekend.

The record high temperature for Tuesday... the 10th of November... at
Phoenix Sky Harbor is 90 degrees set in 1989. This record is expected
to be broken with a high of 91 degrees forecast.

The latest in the year that 90 degrees has been reached at Phoenix
Sky Harbor is the 15th of November and that occurred in 1999. The
average last 90 degree day in Phoenix... from 1979 to 2008... is
October 28. The earliest in the year that 90 degrees has been
reached is the 24th of February. That record was set way back in
1904 and tied 82 years later in 1986. The average first 90 degree
day is April 1... based on 1979 to 2008 data. This means that you can
usually expect five months... and at least 3 months... with
temperatures staying below 90 degrees in Phoenix.

Note that meteorologically and climatologically... winter in the
northern hemisphere is defined as the three months of December...
January... and February. In Phoenix... the coolest three month
