THE WEATHER OBSERVATIONS POSTED BELOW AREN'T CURRENT. THEY ARE FROM EARLIER IN THE DAY.
This is expected to be the hottest day of the week in the Valley of the Sun this afternoon.
Temperatures are expected to be near record high readings for today's date and it could do the same tomorrow.
Many locations are already above the century mark at this midday hour, so we'll see how hot it will get today.
There is a Heat Advisory in effect for the Phoenix metropolitan area until 8:00 PM Mountain Standard Time tonight.
Sky Harbor International Airport is close to setting a new all-time record for most 110°+ days in a single year.
Please note I'm only including yearly totals. I'll add the monthly breakdown once I figure out how to post them
where columns are aligned. The following information is directly from the National Weather Service.

2007 COULD SET RECORD FOR MOST 110°+ DAYS AT PHOENIX...
Through August 21st, there have been 27 days with a high temperature of 110° or greater at
Sky Harbor International Airport. This ties 1936, 1974, 1985 and 1989 as the 3rd most on record.
The most on record is 28, which occurred in 1979 and 2002. See Table 1 below for additional information.
However, summer 2007 is far from over. The latest observed 110° or greater temperature occurred
on September 15, 2000, meaning there is nearly a month-long window remaining when 110°+ temperatures
are climatologically possible. With high temperatures forecast to remain near 110° through the end of this week,
there is a high probability that 2007 will set the new record.
Have 110°+ days been increasing over the years? Yes, based on observed maximum temperatures for Phoenix
from 1896 through 2007. See Table 2 below for additional information. Possible reasons for this trend include
urbanization and regional/global climate change.
