This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid. ![]() Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.Īll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition, by Jean Meeus.Īll other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis. To get a sense of how much these sources agree with each other, you can view a comparison of Phoenix and the stations that contribute to our estimates of its temperature history and climate.

There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Phoenix.įor each station, the records are corrected for the elevation difference between that station and Phoenix according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. Erinanne Saffell, Arizona’s state climatologist.This report illustrates the typical weather in Phoenix, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016. Smith said by next Monday, the high was expected to be 108 (42.2 C).īefore this year, the longest stretch of days where temperatures reached at least 110 degrees was 18, in 1974, said Dr. ![]() “We are expecting to see the highs fall through this weekend, with chances for monsoon rains rising to 40-50%.” “It seems unlikely we’ll see over 110 every day through the end of the month,” said meteorologist Isaac Smith, of the National Weather Service in Phoenix. The record was likely to grow Wednesday, with a high of 119 degrees (48.3 C) expected.Ī bit of relief might be on the horizon, though, after this week. Phoenix this month shattered its record for consecutive days in which the temperature reached at least 110 degrees Fahrenheit (43.3 Celsius), standing at 26 days and counting as of Tuesday, when the forecast called for a high of 118 (47.8 C). PHOENIX (AP) - Longtime Phoenix residents know that sweltering Julys are to be expected, but no one could have predicted the brutal heat wave that has enveloped the country’s fifth largest city this summer. ![]()
