Heads up if you are traveling for Christmas to California, where dangerous flooding is expected! #cawx

Temperatures continue to run well above normal as highs across the lower deserts topped out in the upper 70s to lower 80s today. Phoenix set a new record high, breaking the previous record from 1917 by 4 degrees. #azwx

For the second day in a row, a record high temperature has been set at Phoenix Sky Harbor Airport. As of 1:57 pm MST, the site recorded a temperature of 80°F. The previous record for today's date was 79°F set in 1917. #azwx

Here are some potential rainfall totals through 5 AM MST Wednesday (low/median/high end). Notice how totals upwards of 0.25-0.50" will be relatively isolated and confined to foothills and higher terrain north of the Phoenix Metro Area (mainly Yavapai County).

Latest high-resolution models now capture most of the "first round" of precipitation with the incoming system. Here is a loop of potential future radar Tue afternoon - 5 AM MST Wed. Rain will be light and fall through dry air, so not all of it will reach the ground. #azwx #cawx

Morning low temperatures were generally a couple degrees warmer than yesterday's, with values ranging from the middle 40s to middle 50s across the lower deserts. Once again, anticipate a mix of high clouds and sun today, with highs challenging records in some places. #azwx #cawx

Dry conditions continue today, but unsettled weather is expected for the Christmas holiday, with multiple rounds of rain likely. Expect regional travel impacts, especially if heading to or from southern CA, where heavy precipitation is forecast. #azwx #cawx

High temperatures today were around 10°F to 15°F above the daily normals, including 81 °F at Sky Harbor airport breaking the daily record set just last year (2024). Look for nearly the same tomorrow before cooler readings & unsettled weather arrive later in the week. #azwx #cawx

A new high temperature record has been set at Phoenix Sky Harbor Airport for today's date. As of 1:50 pm MST, a temperature of 80°F was recorded at the site. The previous record was 79°F, which was set last year (2024). #azwx

Happy winter solstice & first day of astronomical winter! Morning low temperatures once again ranged from the middle 40s to lower 50s across the lower deserts. Afternoon highs will near 80°F for the typically warmer locales under a mix of sun and high clouds. #azwx #cawx

Another day, another unseasonably warm day with afternoon highs across most of the lower desert locations approaching 80 degrees. There is a high likelihood (80% chance) of Phoenix breaking a daily record high, which is 79 degrees set just last year. #azwx #cawx

It was a beautiful first half of the weekend with lower desert highs temperatures ranging in the middle 70s to lower 80s. The warm trend will continue over the next few days ahead of a slight cooldown by the middle of next week. #azwx #cawx

A pattern change will occur during the middle of the upcoming week. Persistent high pressure finally shifts eastward as a strong low sets up just off the West Coast. Abundant moisture streaming inland will increase rain chances by late Tue/Christmas Eve. Stay tuned... #azwx #cawx

Morning lows were generally in the mid-to-upper 40s across the lower deserts this morning, with a handful of more urban locations showing readings around 50°F. Look for a mix of high clouds and sun today, with afternoon highs in the mid-to-upper 70s. #azwx #cawx

If planning to do hiking this weekend, the weather is expected to be ideal with dry conditions, light winds, and afternoon high temperatures in the 70s. #azwx

Despite an increase in high clouds, high temperatures this afternoon were again 10°F to 15°F above the daily normals, but just short of daily records. Nearly identical conditions will persist through the weekend. #azwx #cawx

Well above normal high temps will continue through early next week, with potential for more daily records. El Centro is forecast to break their record high this afternoon and tie on Monday, while Phoenix has high probabilities of tying or breaking Sunday & Monday. #azwx #cawx
