TUCSON – Today marked the 12th consecutive day the City of Tucson has seen below average temperatures. Out of the 17 days so far this month, 14 have been below average.
If you compare the first 17 days of October this year to last year, well there is simply no comparison. This year’s average October temperature is more than 10 degrees cooler.
We’re off to the coldest start to October since 1982 – when through the first 17 days the average temperature was 67.4 degrees.
Many years we talk about the latest 100 degree day occurring in October: well forget about that. The highest temperature we’ve recorded this month has been a “cool” 89 degrees.
Don’t look now but warmer weather is in the forecast, but even highs on the warmest days look to only be a degree or two above average.
With two weeks still remaining of the month, it would take a major heat wave to put the entire month of October above average…and that isn’t in the forecast. This means October 2018 will be the first below average month we’ve seen since September of 2016.
TUCSON – Rain overspread much of metro Tucson – AGAIN – tonight and more rain is in the forecast tonight through Tuesday. And oh, don’t look now, but more rain is possible this weekend and even into next week if we can tap into Tropical Storm Tara.
Okay back to the big chill: the first 15 days of October have been colder than the first 15 days of November last year. (How is that even possible?)
So halfway through the month, we now rank as the 19th coldest October since records have been kept (1894). What’s more staggering is if you take out most of the colder October’s which occurred at the beginning of the 20th century, this October ranks as the 4th coldest since 1959! Only the first 15 days of October in 1966, 1970, and 1982 were colder!
And by the way, it’s currently snowing on top of Mt. Graham. See the image below.
TUCSON – Record rain (0.76″) on Wednesday put the monsoon total in Tucson at 7.01″. This is the fifth year in-a-row that the City of Tucson has exceeded its monsoon average of 6.08″.
In addition, for the first time since the early 1980s, Tucson has picked up over 7.00″ of rain in three consecutive years.
Drought conditions remain across much of the State of Arizona and according to chief Meteorologist Matt Brode, this is in part due to fewer Winter storms over the past several years.
Abundant monsoon rain has the City of Tucson in a small yearly surplus, but we’ll need to pick up about another 3″ of rain through the end of the year to match our annual average of almost 12″ of rain.
TUCSON – We often ponder in the weather center when to use the term ‘hot’ to describe our weather. We all agree that anytime we hit 100 or more, we use the term hot.
If it were 88 in the summer, naturally we would say it’s ‘cool’. But I’m calling our projected high of 88 degrees tomorrow ‘hot’. Why? Because it’s winter!
Strong high pressure continues to build, and because we hit 86 today in Tucson, I think 88 is easily accomplished tomorrow. BTW: this would break the record of 85 – set back in 1957.
So here’s the scoop. 88 on Saturday, 86 on Sunday (another record), and then by Monday I’m forecasting 83 -tying the record.
Bottom line: a lot of events are going on this weekend…Rodeo, Match Play, Gem Show…so please stay hydrated and wear the sunscreen.
Somewhat cooler weather arrives next week.
Happy Valentine’s Day and Happy Birthday to Arizona – which is now 102. At least the temperature is not 102; yet!
