Cold air advection was sure doing its thing today! High of just 48 after a low of 36. Rain, mixed with snow in some locations, amounted to just .03″, but some places like Vail and Catalina got a dusting of snow. Temperatures in the 40s much of the day felt colder with a bit of a breeze especially when the sun went behind a cloud. Hard Freeze Warning tonight as we have begun what may end up the longest streak below 50 degrees since 1971. Here are today’s numbers:
The cold front has moved through and now the cold air is moving in. Mike drinks yogurt and has your forecast in this morning’s Coffee and a Forecast:
The cold front roared through overnight and now the cold air will be settling in. A hard freeze is likely for the next three nights and so the National Weather Service has issued a Hard Freeze Warning. They’re on top of things like that. It is possible that the warning may have to be extended to include Tuesday, but there is plenty of time for that. Here are the specifics from the National Weather Service office in Tucson:

Mike explains what Graupel is which is timely since it fell on his deck yesterday. Hard Freeze Warning this morning and early morning tomorrow too but a slow warming trend will continue through the weekend. Another storm early next week? Mike talks about that possibility and shows us snow and cold temperatures in Texas, New Mexico and Missouri in this morning’s Coffee and a Forecast.
COLD this morning. Not much warmer this afternoon. COLDER tomorrow morning. A little warmer tomorrow afternoon, but still chilly. COLD again Wednesday morning and a little warmer by afternoon. The slow warming trend continues through the weekend. Enjoy Winter in Tucson!
At least for this stretch of really cold weather. I imagine we’ll have another Hard Freeze Warning again sometime.

Still, the all-time record low for February was 17 set February 7, 1899 and the forecast is for a low of 15!

Already a record cold start to a record cold day in Tucson. Snow and freezing rain possible today and tonight for places like Houston and Corpus Christi. Mike has details on this amazing cold outbreak.
The dewpoint has plunged and overnight lows are going down with it. Another surge of cold air is heading this way to reinforce the cold air in place. With the drier air, we actually got colder last night than expected. Tucson got down to 25 officially this morning. Gusty winds should relax overnight in the valley’s of southeastern Arizona allowing temperatures to plummet even more tonight. The National Weather Service has already issued a Hard Freeze Warning for tonight and tomorrow night and now they have dropped the expected lows for both overnight periods. The revisions are below. If this comes true, Tucson will set two record lows, both in the upper teens! Tomorrow’s high is now predicted to only be 38. If that comes true it will be second coldest high temperature ever in the 118 years they have been keeping records in Tucson. The coldest was 37 on February 6, 1899! Amazing.
