'Twas the night before Christmas, when all through the state, twinkling stars foretold a sunny yuletide fate.

With Santa's arrival, valley inversions gave way, too; St. Nick won't gag on sooty air you could chew. So, no delays for delivering presents by wheezing reindeer this time, not with the air quality oh so sublime. The Utah Division of Air Quality is merry with the freshening air, awarding its "green" grade for the breathing out there. But enjoy clean air now; it's a short-lived gift, facing a high pressure system with no storms to lift.

Now Salt Lake, now Tooele, other northern Utah valleys, as well, will see how far overnight temperatures fell. Like Tuesday, on Wednesday the lows in the teens will be, with highs expected around 30 degrees. In the south, lows could plunge from the 30s to the teens at night, and by day could reach 50 degrees fahrenheit.

But up in the mountains, there's danger up there. The Utah Avalanche Center warning skiers to take care. Near Logan, "high" risks left for error little room, while in Ogden, Provo, Salt Lake and the Uintas, "considerable" risk did loom. Moderate slide risk held near Moab and Skyline; pay attention to cracks, "whomp" sounds and other warning signs.

For more forecasts for Utah this holiday week, point your browser to the Tribune's weather page (http://www.sltrib.com/weather), and you'll find what you seek.

So bundle up warm, embrace the Christmassy light, keep the joy of the season with all of your might.

And then you will also exclaim with that right jolly old elf, "Happy Christmas to all, and to all a good night!" From the Tribune to you, holiday wishes galore . . . and humble apologies to Clement Clarke Moore.
