MORNING: Wake-up temperatures in the upper 40s and low 50s early, then 60s by 9 a.m.
AFTERNOON: Sunny with record-setting highs in the low 70s.
EVENING: A drop through the 60s into the 50s after 8 p.m.
TONIGHT: Lows near 50 late. Still calm and clear.
A record-setting 73 today in Las Vegas (prior record is 72 from 1939).
Friday remains very mild, near 72, which is just shy of the record of 74 from 1958.

Nighttime lows in the upper 40s to near 50 around Las Vegas are expected for the foreseeable future. That’s chilly, but nearly 10 above-average for December.
Highs in the upper 60s to near 70 will be the rule this weekend and early next week. Upper 60s will hold the rest of next week.
A weak system may bring a few showers on Monday, December 22nd and Tuesday, December 23rd, but the chance is only 10% as we see it now. Christmas Eve and Christmas Day look partly cloudy, dry, and a little cooler with highs in the low 60s and nighttime lows in the low 40s.
