I got back yesterday from a 10-day trip to Las Vegas with Mrs Stodge - our fourth trip to Sin City and our third residing at the Palazzo (very comfortable).
Weather-wise, I thought mid-May would be a good time to visit but the prolonged spring in North America meant our first few days were marred by some unusually cool and windy conditions and on Wednesday May 18th, Vegas returned a maximum of just 67F, some 21F below normal and a new record low for that date. Indeed, the day ended with a couple of showers hitting the Strip.
The unusual conditions were caused by an LP moving off the Pacific into central California and then moving ESE more or less right over the Vegas valley. The LP dumped a foot of snow in the Sierra mountains and topped up the snow cover to higher elevations in Wyoming and Montana.
The strong SW'ly wind veered NW with the passage of the LP and Wednesday night was quite chilly with frost to higher elevations.
After that, HP moved in from the SW and temperatures began to recover peaking at a more seasonal 96F last Wednesday (the 25th). Night mimima recovered too but there still seemed a way to go to reach the triple digit temperatures expected at this time of the year. It was noticeable that humidity levels were higher than I've experienced in the past.
