North winds to help Las Vegas air; dry spell at 178 days

Updated October 15, 2020 - 8:57 am

A northerly wind flow should allow Las Vegas skies to clear a bit over the next few days, according to the National Weather Service.

Smoke from California wildfires that has created moderate pollution for several weeks may abate as the weekend approaches.

“A north-northeasterly flow developing today and into tonight should keep the smoke pushing back and even offshore (to the Pacific Ocean) for the next couple of days,” weather service meteorologist Barry Pierce said.

Winds blowing back toward the valley are forecast for the weekend.

Above-average heat continues

The warm conditions will continue Thursday with a forecast high of 92, 10 degrees above normal.

The northerly flow may drop the highs into the upper 80s on Friday, but that won’t last long, Pierce said. “We’ll be back into the 90s for the weekend.”

Nearly half a year without rain

The record dry spell is in its 178th day Thursday. The last measurable rain at McCarran International Airport was April 20.

With no rain expected for at least a week, the valley will reach a full six months without official precipitation.

Elevated fire danger

The Colorado River Valley and Lake Mead National Recreation area are under a red flag warning Thursday.

“Winds along the river could reach gusts to 30 to 40 mph,” Pierce said. “It won’t take much if a spark starts something.”

Possible cooling

Months of above-average high temperatures could end, at least temporarily, in a little over a week.

“It’s a bit beyond the forecast period, but we are tracking conditions that could see some lows in the 50s or upper 40s with highs in the middle or upper 70s later next week,” Pierce said.
