Get ready for a breezy and warm Cinco de Mayo in Las Vegas as temperatures are expected to soar up to 90 degrees for the second time this week, according to the National Weather Service.

However, the 90s won't last long. An upper-level low pressure system will move into Idaho today with an associated cold front heading into central Nevada, the weather service said.

Breezy to windy conditions are expected this afternoon and evening, then temperatures will drop behind the front on Thursday and the high temperature will reach only about 80, forecasters said.

However, more above-normal temperatures are expected to return over the weekend, forecasters said.

McCarran International Airport recorded a high of 90 degrees just before 5 p.m. Tuesday, which was the first 90-degree day of the year. The last 90-degree day or higher was on Oct. 18, 2009, when McCarran recorded a temperature of 93 degrees, forecasters said.

At 4:56 a.m. today, the temperature at McCarran was 70 degrees. The normal low for today's date is 59 degrees. The record low was 40 degrees, set in 1950.

Around the valley just before 5 a.m., temperatures were 62 degrees at North Las Vegas Airport, 70 degrees at Nellis Air Force Base and 68 degrees at Henderson Executive Airport.

Temperatures in the valley were to rise today to 75 degrees by 9 a.m., to 83 degrees by noon and reach a high of 90 degrees by 4 p.m., forecasters said. The normal high for today's date is 84 degrees and the record high was 108 degrees, set in 1947.

Temperatures are expected to drop to 86 degrees by 6 p.m., to 81 degrees by 9 p.m. and to 75 degrees by midnight, forecasters said.

Thursday's morning low will be 65 degrees and Thursday's high will climb to 80 degrees, they said.
