UPDATE OCT. 31: We've dropped to 29 degrees at the Henderson Executive Airport this morning, and it's 30 degrees at Nellis Air Force Base. These are the first sub-freezing temperatures in the Las Vegas valley since late February. The mercury at McCarran has "only" dipped to the mid-30s. The Freeze Warning is scheduled to expire at 10:00 a.m.

Watch the forecast:

Trick-or-treat temperatures: We'll be in the upper 50s as the sun sets just before 6:00 p.m. Readings around the valley will fall through the 50s into the upper 40s as the evening wears on. Summerlin and neighborhoods in West Henderson will fall to the 40s by 7:00 p.m. The rest of Las Vegas should dip below the 50 degree mark around 9:00 p.m. Please consider wearing layers underneath your costume, or a coat on top, as this will be one of the chilliest Halloween evenings in several years. At least the winds will be on the light side at 5 mph or less.

LAS VEGAS (KTNV) -- The gusty winds Tuesday evening delivered wake-up temperatures in the mid 30s across the entire Las Vegas valley this Wednesday morning.

Highs will struggle to make it to the mid 50s Wednesday afternoon. That's the coolest daytime high we've seen since February. Breezes will gust to 25 mph this morning and this afternoon before fizzling this evening.

A Freeze Warning is in place for the Las Vegas Valley from midnight through 10:00 a.m. Thursday as readings drop near the freezing mark. The average first freeze at McCarran is November 29th. The earliest first freeze on record is October 21st, 1949.

After a cold start on Halloween, it will climb to the low 60s in the afternoon. Trick-or-treat temperatures in the 50s will dip to the upper 40s after 8:00 p.m. but at least the wind will be calm. A warming trend will begin as we make our way toward the weekend with highs in the upper 60s Friday and the low 70s Saturday and Sunday.
