Record highs could plague the Den­ver area again on Sun­day as tem­per­a­tures hov­er just under 100 degrees, the Nation­al Weath­er Ser­vice in Boul­der said.

Heavy smoke from the Cameron Peak fire, which forced more evac­u­a­tions Sat­ur­day night, could help keep the urban cor­ri­dor below 100 degrees. Den­ver saw a 101-degree high on Sat­ur­day that marked the city’s lat­est 100-degree day on record.

Tonight’s low will drop to around 58 degrees with winds gust­ing up to 26 mph. The high on Labor Day will be 92 degrees before a cold front moves in. Mon­day night has a 90% chance of rain, accord­ing to the weath­er ser­vice. The overnight tem­per­a­ture is expect­ed to drop dras­ti­cal­ly from 92 degrees on Mon­day to a low of 31 degrees.

Rain and snow are expect­ed on Tues­day as the high is pre­dict­ed to only reach 37 degrees. The weath­er ser­vice warns that some areas could see heavy snow with dam­age to vegetation.

Win­ter is com­ing! Heavy snow and record break­ing cold tem­per­a­tures Tues­day night. Are you pre­pared? #cowx pic.twitter.com/VodXMgVam8
