SIOUX CITY | Expect some creepy, cold temperatures in Siouxland, giving way to moderately menacing conditions later in the workweek, according to Janice Maldonado, a meteorologist with the National Weather Service in Sioux Falls.
"A northwest wind of 20-25 mph will keep things blustery in Sioux City," she said. "Winds gusting up to 40 mph will keep the high temperature from going above 40 degrees."
The overnight hours will also be cold when a northwest wind of 10-20 mph sends the temperature plummeting to around 21.
Halloween day will be positively frightful with Tuesday's high temp of 42.
Maldonado said trick-or-treaters may have to bundle up on Tuesday night, since it will be in the mid- to upper 30s in the early evening.
"Tuesday's nighttime low of 29 will make this Sioux City's 15th coldest Halloween in history," she warned.
Luckily, precipitation isn't in the forecast for Halloween or the remainder of the week.
However, a rebound of sorts begins on Wednesday.
"A southwest wind will send temps shooting up to the mid-50s," Maldonado said. "The daytime highs will be bouncing between the upper 40s and the mid-50s for the remainder of the workweek."
