(MCT) — Temperatures are expected to be above normal for Halloween this year, but there's also rain in the forecast.

WGN-TV meteorologist Tom Skilling is predicting showers for Thursday, with possible thunderstorms; the rain should last into the evening. He also forecasts a high temperature in the low 60s on Thursday, with a low in the high 40s.

Those temperatures are above normal for Halloween in Chicago, according to the National Weather Service. Based on 141 years of readings, the normal high for Halloween is 56 degrees, with most Halloween temperatures falling between 50 and 59. The normal low is 39 degrees, with most falling between 40 and 49 degrees.

The warmest high on Halloween was 84 degrees in 1950, the only time in recorded history that the high was in the 80s. The coldest temperature recorded on a Halloween was 31 in 1873.

There has been no measurable precipitation on 51 per cent of the Halloweens since 1873, according to the agency. The most rain to fall on the day was 2.26 inches in 1994.

There's been snowfall on 5 Halloweens, the agency said, but never a measurable amount. The last time it snowed here on that day was in 1993.
