The real trick for this Halloween is coming up with an accurate forecast. A storm will pull out of the Rockies today into the plains accompanied by gusty winds, some heavy snow on its cold side, and possibly severe thunderstorms in its warm sector. We will sit on the warm side of the storm through Halloween. The latest model guidance has temperatures falling into the 50s during prime trick or treat time. Hold on to your trick or treat bag. Winds could be gusting over 30 mph. Our RPM model has most of northern Illinois in a dry slot with most of the rain having already fallen earlier in the day.
Although we won’t break any records this Thursday there have been some notable records sent on Halloween in the past. The warmest Halloween on record occurred back in 1950 when the high hit 84°. A high of 31° back in 1873 marks the coldest Halloween on record. The Halloween of 1994 was the wettest when 2.26″ of rain fell.
