Get ready for the coldest air of the season so far!
If you’ve been wondering “where the heck is the cool weather?”, you are definitely not alone! After a long stretch of warmer than usual days, we are seeing some definite signs that some much cooler weather is on the way. In fact, we are going to peak significantly in high temperatures late this week before plummeting this weekend. Here’s the current thinking on our next big system.
Heading into late Friday and Saturday morning, we’re tracking a stout low pressure system that will be completely changing our weather. Out in front of the system, a nice warm front will draw in a substantial amount of moisture and some much warmer air… so warm that temperatures this week will peak on Thursday with highs around 70. As of now, this cold front attached is set to move in on Friday which will bring our next chance of rain. Some showers and storms will pass through Friday afternoon and evening. However, the main impacts will be the extremely dry and cool air following the rain.
Thanks to a substantial trough, air from Central Canada will filter in by Saturday which will drop our afternoon highs about 20-30 degrees from what we’re expected to get this week. With such a tight temperature and pressure gradient passing through, the winds will really pick up steam. Wind speeds on Saturday will be sustained around 20-30 mph as well. With winds that strong, there’s going to a bite to the air with the wind chill. While actual highs will be in the mid 40s, it’s going to feel more like the mid 20s. Yikes!
Moline hasn’t had highs in the 40s since April 9th when the official high was 46. And if you think that’s going to be a shock to your system, just wait until early Sunday morning! With lows falling around the mid 20s, wind chill values are going to be dropping into the teens since winds will be steady at 10-20 mph.
The timing of when exactly the rain will arrive isn’t quite concrete yet since we’re still several days away; however, the arrival of the cold air is pretty set in stone!For those of us who haven’t been able to get into the holiday spirit just yet, Mother Nature will be sending a pretty obvious message this weekend that winter isn’t too far off.
