This past week has brought a much more normal pattern in terms of weather than we've experienced this fall. This week although still warm climatologically speaking, still felt like the first burst of fall air with multiple days of cool rain as well. Shifting our focus to the weekend and beyond, we look to remain in a comfortable pattern temperature wise to start but our first big cool down for the season looks to arrive later this week!
After a quick warmup through the beginning of the week a "dome" of cold air will be funneled down into the majority of the United States due to a large low-pressure system that will be overhead here Wednesday. This will be the coolest air we've felt this fall as temperatures are expected to drop into the low 40's and even low 30's into the overnight hours.
As of now some form of precipitation looks likely at least Wednesday when the low-pressure system is overhead, but the form of precipitation remains in question. Currently, surface temperatures look to remain just above freezing Wednesday night, but a drop of a few degrees will increase our chance at some form of wintry precipitation. Those chances remain lower though as of now but for locations further east their first snowfall may be almost guaranteed as those areas will have cooler surface temperatures and just a bit more moisture.
Regardless be on the lookout Wednesday as even with warmer surface temperatures a heavier rain event looks to take place with possible showers going into Thursday.
Beyond that though, temperatures look to remain cool through the weekend as cold polar air from Canada is expected to continue to be funneled into the Midwest. Say goodbye to the sun this week though as cloud cover looks to stay consistent this week!
