We are still 5-7 days away from a storm system potentially impacting the Midwest and here in Illinois but over the last few days, model guidance has continued to show a storm system in some fashion traversing through the Midwest in the Tuesday-Wednesday time frame of next week. As mentioned we are still a ways away from this but there is the potential for wintry weather with this, including the threat of accumulating snow. Remember though **nothing is set in stone and we are simply mentioning the potential is there**...........Some initial thoughts and information follow below...
By Sunday morning, model guidance has our system of interest coming ashore California with sights set on the Four Corners region by early next week. What happens after that remains in question with details a long ways from being sorted out but there is decent agreement right now on some sort of weather system entering the western U.S. the latter half of this weekend.
By Monday evening next week, model guidance is suggesting there will be a frontal boundary laid out from southwest to northeast from the southern plains into the Midwest. Along this front, an area of several areas of low pressure or smaller weather systems could move along this front, producing swaths of precipitation (potentially in the form of accumulating snow) across the Midwest during the early to middle portion of next week. As you can see on the image below, every "L" on the map is one possible location of an area of low pressure. This is called an ensemble forecast and is used to show the spread of uncertainty at this range.
Outside of outlying an area that could see wintry weather, including accumulating snow next week, we will not go into any further details in this article and continue to watch model guidance come in over the coming days. Stay tuned though for updates, especially if the potential begins to increase for something substantial across the region next week.
