ROCKFORD (WREX) – Saturday has featured a mix of sun and clouds, but changes are in store for Northern Illinois to wrap up the weekend.
Before I get into the forecast details, hopefully my Game of Thrones fans were able to appreciate the title of this post. I have seen exactly one episode, but I digress.
Clouds have been a prominent feature of this Saturday afternoon’s sky. It has been dry, but it has also been blustery. Winds out of the northwest have continued to gust to close to 30 MPH at times through the day. Those breezy conditions continue at times through the evening, so if you have plans to hit the town later tonight, keep that in mind. Grabbing a light jacket may not be a bad idea, especially since temperatures will fall into the 30’s by midnight.
Temperatures tonight will fall into the 30’s with dry conditions holding until about midnight. A vigorous area of low pressure anchored over Texas. It has brought a lot of severe weather, including tornadoes, to parts of the Deep South. This same area of disturbed weather will lift northeast into the Midwest. The severe weather threat remains placed over the Southeast, but the northern fringe of this storm could bring a dose of wintry precipitation.
“How far north?” you may be asking. That is the million dollar question. Model guidance suggest many in the Stateline could see a mix of rain and snow at times overnight tonight into much of Sunday. Temperatures tomorrow will struggle to make it far. Forecast highs on Sunday in Rockford are over 20-degrees below average, with most of the area staying in the 30’s.
Highs will remain above the 32-degree threshold, but as we’ve seen several times in the past couple of weeks, that doesn’t mean snow cannot make it to the ground. Snow will be likely at times tomorrow with as much as an inch or two of slushy accumulation, especially south and east of Rockford. Pavement temperatures remain much too warm for much in terms of accumulation, but if snow is able to fall quick enough, it could be enough to overcome the warm temperatures.
A lot of uncertainty remains in the forecast. In this case, the difference between slushy snow and just rain will be a matter of one to two degrees. If highs climb close to 40, we’ll likely see more rain than snow. If temperatures struggle to make it much warmer than 35, we’ll likely see more of a mix of snow than rain.
Things do quieten down a bit as we usher in a new week, but the weather does remain pretty unsettled through much of the middle of next week. The chance for rain and thunderstorms exist Wednesday and Thursday, with highs in the 60’s to near 70.
