Things are finally beginning to look up and those who are waiting for warmer temperatures will like what looks to be on the way for mid to late of this coming week. After our snow across portions of Illinois tonight, the main weather story that will take center stage will be the impressive signal for very nice weather on the way.

By Tuesday of this coming week, we can see things beginning to take shape out to our west. The upper ridge will be centered over the over the Four Corners region, near the Rockies while the eastern trough slowly pushes off to our east and closer to the East Coast. This upper ridge is the signal those warm weather lovers are waiting for and ridging usually coincides with a favorable setup for warm weather.



 

As we progress through this week, the upper ridge will slowly push east across the plains, eventually make its way to the Midwest by Thursday as model guidance is currently showing.



 

This upper ridging as you saw above will come with a storm system or two as well and also a few periods of strong warm air advection. The strong low level winds will aid in advecting warmer temperatures north and northeast from the plains and up into the Midwest ahead of each storm system that runs through the plains. As you can see below, there are two systems that run northeast through the plains, each with a period of warm air advection (in red). This will lead to a gradual warming trend across the Midwest, including the state of Illinois.

 

Without getting into specifics that would include cloud cover and potential frontal boundary passages during this timeframe, below is one models take on high temperatures across Illinois on Thursday and Friday of this week. So as you can see, the potential is there for widespread warmth across all of Illinois later this week.
