Cold Canadian high pressure is centered over Tennessee tonight, and ridges from Quebec in eastern Canada southwest across Texas into eastern Mexico. The ridge will effectively block any return flow of moisture into the midwest for the next several days. A good southwesterly wind flow is developing with the help of a pretty decent pressure gradient on the back side of the high. Origins of the air will be out of northern Mexico across western Texas for the next couple of days. This air is very dry, so we can expect lots of sunshine through Tuesday with temps warming to around 60 degrees on Sunday afternoon, into the low to middle 60's on Monday, and into the mid to upper 60's on Tuesday. A 70 degree reading or better cannot be ruled out for parts of northern Illinois on Tuesday afternoon. By Wednesday some moisture beginning to feed in from the Gulf will make for more clouds reducing temperatures a few degrees, and with a cool front approaching from the west, there could be some light rain showers. The front will blow on through the area by early Thursday morning leaving skies partly sunny on Veterans Day. It will be a little cooler, but not drastically so, with highs in the middle 50's on Thursday. The front will stall out near the Ohio river on Thursday night and begin moving back toward the north as a warm front on Friday as an area of low pressure develops over Oklahoma. Showers and some thunderstorms will develop ahead of that system Friday night into Saturday as some Gulf moisture gets involved, but nothing heavy is anticipated at this time. Cooler air drawn into the system, as it moves across northern Illinois on Saturday, will drop afternoon temperatures back down close to averages for this time of year... around 50 degrees for an afternoon highs.
By the way, don't forget to turn your clocks back 1 hour before you go to bed tonight. Daylight savings time will be over as we go back to standard time. How will that affect you? Well, instead of the sun rising at 7: 37 am on Sunday morning, it will rise at 6:37 am, and instead of setting at 5:43 pm Sunday afternoon, it will set at 4:43 pm. This will take some getting used to. I guess there is a positive aspect to this. We will all get an extra hour of sleep tonight!
