Everyone brace yourself: drier air is on the way. In fact, by this evening it will start to be quite noticeable. Before the drier air arrives, some day time showers are possible so don’t give up the umbrella yet. What about our beloved upper low? Do you know I was talking about it this time last week? It takes a ferocious cold front Friday to kick it out to sea. Behind the front, October comes in like a...tiger. Hope your heater is ready.
Today (Thursday): Dry air is lurking to our west which pushes through during the course of the day. Before it arrives, there’s a 50-60% chance of showers and thundershowers across the region mainly from dawn into the early afternoon. A quarter of an inch of rain is probably all these showers can muster. By later in the afternoon skies break and winds from the west bring that breath of lower humidity we have waited for. Highs spike in the late afternoon in the mid-to-upper 70s. Confidence: Medium-High
Tonight: Dry air is really pouring into the region now and skies are a lot less cloudy. An evening excursion is well worth it as readings reamin in the upper 60s to lower 70s and breezes are light. Overnight lows drop off much more readily and end up in the mid-to-upper 50s.

Tomorrow (Friday): This is more like it! Dry and mostly sunny. Winds pick up from the west at a brisk 10-15 mph. The atmosphere overhead is getting a lot cooler. At the surface, it is still a delight with highs mainly in the mid-70s. Confidence: Medium-High
Tomorrow night: The cooler air starts to pour across the area this evening as the breezes from the west keep up their tempo. Skies should cloud up but not until late and some light rain showers are possible by morning. Evening readings fall through the 60s. Lows should end up in the mid-40s west of town to lower 50s in the city. Confidence: Medium-HighA LOOK AHEAD
Saturday can best be described as a motley mix, as clouds come and go and a few isolated showers dot the pavement in about 30% of the area. Winds howl at 15 to 25 mph, gusting to 35 mph, as the heart of the Canadian cold air funnels into the area. What is even more bracing is the lack of a warm up and highs are likely to do no better than mid-to-upper 50s. We might challenge a record for coolest high on that day. The evening should be clearing and winds should still be adding a chill that requires a serious jacket. Lows should drop to the low-to-mid 40s. Confidence: Medium-High
Sunday is a little less windy but still has an ever changing mix of clouds and sun. No more shower threats though. Temperatures still struggle and are likely to surrender at the upper 50s to lower 60s level. Overnight lows are chilly with most in the low-to-mid 40s but stray upper 30s are quite possible in the far western suburbs. Confidence: Medium
Monday looks, you guessed it, beautiful. Mostly sunny dry and mild. Highs reach the respectable mid-to-upper 60s. Confidence: Medium
