Hopefully you took the time to enjoy today's sunny weather. Although cool, this afternoon was pretty nice with more sun than cloud. Looking at the image above...tomorrow looks to be a different story. This is from the latest ADONIS forecast model run for 8am tomorrow morning. As for the timing of tomorrow's rain, I'm pretty confident in this run's prediction. A few "sprinkles" in the overnight are possible with the first few bands of rain pushing in around 8am.
Between noon and 2pm (as you can see above) this model is calling for some very intense rain with possible thunderstorm activity. Keep in mind this is "future radar" and not an actual radar image that we're looking at here. Purple indicates intense weather on a radar image (anything above 60-65 dBZ for you weather nerds). This can mean very heavy rain, thundershowers and even hail. While I do not expect anything this severe tomorrow (most of that "purple stuff is still west of the city in this image) I do think that 10-20mm of rain could fall in a very short amount of time. While we're not talking about a flood situation with these amounts, some pooling of water on the roads is possible durning the "lunch rush" tomorrow which could make for a hectic commute around town.
Luckily for us, this system looks to move through the region at a quick pace. By tomorrow evening that "low" should be making its way to the east of our region by 8pm and I expect a clearing trend tomorrow night into Friday. All in all, as much as 25mm of rain is possible...but hopefully rainfall totals end up on the low end as our city's infrastructure is not always "100% effective" on handling a lot of rain in a short amount of time.

Rolling the ADONIS model ahead a few hours and things look good for the afternoon. An area of high pressure pushes in from the west and cleans things up. By the dinner hour we'll be firmly under the influence of that "high" but a low pressure centre will be on our region's "doorstep" that I expect will bring a few showers into the overnight hours with some rain into Thursday. Also, with the jet stream just south of us, we can expect cooler than normal tempertures to prevail over the next few days.
