After a heat wave that saw record setting temperatures twice in the southeast, Environment Canada is now expecting the daily temperatures to drop down towards more seasonal temperatures.

"What we've been dealing with over the last little while has been a dome of dry, hot air," says meterologist with Environment Canada Sara Hoffman. "Every once in a while we get a little bit of instability that passes through and brings these thunderstorms or chances of severe thunderstorms, but predominantly this dome has been pretty well entrenched. We call it a blocking pattern."

Blocking patterns can lock in a type of weather to a specific area for extended periods of time, such as the heat wave with little to know rain over the last few weeks, or it can go the complete opposite direction and force heavy rain clouds to stay in one area over a number of days.

The blocking pattern we have just come out of seemed to keep that heat while also blocking out any rain over the last little while, but that seems to be ready to change.

"From the Pacific we have an 'upper low', so an area of rain and instability, is moving eastward and it's strong enough that it's actually able to push that dome of hot air south, that dome that we've been experiencing lots of hot temperatures over the prairies, and it reestablished the flow so that the pattern will now be much more seasonal."

There is a storm headed towards the southeast but it seems to be much more seasonal. The storms we see in the fall have far less humidity to cause them thanks to cooler temperatures, meaning that we're unsure of just how much rain is going to fall in certain places, but it should be much tamer than our last few storms although maybe a little windier.

"This will seem like a very fall-like storm, so cool rain, very very windy, there is the possibility of a severe wind gust, that would be a gust of wind above 90 kmph depending on the exact orientation and track of the low pressure system, and some models are even anticipating that the extreme northern parts of Saskatchewan near the Northwest Territory border may get some snow too."

While we won't have to expect any snow here in the southeast, the weather is still expected to drop in temperature over the next few weeks. Forecasts are still much more accurate in the short term seven day span, but according to the trends we've seen, we could still see some +30 temperatures in Estevan at some point in September, but it's not likely.

"Looking at a climate record of what's possible for Estevan, certainly 30 degrees in September is very possible and it has happened before. It just depends on that the upper patterns and systems that come through, sometimes you'll get a warmer one and sometimes you'll get a cooler than normal one, but it is certainly possible."

There is some rain that is expected to drop a little bit in the southeast over the next few days, although just how much can be expected is still unclear, as is where exactly it will fall.
