Forecast – for Jul. 21, 2011

Just like with cold weather, when hot conditions build into a region it can sometimes be difficult to break that weather pattern, and this is exactly what we saw at the beginning of this week.

By mid-week we should see a break from the hot, sunny weather as an area of low pressure slowly tracks across central Manitoba. This low will bring a good chance of thundershowers and storms on Wednesday and possibly into Thursday. With the increase in clouds, temperatures will cool off a little bit, with highs in the mid-to upper 20s.

The forecast for the weekend right now is a little tricky. Low pressure is forecasted to develop once again to our northwest and then track across northern regions over the weekend. This low is forecasted to have a trough of low pressure to the south of it, which will likely bring the chance of more thunderstorms to all regions over the weekend. Temperatures look like they’ll be fairly warm and could get quite hot if we see enough sun. Humidity levels may also come into play once again.

Once this low moves by it will try to bring down some drier and cooler air, but at the moment it doesn’t look like the southern ridge of high pressure will give up too easily. Temperatures do look to be a little cooler to start next week, with highs forecasted to be in the mid-to upper 20s, but I wouldn’t be surprised if we then creep back into the low 30s.

Usual temperature range for this period. Highs:22 to 31 C Lows:9 to 16 C
