Unsettled weekend but heat building in next week

Issued: Monday, July 21, 2014 · Covering: July 23 – July 30, 2014

This map shows the total precipitation across the Prairies so far this growing season compared to the long-term average. Most of the Prairies have seen average to well-above-average amounts, with the wettest areas located in a northwest swath from Brandon to just west of Saskatoon.

The first half of last week’s forecast was pretty much spot on, as the forecasted trough of low pressure moved through our region last weekend bringing with it a mix of sun, clouds, warm temperatures and a few showers and thundershowers.

For the first part of this forecast period high pressure looks to dominate, bringing mainly sunny skies and seasonable temperatures. By Friday, an area of low pressure is forecasted to begin sliding across the southern Prairies. This low doesn’t look to be that strong, but it will take a few days to move through. Friday will likely be cloudy with occasional showers or thundershowers and highs expected to be around 20 C under the clouds.

Saturday is a little tougher to figure out. It could be another totally cloudy day with showers or we could see a mix of sun and clouds. If we do see some sun then there’ll be a good chance of afternoon thundershowers or storms. The low will be pulling out of the region Sunday, bringing sunny skies to western regions and partly cloudy skies over eastern areas. High temperatures will likely be in the low 20s on Sunday.

For the first half of next week we should see high pressure building in bringing plenty of sunshine. This area of high pressure is forecasted to slowly move off to the east as the week progresses. This, combined with a developing area of low pressure to our northwest, will help to develop a southerly flow of warm air into our region. Highs will steadily warm during the week, with highs expected to be in the low 30s by Wednesday.

Usual temperature range for this period: Highs: 21 to 31 C, lows: 9 to 16 C
