High pressure to dominate this week

For most of this forecast period it looks like our weather will be dominated by high pressure. This will result in dry conditions, with temperatures starting out on the cool side and slowly warming to around average for this time of the year.

A deepening area of low pressure over Eastern Canada will help an area of arctic high pressure slide southward into Manitoba during this week. This high will keep temperatures fairly cool to start, with high temperatures struggling to reach 10 C on Wednesday. As the high slowly slides southward it will begin to warm up under the strong spring sunshine, so we should see temperatures warming into the mid-teens by the weekend. Saturday looks like it will be the nicest day as the centre of high pressure will be directly overhead, resulting in plenty of sunshine and light winds.

Thunderstorms and straight-line winds

Straight-line winds in thunderstorms can cause as much damage as a tornado and are next on our weather school list exploring how and why severe summer weather forms.

To start next week, this area of high pressure will be well to our southeast. At the same time, low pressure will develop to our west. This will result in fairly strong southerly winds and will help to bring more moisture into our region resulting in more clouds. With the clouds, daytime temperatures will continue to be in the upper teens, but overnight lows will be milder.

The western low is then forecast to push through our region on Tuesday or Wednesday. This will likely bring fairly widespread showers to most areas. Looking further ahead, the weather models show fairly typical early-May weather, with highs in the upper teens to low 20s and several chances for rain.

Usual temperature range for this period: Highs, 7 to 21 C; lows, -4 to +6 C.
