 Ralph Wright, manager of the agro-meteorological applications and modelling section with Alberta Agriculture and Forestry (AF) analyzes the data.

Synopsis

Over the past week, a major rainfall event occurred over the northern half of the province brought significant rain to many areas north of Edmonton. Says Wright, “The storm was centered in the Slave Lake area with two stations reporting more than 150 mm. It was also wide spread, with more than 40 mm recorded across a large area - from Athabasca to Fort Vermillion. Upwards of 50 mm was recorded across the northern Peace Region. This area has generally been drier than normal since 2002.”

Elsewhere across the province most lands were under the influence of strong convective thunderstorm activity resulting in wide spread hit and miss showers. “Many stations received 10 to 20 mm, but there were also several widely scattered areas that received less than 10 mm. These places will need rain very soon,” adds Wright.

Soil Moisture Reserves

“Across the province soil moisture reserves are highly variable,” explains Wright. “It ranges from one in six to 12 year highs through parts of the northwest, to one in 50 year lows across a large area from Airdrie to Fort Macleod. In fact, many lands south of Red Deer are quite dry heading into the peak growing season, and timely rains will be needed to maintain adequate crop growth.”

Wright adds, “For those areas south of a line running through around Drumheller, June rains are critical along with adequate soil moisture reserves. July typically marks the beginning of an abrupt drying trend that persists along with hot weather well into August.”
