Overall we are seeing a cooler and wetter spring overall in Alberta. With a rapid warm up as early as late April.
Winter was colder and near to wetter than average and these conditions are likely to continue at least half way into spring.
March(very cold and wet): March was so winter like I’m going to go and say it counts more as part of the Winter.
April(cold and wet): Cold and wet for most of the province, the exception being the more northern regions being slightly drier than normal. Major snowstorms will track across the province maintaining the winter look for much of the month.
May(Warm and wet): First signs of both spring and summer, Rapid temperature rise will likely make spring 2018 very very short weather wise. An example year would be 2013. This also spells worry as the snows at higher elevations will likely stay until the heavier June moisture builds. The quick increase in temperature and late arrival of warm temperatures should keep the fire risk way down. Flood risk very high
June(warm and wet): Short, but intense startup to the thunderstorm season sparked by high heat and humidity. Very high flood risk. Higher than normal humidity.
“summer clues”
Most seasonal models show a large ridge of high pressure stamping down on thunderstorm activity as the summer heats up. Long periods of hot,dry and storm-less weather in July, August, and September. Summer may turn out much drier than normal even after early moisture
