July 2016 Forecast: A July like 2010/2011

Almost every long range model seems to point toward the coolest July in years. Then again the coolest after several hot summers is not exceptional by any means, June was a degree or two warmer than normal so near to slightly cooler July will only damped the warm 2016 year. Unless august were to continue to cooler, wetter weather.

Parts of central Alberta may not see their first 30C day until August or September. Or at the very earliest late July. Essentially locations that did not already hit 30C in May or June have a potentially long wait into late summer before reaching the “mark of summer”

July is expected to finish between 3C below average(top 10 coldest on record) to about 2C above average depending on which part of the province. The far north is expected to be the warmest compared to average, and will often be the hotspot. Other warmer areas include southeastern Alberta. The coldest areas compared to average will be in west central Alberta including Drayton Valley, Red Deer, and rocky mountain house. Edmonton and Calgary should finish up near normal.

Rainfall highest in west central Alberta and along the entire length of the foothills. This includes the centres of Red Deer and Calgary.

Thunderstorm activity will be very high, even with the cooler temperatures the ample moisture should allow storms to reach severe status often over the course of July. Similar to July 2010, and July 2011.


July 1-10: Mild and stormy over most of Alberta, very humid. Severe weather almost daily. Remaining hot and dry in extreme north

July 10-20: Pattern persists. Frequent SE gulf flow leading to very high humidity and mild temperatures. Frequent storm systems. Low likelihood of sustained heat other than in the north.

July 20-31: First chance of more significant heat, Likely not much more than high 20s over the majority of the province longer than a couple days at a time. However the very high humidity could make it feel more like the upper 30s. The higher temperatures could fuel thunderstorms significantly more violent than earlier in the month.
