August 2016 Forecast: Quite wet indeed!

July was near average and wet over much of central and southern Alberta. The northern Part of the province was warmer than average with and drier than normal with the exception of parts of northeastern Alberta. The wettest part compared to average was a wide band down the trans Canada highway in southern Alberta where accumulations surpassed records. This was due to day after day of never ending severe thunderstorms. The month of July was one of “stuck” weather patterns, this were pretty much the same in a given area form the majority of July.

As for August long range models(albeit somewhat in agreement) show a northward shift in the zonal jet which should shift the extreme rainfall events north as well. This pushes any warm anomaly even more north. Only the very extreme north will see above normal temperatures. Parts of the foothills may see well below normal temperatures and a high risk of early snowfall down into the valleys by the end of the month or early Sept(Deja vu 2014?) perhaps down to the major centres such as Calgary(yes I’m hinting at August snow Calgary!).


Aug 1-10: Very wet and humid in Central and Southern Alberta. Warm and dry extreme north.

Aug 10-20: Heavy rainfall over much of the province, frequent thunderstorms widespread. Warmer and drier as you go north

Aug 20-30: Very cold by August standards , snow comes early to the Rockies and foothills. There is a risk of unusually early killing frost in eastern Alberta. There is a chance of a quick shot of heat but overall cold and wet.

A quick note. A major change(possibly due to the natural Autumn variability) looks to take place sometime from mid Sept to Mid Oct and is pointing toward a very warm fall 2016. Many locations may see their highest temperatures of the year in September or October(particularly in places such as Red Deer and Rocky mountain house).
