Calgary, May 26: West wind Thursday will generate local gusts in the low 40s for Calgary; that’ll be about the worst facet of the day.
Beyond, we’re looking at loads of sunshine for the morning, and a layer of cloud moving through as the day wears on. That cloud layer will blanket us through the evening hours, providing a layer of heat entrapment that should keep Calgary in the double-digits overnight. It’ll be fair weather to spend outside!
The west wind curls to southwesterly Friday; this is due to a trough sinking in, and with that, we’re keeping an eye on instability. The convective outlook may point to marginal storm potential for Calgary; with temperatures in the 20s, some areas may get a severe thunderstorm watch prompt. Still, it will be rather warm.
The westerlies aren’t done with us yet; that, combined with a blast of clarity, will create largely sunny conditions and only a slight chance of showers Saturday afternoon. That evening and into Sunday, we’re looking at Calgary’s – and southern Alberta’s – best shot for rain. The overarching model sets have been rather finicky with the details on our precipitation; more and more are they falling back before five millimetres locally, with the impact in southern Alberta barely clinging above 10 mm. We could use a boost!
Monday, too, has early showers; with that borne in mind, Calgary may top 10 mm, as well. Still, this is at the back end of the forecast, and with a passage across the Rockies still ahead, there’s no sense moving chips into the middle.
