Monday, August 3rd 2020, 10:28 pm - The recent stretch of severe storm threats continues Monday, with the risk once again building into central Alberta.
Tornado warnings were briefly issued on Monday afternoon, however, they have since ended. Though the severe weather potential continues to linger in Alberta, Tuesday holds a bit of a reprieve, aside from some non-severe risk in Saskatchewan, and looks to usher in a dip in temperatures. Storm risk, however, will return to the western Prairies later in the week. A closer look, below.
- Threat for severe storms moves into central Alberta Monday
- Large hail, damaging winds, heavy rainfall hazards
- Slight cooldown Tuesday, Wednesday, with short break from stormy weather
- Keep on top of active weather ALERTS in your area
MONDAY: STORM RISK SHIFTS SOUTH, COOLER TEMPERATURES TO FOLLOW
Monday's storm driver looks to be a sharp upper trough crossing the Rockies, triggering storms in the mid-afternoon hours. Any storms that do spark are expected to fire up west of Calgary and Red Deer and southwest of Edmonton.
The storms may reach severe criteria in the evening in central areas, from Calgary to Red Deer, possibly producing large hail, heavy rain and damaging winds.
Daytime highs remain slightly on the warm side, though dropping down closer to the mid-20s for much of central and northern areas. The hottest daytime highs remain confined to the southern locales, where a few spots will exceed 30°C.
TUESDAY AND BEYOND: SHORT BREAK FROM SEVERE WEATHER THREAT
The remnants of some of Monday's storms will pass eastward into Saskatchewan in the overnight hours, though will be quite weak by then. That province hosts most of Tuesday's storm risk, though much reduced from recent days.
However, Alberta's break from severe weather will be short-lived, as an upper trough moving in from B.C. will bring the risk back to the province Thursday. By Friday, the threat will move into the eastern Prairies.
Temperature-wise, the ridge of high pressure that has kept Alberta warm in recent days begins to move off somewhat, bringing temperatures down a few degrees to the mid-20s for Tuesday and Wednesday.
Keep an eye on the forecast through the weekend.
