Today's Outlook Map [Moderate Risk] - Plus: Yesterday's Summary Of Events

Here is today's severe weather outlook map:


Storms should begin to fire up early this afternoon and last late into the evening. Large hail and damaging wind gust will be the main feature of today's storms.

Yesterday afternoon, storms started extremely strong with two main cells (Lethbridge and Edson) both going purple on radar from the beginning and producing reports of hail the size of golf balls or slightly larger. After initiation, these storms morphed into a linear MCS (mesoscale convective system) producing intense lightning and incredible shelf structure, losing most severe qualities before hitting the city of Edmonton.

REMINDER: When reporting hail to #abstorm #skstorm please use a measuring tape, ruler, coins or golf ball, baseball, softball, etc.. Accuracy in measurement is very important in determining potential damage and risk to future regions. Photos of holding hail in your hands is not acceptable as people have different sized hands. Another common mistake is reporting marble size hail. Marbles also come in various sizes. If it is very small hail, please report as pea size.

***The best way to report is taking a photo with a measuring tape held beside the hail stones***

Here are some tweets of the action in Alberta last night:

Nice Looking Waterspout In Manitoba Today.

Incorrectly being reported as a tornado, this is a beautiful waterspout. See Weather Glossary below.




A waterspout was photographed today over Interlakes in southern Manitoba. At no point was it over land so this is a confirmed waterspout.

Environment Canada's Weather Glossary:
Waterspout
"A waterspout is a rotating column of vapour and water which extends from thundercloud to the water's surface. A waterspout looks like a tornado but is much smaller and weaker. The diameter of a waterspout ranges from seven to 20 metres and its winds from 40 to 80 kilometres per hour which is strong enough to flip a boat. A waterspout may last up to 10 minutes. Waterspouts, for the most part, form over some of the major lakes of southern Canada during periods of cool, unsettled weather, usually from mid-summer to mid-fall."

July 16, 2015 - Severe Thunderstorm Hits Regina [Four Videos]





A very busy day around the province of Saskatchewan started with juicy forecasts and lots of anticipation.

http://www.canadianprairiestorms.blogspot.ca/2015/07/todays-outlook-map-dangerous-weather.html

Just after noon as the hot sunshine peaked, southern gulf stream appeared and the cold front began to threaten, storms started to fire off, all across central Saskatchewan. With temperatures of only +8C in Cypress Hills and +15C in Kindersley, the heat wave finally met its match, knocking down weeks long 30 degree days. From northern Saskatchewan which collected large piles of small hail, supercells quickly filtered south. Warman was first with nearly 1 inch or toonie size hail. Then, another new set of cells formed further south with Davidson reporting gold ball size hail. Between 2 and 3pm, the entire province filled out with clusters of supercells. Two were seen east of Regina as captured in our timelapse video. Then just as things seemed to clear out, the weather radio blared out an alert and a sudden storm cell popped up right over the city of Regina.  Luckily no major damages here but more storms are forecast again tomorrow, further east.

Today's Outlook Map - Dangerous Weather Ahead!

Current conditions are showing a lot of potential with a strengthening southern gulf stream, cold front coming in from the west and lots of rain in the north. Prairie and Arctic Storm Prediction Centre mentions a possibility of tornadic supercells south west of Saskatoon later today. Otherwise, a straight line damaging wind event with supercells associated with the cold front will cross the province of Saskatchewan very quickly and land in southern Manitoba over night. Large hail and heavy rains are expected further north. Please head all warnings and take precautions. Loose objects should be secured, now and candles gathered/phones charged. This is a serious situation! Storms may not begin until late in the day but when they do, they are expected to cause damages with power outages likely in highly populated regions of Saskatchewan.

Here is the latest outlook map:
