Showers and scattered thunderstorms possible tonight.. cooler weather moving in Monday
A cold front over southern Saskatchewan will push eastward across southern Manitoba tonight. This front will trigger some showers and thunderstorms over western Manitoba this evening.. some possibly severe.. before they move into the Red River valley overnight. Rainfall amounts are not likely to be heavy as the band of showers will be fairly short lived and fast moving, but local amounts of 5-10 mm with up to 20 mm in thunderstorms are possible. The line of showers will move east of the RRV overnight with cooler weather on tap Monday along with clouds, brisk NW winds and a chance of showers. Temperatures are only expected to be in the low 20s over the next couple of days. Drier and warmer weather is expected Wednesday before another chance of showers Thursday. Overall, it looks like temperatures will be averaging near to slightly below normal over southern Manitoba over the next week or so. (Ignore the eternally optimistic warm and sunny Day 6-7 forecast.. it has a warm and dry bias and fails to capture cooling trends properly)

I washed my car today, which is usually the signal to the weather gods to rain. So if all is equal, it should rain just as I leave the house to go to work in the morning.
ReplyDeleteI'm getting kind of fed up with EC's severe weather warnings...there are cells in Eastern Saskatchewan right now. My friend just sent me a picture they took to their phone 5 minutes ago...a small rope tornado (touching the ground so yes, a tornado) just north of Canora, SK. Yet the cells in that region have no warnings whatsoever. If you would like to see the picture I can post it, also.
ReplyDeleteHi:
ReplyDeleteCan you post that picture of the rope tornado?
Did your friend bother to call EC to report this tornado?
ReplyDeleteCanora isn't covered by doppler radar (just plain'ol regular radar), so EC would not issue a specific tornado warning for that area unless they received a credible report.
ReplyDeleteI believe there's a watch for the Canora, SK region. That should be enough in itself to warn people of inclement weather. If you take the time to read EC's watches they happen to tell people to "remain on the lookout for severe weather". I don't think there's any need to start up EC "bashing" on this blog... take the time to actually get educated about severe weather and your surroundings and then call in the report instead of bashing EC.
ReplyDeleteNo, he said no warnings whatsoever, which is true. However they do have a watch for that zone.
ReplyDeleteTo be fair to EC, the latest model data available for Canora does not exactly suggest tornadic activity would be possible. Indices for 6 pm at Canora: Showalter -0.3, LI -5.1, CAPE 1080, and Storm Relative Helicity only 18. Apparently the model was wrong.
ReplyDeleteIndices from the NAM model are only marginally more unstable. Helicity does have a little spike at 6pm to 111.
I'm hoping that those storms into western Manitoba will hold together all night, looking foward to a good light show!!!
ReplyDeleteLooking at the RADAR, Brandon is gonna get wacked with a CB in an hour!
ReplyDeleteTornado warnings for southwestern Manitoba!!!
ReplyDeleteanonymous..
ReplyDeleteI wouldn't get too discouraged with a non warning on a brief weak tornado out of Doppler radar range. Even if EC receives a tornado report, they may decide not to issue a warning based on the timeliness of the report, or signs that the cell may have weakened or dissipated, or the cell was in an environment that wasn't supportive of further tornado development. Tornado reports are taken seriously, but EC must also be careful not to issue a tornado warning if the threat is very low or over (cry wolf syndrome). If they think the tornado threat is still high based on a report, they will of course issue a tornado warning.
So it is very important that people continue to send reports of severe weather to EC whenever possible to help them in their decision making process and post event analyses. The more information they have, the more effective warnings can be issued for everyone's benefit. Send reports of severe weather to storm@ec.gc.ca.
Doesn't look like this line will hold together all they way to Winnipeg. Strongest cells going to our southwest, and some to the north.. again! Hopefully some stuff fires up in between the two main areas as it moves across the RRV tonight..
ReplyDeleteLooks like these storms are moving along the border in kind of a slanted fashion, i also see that they are trying to spit up storms north of it and to the east of it. A very unstable environment so far, will see if we get a good lightshow to the south.I wonder will EC issue warnings around here?
ReplyDeleteBest looking Night in years.
Rob I beleive some of the cells are giving their energy to the northern teir, as a squall line always does. So I assume we'll see something similar looking in the north as the south does. whats odd is that these look to be moving southeast when they are actually slanted and moving completly east because I don't see any southward progression in the south part just plain east. So they are moving toward us. 50-50 chance of either mising or hitting.
ReplyDeleteLooks like those links are too long...here are shorter links to the images...

I think you'll want to put a facebook icon to your site. I just bookmarked the blog, however I must complete it manually. Simply my suggestion.

Thanks for the pics.. looks more like a funnel cloud than a tornado to me, but it may have touched the ground briefly. (Sometimes a funnel cloud may look like it's touching he ground, but it's actually obscured by hills and trees.)
ReplyDeleteLooks like the protective shield theory still lives on :o
ReplyDeleteOoops we missed it again.
ReplyDeleteThe radar showed rain.
But it split up again.
Oh when will it rain?
Bad Britney Spear lyrics aside, showers and thunderstorms once again bypassed Winnipeg and the northern RRV last night. Rain got as close to Winnipeg as Brunkild, Domain, Niverville and Steinbach with about 5 mm in those areas according to CWB mesonet, with 10-15 mm over parts of southern RRV including Morris, St Pierre and Dominion City.
Another chance of showers for us later this afternoon with daytime instability in the dry slot, maybe even a thunderstorm to our east, but rainfall amounts won't be much as airmass becomes drier and cells move quickly.
6 weeks and counting since Winnipeg Airport has had a rainfall of 5 mm or more (last time was back on June 22nd when they picked up 7 mm).
I give up!
ReplyDeleteTime to install a comprehensive irrigation system. At least the Seine River is close, I can steal the water from there.
Being out in Red Lake this last weekend I was sure close to the forest fire action there. That smoke actually made it to Winnipeg last night!
ReplyDeleteIt's ok Rob, .....you can just admit that you have a stockpile of Britney Spears cds :-)
ReplyDeleteI just don't remember anything about rain and radars in her songs though.....
ReplyDeleteBuffalo, I give up as well. If we don't get a good storm before the seasons over we will live until next year. If we get a storm even if its light in strength, I'll be happy I know you will too. Somehow we need to divert the water from lake manitoba to here in the peg using a irragation system as to what you were reffering to. It's Just Another stinker of a summer.
