  3. I'm watching a live newscast stream from the WDAZ website. Sounds like things are getting very bad.

  4. The Flash flood warning extends back up the Souris to Sherwood near the Canadian Border where it has risen 4 feet since 7pm last night and is now 2 feet higher than the all time record

  5. Closer to Wpg the NWS Grand Forks site has a RRValley Storm report which shows most major sites had 1 to 2 inches or more by 7am this morning many still raining... on my name or

  6. Rob Did we have a similar setup in 2010 where gulf moisture was expressed up to our area from the Gulf
    What causes it?
    What changes the setup?

  7. from the Capital weather Gang Washington PostIn response, NWS issued a flash flood warning at 9:41 central time for Minot, urging residents to “move quickly” away from evacuation zones. Eleven thousand residents have been told to leave according to reports.
    On its Facebook page this morning, NWS posted the following about Minot’s levees:
    Levee protection in the city of Minot averages a height of 1,558 feet, with some low spots between 1,556 and 1,558 feet. Based on no additional rainfall, no unexpected changes in upstream releases, and no unforeseen breaches or failures of levees, the current forecast suggests the 1,556 foot level will be reached sometime this afternoon and that the record level of 1,558 feet will be broken, fully overtopping the levees by Thursday morning.

  8. The latest outlook from CPC for the summer months in North Dakota show a good chance of below normal temps and above normal rain... SIGH!
    I hope that they are wrong!

  10. I'd be fine with 25C for the rest of the summer.. as long as there was no more rain! This two days of sun and 4 days of cloud and rain just isn't doing it for me!! And we don't have it anywhere near as bad as the folks to our west..

    Mother Nature.. you can start that drought cycle for us any day now..

    Next chance of rain looks like Sun-Mon timeframe.. with a chance of showers and tstorms over southern MB/northern Plains..

    ReplyDelete
  11. Bring on the summer weather ..but as for a drought no thanks. I'd be curious to see precipitation anomalies over N Manitoba and NW Ontario so far this June.. the last thing we need is for forest fires to start up after all the flooding to our SW.

    We can still get warm, summer-like weather and normal precipitation if we are affected regularly by overnite MCS's. That is the ideal situation ;)

  12. Appears the Weather Gods are with you tonite at least.
    Has there been a better night for football?

  13. Rob!!!
    Some models are showing a very hot air mass heading into southern Manitoba next week! You think we could sneak 1 30+ day this month...???

    ReplyDelete
  14. We can hope! Models have been showing some heat moving in for the beginning of July for a few runs now.. and CPC outlooks are finally showing some above normal temps edging into the northern plains for the first time in awhile. So I'm cautiously optimistic that we may be seeing 30C by early July. Hopefully, it's a trend to a stretch of above normal weather, instead of just a brief warmup.

  15. Rob you might want to add this site to your links. All of the USGS Souris River Gage readings are on one page from where it leaves SK near Sherwood to returning to MB at Westhope ND

  16. Whats with over 30C today north of YellowKnife. Have we had one day yet?

    ReplyDelete
  17. Looks like that line of storms stateside near the international border is starting to bow out! Quite the wind storm with that line!!

    ReplyDelete
  18. Very intense line of storms in northern ND. Going to see if they impact me in the coming hours. Going to be a close call here in Altona.

  20. Heavy downpours here three times since 3pm and once again traffic on eighteenth reduced to a crawl at the bridge.

  21. Doing a great imitation of shock and awe. Last one is finished on south side with over 30mms so far on NE side of town. 25 near Minto on Hwy 10.

  22. Big time storm moving through the Gladstone area. 50 mm of rain in one hour is possible!

    ReplyDelete
  23. Should get in on some action in the next hour or two. Strong storms off to my west.

    ReplyDelete
  24. 50-75 mm in part of Brandon yesterday... 249 mm at their airport since May 1. Over 300 mm in Estevan since then too. What's going on???
    Yet only 99.5 mm at Winnipeg airport since May 1.
    What an odd year...

    ReplyDelete
  25. And EC has forecast rain every day for the next 5 days for Brandon and Souris. Must be a computer glitch,,,new word for SNAFU riiiight.

    ReplyDelete
  26. Finally,some hot weather to end the week! Seems the weather GODS have answered our prayers!!

    ReplyDelete
  27. Thanks EC for removing that raincloud icon from today's and tomorrow's Souris weather forecast. Now if the same can be done for Turtle Mountain a few kms south and Brandon a few Kms north we'll be ecstatic.

    ReplyDelete
  28. I changed the radar icon on my home page back to EC's radar image. I was using Weather Network's radar graphic, but it's been stuck on yesterday's image with the strong line of tstms over SW MB. Didn't want to alarm people that that was the current image!

  29. Some parts of Kansas are cooking under 110F degree heat today...Dodge city for example. I don't mind the heat, but that is a little too warm!!

    Much worse in my opinion is Oklahoma City at 100 F with a 67 F dewpoint.

    ReplyDelete
  30. And then there's Childress TX.. 117F today (47C)! I'd love to experience that one time.. (but probably just once! :)

    Looking forward to our mini heat wave later this week.. looks like we will finally hit our long awaited 30C mark by Thursday.

  31. Rob, you're not missing much. I spent a decade living in Kuwait (before moving to Saskatchewan). Just imagine a country-sized hairdryer on its highest setting, blowing on you all day and night long. Sometimes we would get a sea breeze dropping temperatures to 35 C in the afternoon (very close to the dewpoint!) but they would recover to 40 C in the evening, then slowly decrease again and reach a low of 30-32 C by sunrise. This was every day from late May to mid-September. We took showers only in the morning when 'cold' water temperatures were below 40 C. Never a cloud in sight all summer, much less rain.

    ReplyDelete
  32. addy..

    Wow.. a decade in Kuwait.. that would turn me off heat for awhile! The heat there is so intense.. routinely 50C or more during the summer.. punctuated by those lovely choking sandstorms. I don't think I could handle that for a summer.. but one or two days would be interesting to experience.

  33. By the way, I've recently moved my weather station in the backyard due to a sunroom addition to the house. The new location is still in the backyard but is sheltered by surrounding trees so my winds are notably lighter and not representative of actual winds. So until further notice, ignore winds from my Rob's Obs station.. especially from a northerly or easterly direction. I'll have to look into getting better wind exposure in the upcoming weeks or months ahead.

  34. For forecasters the great news about Long Term Forecasts must be that many baby boomers may soon believe long term is tomorrow.....That must be why I heard someone say that by Friday we will be looking at 40C temps and 45C Humidex readings.
    I mention this as by tomorrow I may forget it. By Friday....
