Miserable Work Week With a Nicer Finish

     Today and tomorrow will be one word: miserable! Mainly cloudy skies, strong northwest winds, scattered showers and cold temperatures are in store. Today will be windiest with sustained winds close to 40 km/h at times. A few showers and drizzle are likely at times. Tonight, any precipitation that remains could even mix with some snow. No accumulations are expected. Highs today and tomorrow will hover only around 5 to 7°C, 10-15°C below normal for this time of year.

     The sun returns in full force on Thursday, but it will still be very cool for this time of year, only reaching around 10°C.

     Thankfully, warmer weather is in store for the long weekend with more seasonal highs in the high teens likely. Note that there are hints of another system early next week around Monday-Tuesday, but it is too early at this point to say what impacts it will have.

     The second half of the month is also looking warmer however (less below seasonal)... so that is something to look foreward to.

  1. I should mention that frost is likely Thursday morning with lows potentially between -1°C and -3°C. We're now getting to that time of year where it is worth mentioning...

    2. The link you included doesn't appear to work... nonetheless, the 1981-2010 normal last frost date is May 23 (last day to dip below zero).

      The latest frost on record was on June 20, 1972 when we dipped to -0.6°C.

    4. The only frost related sites I could find:

      http://planthardiness.gc.ca/ph_main.pl?LANG=en

      I don't have an archive for all southern Manitoba cities at this time so I couldn't make my own map right now. Perhaps in the future.

    5. Thanks JJ They were showing Hard frost warnings last night and today all the way south to Lordsburg N.M near The Mexican US Border (Arizona/Texas/New Mexico corner) southeast of Phoenix and ESE of Tucson. Daytime high temp norms there are near 38C or 100F

  3. A few flurries reported at the airport overnight and this morning... the latest occurrence of snow since 2009 when a few snowflakes fell on May 15.

  4. A downright miserable day today... feels like early April out there. We'll continue to see scattered flurries, snow pellets and showers at times.

    Sun comes back tomorrow and we should reach around 11 to 12°C. Similar on Friday, albeit a little warmer, reaching 14-15°C.

  5. I've noticed that E.C. has cut down significantly on the warming for the weekend and now have temperatures still well below the average for Friday thru Sunday.

    1. I think some of those highs are a little underdone. The GEM weather model has really cooled things off since yesterday, not the case in other models right now. Especially that 13°C for Saturday, I'm thinking more like 16-17°C right now. That 14°C on Sunday also looks underdone, right now I'm thinking more like 18-20°C. We'll see how the next few model runs go....

  6. Yeah, I think so too especially that it seems like this seemingly endless northwest flow aloft will switch to more southwesterly by next week. Also, for what it's worth, many long range models are hinting at a dose of summerlike weather for later next week with highs in the mid to upper twenties possible. Let's hope that this is indeed the case.

  7. A beautiful day in store, albeit a good 5°C below normal, only reaching around 13°C. We'll see a few clouds this afternoon.

    We warm up slightly everyday for the next few days... reaching around 16°C tomorrow, 19-21°C Saturday and 21-23°C Sunday. For once, a nice May long weekend! Enjoy it!

    Monday however wont be as pleasant with lots of cloud and possibly some rain.

  8. JJ, i've been hearing that long range models are indicating a summerlike warmup by the end of next week with temps possibly in the mid to upper twenties. What are your thoughts on this?

    Thanks, Anon

    1. That's what the GFS has been showing in latest runs.... Too early to say how long it will last. My initial guess would be not very long given the fact that both the NAEFS and CPC expect a greater chance of below normal conditions in the 2 week from now period.

  9. By the way, the low was -5.8°C at the airport this morning... 9th coldest low on May 15 on record....

  10. Jj the cpc now shows normal Temps for the next 14 days, maybe above normal. It's may and we're going into June likely turning the corner soon.

  11. The naefs shows the same as well and I think we should start being optimistic for once everything is good that way. :Do

  12. All I'll say is a turn to more prolonged above normal conditions is something I'll believe when I see it. Many times we've had our hopes up in the last 6 months, only to be dissapointed once we actually got closer. I wont be optimistic until more prolonged above normal conditions are forecasted within a week, rather than in a few weeks.
