Cold Halloween

     Miserable conditions for the next few days... Cloudy skies will dominate through to Thursday with chance of some drizzle and light showers or flurries each day. Best chance will be today. Not expecting much accumulation, if any. Very chilly compared to what we're used to however, with highs in the low single digits. It will also be quite windy out of the north-northwest today and Thursday. Lighter winds tomorrow.

     For Halloween, though it will be quite sunny, it will also be quite chilly. Only expecting highs in the low single digits after a morning low in the mid minus single digits. For the evening trick-or-treaters, a moderate southerly breeze will make it feel a little colder. Temperatures should be close to the freezing mark.

     So far, it looks like the beginning of November should be warmer than normal overall. Models hint at a more significant system early next week, but it's too early for any specific details.

Very Warm Yesterday; Cooling Down

     Looks like the warmer solution worked perfectly for yesterday. Winnipeg airport reached 20.6°C, not quite beating the old record of 23.0°C in 1989. However, it was the warmest we have been so late in the year since 1990 when we hit 23.8°C on October 26. Hopefully you enjoyed it because this was likely the last 20°C day of the year until spring!

     We cool off quite a bit for the next few days, but we'll still be above the 1981-2010 normal high of around 8-9°C. We should reach 12-14°C today and 13-15°C tomorrow. There could be showers tomorrow afternoon and possibly more scattered showers on Monday. Not expecting major accumulations at this point.

     Although we cool down mid week with highs in the single digits, no major and prolonged cool downs are expected for at least the next 2 weeks. In fact, chances are looking high that the first half of November will be warmer than normal overall. That doesn't mean there won't be any colder days, but any cold should be brief and not severe.

Fabulous Week Ahead Next Week

     Much cooler and cloudier today as we briefly return to brisk northwest winds. Luckily, this will only last 1 day and temperatures will start rebounding this weekend. Should start fairly cloudy again tomorrow, but we should see some sun in the afternoon.

     Warm flow returns Sunday and we should reach mid teens. In fact, the entire week is expected to be at least 5°C above normal, with highs in the mid to high teens. Some days could even get close to, or exceed 20°C. Records next week are still in the mid 20's, so so far it doesn't appear we're talking about record heat, but that could still change. Luckily, no end is currently in sight for the above normal temperature trend.

     This late month warm spell will ensure that October will finish well above the normal mean of 5.1°C. This is the 3rd consecutive warmer than normal month. Nice to see we've finally broken the cold trend, at least for now.

Pattern Change On The Way


     Just two more chilly days to get through and then things will get better! Still breezy out of the northwest today under cloudy skies and highs in the high single digits, a monotonous weather pattern which has been with us since late last week. At least tomorrow, the sun should be with us, but it will still be chilly with highs around 10°C.


Long weekend forecast:

     The weather pattern changes tomorrow night as a strong southerly flow sets up over southern Manitoba. It will be very windy in the afternoon on Saturday with southerly winds up to 40 km/h and gusts up to 60 km/h. Should see highs in the mid teens, closer to normal for this time of year. Mid teens are expected to continue Sunday and Monday. There will be a slight chance of showers on Sunday, but I'm not expecting much rain overall this weekend. Winds will be calmer Sunday and Monday as well, so overall, looks like a pleasant long weekend ahead!

     Right now, there are no signs of prolonged cool downs through to the end of October. In fact, long range guidance suggests a warmer than normal second half of October overall. The following map is just one forecast for temperature anomalies for the October 17 to 24 period. Have not seen this much agreement on above normal temperatures in a long time!
