    John's Weather Journal October 8

    Nice to have a light wind morning. Don't get too used to it. Winds will be gusty again this afternoon and that is the trend over the next 6 days with the exception of Saturday. 
    We'll see varying amounts of cloud and sun with Thursday being generally cloudy and Friday being a little brighter. Temps will be climbing as we approach the weekend, fall off a bit on Saturday, then get mild again on Sunday. 
    Let's talk about the reason for the very gusty winds on Sunday and through at least the first half of next week. A couple of low pressure centres will move across the north and into the Hudson Bay area, then sit there for several days. As high pressure tries to move in from the west, the low blocks that movement. The resulting 'squeeze play' between the high and the low tightens the pressure gradient and causes the strong winds through northern and southern Manitoba. It's kind of like squeezing wind through the buildings at Portage and Main. It has to speed up to get through that narrow area. As long as that deep low sits over Hudson Bay, we'll have gusty winds. 
    On Thursday, I'm tracking the first low across the northern part of the prairies. It will bring rain at first, then a rain/snow mix to areas like Flin Flon and Thompson late Thursday and into Friday morning. That system will continue to move east on Friday. This could be the first accumulating snow of the season for Manitoba.

    Clouds will drift in and out today as we experience above seasonal temps but slightly cooler temps than Tuesday. We should remain fairly dry over the next several days as a surface ridge builds into the eastern prairies. Winds are still on the breezy side Wednesday and Thursday, but stronger on Friday and again on Sunday. 
    A low pressure system forming off the west coast will track across the northern part of the prairies though the day on Thursday. It will bring mostly rain to Alberta but will likely bring snow to Manitoba on the north side of the low by Thursday night and Friday morning. Computer models are laying down a decent swath of white stuff through the north end of the lakes by Friday morning. Areas like Thompson and Norway House are certainly part of that plan. I'll be tracking that carefully on Thursday. 
    You'll notice in the 7-day forecast graphic below that I mention the chance of flurries for the south on Tuesday morning next week. That really depends on our morning temperatures. If we have enough cloud cover overnight, it may be warm enough to fall as rain. Worth watching though.

    The dominant feature in this week's weather is the wind. Each day this week, we'll have afternoon winds gusting to between 40 and 60 km/h. Tuesday afternoon, the support for those gusty winds comes from the upper level jetstream making a shift right over southern Manitoba. There is also a chance for some late afternoon and early evening showers under that jet before skies clear tonight.
    Wednesday isn't quite as windy and fairly sunny. That is also the start of a stretch of dry weather that takes us through the weekend. Temperatures during that  period will be seasonal or higher by at least a few degrees. Right now, Sunday looks like the warmest day at 21 degrees, but before you call for a tee time, know that winds will be very strong again on Sunday afternoon.
    Looking at the start of next week and there isn't much agreement in the forecast models. I'm going with a cloudy and somewhat soggy start to next week. I have rain in my forecast both Monday and Tuesday.

    Again this week, we have a whole bunch of gusty wind to contend with.
    As of 1pm, we are seeing the showers push to the east of the Red River Valley and the sun is starting to come out as well. It will be mild this afternoon at 18 degrees but the winds will gust to 50 km/h from the northwest. 
    Skies continue to clear through the evening, but clouds move back in overnight. I'll be tracking another low pressure system across the central part of the province on Tuesday. We'll start Tuesday with some cloud cover but see some clearing and a chance for showers on Tuesday afternoon. Winds will be at 40 to 60 km/h as the next cold front moves through. 
    Wednesday will be slightly cooler (closer to seasonal) and still windy. Wednesday also starts a dry stretch of weather that will last into next week.

    A chilly start to October all across the province. As I write this at 1pm, we are at 5 degrees in Winnipeg. The normal high is now 14 and we'll be at around 8 degrees this afternoon. The good news is, winds are gradually dropping off. 
    Expect a low slightly below zero tonight but don't expect a frost advisory from Environment Canada. As we get to this point in the fall, advisories aren't issued because frost is much more common and we expect frost more frequently. 
    This cool trend will last for a few days. I'm expecting highs in the single digits on both Friday and Saturday. Expect a fair bit of cloud both days as well and some showers Friday late night and Saturday afternoon. 
    Sunday gets us back to seasonal conditions with a sun/cloud mix. 
    In the north, the word 'flurries' has been creeping into the forecast discussion. In Thompson though, it's only a slight chance today and it's more rain than snow starting Sunday and into early next week.

    John's Weather Journal September 30

    I'm tracking a low across the Northern Territory that has an associated cold front. That front is slumping through the province today. That explains the storng northwest winds that will gust to 70 km/h at times, likely later in the day. That will create high wave action on the southeast shores of the big lakes. Water levels could rise by 5 feet. The province has issued a warning. 
    As this system passes, a cooler weather pattern is with us to end off the week. Highs will be in the single digits for a few days and I'm expecting a fair bit of cloud on Friday and Saturday. We can also expect showers Friday night and occasional showers on Saturday. 
    Sunday should get us back into sunny skies and slightly milder conditions. A warmer weather pattern moves in for at least the first half of next week.

    A decent morning out there ahead of a windy afternoon. Winds will gust to 50 km/h from the northwest later this afternoon as we get to 18 degrees. 
    I'm tracking a low across the Northern Territory that has an associated cold front. That front will start to slide southward tonight into Wednesday and change up our weather. Wednesday will be cloudy and windy with occasional showers throughout the day and into the evening. Winds will align nicely with the longer fetch of the south basins of the big lakes so lake effect showers are likely. Expect gusts to 70 km/h over the relatively warm water. Wednesday will also be cooler at 12 degrees. 
    As this system passes, a cooler weather pattern is with us to end off the week. Highs will be in the single digits for a few days and I'm expecting a fair bit of cloud on Friday and Saturday.  
    Sunday should get us back into sunny skies and slightly milder conditions.
