    John's Weather Journal July 18

    Warmest day of the week today with highs up around 31 to 32 degrees all across the south. We do get a little breezy tonight but it will stay mild well into the evening hours. 

    This upper ridge is also bringing warm temps to the north. There is still a heat warning in effect for The Pas and Flin Flon regions with 30 degree heat on the way again today.  

    That heat will likely end later in the day with some strong thunderstorms through central Manitoba. As of 1:41pm, there is a severe t-storm watch in effect for parts of Saskatchewan and The Pas and Swan River regions.

    I’m tracking a different low pressure system that will move through the Dakotas on Thursday. This one will spread some rain northward into southern Manitoba on Thursday afternoon, evening, and into Friday morning. 

    We can also expect some of that rain to be in the form of thunderstorms. 

    It’s likely we’ll see some showers Friday morning from Winnipeg east, then gradual clearing as the afternoon progresses.

    Nice rebound in temperature as the surface high pressure gently slips to the east of the Red River Valley. We are now in the return southerly flow and starting to warm up. 

    Tuesday will be a light wind day at 27 degrees in the sunshine. Wednesday, a little breezy but another warm and sunny one at 31 degrees. 

    By Thursday morning, we’ll start to notice more cloud cover, especially to the west, and some rain. A low pressure system will move through the Dakotas and circulate some moisture up into southern Manitoba.

    The showers and possible thunderstorms will likely wait until mid day or the afternoon on Thursday, and clear out on Friday. 

    By Friday afternoon, we’ll see some sunshine again and temps in the mid 20s.

    Monday will be the coolest day of this week, and the coolest since June 4th. Expect high temps across the south to be right around 21 degrees. That’s 5 degrees cooler than normal. 

    The rebound is fast though. Tuesday will be a light wind day at 27 degrees in the sunshine. Wednesday, a little breezy but another warm and sunny one at 31 degrees. 

    By Thursday, we are back into some rain. A low will move through the Dakotas and circulate some moisture up into southern Manitoba.

    The showers and possible thunderstorms will clear out on Friday.

    A heat warning remains in effect for all of southern Manitoba. A heat warning is issued when we have 2 consecutive days of daytime temps 32 degrees or higher and nighttime temps of 16 degrees or higher - or - when the humidex is 38 or higher for 2 days. 

    Friday and Saturday will more than satisfy that criteria. Saturday will also be quite humid, and quite windy. 

    Heat Warning From Environment Canada
     

    The heat breaks with a good old fashioned southern Manitoba cold front / thunderstorm Saturday evening here in the Red River Valley. That will happen slightly earlier for the west and a little later for the eastern regions.

    Sunday will bring a quick return to sunshine but will also be much cooler (more comfortable) with a high temp of 24 degrees. Sunday’s winds will also be a little gusty in the afternoon.

    Monday will feel like fall, well, not really but it will be a cooler day at 21 degrees. It’s a short break form the heat though. 

    The rest of next week is right back to seasonally normal 26s and 27s for daytime highs.

    You can really feel the change in humidity levels today. It’s still a little sticky out there with a dew point temp of 17, but certainly not the 23 degree dew point we had on Wednesday. 

    We’ll stay with the sunny skies and gusty west wind for the afternoon, but winds drop tonight in time for another mild evening.

    Friday and Saturday will be scorchers. Expect highs both days in the low 30s. Saturday will be windy out of the south ahead of a cold front which brings a stormy break in the hot weather.

    The timing of the front (and the storms) should be late afternoon or early evening here in the Red River Valley. That would mean more like mid afternoon for the west and later in the evening for SE Manitoba and NW Ontario.

    An early afternoon storm rolls through the Red River Valley and then east. A severe thunderstorm watch is in effect for all of the southeast.

    This is all connected to a big low situated over central Saskatchewan. As the cold front moves through southern Manitoba this afternoon, it slices through dew point temps up around 20 degrees. 

    Behind this system, a return to sunny skies and a continuation of the hot weather through the rest of the week. Humidity levels will drop though for Thursday and Friday. 

    The next chance for storms through the south is late on Saturday evening. Sunday brings a break from the heat with highs closer to the mid 20s.

    As of Monday, the normal temps in southern Manitoba are 13 for a low and 26 for a daytime high. That's about as high as they get all season. 

    We'll be consistently warmer than that normal high all week. Expect a sunny 27 today, then highs between 29 and 31 through Saturday. 

    There are a couple of opportunities for a sprinkle over the next couple of days, a slight chance Tuesday morning and slightly better chance on Wednesday morning.

    Winds will also be on the stiff side Wednesday and Thursday. Expect gusts to 40km/h at least both days. 

    We finish the work week with a sunny 31 on Friday before a slightly less stable Saturday and the chance of a late day thunderstorm.

    A strong surface high pressure along with an upper level ridge is responsible for the heat you’re feeling all across the province today. Even the north is in the upper twenties with sunshine.

    There is a heat warning in effect for west central Manitoba and all of the south that talks about mid 30s heat and humidex values of 40+ for Saturday.  

    Heat Warning for Saturday
     

    It will be hot and humid, and all we need is a trigger to get some storms developing. Looks like that trigger will move through in the late afternoon. 

    A cold front will wedge its way into that hot and humid air but there is a capping inversion in place. 

    Capping inversions are tricky because they can inhibit storm formation, but if the cap breaks, rapid formation of severe storms can happen. 

    As of Friday, it looks like that formation of storms could be east of the Red River Valley. However, if it happens farther to the west, we could see big, gusty, dangerous storms through here in the late afternoon and early evening. 

    From there, they move east into cottage areas around the Whiteshell and NW Ontario. Western cottage regions should be okay. 

    The timing of this cold front and where the storms happen is still uncertain. Be prepared anyway. There is a Bomber game, the Folk Festival, and the airshow in Portage where large groups of people will be gathering. 

    After that stormy weather passes, humidity levels drop a bit but we are still up in the 29 to 30 degree range right through next week.
