This week will be warm, but somewhat unsettled. A fairly potent weather system will bring rain and possibly thunderstorms to Southern Manitoba on Tuesday.
Monday
Showers in the morning, then becoming Mainly Sunny.
27°C / 13°C
Monday looks to be the nicest day of the week as we potentially experience our warmest day of the year so far. However, before that happens there may be some shower activity this morning along an approaching warm front. Once this front passes skies will clear and temperatures will begin to rise. High temperatures are expected to be in the mid or upper twenties, with skies becoming mainly sunny by the afternoon.
Tuesday
Mainly cloudy. Periods of Rain.
20°C / 6°C
Tuesday will be a rather unsettled day in Southern Manitoba. A strong low pressure system will bring rain and perhaps a few non-severe thunderstorms to the southern-most part of the province. The Red River Valley will be in the warm sector of this system in the morning, allowing temperatures to climb up to around the 20C mark before a cold front goes through later in the morning/early in the afternoon. There is a chance we may see some rain or a weak thunderstorm in the morning, but generally speaking the main area of precipitation is expected to pass to our north in the interlake area. Up north of Winnipeg heavy rain will be possible as a stream of moisture is lifted by this system and forms an area of rain. There may be some embedded thunderstorms within the larger area of rain, but they will not be very strong. The Red River Valley may see some wrap around rain on Tuesday night as the area of precipitation over the interlake slumps south. Precipitation amounts from this system will be nearly impossible to predict due to the potential for embedded thunderstorms. In Winnipeg we should see somewhere in the range of 5-10mm, unless a storm goes through in which case we’ll get more. North of Winnipeg upwards of 25mm is possible, but more precise estimates are too difficult to attempt.
Wednesday
Mix of Sun and Cloud
20°C / 7°C
Wednesday will see a return to more settled conditions as Tuesday’s system departs. Temperatures will be around the twenty degree mark with a breezy west wind.
Long Range
The rest of the week looks fairly seasonal temperature-wise, with perhaps a chance of light rain on Thursday and/or Friday. A first glance at the long weekend forecast reveals a chance of rain and near seasonal temperatures…but based on past experience, rain on May long weekend is usually a strong possibility…though I probably didn’t need to tell you that!
