We will see some high cloud move into the city today ahead of a low pressure system moving south of the border. This system will bring showers to areas close to the US border tonight and tomorrow. However, exact rainfall amounts will be tough to predict for that area due to the fact that there will be a sharp line between the high amounts and the nil amounts. This sharp line could end up right along the US border or a bit north. If the further north track verifies, 10-25 mm would be possible for border towns such as Melita, Morden, Emerson and Sprague. However, if the southern track verifies, look for just a few showers with little accumulation. We'll have to wait and see. Winnipeg is expected to just remain mostly cloudy tomorrow.
Beyond that, it looks like we may see some slightly warmer temperatures mid week with highs in the low to mid twenties, which is only seasonal now. This will continue until the weekend when another strong system could potentially affect southern Manitoba. We will have to keep a close eye on this one as it could bring some heavy rainfall to some areas if it does materialise.
In the longer range, there aren't any strong signals of a significant turn to warmer and more prolonged above normal temperatures just yet.
UPDATE June 6, 2013: Looks like there's a good chance of seeing some warm weather next week with perhaps a day or two in the high 20's. There could also be an increase in humidity. Will have a new post tomorrow.
