Thunderstorms did not materialize in the RRV and southeastern Manitoba overnight. However, widespread rains still managed to dump some decent rainfall totals. In Winnipeg, generally 15-25 mm of rain fell from yesterday evening to 9 am this morning, including:
South St Vital 21.8 mm
Norwood 21 mm (via Brad)
Charleswood 20.8 mm
Winnipeg Airport 18-19 mm
Winnipeg actually ended up on the lower end of things as most of the RRV and southeastern Manitoba actually got more. Generally, 25-45 mm fell in the remainder of the RRV and in southeastern Mantioba. Steinbach, Morden and Somerset have received some of the highest totals with 43.1 mm, 41 mm and 44.0 mm respectively, since yesterday (according to Manitoba Agriculture and Environment Canada).
Highest totals so far have been in southwestern Manitoba and in the Interlake. Generally 40-50 mm has fallen in the Interlake in just the past 9 hours. Even higher amounts of 45-65 mm have already fallen in extreme southwestern Manitoba, west and southwest of Brandon:
Reston 63.6 mm
Pierson 62.2 mm
Melita 54 mm
Bede 52.8 mm
Virden 46.1 mm
Deloraine 42.6 mm
Rain will taper off later this morning for the RRV. As the centre of low pressure and a cold front swing through this afternoon and evening, thunderstorms may develop. Some of these may be strong with hail, strong winds and funnel clouds possible. However, severe potential is contingent on some sunshine in southern Manitoba today. There is some clearing moving in from North Dakota this morning, but it's still hard to say if this will fill up with cloud later on. Depending on how much sun we can get, severe thunderstorms will be possible in the RRV and southeastern Manitoba. It will also be quite humid this afternoon with dewpoints in the low 20's, forcing temperatures into the mid 20's for some.
MUCH colder tomorrow behind the system. Temperatures will remain steady in the low teens. This, combined with breezy west-northwest winds and shower activity, will make tomorrow feel more like October.
Warming up later in the week with highs in the high teens Tuesday, low 20's on Wednesday and even warmer for the end of the week.
