What??!!! Another Colorado Low?!!! 😔😔😔

 

Much of southern Manitoba and our region in general has received well over our average monthly rainfall, with the ground . Another Colorado low is poised to impact southern Manitoba, this is significant as the ground is already saturated from previous rainfalls with overland flooding already happening, some areas still are dealing with frozen soil from this winter season. This is not good news for flood outlooks.  A rainfall warning is in effect for Manitoba regions find out more here.., www.weather.gc.ca Read on to find out how much rainfall we will be receiving and what impacts we can expect from this Colorado low

. The rest of Friday: As I write this blog a batch of rain is now moving into southern sections of Manitoba, a large Colorado low pressure system is revving up to bring significant amounts of rain to Manitoba. We will be on the northern edge of this system , as a result the trough extending north of this system will likely create the perfect environment for heavy rainfall in the synoptic form (widespread form). This late afternoon and early evening the rain is expected to blossom and the first batch of precipitation will travel north through the evening. As for temperatures much of the area has already reached our daytime highs, with areas reaching the high single digits to the low teens. Areas in the interlakes more so in the mid single digits. 

Tonight (Above): The low pressure system should be off to the south of us in the states at North Dakota and South Dakota border, the thing is this system will still affect us as the trough line north of it will allow a large swath of rain to sit and move over much of southern Manitoba tonight eventually going as far north as the north end of Lake Winnipeg. Overnight the low will move a bit more to the north resulting in the swath of rain to move over southwestern Manitoba. A general 15 to 25mm of rainfall is likely by the morning hours in the red river valley areas further north and west into the interlakes and portage la prairie can expect a general 5 to 10mm of rainfall. Areas from the international border up to just south of highway can expect 20 to 30mm of rainfall overnight. There’s a risk for thunderstorms in most areas extending as far moth as the interlake regions. Temperatures tonight will drop into the low single digits (2 to 5C) for a large area as cloud cover sits over the area. 

Saturday (Above): This is when the bulk of the rain will occur with this low pressure system, according to the weather models the total rainfall from this system on Saturday could exceed 15mm for a large section of the south. The RDPS is on the conservative side and is considering less than forecast, the NAM is suggesting that by Saturday evening a large area of the province will recieve 20-30mm of rain with as little as 20mm of rain in Brandon and western Manitoba as the rain only happens on Saturday morning, afternoon before pushing east during the evening. Portions of the red river valley and the pembina valley seeing upwards 20 to 40 mm of rain by Saturday evening.  Temperatures on Saturday will rise into the mid to high single digits and low teens (6 to 10C). 

Saturday Night (Above): By this time the system will move off further east resulting in the showers moving south and southeast on the back side of the low, there’s a chance for flurries in the western escarpment of Manitoba lakes into the southwest part of Manitoba generally 2-4cm. A majority of the rainfall accumulations will only be in the 5 to 10mm range, but this will just top the rainfall totals up to levels unfortunately seen last week. I’ll have the rainfall totals posted below after Sunday’s outlook. Temperatures on Saturday night will drop into the low to mid single digits (2 to 6C), the warmest in the red river valley areas. 

Sunday: A chance of flurries or showers are possible during the morning hours in the western red river valley into the interlakes. Drizzle or showers are possible during the afternoon, with only 5-10mm of rain possible during Sunday. Temperatures on Sunday will soar into the low teens in the extreme western end of Manitoba with areas further east seeing high temperatures in the mid to high single digits (3 to 9C).

Sunday Night: By this time the low should have moved east into Ontario, winds will shift to the northwest and there may be a chance for flurries overnight into Monday. Overnight low temperatures will drop well below normal with low temperatures dropping into the low to mid minus single digits (-1C to -5C). 

As for precipitation totals the weatherlogics map used from www.weatherlogics.com is predicting a large swath of the Red River Valley with 50 to 60mm of rain, in some areas and upwards of 35 to 40mm in the southeast and interlakes, up to Arborg, 20 to 35mm from Brandon to Carberry and points north from Brandon and points west 4mm to 20mm. The bulk of the rain will fall in the Pembina valley, interlakes, red River valley, to Kenora and Dryden in NorthWest Ontario as mentioned with 20 to 80mm of rain expected in the southern half of Manitoba. 

This is just an example of what my parents had to deal with last storm when there sump pump seized. 

  

 I’m saying this with all due respect to be honest I’m very tired of writing about these lows but I really do feel for the farmers and everyone impacted by the flooding. In my life I have never experienced so many storm systems like this in a row, from those clipper systems in the winter months to the crippling Colorado lows of April with this much water and snow. I sympathize with all of those who have been affected by flooding , who have either had lost/damaged property or farmland and for those who have been told to be on the lookout to evacuate. My parents even though I won’t name them, they have also had water damage to there basement with water up to there ankles, after there sump pump seized in the last storm (in st James Winnipeg). Thank Goodness they have insurance.  My thoughts and prayers go to those affected by flooding. 

Regardless I’m going to try to bring you better news, it looks like much of southern Manitoba will gradually begin to see warmer weather next week , with high temperatures only rising to the mid to high single digits for daytime highs next week Monday through Tuesday with lows in the low minus single digits. High Pressure and calm weather will bring temperatures to the low to mid teens (10 to 16C) by Wednesday with overnight lows staying in the mid to high minus single digits or even getting above 10C.
