Colorado low system to impact southern Manitoba for Thanksgiving Weekend

 Hello folks I am back after not being able to write blogs over the last few months. It has been an interesting summer with sleeper setups, tornado events coming out of nowhere. Forecasts that were supposed to deliver potential for tornado events that never happened, there was concerns that SW MB one day this summer would have had dangerous storms. And this month flash flooding occcuring in Steinbach overnight with 125mm of rain in one night. And just 2 weeks ago a storm that we weren’t completely expecting formed over southern Manitoba SW of Winnipeg which turned into a strong storm complex that lasted well into NW Ontario . I will have a blog reviewing this summer coming up in the next few weeks. 

(Forecast wind speeds in southern Manitoba during the night into Monday) Potential exists for damaging winds on the Manitoba lakes. 

Anyways the Colorado low that has developed over the southern sections of the SW United States is moving up into southern Manitoba, southern Manitoba's story will be rain and wind. Areas of Northern Manitoba will be experiencing snow. As the system approaches a broad swath of rain will be moving into southeastern sections of Manitoba during the overnight time frame into Sunday morning. There will be a risk for a couple of rumbles of Thunder but the mean weather occurrence overnight will be mainly rain showers persisting into the morning hours. temperatures during the overnight time frame will be mainly in the low teens. 

On Sunday  as the Colorado low moves into the central region of the province, rain will be moving into central western Manitoba and the parklands region of western Manitoba during the afternoon. Some of it might be thunderstorms as it moves into the interlakes by late afternoon. There will be a line of showers and potential weak thundershowers developing by the late afternoon in southern Manitoba as the cold front moves through. Temperatures will rise into the mid to high teens in areas of the south, up to the interlakes. Rainfall totals of 25 to 50mm are possible in the parklands where Rainfall warnings are in place. 

Sunday night winds will increase over a large portion of southern Manitoba with gusts continuing to reach 90 to 95km an hour in areas of the interlakes further south gusts from 60 to 80 are possible for a large section of southern sections of the province. there is concerns that areas of the central interlakes up into far northern sections of Lake Winnipeg and Lake Manitoba may see wind gusts up to 100km an hour or higher. Temperatures for the evening will drop into the low single digits. a majority of southern Manitoba will see winds from 50 to 60km an hour with gusts up to 90km an hour during the overnight time frame we will keep you updated on the weather centre of Manitoba about any alerts that get posted in regards to the winds. There also will be a area of snow that will develop in areas that see rain in central Manitoba on sunday night. This will not impact any parts of southern Manitoba. The good news is that the snow that does fall in this area should melt. Areas from Melita northeast into Swan River will see this as it moves northeast into areas of the far northern interlakes. 

Some unfortunate news however to start the week temperatures will likely only reach the mid to high single digits, during the day on Monday and overnight low temperatures to start the week will drop into the upper minus single digits which is literally the warmest that we could go for overnight lows. Upper single digits are usually warmer lower single digits are usually colder.. A return to more normal temperatures are likely by the middle to later half of the week .
