Cold and slightly unsettled weekend Expected

 Much of southern sections of Manitoba has experienced a fairly warm fall that has featured temperatures in the mid to high teens the past few weeks. Some days during the past few days seeing highs close to 20C, in November that is highly unusual.

Over the weekend we can expect to see a low pressure system (above) on the day Saturday to move through bringing in a slightly warmer airmass. Temperatures on the day Saturday will soar into the mid to high single digits, later a low pressure system will move in bringing a swath of rain and snow. Areas from the parklands south can expect rainfall, with most snow happening north by the Swan River regions. Snow with rain mixed will then quickly move through the rest of the south after 6pm.  There’s a good chance that this will clear out by the late evening early overnight period. Saturday night cold weather will filter in with a good chance of cloud cover clearing out. Low temperatures will drop into the low single digits in the southeast and south central  with the areas in the southeast seeing lows in the low minus single digits. Sunday the low pressure system as mentioned will move into Ontario , behind it a cold air mass will move in bringing another round of snowfall into southern regions.

Most of the area will see amounts of 5 to 10cm, except areas in northern Manitoba where upwards of 20cm could fall in NW Manitoba. Temperatures on Sunday will rise into the low minus single digits in southern ‘Manitoba areas in the north interlakes will see highs in the low single digits. Also poor visibility and snow and blowing snow is likely to occur in western portions of Manitoba. Travel isn’t recommended. Sunday night will likely be the coldest with overnight low temperatures dropping into the high minus single digits and low minus teens in the western half of Manitoba, along border regions. Elsewhere expect lows between -4C and -9C. Windchills might be colder than -10C in some areas.  

The week ahead: Temperatures will remain cooler than we have seen lately, with the likelihood of most areas seeing highs in the low to mid minus single digits on Monday with a swath of snow coming up from the states along a warm front overnight into Tuesday, lows on Monday night will likely warm as a warmer air mass arrives. Lows will sit around the zero degrees to low minus single digits.  Another cool day will arrive on Tuesday with highs in the low single digits in south central, southeast and parts of the southwest seeing those temperatures. Areas elsewhere in the west will only see highs in the low minus single digits. There’s a good chance of more rain and snow just still have to wait for more model data to determine where the heaviest amounts will fall. There will be the possibility of thunderstorms as mentioned by Dan Riddle from NWS Grand Forks. Whether they happen will depend on how far that warmth moves. Regardless we have some interesting weather ahead for the coming week.
