Possible storm next week

Possible system coming in next week

1.While there remains considerable uncertainty regarding the storm next week, of the many weather scenarios possible, the following three are worth noting:

a.*Most Likely Scenario:* Rain switching to snow Wednesday for southern MB, Slight threat of freezing rain over southern Manitoba late Tuesday into Wednesday. Accumulating snow over northern Manitoba Tuesday, *up to 30 cm*. Snow Wednesday into Thursday for western Manitoba (5-15 cm). Strong winds from the south beginning Wednesday, gusts up to 60 km/h over much of Manitoba.

b.*Most Impactful Scenario:* Ice accretion on below freezing surfaces due to steady freezing rain late Tuesday into Wednesday. Up to 40 cm of snow over central portions of the province (Including Norway house), rain switching to snow across southern Manitoba. strong winds from the northwest up to 70 km/h on Wednesday across much of Manitoba.

c.*Least Impactful Scenario:* The most impactful weather occurs in Saskatchewan, or south of the border. Rain or flurries for western portions of the province with low accumulations. Winds remain below 50 km/h.

2.Potential impacts:

a.Difficult winter travel conditions, especially over northern and central portions of the province due to reduced visibility in heavy falling and blowing snow.

   2. Surfaces such as highways, roads, walkways, and parking lots may
      become difficult to navigate due to rain or drizzle switching to
      snow
   3. Surfaces at temperatures below zero may develop a slight ice
      accretion due to slight threat of freezing rain

3. *An update will be sent Monday, March 30 with the latest available
  information. This update could be an email or WebEx meeting
  invitation, depending on how impactful the weather forecast is at
  that time. *
