Rain Tonight; Warming Up

The remnant snow from mid week's storm will melt away this weekend as rain and warm temperatures return...

For today, clouds will thicken this afternoon ahead of a clipper system. Although we should reach mid single digits for a high, a very strong south wind will ruin the day. Winds will be sustained up to 50 km/h at times and gusts as high as 60-70 km/h. Rain with the clipper system will begin late this evening and end later in the overnight hours. 4-8 mm looks likely. Note that this system could even bring some weak thunderstorm activity to western North Dakota and southeastern Saskatchewan this afternoon and evening. However, thunder is not expected in Manitoba.

Skies will clear tomorrow morning, giving way to a nice sunny day. Unfortunately, strong northwest winds will somewhat ruin the day again. We should manage to reach mid to high single digits.

A weak system could bring some light showers on Monday. Nonetheless, it looks very mild Monday and Tuesday with highs in the low teens not out of the question if we can get enough sunshine.

Another system is expected for Wednesday-Thursday. There is still some disagreement on precipitation amounts and type. Any precipitation that falls on Wednesday so far looks to be rain as temperatures will be quite mild. Transitioning to snow may occur Wednesday night. Will update in the comments below as things become more certain. One thing's for sure, we will be cooling down again behind the system for late next week.

Update on Storm System

For today, we'll remain cloudy in Winnipeg and the RRV with drizzle and light showers at times. Generally mild as well with highs in the mid single digits this afternoon and evening.

Rain is expected to begin sometime this evening with light rain continuing into the overnight hours. Rain should transition to snow later in the overnight hours probably sometime between 2 and 5 am. In total, close to 5 mm of rain looks possible before switching over to snow, but this amount will depend highly on how early the switchover occurs.

The worst of the snow looks to be tomorrow morning. Snow may be quite heavy at times with significantly reduced visibility at times. Blustery northerly winds are expected to begin in the early morning as well with sustained winds of 50 and gusts to 70 km/h or more possible through the morning and afternoon. This will make for a very unpleasant day. The heavy wet snow combined with the strong winds could cause some localized power outages. Snow should end by the afternoon. In total, 5-10 cm of snow is expected for Winnipeg. Can't rule out a bit more if rain transitions to snow earlier than expected or if the snow is even heavier than expected.

Sunny, but cold for Thursday with highs in the -7°C to -4°C range. Chilly but a bit milder on Friday. So far, warmer conditions are forecast to return by the weekend and early next week which will allow melting of the new snow.
