Southern Manitoba has experienced a wild past 24 hours with wind gusts associated with a cold front exceeding 90 km an hour at times. As a result, there has been reports of downed trees and powerlines across the province. The weather into our weekend can be expected to be calmer and quieter as a ridge builds over the central United States. A more robust pattern for storm chances increase along with heat heading into next week. Find out how this transition will occur and the weather we can expect before all this unfolds in this weekends blog.
(Above:) Hot weather is likely on the day Friday with highs in the high 20’s and low 30’s.
Friday: Southern Manitoba can expect a hot day on the day Friday with high temperatures in the low 30s, especially along the American border and high 20s, areas in along the American border may soar past the 30C mark. Moisture levels however will be low as dew points will not be able to climb into the teens until the early evening. Sunny skies are expected for the day on Friday however there may be some local haze as smoke from wildfires filters in to the region. Should be less than on Wednesday. \
Friday night: a cold front will be moving into southern Manitoba during the overnight. Little in the way of cloud cover is expected the HRRR is showing a line of thunderstorms moving into western Manitoba during the overnight. However not all models are latching on to this idea, if severe storms move into western Manitoba during the overnight they will have the potential to produce marginal to large size hail with strong winds and heavy rain. However there is limited moisture which may inhibit the chances for any thunderstorms to develop, weather severe weather develops is still unknown at this point. General MUCape is expected to be between 800 to 1500 with dew point temperatures in the mid teens. If thunderstorms are able to develop ahead of the cold front there will be the potential for large hail damaging winds intense lightning and a small chance that some of these storms could rotate. Confidence on severe weather is low at this point however we will update you if there are any model changes throughout the day on Friday. Temperatures will likely drop into the high teens and low 20's, with areas in the southeast part of Manitoba the warmest.
Saturday: It generally drier day should occur on The day Saturday if there remains any convection in the morning should clear by the afternoon, sunny skies are likely on Saturday with high temperatures in the low to mid 20s in southwestern Manitoba and mid to high 20s in southeastern Manitoba. Smoke will begin to build back in to southern Manitoba on saturday evening, behind the front. This will be brief as another wave of southerly winds move in on Sunday. Saturday night, increasing cloud with some cooler temperatures are likely with lows in the mid teens are a possibility.
Sunday: Warmer weather is likely with a return of high temperatures in the low to mid 20's. Increasing cloud is possible on the day Sunday with some showers possible towards the later half of the day. Overnight more cloud is likely with lows in the low teens in the west and mid to high teens in the east.
The Week Ahead: Warmer weather is likely during the week with an increased chance for showers and thunderstorms as a heat dome sits off to our south and the storm track sits over our region. Temperatures in the low to mid 20's are likely with lows in the teens, some days especially earlier in the week may see temperatures in the high teens for highs and low teens for lows. Next week the moisture leftover from Hillary (Hurricane hitting southwest USA will start filling into the jet stream next week impacting us likely. I’ll have more details about that next blog on Monday.
