Cooler than Average weather continues

 Southern Manitoba and much of the region can expect a cooler than average weekend,, a persistent and stubborn arctic high pressure system will continue to draw in a northerly to northwesterly flow. Normally this time of the year we should be seeing a much warmer pattern. Is there any hope on the horizon, we’ll have a look and see if this temperature trend has any chance of ending anytime soon. 






An area of high pressure will move off into Ontario by Sunday evening. Should help to finally bring in a southerly flow. 

Friday: Much of southern Manitoba will be in the presence of sunny skies on Friday; a northwesterly flow aloft will inhibit temperatures from soaring to our normal day time high temperatures. All of southern sections of Manitoba will see highs in the low teens (10 to 14C), with temperatures over the lakes seeing low to mid single digits (3 to 7C). Heading into Friday night, a calm night is expected some light cloud is expected in areas of southwestern Manitoba however. Temperatures will drop into the low minus single digits (-1 to -3C) in areas of southwestern Manitoba with areas in the southeast staying at the 0C mark. Friday,, Winnipeg: Sunny high 12C. Brandon: Sunny High 12C. Dauphin: Sunny high 11C. Friday Night: Winnipeg: Clear . Low 1C. Brandon: Partly cloudy. Low 0C. Dauphin: Clear low -1C. 

Saturday: During the day Saturday a system with rain and snow will cross from south central Saskatchewan into North Dakota no rain will fall however, there appears that there might be some broken to partly cloudy skies for areas of extreme southwestern Manitoba. The extent of it should only travel as Far East as portage la prairie. Temperatures for the afternoon will rise into the low teens once again (10 to 14C) with the exception of the parklands where highs will stay in the high single digits (7 to 9C). Saturday Night much of the cloudcover that which was in the southwest will clear out and once again I’m honestly not a huge fan of these overnight lows they will drop below zero (-1 to -4C) for areas of the inter lakes and southwestern Manitoba, with the southeast staying above zero, (1 to 3C). Saturday. Winnipeg: Partly cloudy. High 11C. Brandon: Cloudy in the early afternoon, becoming partly cloudy late in the afternoon. High 11C. Dauphin: Sunny high 9C. Saturday Night: Winnipeg: Clear, low 1C. Brandon: Partly Cloudy, low 0C. Dauphin: Clear, low -1C. 

Sunday: Much of southern Manitoba will likely see similar conditions to Saturday, the area of high pressure that will be off in northern Manitoba will start moving south and east this will ultimately allow a northerly flow to take place. Im expecting some off and on clouds throughout the day. Temperatures for some areas of the inter lakes , eastern, and parklands regions of Manitoba will only sit around 10C (9-10C).  Elsewhere for the rest of the south expect high temperatures to rise into the low teens (10 to 12C). Heading into Sunday night I’m finally expecting that pesky high pressure system off in the north that’s been keeping our temperatures cool to finally move over our region into Monday morning. I expect clear skies overnight with partly cloudy skies by morning in the interlakes. Our overnight lows will drop below zero for the Manitoba lakes into the red river valley. (0 to -3C). Elsewhere overnight lows will drop from (1 to 2C). Sunday: Winnipeg: Sunny, high 10C. Brandon: Partly cloudy in the morning then Sunny. High 11C. Dauphin: Sunny high 9C. Sunday night: Winnipeg, clear low 0C. Brandon: Clear, low -1C. Dauphin. Clear low 0C. 

Heading into next week it appears that the area of high pressure that was causing our cooler than normal temperatures will move east into Ontario and the north eastern United States, this will ultimately give us a southerly flow with temperatures returning to seasonal values highs in the high teens to low 20’s, and overnight lows in the mid to high single digits. This would bring along a possibility of us seeing more low pressure systems with a chance that will bring us much-needed precipitation. It’s still a ways out but model trends need to start being a bit more consistent with this, in order for us to have more confidence. Hoping and praying we get that well needed moisture.
