Nice Weather Expected to Continue, Becoming Unsettled For The Weekend

After a rainy weekend and a glorious start to the week, it is looking like the sunny and warm trend will continue for several days ahead as a ridge of high pressure starts building into the Eastern Prairies Including Manitoba. As a result we can expect to see temperatures in the mid to high 20's during the time period. Although we will see a very slight chance for some showers and thunderstorms today as an area of small low pressure slides through the area. Another area of low pressure is forecast to move in For Friday and Saturday bringing a chance for showers and thunderstorms once again.
An area of High Pressure is expected to gradually build over Manitoba in the coming days, it is not shown on the map though it is find in the big circle in Northern Manitoba.
There is a chance for a shower or thunderstorm over Southern Manitoba this afternoon as a trough moves southwards as it heads into North Western Ontario, the best chances will remain to the East through the Whiteshell regions and in SW Manitoba. Everything should organize and drift south and eastwards out of the province by evening hours.

Next on the headlines, it is looking like a fairly strong ridge of high pressure will continue to build into Northern Manitoba, and it is looking like it will strengthen to almost be at 1030 mb by tomorrow morning. The axis will be from The Red River Valley Northeast into Hudson Bay and James Bay. The system will ensure sunny and clear skies over the period of the next few days, limiting clouds only to fair weather cumulus and as well allow for a southerly flow to take place over the southern portion of the province. This would usually result in hot temperatures and high humidity but in this case it will provide less humidity and more normal temperatures. Instead of this high pressure system being created by a ridge, this is one that will be created by a trough of  cold air descending from the Arctic. The southerly flow that will develop over southern Manitoba will be a return flow of air out of the high pressure system  instead of being a warm moist flow from the Gulf of Mexic. Leaving our temperatures slow to climb as each day progresses and dewpoints only rising into the low to mid teens.

Friday Saturday will be another stormy few days as another low moves into the province,scattered thunderstorms and showers will both be possible on these days with accumulations nearing 5mm in showers and higher amounts of course in thunderstorms. Severe weather will be possible on Friday in Southern Manitoba as highlighted by The Prairie Arctic Storm Prediction Centre based in Winnipeg.

Next Week looks like it will continue to be nice with Temperatures in the high twenties along with lots of sunshine.
