Sun disappears for long weekend

Well.. bad timing, but today is the third day in a row of cloudy skies and local shower activity over the Red River valley and SE MB.. all due to convection over the northern Plains that has spilled over into southern MB. Rainfall has been minimal in the Winnipeg area, but persistent cloud and temperatures in the low 20s has made this last long weekend of summer not very summerlike. It looks like summer heat just can't get established this year over the southern Prairies as the jet stream remains stalled over the northern Plains.. with time running out for it to shift any further north.
