Today in weather history
In Winnipeg, the cold front pushed through by 2 am that morning, sending temperatures of +4 to below freezing. By 6 am, the temperature was down to -8C and snow started to fall with winds increasing from the northwest. By 10 am, visibilities were down to 400 metres in snow and blowing snow, and temperatures had dropped even further to a record cold -13C. From noon to 4 pm, NW winds of 60 gusting over 80 km/h were giving blizzard conditions with visibilities down to 200 m at best. Temperatures were exceptionally cold, rising to only -11c by 4 pm (some 25 degrees colder than the day before) with windchills of -25 or lower. By 6 pm the blizzard was lifting, with skies clearing by 8 pm.
What a day that must have been! After hitting 15C on the 27th, much of southern MB would be hit with a severe blizzard the following day with almost January like weather. Wind gusts up to 87 km/h were reported in Winnipeg that day, with 100-105 km/h gusts around Portage La Prairie. The afternoon high of -8.3C in Winnipeg is the coldest ever for so late in the year, and is unequaled for its late season severity. I wonder what the forecast was calling for back then, and how did residents cope with such a drastic change in the weather?

Messy mix for the Thursday morning commute
Snow accumulations with this system will be highly dependent on elevation and the position of the rain/snow line.. but at this point, it appears areas north and west of Winnipeg will see around 10 cm of snow overnight with up to 20 cm possible over higher elevations west of the Red River valley. Areas south and east of Winnipeg will see more rain at first before the changeover to snow, so snow amounts in these areas will only be in the coating to 5 cm range. Here in Winnipeg, snow amounts will be a tough call since we'll be right on the rain/snow line much of tonight, but as a first guess, 5 to 10 cm are possible by midday Thursday, although some of that will melt initially due to the warm ground. Note that this system has the potential for heavy precipitation rates due to elevated convection, thus snow or freezing rain could be heavy at times overnight into Thursday morning. In areas that are cold enough for snow, this will mean very poor visibilities in heavy snow, with snowfall rates of 2 to 3 cm/hr possible at times. All in all, a messy commute to work and school Thursday.. be prepared for anything!

Format changes to Rob's Obs
Hopefully you find these changes an improvement to the site, especially for site navigation. Comments welcome. I've noticed the new drop down menu has a little time lag before it downloads (don't know why), so be patient for it.
