Ever since the pattern changed their warm sectors have either missed us or occluded out. All we needed was 1 day of about 4/5 C with strong winds to eat away most of the snow... and we couldn't get it! This reverses the trend somewhat of recent Novembers where we were easily getting warm temps. In past winters we even had warm windy days in January even with 30 cm of snow on the ground.<BR/><BR/>Now we will see how cold it gets. With minimal to no snow cover.. we will not drop to -40 C. We would need an extensive and deep snow cover in place coupled with a very cold air mass (850 MB temps < -35 C)Danielhttps://www.blogger.com/profile/00949425441824069047noreply@blogger.comtag:blogger.com,1999:blog-33386160.post-50754054412946059632008-12-02T10:38:00.000-06:002008-12-02T10:38:00.000-06:00Hope you enjoyed that +1C this morning.. we may no...Hope you enjoyed that +1C this morning.. we may not be seeing temperatures like that for a long while!

Looks like Winnipeg and the RRV should get up to +1 or +2C this morning before the cold front moves through, shifting winds into the NW and dropping temperatures to -10C by the drive home.robhttps://www.blogger.com/profile/01577519556216420480noreply@blogger.comtag:blogger.com,1999:blog-33386160.post-73589843340920876802008-12-01T22:57:00.000-06:002008-12-01T22:57:00.000-06:00I hate to be the bearer of bad news, but it looks ...I hate to be the bearer of bad news, but it looks like this "mild winter" is about to come to an abrupt end. The models I have been watching for the past three months have been grossly underestimating low temperatures. Quite commonly 5 to 10 degree off of the actual, but to the BAD news....<BR/><BR/>They are currently showing (bearing in mind the underestimation of temperatures here) lows of -31 for late next week. This under a very strong 1052mb high pressure cell. Considering how much these temperatures have been wrong, I interpret this as a -35 to -40 low temperature in actual terms. Of course it is still a long way out, but a very unwelcome sight indeed. <BR/><BR/>Along with this cold air comes the likelihood of a green Christmas in some parts of Manitoba. This kind of cold will not support more than snow grains for precipitation, thus preventing heavy snowfall. Areas in the South-East, like Steinbach only have 4 to 5cm on the ground. I assume some areas have little to nothing.<BR/><BR/>So much for the good weather....Scotthttps://www.blogger.com/profile/10378918135776009197noreply@blogger.comtag:blogger.com,1999:blog-33386160.post-63479885803404142982008-12-01T19:27:00.000-06:002008-12-01T19:27:00.000-06:00I see that Environment Canada has finally switched...I see that Environment Canada has finally switched their radars over to "snow " mode as they had it in "rain" mode all last month.<BR/>Rob what would happen if they left it in "rain" mode all winter.<BR/>Will the radar not be able to pick up the snow as well???Anonymousnoreply@blogger.com
