Technically, windchill is not really significant if the wind speed is lighter than that. This morning, wind speeds are generally less than 10 km/h.. thankfully. <BR/><BR/>Tomorrow will be a different story.. another Arctic high building in from the north will produce northerly winds of 20-30 km/h (similar to yesterday) which will combine with -25 to -30C temperatures to produce extreme wind chills of -45 or so.

Leading arc of high clouds reaching from Virden to Swan River. <BR/><BR/>Temperatures tanking rapidly between Emerson and Grand Forks as the calm winds and ridge spread SE.. -35 C at the border and -33 C at Grand Forks wouldn't surprise me now. <BR/><BR/>The odds of seeing anything like -43 C in the RRV are extremely remote. 850 MB temps and 500-1000 MB thickness do not support record cold values. An exceptional inversion would have to form just near the surface. The best chance for -40 C will be over the ridge and swale terrain of SE Manitoba. The sandy soil and sheltered valleys allow for optimal radiational cooling.Danielhttps://www.blogger.com/profile/00949425441824069047noreply@blogger.comtag:blogger.com,1999:blog-33386160.post-22131865593989432722009-01-12T21:33:00.000-06:002009-01-12T21:33:00.000-06:00WHOA!According to SHAW channel 48-34 C temp-48 win...WHOA!<BR/>According to SHAW channel 48<BR/><BR/>-34 C temp<BR/>-48 windchill<BR/>around 9:20 p.mAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-33386160.post-23769834516726690812009-01-12T21:30:00.000-06:002009-01-12T21:30:00.000-06:00Carberry is down to a chilling -36.

At 03Z the forecast is for temperatures around -31C, and that is exactly what the actual conditions are (-30.8C). The model shows a constant cooling rate throughout the night. The RUC also shows temperatures between -40 and -43 for the RRV. Areas farther east will be slightly warmer, but not much (-37 to -40). Based on what the RUC forecasted in Saskatchewan earlier this winter I have a high level of confidence in its forecast.Scotthttps://www.blogger.com/profile/10378918135776009197noreply@blogger.comtag:blogger.com,1999:blog-33386160.post-12860754055914235562009-01-12T20:50:00.000-06:002009-01-12T20:50:00.000-06:00Very tricky forecast in terms of overnite lows ton...Very tricky forecast in terms of overnite lows tonite other than stating the obvious ... very cold. Arctic ridge line has built in to most of southern Manitoba already. Winds have died off very early this evening promoting strong radiative cooling as mentioned. Temperatures are running between -30 and -33 C outside Winnipeg with YWG up to -29 C in the past hour. <BR/><BR/>GFS trying to show main high south of the area by midnite with that light SW flow over us. However current surface analysis does not match up to well with GFS prog for 00Z. Main elongated ridge still well off to the NW.. and there are no SW wind barbs showing up. Have a feeling we might get stuck with NW flow for a bit longer than model suggests... but tought to say really. <BR/><BR/>The last fly in the ointment are those high clouds. Looking at 700 MB relative humidity from GFS... areas SW of a line from Brandon to Grand forks will be cloudy by dawn. Those areas may well dodge a bullet but it is not going to help Winnipeg and SE Manitoba it appears. <BR/><BR/>My guess for overnite lows:<BR/>Steinbach/Sprague: -38 C<BR/>Winnipeg (YWG): -35 C<BR/>Winnipeg city: -31 C<BR/>Emerson/Hallock: -33 C<BR/>Grand Forks: -30 C<BR/>Fargo: -27 C <BR/><BR/>Snow depth and water equivalent for the northern plains can be found on the main NWS site along the left hand side... observations --> snow cover. Then under Snow Information --> National analyses. I would love to see a map including both Canadian and American portions of the RRV in terms of snow cover and even total annual precip for 2008.Danielhttps://www.blogger.com/profile/00949425441824069047noreply@blogger.comtag:blogger.com,1999:blog-33386160.post-41089047559828747272009-01-12T20:44:00.000-06:002009-01-12T20:44:00.000-06:00Winnipeg Airport:@ 8:40 pm-32 temp-43 windchillWinnipeg Airport:@ 8:40 pm<BR/><BR/>-32 temp<BR/>-43 windchillAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-33386160.post-2392239881150140252009-01-12T19:43:00.000-06:002009-01-12T19:43:00.000-06:00Already -30 here, with -40 wind chill.
