As of 13:45 GMT (8:45 am CST) November 20, 2013 a large area of extremely cold air covers western Canada. This mass of Arctic temperatures, more typical of January, has started to move across the border into the northern Plains. Note on the map that the temperatures in the southern Prairie Provinces of Canada are -20F to -30F.
The following map shows the forecast total snowfall accumulation. This event will be moisture starved so snowfall amounts will be on the relatively light side.
The official forecast from the Omaha/Valley, NE, NWS office is:
- Thursday Rain likely, mainly after noon. Cloudy, with a temperature rising to near 37 by noon, then falling to around 32 during the remainder of the day. Breezy, with a north wind 11 to 21 mph, with gusts as high as 29 mph. Chance of precipitation is 70%. New precipitation amounts between a tenth and quarter of an inch possible.
- Thursday Night Snow. Low around 20. Blustery, with a north wind 16 to 21 mph, with gusts as high as 29 mph. Chance of precipitation is 90%. New snow accumulation of 1 to 3 inches possible.
Looking out through November 25-29 shows a high probability of colder than normal temperatures in our area and much of the lower 48 states.
The 6-10 day outlook shows a higher chance of drier than normal than wetter than normal so it doesn't look like we will have much snowfall during this anticipated cold spell.
