Forecast surface map for Wednesday, November 15, 2017
18z NAM Nest model radar simulation starting at 6 PM today, ending at 6 PM Wednesday. Rain shows up in green; Snow in blue.
Note: Mostly light rain and drizzle across the Northland tonight followed by some flurries and snow showers for Wednesday as colder air moves into the area. Precipitation amounts will remain on the light side, with possibly a dusting of snow Wednesday in parts of the area with a few inches of snow possible along the South Shore of Lake Superior in northwest Wisconsin.
Low pressure and a cold front were moving into the upper Midwest late this afternoon. A mild and humid southerly flow is occurring ahead of this system with widespread low clouds along with areas of fog and drizzle, expect these conditions to persist tonight while some light rain also develops as forcing increases a bit with the approach of the surface low and cold front. It’ll be a mild night in most of the Northland with lows in the 20s in northern Minnesota to the 30s in eastern Minnesota and northwest Wisconsin.
Blustery and cooler conditions for Wednesday as low pressure exits to the east with strong cold air advection taking place behind this low with 850mb temperatures of +4 to +8C late this afternoon dropping to -5 to -10C on Wednesday. Highs Wednesday will hold fairly steady or fall a bit in some locations with temperatures ranging from the mid 20s to mid 30s while northwest winds gust over 25 mph. Scattered snow showers and flurries are expected as well on Wednesday with a dusting of accumulation in some areas, perhaps a little more in the snowbelt region of northwest Wisconsin.
Winds will shift to the east on Thursday, and with lingering cold air in place, some lake effect snow showers could affect the North Shore of Lake Superior but accumulations look very light, maybe a half inch or so at most. Highs Thursday on the cool side with temperatures ranging from 20 to around 30 degrees.
Note: A new low pressure system moves across the region on Friday bringing some light rain or light snow to the Northland but this shouldn’t be a major storm the way it looks now. In fact a lot of the precip that falls may be in the form of rain with surface temperatures near or a few degrees above the freezing mark!
Note: Through 5 PM today, the high temperature at the Duluth Airport was 36 degrees which is the normal high temperature for November 14 — So the wait continues for the first above normal high temperature, the streak is at 18 days. There is a chance that the high temperature climbs above 36 degrees this evening, if not will have to wait until Friday for the next chance at an above normal high temperature.
