NCEP NDFD snowfall forecast issued at 22z Monday, March 12, 2018.
This will be the 3rd Nor’easter in 11 days to affect the northeast U.S.
Goes-16 water vapor satellite image from Monday, March 12, 2018 — Another major Nor’easter getting ready to impact portions of the northeast U.S. through midweek. The surface low which was at ~990mb this evening is forecast to deepen to ~965mb on Tuesday as it lifts north across the western Atlantic.
18z NAM Nest model simulated wind gust forecast from this evening through Wednesday evening. A powerful Nor’easter will produce tropical storm force to hurricane force wind gusts and blizzard conditions in parts of the northeast U.S. on Tuesday.
Scattered clouds but still quite a bit of sunshine was seen over the Northland today with high temperatures near to about 5 degrees above average for the 12th of March with highs in the mid to upper 30s. It was a tad on the blustery side today with northwest winds in the 10 to 20 mph range with higher gusts. Upper level winds were still are out of the northwest today between a strong high to our west and a rapidly deepening surface low over the west Atlantic (just southeast of Virginia late this afternoon)
High pressure will be in control of our weather through midweek — Expect clear to partly cloudy skies for tonight and Tuesday and partly to perhaps mostly cloudy skies at times on Wednesday. Lake effect snow showers and flurries tonight and Tuesday along the South Shore of Lake Superior with the chilly air and north flow moving over Lake Superior otherwise dry weather in our area through Wednesday.
Lows tonight ranging from around zero to 20 above, highs Tuesday in the upper 20s to middle 30s so slightly cooler compared to Monday’s highs. Wednesday afternoon’s temperatures will be in the 30s to lower 40s.
Note: I don’t see any rain or snow affecting northeast Minnesota or northwest Wisconsin at least through Friday. The weather pattern might begin to turn a bit more active in our area starting around March 18-19 which could then persist at times for the rest of March. Whether or not we see snow or rain or a bit of both remains to be seen as that will come down to the tracks of each low pressure system that may or may not impact the Northland later this month.
