:: When When When!?
Now we are starting to see the snow picture a little more clearly...current regime for our area just became a bit more interesting. Sfc low has developed over Spirit Lake, IA (attm) at about 1017mb, with a very well defined trough/stationary front extending northward along the MN/Dakota borders. Southward from this low extends the ever-present cold front that extends through the main-system stacked H70 and H30 low that is positioned over KMCI attm,
Very large rain shield has moved northward from the IA low, and has dropped between 1/3" and 1/2" over most areas of southern and central MN. NAM guidance from 12Z run has been right on the money for the progress of this system...and I have no probs going with it for the outlook. Main concern still remains the freezing point...and it is so very very very close in so many snapshots in the models, everything is going to have to be categorical...will update in the AM:
Tonight...Rain. 100% chc. Low 35. ESE wind 5-7 mph.
Sunday...Rain. 100% chc. High 42. S-SW wind 5-10 mph.
New Years Eve...Rain, changing to freezing rain, changing to snow. Freezing rain possible after 9pm. Snow Possible after midnight. Low 32. Snow accumulation of 1-3" possible. Wind SW 5-10 switching to NW 10-15 mph after midnight.
New Years Day...Periods of snow. High 32. Wind NW 10-13 mph. Low 28.
