Temperatures

Very cold conditions should persist all week, except that with our snow event on Thursday we may get up to 10°F.  Otherwise, highs should be in the single digits below or above zero through next Sunday, with tonight and next weekend likely having double digit negative lows.   Temperatures are expected to moderate to more near average next week (teens and 20s for highs, single digits for lows).

Precipitation

The only measurable precipitation for the Twin Cities through next Sunday is the snow expected to start around 3 AM Thursday and end around 6 PM Thursday.  Accumulation rates will be low, and the metro area should expect 2-3 inches of very dry, powdery snow over that period.  Winds will be light to moderate through the event and just after, so there should not be major issues with blowing/drifting snow.

Another light snow system will slide to the SW on Minnesota on Saturday, and behind that on Sunday, cold air will be reinforced, probably making next Sunday the coldest day of the season so far, but only a few degrees colder than yesterday.

Longer range, we may get some light accumulations of snow from clipper systems later next week.  About 12-14 days out, the model finally starts to turn the Jetstream from the southwest, allowing in some Gulf moisture and the possibility of heavier snows for our region.  The GFS model has been really poor with trends beyond a week this year, so we’ll have to wait for later to see if the pattern shift will really happen.
