Forecast Discussion for Northeast Minnesota and Northwest Wisconsin

Today's Weather:

Low pressure of 1002mb in Northern Arkansas with high pressure of 1040mb in Eastern Alberta Province late This Afternoon has opened up the flood gates for another round of arctic air as northerly winds setup between the low and high.  Temperatures This Afternoon were only in the single digits below to single digits above zero from Northern Minnesota west to North Dakota while 20s and even some lower 30s continued in Northwest Wisconsin.  Partly to mostly sunny skies were found across our area Today with winds out of the northwest under 20 mph.

Today's Upper Level Analysis:

An energetic pattern will persist through early next week and beyond...Water vapor satellite imagery shows one strong system lifting quickly toward the E/NE from the Central Plains while the next one churns slowly south through the Pacific Northwest.  The transition season (winter to spring) is upon us with huge temperature extremes Today which ranged from -3 at Minot, North Dakota to 77 at Dallas, Texas with 80s and even some lower 90s showing up This Afternoon in Southern Texas!  A powerful jet stream >130 knots covered the Great Lakes This Afternoon and also over portions of California, Southern Oregon, and Northern Nevada per RUC model analysis.

Tonight through Friday Night:

Strong high pressure will build southeast into the Northern Plains and Upper Midwest during this period while a deepening low heads quickly northeast from Arkansas to the Northeast U.S.  Partly-mostly cloudy skies will occur in Northern Minnesota and Northwest Wisconsin with the potential for a few snow flurries at times.  Lows Tonight and Friday Night will be in the single digits below to above zero with teens below zero and perhaps even some 20s below possible in Northern Minnesota.  Winds will be out of the north or west under 20 mph through this period.

Extended Forecast:

Could see some snow flurries at times this weekend into early next week, but no major storms are expected for our local area.  There will be another strong storm that lifts northeast out of the Central Plains Sunday-Monday, but the snow and rain associated with that storm will remain to our south/east.  High temperatures will be in the single digits and teens on Saturday with lows Saturday Night in the single digits below to around 10 above zero.  Highs on Sunday will modify (closer to average) with highs generally in the 20s with lows Sunday Night in the teens.
