* POSITION...At 800 pm CST...0100 UTC...the center of winter storm Andrea was located near laditude 91.3 West and
longitude 44.5 North, or about 50 miles north of Lacrosse Wisconsin.
* MOVEMENT...Andrea is moving generally north at 45 MPH/ 72.4 K/HR.
* MAXIMUM SUSTAINED WINDS...are near 31 MPH/ 49.8 K/HR...with higher gusts.
* MINIMUM CENTRAL PRESSURE...was 997 millibars, or 29.44 inches. Weakening is forecast to continue overnight.
Despite ongoing shear aloft, strong drier air punching northeast into the center is taking it's toll on Andrea. 88D and satellite
data affirms that the center of circulation, which is estimated to be north of Lacrosse, has become partially exposed to the
east and south. However, deformation zone precipitation continues across much of northern Minnesota into far northwest
Wisconsin, where moderate to occasionally heavy snowfall is occuring. Another 4 to 8 inches is still expected in those areas
overnight. Elsewhere, owing to the dry slotting, the precipitation has ended, or is of a drizzle nature.
IMPACTS ON LAND:
* SUSTAINED WINDS...of 15 to 30 mph mainly in open rural locations will persist across MN causing blowing and drifting.
* SNOWFALL ACCUMULATION...from roughly 4 inches across central to 8 inches over northeast MN into northwest WI.
* GROUND TRAVEL DELAYS...Roads across northern and central MN range from ice and snow covered and slippery to slippery
stretches. Elsewhere, no ground travel delays were reported.
* AIR TRAVEL DELAYS...None reported at this time.
The next complete advisory is scheduled for 700 AM CST.
