Weather Observations 2/28

High level clouds this morning (stratocumulus).  Winds out of the East this morning, at about 10AM.  Shifting from to the South at midday into the afternoon hours.  Satellite images show cloud cover and high reflectivity in the clouds to the south and west of Eau Claire in states like the Dakotas, Iowa, and parts of Minnesota.  Here is a current conditions map from wunderground.com that I was able to capture using Hypersnap6.8. Temperature 33F at 1PM.
Serious low pressure is hovering over Colorado and Nebraska currently.  The warm front that can be seen moving northward through Oklahoma and Kansas is bring warmer, moister air from the Gulf and it is being sucked into this big low pressure system.  When this warm moist air and the cold air mix, precipitation generally occurs and at times it can be heavy if the right conditions exist. 

Also here is a upper air sounding from the Chanhassen Weather Station near Minneapolis/St. Paul, MN at 6am this morning.  This reading shows a fairly stable atmosphere with a surface temperature inversion.

Observed at 926 Menomonie Street Eau Claire, 54703
