Thursday and Friday's Observation

Ok so yesterday was an interesting day for weather but yet again I was too busy to make it to the computer to blog. So here is a recap. As I was walking to school early in the morning the wind was coming from the east at around 12 mph hours. Half the sky was filled with cirrostartus clouds and the other half was filled with lower stratus clouds. (I caught a beautiful picture of the defined front that was present in the cloud formation). Then later in the day the wind had switched to the northeast indicating the the low pressure system that was moving into the region was going to pass to the south of Eau Claire. The temperatures were cooler all day and the skies remained 100% overcast for the entire day.

Today's temperature is also cooler at 45 deg F with a windchill at 35.2 deg F.  The dew point is at 23.2 deg F creating a relative humidity of 42%. The barometer is at 1017.7 mb. The wind is at 15 mph from the East. The skies are 100% covered with altostratus clouds. Therefore I predict that we will see rain or possibly snow within 18-20 hrs. The map from the Weather Channel shows that there is a clearly defined mid latitude cyclone (visible in a comma shaped pattern) in Kansas and Missouri. This is the same low that moved to the south in Thursday's observations. The occluded front (pink line) in the mid-latitude system means that the system is in its end stages and will be dying out in the near future.
