Thursday and Friday's Observations

Yesterday was around 28 deg F with a sun around midday and then a blanket of stratus clouds across the late afternoon sky. There was a northwest wind at around 5 mph. Eau Claire was in a high pressure system.

Today the temperature is 12.4 deg F with the wind chill at -.2 deg F making it quick different from yesterday's warmth. The dew point is at -2.4 deg F. Relative humidity is at 51%. there is a 6 mph wind coming from the West.The barometer is at 1023.8 mb. The sky is fairly clear with a few wispy cirrus clouds scattered throughout the sky. this explains the colder temperatures since the clouds are not keeping our warmth in the lower troposphere. This picture from ACCU weather shows that (similar to yesterday) Eau Claire, WI remains in the High Pressure system.

I forecast that tomorrow will be colder as the jet stream (shown below from Intellicast) continues to allow winds from the north and Canada to spill into the Midwest.
