Tuesday's Observations

Rain Rain go away! Oh well at least it held off and gave us a beautiful and sunny weekend! Obviously it is raining this morning here in Eau Claire. The temperature is currently 43.5 deg F with a windchill of 39 deg F. The dew point is 40.8 deg F creating a relative humidity in the air of 90%. This amount of moisture in the air explains why we currently have precipiation falling. The winds are from the northwest at 10mph. The barometer is at 997.8 mb which is much lower than the previous days. This indicates that we are in the middle of a low pressure system. The skies are 100% covered with nimbostratus clouds with a light to moderate drizzle of rain. This surface map from Unisys shows the perfect counter clockwise rotation of the low pressure system (the center is over the MN, IA, WI corners).
This map from the Weatehr channel shows the low pressure system and rainy weather that we are seeing in the midwest as well as the High pressure dome currently on the west coast. I predict that this High pressure dome will slowly make its way to the midwest providing some warmer weather by Thursday.
