Its Cold But The Semester Is Almost Over!

Temperature: 51
Real Feel: 51
Wind: NNE 11 mph 
Precipitation: 0%
Humidity: 41%

Because of a recent cold front, low pressure and a jet stream trough I predicted conditions to remain cool and cloudy. Unfortunately those factors leading to my prediction of another cold cloudy day were accurate. I also mentioned that I did not expect there to be a significant chance for any precipitation considering the cold temperatures along with a lack of water vapor, however I was not completely right in mentioning this as there was a brief light rain this morning.

Air Is Still Pretty Dry
Today has been another cold and miserable spring day. This morning started out with full overcast skies and a light but cold rain. Throughout the day cloud cover remained fairly consistent as the sun was only present for brief periods throughout the day. In addition to the clouds and the cold, contributed by yet another cold front that has come through from the north, a high pressure system also to the north is creating north eastern winds in Eau Claire. Even though winds have a slight eastern direction there is minimal amounts of water vapor considering the cold 50 degree temperatures so more precipitation for today is unlikely.

Another Cold Front and Some High Pressure
I am expecting that tomorrow will begin a pattern that will bring us back into spring conditions. With high pressure to the north, cloud cover will likely clear up and the sun will be more apparent for tomorrow. Also the jet stream appears to have shifted into a more zonal flow, taking Eau Claire out of that cold trough and may possibly position us within a ridge which will allow temperatures to increase. I still do not expect a great chance for rain tomorrow as long as the air continues to remain fairly dry.
