Thursday's Observation

Hey all! So there will most likely be more updates coming by the beginning of next week I hope to have added some data to the analysis page by Monday.

Anyways for today's depressing weather... Today I awoke to some large wet snowfall. Throguhout the day the snow stopped however the cold wet feeling remained. As for the temperature... it is currently 42.3 deg F with a windchill of 38.7 deg F. The dew point is at 37 deg F creating a relative humidity of 82% (hence the precipitation).  The winds earlier were from the Northwest but are now from the southwest at 8mph meaning that a high pressure dome is beginning to move into the region. The barometer is a 1012.0 which has been slowly rising throughout the day (also suggesting the higher pressure). The skies have been 100% covered with either nimbostratus or stratus clouds all day. This map below from Intellicast shows that there has been a slight trough in the jet stream causing some polar air to move into the region.
This map from the Weather Channel confirms the high pressure dome moving in.
Most people are predicting clear blue skies and some warming temperatures provided by the clockwise rotation of the high pressure dome. However as I see the small trough in the jet stream and I see the cold low pressure system over the northern rockies. I predict that here in the upper midwest we will see yet another mid latitiude cyclone bringing cold wet weather by Saturday morning.
