April 27

Yesterday was phenomenal, great weather, I went on a trip to the Ice Age Trail with Geography 304 so I forgot to post the weather. There was a light rain in the morning as predicted.
 you can see the juxtaposition of the nice sky and the storm cloud. This was caused by that dip in the jetstream we talked about last post.

This is a panorama of the rain cloud (the black on top is from the camera)

Today was another stunning day, some interesting clouds about, I am seeing some darker cumulus congestus clouds, altostratus, and cirrus clouds today.
Today's photo, as you can see, lots of different types of clouds, this is pointing to the west/south west. May be indicative of turbulent weather tomorrow night.

Temperature: 71°F (say what? I can dig it)
Dew point: 45°F
Humidity: 40%
Pressure: 1015.9mb (and dropping according to weatherbug)
Wind: W 7 mph
There are two low pressure domes to the north, the lower one is pushing warm air east, we are still feeling the effects of the high pressure system that has been prevalent yesterday. However starting tomorrow night that low pressure area will pass further east creating changing wind direction to come from the north and causing a drop in temperatures and precipitation next week.

 That circle in the middle under the dakotas is a high pressure system, it is causing a pressure ridge in our area, which explain the exceptionally nice weather we are having. Tomorrow night that will clear out and a lower pressure will result, causing rain and possibly snow.
There is a great deal of moisture to the south and west of Wisconsin. As the western moisture moves east,  it may dry up a little due to orographic lifting over the Rockies, the moisture to the south may move north.
