I awoke today to a rather neat-looking mackerel sky, which indicates shearing in the atmosphere and a change in the wind direction. According to the jet stream, we're currently located near the tail end of a ridge, which explains the shift in wind directions. To our west, there is a cold front that could bring precipitation later this evening.

The trough is apparent in the jet stream map below.

Earlier today I observed some cumulus humilis clouds that slowly evolved into cumulus congestus clouds, which lead me to believe that it might rain. Well, the rain never came. In addition, today was also a rather gusty day, which is most likely due to the rather intense low pressure dome to our north. In the charts below, one can observe the correlation between the change in wind speed and the change in pressure. As illustrated by the charts, the change in wind speed corresponds to the change in concavity of the pressure line, with wind speeds increasing most rapidly at the point inflection on the barometric chart. Essentially, this illustrates how gas moves from high pressure to low pressure. In this case, wind is being forced towards the center of the low pressure system, causing high winds from the West.

Temperature: 63 F
Wind: NNE at 5mph
Humidity: 44%
Pressure: 29.94 (rising slowly)

Well, today was another goregous day; it's too bad I had to spend most of it doing homework. Just a few minutes ago, I noticed a neat looking mackerel sky in the west. In addition, I noticed that the cloud layer seemed to be stratified into verticle slits. This could suggest some sheering in the atmosphere. Interestingly enough, Eau Claire is currently situated between a warm front and a cold front, which could explain the acloud pattern. It's quite possible that it could rain soon.

Well, according to the meta station on UWEC's website, it's still 19 degrees, so I couldn't rely on that today. Overall, it's been a gorgeous week of weather, and it didn't realize what negative implications it could have for the agricultural sector until today's class. The weather we're currently experiencing is due in part to our location near the tail end of mid-latitude cyclone. In the next few days, we could be seeing more rain brought on by incoming low pressure systems.

Temperature: 25.3 F
Wind: ENE at 3 mph
Humidity: 35%
Dew Point: 1.6 F
Pressure: 30.59 in Hg (rising slowly)

Well, today was a bit colder than it has been, partly because the jet stream brought some cold air in from the continental polar air mass. Also, the high pressure system that I mentioned yesterday made for a very clear day.

Current Conditions
Temperature: 30 F
Wind: 26 mph NW
Dew Point: 20 F

Relative Humidity: 58%

Earlier, I observed what appeared to be some cumulostratus clouds overhead. In addition, I took note of the strong winds coming out of the NW. Upon doing some brief research, I determined that these cloud and wind conditions most likely represent an incoming cold front. Since gas moves rapidly from high-pressure areas to low-pressure areas, the strong windspeeds are most likely the result of an influx of high pressure, which causing a mass exodus of tropospheric gases. The surface map below supports my assertions. As the map illustrates, there is, in fact, a cold front right near Eau Claire County. In addition, the gusty NW winds are likely the result of air flowing from the aforementioned high pressure dome to the low pressure systems in the South and in the East.

Current Conditions

Temperature: 48.7 F

Dew Point: 40.5 F 

Wind: 0mph ESE

Relative Humidity: 73%

Pressure: 29.63 in Hg (rising slowly) 

Well, today's weather was outstanding. Despite chilly temperatures in the early morning, today turned out to be one of the warmest days in a long while, thanks in part to the warm front that moved in around the mid afternoon. In class we observed some banded cirrostratus clouds and a faint south east wind, which indicate sheering in the atmosphere and an approaching low pressure system. We may, therefore, experience some precipitation at some point tomorrow. In the image below, you can clearly moisture in the west. When animated, this image shows a counterclockwise swirl within the moisture, indicating an approaching low pressure system. 

Current Conditions
Temperature: 27 F
Dew Point: 21.7 F
Wind: W at 11 mph
Humidity: 80%
Pressure: 27.91 in (rising)

	Right now, Eau Claire is experiencing some mild snow flurries and overcast skies, which is most likely the result of the recent low pressure system that is now to our east. As the high pressure system continues to approach, the skies will likely clear up. For tomorrow, I expect fair conditions and clear skies.
