Well, it was kind of a crappy day today, mostly overcast and cold. Earlier today, we received a small amount of precipitation, and with the low pressure system moving east and away from the Rockies, it appears as if we might get some more precipitation within the next day or two. Doppler radar is showing some intense storms to our south. I found a link somewhere that depicted the strong likelihood of tornadoes in the central united states, but I can no longer find it. Either way, there should be some interesting weather within the next few days.

Well, it was pretty chilly biking to school today. As you can see from the maps below, we're currently situated in a unique position. Right no we're near the center of a massive high pressure system that brought cold weather from the continental polar air mass. Hopefully the low pressure system in the west will work it's way towards us and usher in some more moderate temperatures. 

Current Conditions

Temperature: 48.2 F

Relative Humidity: 46%

Dew Point: 28.4 F 

Wind: ESE at 3 mph

Pressure: 30.14 in Hg (rising slowly) 

As you can see from map below, the jet stream ushered in a lot of cold air from the continental polar air mass, making for a semi-chilly afternoon. At the same time, high pressure came in over the region and cleared up the skies. The map below shows a cold front in the west. In conjunction with the moisture demonstrated by the last map, it looks like we could get some precipitation within the next day or two.

Temperature: 48.9 F
Relative Humidity: 51%
Dew Point: 31.5 F
Wind: N at 0 mph
Pressure: 30.02 in Hg (Rising slowly)

Well, I'm happy to say that yesterday's prediction proved correct.  As you can see, the low pressure system that produced last night's thunder storm is now to our southwest. Earlier today I noticed some stratus clouds and some stratocumulus cloud cover. For tomorrow, I expect slightly warmer temperatures with sunny skies. As the jet stream map demonstrates, we should be receiving an influx of warm air from the continental tropical air mass.

Current Conditions
Temperature: 54.3 F
Relative Humidity: 51%
Dew Point: 36.7 F
Wind: ESE at 12 mph
Pressure: 28.91 in Hg (steady)

While walking to class today, I observed some altocumulus clouds with some congestion. Given the wind direction, we might expect precipitation within the next 15-20 hours, so possibly much later tonight. Regardless, we'll most certainly experience overcast conditions as the low pressure system moves in from the west.

Also, the jet stream is going ape shit today.   

Current Conditions
Temperature: 45.1 F
Relative Humidity: 56%
Dew Point: 30.4 F
Wind: SE at 14 mph
Pressure: 30.08 in Hg and Falling Slowly


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.

Current Conditions
Temperature: 63F 
Wind: W at 20 mph 
Humidity: 47% 
Pressure: 29.64 in Hg and Rising Rapidly  


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.
