Current Conditions
Temperature: 52.9 (F)
Dew Point: 49.1 (F)
Relative Humidity: 87%
Wind: 0 mph from North East
Pressure: 29.87 in Hg (rising slowly)

Well, today was kind of a lackluster day. Honestly, I sat in the lab for the vast majority of the day, but when I did go outside, I noticed that temperatures were a little brisk. This is most lkely due to the winds out of the north and the unique position of the jet stream. All of this, is brining in cold air from the continential polar air mass. Today was also rather cloudy, but conditions should clear up as soon as the high pressure system rolls in.  As the map below illustrates, the east coast is recieving a fair amount of precipitation as the massive cold front makes its way east. For tomorrow, I predict temperature conditions, but it should be a much clearer day.

Current Conditions 
Temperature: 57.6 (F)
Dew Point: 56.3 (F)
Wind: 4 mph from East
Pressure: 29.96 in Hg (steady)
Relative Humidity: 96%

Well, I was awoken today by the storm that rolled in, which is kind of sad because the storm didn't roll in until just past 4 o'clock. This storm signaled the low pressure system that came in. The rest of the day was cloudy and humid, and it appears as if we may get another round of precipitation later tonight or early next morning. For Monday, the high pressure system should bring in clear and sunny skies. As you can see, we're situated on a ridge of the jet stream, so we should be getting some warm, moist air from the maritime tropical air mass. The next few days might be a little warm and muggy.

Current Conditions
Temperature: 79.5 (F)
Relative Humidity: 36%
Dew Point: 50.4 (F)
Wind: 6 mph from the W
Pressure: 29.72 in Hg (steady)

Well, there were some storms last night, but Eau Claire didn't get hit nearly as bad as Minneapolis. Yesterday's prediction was, therefore, only partially correct. Today, was a beautiful warm, sunny day. The strong south wind brought in some warmer air from the continental tropical and maritime tropical air masses. Earlier today there appeared to be a mid-latitude cyclone situated over Wisconsin, but it seems to have fizzled out. Despite the large inflow of air from the continental tropical and maritime tropical air masses,we're really not seeing as much moisture in the region as I would have expected. For tomorrow, I predict similar temperatures (possibly a little warmer). I also believe we will be getting some rain within the next 12-42 hours.

Current Conditions
Temperature: 57 (F)
Dew Point: 48.7 (F)
Wind: ESE at 5 mph
Pressure: 29.8 in Hg (falling slowly)
Relative Humditiy: 74%

As you can see from the images below, it appears that our area is in for some severe weather. Strong southernly winds are brining in a lot of moisture from the maritime tropical airmasses, causing warm weather and potentially severe conditions.
With the weather sounding below, we can see that there are conditionally unstable conditions in Minneapolis right now. Ultimately, these conditions might cause convection and eventually unleash severe weather in our region. If a deep trough develops in the jet stream, we may see more severe weather of the next couple days.

Current Conditions
Temperature: 54.3 F
Humidity: 26%
Dew Point: 20.1 F
Wind: E at 6 mph
Pressure: 30.06 in Hg (steady)

Well, we experienced some pretty solid weather today. For most of today was pretty sunny, most likely because of the high pressure system. Later I observed a mackerel sky, which indicates shearing in the atmosphere and the incoming high pressure system. As you can see, there's a mid-latitude cyclone over Kansas. For tomorrow, I predict some cloudy weather with a good possibility of precipitation.

Current Conditions
Temperature: 58.6 F
Dew Point: 47.3 F
Relative Humidity: 66%
Wind: 4 mph from ESE
Pressure: 29.62 (steady)

Well, today was kind of a shoddy day. The low pressure system moved in and brought cloudy weather to the area. I'm glad to say that I correctly predicted the precipitation we experienced late last night/early this morning. For tomorrow, it appears as if an incoming high pressure system will bring sunny skies.

Current Conditions 
Temperature: 59 F
Relative Humidity: 30%
Dew Point: 27.5 F
Wind: 11 mph from ESE
Pressure: 29.62 in Hg (Rising Slowly)

Today was a beautiful day. A strong south west wind brought warmer temperatures. Recently, the wind has shifted directions, which could be due to the front moving in.If the warm portion of this front makes its way towards Eau Claire, we could see precipitation tomorrow. As you can see from the vapor map, there's a fair amount of precipitation to the immediate east of the Rocky Mountains.

Current Conditions
Temperature: 47 F
Dew Point: 26 F
Humidity: 44%
Wind: 5 mph from NE
Pressure: 30.03 in Hg (steady)

Well, I'm currently situated in Milwaukee, so I'll give a brief rundown of the conditions here. Overall, it's a pretty nice day, perfect for outdoor activities. It looks like we'll see some colder weather after that cold front makes its way east.

As you can see, there's a there's a pretty obvious mid-latitude cyclone located just northwest of Minneapolis, which I'm assuming is causing some pretty cloudy and rainy weather in Eau Claire. In Milwaukee, we're quite unaffected by this cyclone. The weather is actually pretty clear, and the wind direction is different.

Current Conditions
Temperature: 64.8 F
Humidity: 45%
Dew Point: 43 F
Wind: WSW 17 mph
Pressure: 29.85 in Hg (Steady)

Well, the low pressure system that moved in could be observed by the overcast conditions. I'm happy to say that yesterday's prediction came true; we did, in fact, experience precipitation--not the thunderstorms I was hoping for, though. Right now, I assume that it will warm up as soon as the cold front passes through. Judging from the jet stream pattern and the strong WSW wind, we can expect warmer temperatures tomorrow, with similar cloud patterns. We may also expect some precipitation tomorrow, too.

Current Conditions
Temperature: 43.5 F
Dew Point: 28.9 F
Humidity: 56%
Pressure: 30.32 in Hg (steady)
Wind: SSW at 6 mph
Cloud Coverage: Partially Cloudy (Cumulus and Cumulus Humilis)

Well, as predicted on Sunday's blog post, the weather did take a turn for the worse. A radical jet stream brought some cold air from the maritime polar air mass, and we were left with cold and wet weather. Recently, south winds have brought in more moderate temperatures. Given the observed cloud coverage and wind direction, we might expect precipitation--possibly even thunderstorms--later tonight or early tomorrow mourning. Honestly, I find stormy weather exciting to observe, so I'm hoping for some thunder and lightening. The map below indicates an incoming low pressure system and warm front, which further supports my prediction for stormy weather. In time, conditions may be right for convection.

Current Conditions
Temperature: 43.9 F
Dew Point: 28.2 F
Wind: SE at 6 mph
Humidity: 54%
Pressure: 30.11 in Hg (falling slowly)


Well, the forecasters are predicting storms for the Eau Claire area. In fact, some weather alerts warned of 50 mph wind gusts, hail, and potential tornado.  Thus far, I haven't seen any of that, but the weather sounding below does indicate unstable conditions. The KI reading of 30 indicates a moderate potential for convection, and the LI index indicates very unstable conditions. Apart from the severe weather risks, it was a gorgeous weekend, for a strong south wind lead to beautiful warm weather. These conditions will not last, however. It appears that the jet stream will bring in cold air from the continental polar air mass. We might encounter snow/sleet in the next 24-48 hours.
