Journal 1-2: General Weather Observation
SNHU-SCI-207
I live in the Northeastern region of the United States in New Jersey. The green dot on the map
represents Hightstown, New Jersey. The forecast observations started on Thursday night and
lasted until Sunday night. Based on my personal observations Thursday morning clouds obscure
most of the sky, which means it is partly cloudy. About 12 o'clock, clouds cover most of the sky
with 10 mph winds. In the afternoon clouds continued covering the sky but the winds died down.
The chance of precipitation was 50% chance of rain. Low 41-degree temperature.
Observations and data show that precipitation events for Friday are the same with a 50% chance
of rain. Still windy with 5 mph winds but the temperature increased to 21 degrees. Precipitation
and wind patterns were similar between the two days. However, the cloud cover was minimal,
and temperatures were different. The following two days, the weather was clear, no cloud cover
or precipitation. Temperatures increased Saturday with a high of 68 degrees and a low around 46
degrees. Sunday is mostly sunny with a high near 73 degrees and a low of 52 degrees. The rest of
the coming week will be clear during the day and evening with a chance of precipitation between
40% and 30% chance. I do see patterns in the precipitation and slight changes in the temperature.
These are particularly common during springtime in the Northeastern states.
The data from the observations shows the current weather patterns and the readings from this
week allow us to analyze the forecasts more accurately. By looking at both of these together, we
can make connections between the current weather patterns and the forecasts, giving us a better
understanding of how the weather will change in the future. However, a change of the forecast
can change at any moment. As I analyzed the Extended forecast, I saw that there were some
changes in the forecast. Like today for example, that said tonight would be cloudy although I
only saw sun and increasing clouds. For me it looks like it is not going to rain but in the updated
forecast it says we will have a 60% chance of rain.
The increasing clouds could be because of water vapor in the atmosphere. In our textbook it
explains that water vapor, which is a variable gas, is the most abundant of the gases. The source
of water vapor is water evaporation on the Earth’s surface, but it decreases rapidly with altitude.
Most of the water is at an altitude of 5km or 3mi from the surface. Eventually this water
condenses and falls to the surface in the form of droplets (rain) or crystals (like snow). During
this time of year, it will rain in my area. But also, I learned that atmospheric pressure has a huge
impact on weather changes daily. Atmospheric pressure is one of the most fundamental weather
characteristics because of its role in producing wind. The air in the atmosphere tends to rise in
areas of low surface pressure and sink in zones of high pressure (Aguado and Burt). The rising
motions of the wind and air mass if favorable particularly when clouds form, which then
accumulate water vapor and eventually fall to the surface. Maps and satellite images help track
air masses and predict weather in a region. Looking forward to learning more about it. It’s very
interesting!
