Wednesday, April 25

Today is supposed to get up to 50 degrees, which is nice, but not as nice as yesterday! I woke up and it looks like we have some stratus clouds blanketing the sky. we have winds coming from the east/southeast at about 10 mph. Because of this I expect that at some point today it will rain. After looking at barometric trends I noticed that the pressure has been pretty inconsistant, but is currently falling. I think that if this stays consistant that one of the times it starts falling we will see a little bit of precipitation.

The surface map shows that there a low pressure system just to our west that has two stationary fronts extending from it. Because of this I will expect this weather to hold consistant today until these stationary front develop. After this begins to move I predict that we will have precipitation while it passes and then our temperatures will drop because the cold front trailing the low pressure system will allow the arctic winds to hit us.

On the surface map you can also see that the isobars from the south are extending further north above the warm front extending from our low pressure system. This is because the moisture associated with a  system like this comes from the south and often will cause thunderstorms and rain just north of the warm front. This explains why our relative humidity is 80% today, as our air is thick with moisture from the Maritime Tropical air mass!

Also, I was curious to see how our atmospheric stability was incase we might be in for a thunderstorm today! But as it turns out, our atmosphere is stable and we will probably just receive precipitation.
