Does this weather condition make sense?

Intro:

Francesca: As of this morning in Maine, there will be a cold front heading in from northern Canada which is part of the continental polar air mass. This will lower the temperature of the land it passes as it moves. We might see an increase in cumulonimbus clouds producing heavy precipitation later on around noon today, and possibly a thunderstorm as well. But further into this week you can say bye to the cold weather, due to a warm front heading our way. This is going to increase the relative humididty of the air, and raise the Dew Point



Francesca: The weather conditions around the United States are becoming quite severe. In southern texas, sitings have been shown that a tornado is sweeping through Dallas and destroying everything in its path! East of Texas, weather officals have spotted a near by hurricane making its way to the coast of Florida.



Cassaundra: There is a high pressure system over canada and parts of norhtern maine, causing strong winds in the low pressure system over new york. With the station's barometers reading 1012 for maine and 1001for new york, the isobars on this map give you an idea of were the low and high pressure systems are. The low pressure over new york has caused the majority of the state to be covered in a layer of stratus clouds. The opposite is ture about canada and maine; the effect of the high pressure has caused only a few cirrus clouds to cover the sky.



Cassaundra: The jet stream, which is currently over the northern United states, is predicted to shift south within the coming days.





Are there any problems with this? Thanks!!Does this weather condition make sense?
I will only look at the general science accuracy of this script and nothing else.



Paragraph one: No meteorological errors found.



Paragraph two: What are "sitings"? Do you mean "observations"???



Paragraph three: In the first sentence, "high pressure system" should be changed to "surface high pressure" and "causing strong winds in the low pressure system" to "causing strong winds near the low pressure system".



Paragraph four: No meteorological errors found.



Other than what I had noted, the science (weather conditions) in rest of the written script looks to be correct.



Again, I did not make any other corrections to this script like in grammar, spelling, or other errors that were not science related. Those errors, you will need to find and correct.
