The title is perfect. I am often under the weather and it has a big influence on my emotions. My moods is shifting from happy to sad thinking about all kind of things
Excellent write

Third line- reflects should be reflect.

I agree the title is perfect and fits so well the poem you wrote. I believe it's always easy to use negative emotions for weather. But you did it so well. The rain compared to tears is well used for the both hurt. The wind is whispering or it can be screaming. But you used the voices in your head. Which I believe silence all your other thoughts besides those negative ones. Puddles are the tears or rain which tells me you have been crying a lot. The thunder and lightning lines are my favorite lines you used. You used perfect imagery to show you are a mess and your heart beat is racing and striking your chest. As fast as lightning. Which tells me you are nervous and sad or even a panic attack. I enjoyed the last stanza as well because you are thinking while looking out the window. Imagining everything that could happen. Beautiful and unique write!

Weather Emotions,

^ The title got my attention.

I read this piece three times and based on that, I got the impression that this poem was written like we usually write them "spit and post" ( Maple's term) without editing.

I think it would be benefited if its edited though.

Lately she's been watching the weather
through the safety of her glass window;

-- I've been thinking about the first sentence, I feel a comma after 'lately' works best. I like the second line, though "glass" to me sounds redundant. Whenever I think of a window, I usually picture a glass. If on the other hand, I was told: " through the safety of her room's window" that would give me another perspective. Just adding some suggestions.

it seems to reflects how she feels deep down inside.
The rain seems to understand her tears,

The word "seems" is written too close that when I read this piece three times, it screamed directly to my ears with a buzzing that made me go 'ouch.' There could be another way to rewrite one of those lines so it won't have that effect.

the wind echoes like the voices in her head.

^ "echoes" when something echoes, its usually because the rooms are empty, so that gives me an insight to how your head was in that particular day, right? empty from everything else.

Puddles form throughout the streets in her mind,
and she often wonders which one will drown her.

^ I really like these lines.

Thunder bounces between the walls in her chest,
while lighting strikes at her heart.

^ it reminds me of the meowowhowling. lol Though I like these lines too. It has a dramatic effect for me.

The tornado traps her in endless spins
of her torturing memories.

^ "the" is used too sudden. The is an article but also an adjective that describes something in specific. "Like THE one. So "the" comes up too sudden for me. I have no recollection of a tornado being presented to me before other than the wind echoing, but that wasn't strong enough to introduce me to a tornado. So my suggestion would be to use "a" instead of "the" that way "a" would introduce me to some tornado. Not THE tornado. I don't know if that makes sense.

And she sits alone, by her bedroom window,
just gazing at the weather; the only thing
that seems to understand exactly how she feels .

Nice lines.

Overall, the idea of comparing the weather to emotions is not new. However, it's always enjoyable to see how people write it. And how each person comes up with a different visual for the readers.

Another thing, I noticed is that you used bedroom window... that could also go in the second line. "through the safetly of her bedroom window" unless you wanted the reader to interpret something with the "glass."? I would doubt that the repetition of bedroom window would not work. I think it would tie the poem. After all the setting is the bedroom. Well done.
