Rain

When I see って like that before a noun I think of it as "kind of".

寒くて、悲しいって感じ = "A kind of cold, sad feeling"

I don't know if its necessarily polite/formal 'cause its used instead of と in slang speech like "キレイって思う"

晴れ「はれ・hare」clear weather/sunny day (I think was intended)

Not certain about って, but everything else seems right on. Nice job Mattan. :D

今朝、四時間ぐらいに雨が降りました。ダメですよ～寒くて悲しいってかんじがあるから、嫌いです。春が大好きです！今週末の後、春になります。凄いね

けさ、よじかんぐらいにあめがふりました。ダメですよ。あめはさむくて、かなしいってかんじんがあるから、きらいです。はるがだいすきです！こんしゅうまつのあと、はるになります！！！すごいね！！！

kesa = this morning
yojikan instead of yonjikan
samukute, kanasii tte kanji
- samukute, kanasii - te form when using more than one adjective.
- tte - is being used to mean "in reference to"
- kanji - feel(ing)
- I'm not 100% on this :3
aru = have
kara = because/since/so

konshuumatsu = this weekend
ato = after
haru ni narimasu = it will become Spring.

I'm don't get what you meant by "hare," did you mean "haru" (spring). If so, that's how I wrote the above.

When you are writing about personal stuff in blogs or diary or whatever, its unnatural to write in polite/formal prose; unless you have a direct audience you are writing to. I would have written it different, but I didn't know if you wanted to still keep the polite speech...
