Cooler than expected today, severe weather for the south, some comments, and the LI forecast:

- The warm front is not going to make it to Long Island today, so instead of highs in the low to mid 70's, we will be stuck mostly in the low 60's (see 1st image).

- In the 3rd image you can see the severe weather potential for today.

- Thursday is still the best day of the week for Long Island. The best chance of showers on Friday is probably after 7 PM, although there is still a chance of a shower before then, especially in western Long Island.

- Some showers likely return in the afternoon on Mother's Day.
