Hey, all...

I was on the NOAA's website and ran across this map... but I can't find a legend for it anywhere. saywhat

I know what the blue lines with the triangles mean, I know what the red lines with the half circles mean, plus those two alternating, the yellow lines, and the 'H's and 'L's, obviously....

But I can't for the life of me figure out what the things in lime green or cyan or the dotted rosy orange lines are... There's also, in the upper left, a blue, triangle line that merges into a violet line. I can't figure that one out either. confused

Help? saywhat

The yellow lines are the Isobars, I think the areas with a green line
around them mean that there is a chance of rain there? the red line
over the plains is a warm front. The blue and red line over the pacific
northwest is a stationary front. the Ls are Low pressure areas, The Hs
are High pressurer areas.

He's correct... the green circle's are the chances for precip (NOT rain), and the symbol inside the box represents the type of precip... rain, snow, etc.

EDIT: Here's the exact key:

Welcome to the world of synoptic meteorology... these may be of use to you in reading the maps and others like it.
