Weather Map

[asterroc]

Anyone *cough*meredithanne42*cough* know what the yellow line with half-circles over west Texas means? I've never seen it before.



ETA: And while I'm at it, why does it make a difference if a cold front moves under warm air, or a warm front moves over cold air? They're the same except for the stationary ground under them, why does that affect them?

A more educated guess:

from looking at the other maps, absolutely nothing interesting is happening in that same area. Perhaps it's a high pressure system.

Nope, high pressure systems are marked with an H, lows with an L, and various other things with other symbols. I could probably dig it up more deeply elsewhere, but I'm lazy. :-P
