[FRIAM] The Dry Line

[Nicholas Thompson]

Nice dryline hanging out over the central mountain chain.  Pay attention to
the parallel ranks dashed lines running north and south. If you drive to
Las Vegas NM this morning you would really notice the difference.

Note low pressure to the west of us.  the map below shows a surge of moist
air nw-ward from the rio grande valley into SE NM.

As this system drags eastward you would think east tx would be in for
severe weather.  Lets look at tomorrow s forecastand  and see.  .

Just rain, I guess.  Note the dry line hanging back in NM as the low center
moves into CO and a thin wedge of warm moist air works its way up the
Sangrees.  Not sure why this isnt a tornado lovers paradise, but Ihaven't
looked at the upper air maps.  Open half circles represent the dry line;
closed red half circles the warm front.  triangular blue, cold front.
