.PREV DISCUSSION... /ISSUED 0140 AM CDT Tue Mar 20 2018/

A shortwave trough will move eastward across the Southeast today,
while an upper ridge persists over the western CONUS. At the
surface, high pressure will be in place over much of the Plains in
the wake of a cold front passage. Modest lee cyclogenesis will occur
across the southern High Plains as a low-amplitude shortwave trough
moves through the upper ridge, and a lee surface trough will extend
southward from the low across the southern High Plains.

...Portions of the Southern High Plains...
Confidence has increased that elevated conditions will occur this
afternoon across part of east-central NM as modestly enhanced
mid-level winds become diurnally mixed the surface and the pressure
gradient strengthens slightly with the development of the lee
trough. Given an antecedent dry airmass, RH values will fall into
the 10-15% range by peak afternoon heating. Sustained westerly winds
of 15-20 mph should also develop. Have therefore introduced a small
elevated area across portions of east-central NM.
