DISCUSSION...
Shortwave ridging aloft this afternoon with west to southwest
surface winds has lifted temperatures into the low 70s across
the region. A Pacific low currently moving onshore is producing
significant cloud cover across the Pacific Northwest. High clouds
from that system can be seen getting picked up by northwest flow
aloft from the large ridge of high pressure over the Southwest,
providing a thin veil of cirrus across West Texas. High
temperatures have been left unaffected due to enough filtered
sunshine and dry airmass at the surface with dewpoints on the
single digits and teens on the Caprock, into the low 20s just to
the east off the Caprock.

Short wave trough later tonight will help reinforce a surface
cold front expected to move south out of the Texas Panhandle
early Tuesday morning and through the South Plains by early
afternoon. Temps will cool off marginally for Tuesday back down
into the mid-upper 60s. Though relatively light, the surface
winds will maintain northerly component through the day and
weaken further allowing for radiational cooling to drop lows
on Wednesday morning near the freezing mark and highs on Wednesday
will be more seasonable right around 60 for most spots.

Once the cold front is through our area tomorrow, the upper level
ridge to our west amplifies significantly through midweek and into
the weekend keeping temps above normal through the forecast period
despite yet another dry cold front that will push through late
Friday into early Saturday. The current pattern does not bode well
for precipitation chances over the next week at least.
