PREV DISCUSSION... /issued 223 PM CST Sat Feb 20 2021/
DISCUSSION...
There is mostly westerly flow aloft over West Texas and Southeast
New Mexico. An upper trough is beginning to dig southeastward across
the western part of the country. Southerly winds are expected across
the area today with highs mostly in the 60s and 70s. Areas that have
received the most snow in the past few days will be colder. Patchy
fog is possible tonight and early Sunday morning across portions of
Terrell and Reagan Counties where the NAM12 shows very low dewpoint
depressions for tomorrow morning. The upper trough to the west will
move over the central part of the country on Sunday with the base of
the upper trough moving over West Texas and Southeast New Mexico.
High winds from the base of the trough are expected to impact the
Guadalupe Mountains so a High Wind Warning is in effect there
beginning tonight and continuing into the early morning hours on
Sunday. The upper trough will result in a cold front moving into the
area during the day on Sunday. This front will not have a big impact
on temperatures with highs across most of the area expected to be in
the 50s and 60s.
The previously mentioned upper trough moves eastward on Monday.
Southwesterly surface winds are expected on Monday as a surface
trough develops across the higher terrain. High temperatures are
again expected to mostly be in the 50s and 60s. Temperatures are
expected to warm up into the 70s across most of the area on Tuesday
with southwest winds. On Wednesday, an upper trough will extend from
over the Midwest southwestward to over Utah and Colorado. A cold
front will begin pushing into the area on Wednesday. This colder air
will continue to come into the area on Thursday with high
temperatures in the 40s expected across most of the Permian Basin.
There is a possibility of precipitation with this system but
confidence is very low so will keep the forecast dry for now.
Another upper trough will move over the central part of the country
Friday into next Saturday. Another cold front may move into the
area, but temperatures will likely range from the 50s to the 70s.
