Made some adjustments to the wind advisory as KSRR was nearly hitting
high wind in the last hour. Also added Union and Harding county to
the wind advisory for later this afternoon and evening with the H7
temperatures diving and hefty pressure rises forecast in that area. 
Did not add thunder to the wx grids although we know it is around the
ABQ and SAF metros at this time as it looks to be somewhat random 
although it does appear to be in vicinity of the frontal boundary. 
Updated ZFP just transmitted.

A cold front will blast through New Mexico today and allow rain to 
change to snow in the higher terrain. A few inches are likely over 
the northern mountains and across the far northeast plains. Strong 
northwest winds will develop over the state today with widespread 
wind gusts of 40 to 50 mph, especially over the eastern plains. A 
brief break is expected on Monday with warmer temperatures, however 
windy conditions will persist over the region. A strong cold front 
will surge through the state Tuesday with more strong winds and a 
slight chance for light snow across northeast New Mexico. Tuesday 
night will be the coldest night in the past couple weeks with single
digits across the northern mountains and teens and 20s elsewhere. A 
slow warming trend will begin Thursday with lots of 50s and 60s by 
the weekend.


Closed upper-level low is forecast to slide eastward along the NM-CO 
border today. Precipitation will favor the northern and western 
mountains today, mainly in the form of snow as temperatures drop 
behind the associated cold front. Added the Johnson and Bartlett 
Mesas including Raton Pass zone to the winter weather advisory with 
several inches of accumulation a good bet above 7000 feet likely 
impacting travel at/near pass level.

As surface low pressure deepens across northeast NM this afternoon, 
wind will be the main weather impact for many locations but 
especially for areas east of the central mountain chain and near and 
south of Interstate 40. Issued a wind advisory as a result with 
sustained west winds in the 30 to 40 mph with gusts to 50 mph 
likely by afternoon. 

Upper low shifts east of the state on Monday with dry northwest flow 
aloft moving in. Meanwhile, a bitterly cold upper-level trough 
sliding southeastward through WY and northeast CO is forecast to 
send a backdoor cold front into northeast NM late Monday afternoon. 
Very cold air will start to push into Union and far eastern Colfax 
counties toward sunset Monday.

A much colder airmass will surge south through the rest of eastern 
NM Monday night as a 120 kt polar jet shifts through the central 
Rockies. Strong cold air advection plummets 700mb temps to near -12C 
behind the front with widespread windy conditions once again for the 
region Tuesday afternoon. The wind will make it feel more like mid 
winter. Model guidance trended lighter with snowfall across northeast
NM Monday night and Tuesday despite a moist, mid level baroclinic 
zone over the area in the wake of the departing upper level trough. 
The low level airmass is just way too dry and surface convergence is 
weak so PoPs were lowered to only slight chance. The very dry airmass
building into the area with strong surface high pressure will lead 
to the coldest morning in a couple weeks on Wednesday morning. Single
digits will be common over the northern mountains with teens and 20s

Northwest flow aloft will continue Wednesday and Thursday with a 
couple weak back door fronts expected over northeast NM. The overall 
pattern will be more tranquil with slowly warming temps and sunny 
skies. A weak upper level ridge is projected Friday with even warmer 
temps, light winds, and more sunny skies. This ridge will break down
over the weekend with increasing high clouds and near normal temps.



While rain and snow showers continue in western and northern 
portions of the state today, strong west winds will develop mainly 
east of the central mountain chain and along and south of Interstate 
40. Strong winds are forecast to combine with a dry airmass to 
produce an hour or two of marginal critical conditions for the east-
central and southeast plains Monday afternoon. A strong but dry cold 
front is forecast to bring bitter cold temperatures to the northeast 
half or so of the state Monday night and Tuesday. The cold condtions 
continue into Wednesday before temperatures rebound to near seasonal 
averages for late February on Thursday and Friday.
