Possible Tornado NW Of Clovis Yesterday Evening - Heavy Snows For The Sac's Today Into Tonight.


Possible Tornado Northwest Of Clovis Yesterday Evening.






What appears on these radar screenshots to be a low topped supercell thunderstorm produced a possible tornado about 13 miles northwest of Clovis, New Mexico at 4:52 PM MST Friday, December 27, 2019. A tornado vortex signature was noted on the radar with a base at around 800' extending up through nearly 5,000' Gate to gate wind shear at this time was 43 knots/ inbound and 72 knots outbound at 800' above the ground (the lowest tilt on the radar). 

The parent thunderstorm was moving to the northeast at 30 mph. It was a quick spin up and the rotation that promoted the Tornado Warning for East-Central Curry County quickly fell apart. Pea size hail was reported in Portales and near Clovis, while penny size hail was reported 4 miles north of Newkirk, southwest of Tucumcari.

Looking at the Cross-Sectional view (second screenshot from the bottom) and the Volumetric view (bottom screenshot) distinctively depicts a very slanted updraft into the thunderstorm. Note too that it only managed to top out at about 30,000'.

Colder Sunday Into Tuesday.
As the Winter Storm to our west works its way eastward into the area today into Sunday morning scattered rain showers and mountain snows are forecast to be on the increase over the area. Snow should start around noontime in the Sacramento mountains with lowering snow levels this afternoon into tonight.

Light rain showers tonight may change over to light snow showers across parts of the Southeastern Plains. Current thinking is that the best chances for snow locally will occur from about Roswell northward. With the heavier snowfall confined to the Sacramento mountains. Cloudcroft stands to get 5" to 8" from this storm with greater totals above 9,000'. The Ruidoso area should see 1" to 3" with 4" to 8" above 7,500'. Ski Apache may end up with a foot of new snow or more.

West winds gusting to around 40 mph today into tonight across the Sacramento mountains will cause some blowing and drifting of the snow...especially at the higher elevations. Wind chill values will range from around 10º at the lower mountain locations today, to near -10º at the higher elevations tonight, and -2º at the lower elevations tonight.
