New Mexico Weather: 12/7/17

Yesterday was mostly sunny, still and cold.

This morning has been cold, partly cloudy and still.  There were clouds at sunrise, and I have heard reports that there was snow falling one train station north of where I boarded.

National Weather Service (NWS) in Albuquerque forecasts (for Socorro) a mostly sunny day, with a high temperature of 40 F. The winds will be from the north at 10-15 mph.  This evening will be mostly clear, with a  low temperature of 18 F. Winds will be from the northwest at 10 mph.

The NWS in Albuquerque forecasts (for Magdalena) a partly sunny day, with 20% chance of snow, and a high temperature of 33 F. The winds will be from the north at 10-15 mph. This evening will be partly cloudy, with a low temperature of 15 F.  Winds will be from the northwest at 10 mph.

The NWS in Albuquerque forecasts (for Rio Rancho) a mostly sunny day, with a  high temperature of 38 F.  The winds will be from the east at 10 mph, becoming northwest in the afternoon.   This evening will be partly cloudy, with a low temperature of 21 F. Winds will be from the northwest at 10 mph.

The NWS in Albuquerque has issued a Hazardous Weather Outlook concerning an upper-level disturbance that will bring a few inches of snow to the mountains in the northern part of the state.

The visible satellite imagery is unavailable at this time.

The infrared satellite imagery shows that the clouds are relatively thin, as compared to yesterday.  Winter precipitation does not require thick convective clouds.

The water vapor imagery shows nearly uniform moisture over the state this morning.

The 12Z sounding from Albuquerque shows a dry, cold atmosphere, with a nearly-saturated layer from 650 mb to 550 mb.  There was 0.18 inches of precipitable water present in the column this morning.  There was no Convective Available Potential Energy (CAPE) and no Convective Inhibition (CINH) present.  There was no thermal inversion near the surface, and the 0-3 km average lapse rate was 7.5 C/km.

The hodograph shows that there was 17 kt of low-level shear (due mostly to directional changes) and 61 kts of deep-layer shear (due mostly to speed changes).

The surface observations (from the SPC Mesoscale Analysis Map) show cold temperatures and low humidity, (based on the surface dewpoint depressions). The skies were cloudy over most of the state, and the winds light.

The surface pressure chart shows that high pressure and a moderate pressure gradient dominate today’s weather.  The RAP shows that high pressure will linger for at least the next six hours.

Synoptically speaking, the 300 mb NAM chart (from Unisys) shows strong northeasterly flow as the deforms southwest into New Mexico.

The 500 mb NAM chart shows that there will be some Negative Vorticity Advection (NVA) associated with the trough’s movement this evening.

The 700 mb NAM chart shows no pockets of rapidly-rising air over the state today.  This chart has been excluded from today’s post.

The 850 mb NAM chart shows no strong movement of the cold front.  This chart has been excluded from today’s post.

The Precipitation chart shows that measurable precipitation is possible in the very southern part of the state by 00Z.

It’s another cold day in New Mexico.  I actually brought my gloves today, as I expected the steering wheel and shift knob to be quite cold this morning.  High pressure will rule the day, though a moderate pressure gradient may create slightly breezier conditions today, as compared to yesterday.
