New Mexico Weather: 11/18/17

Yesterday was sunny, warm and clear in Albuquerque.  However, by the afternoon, conditions became quite windy, and the overnight temperature dropped much cooler.

This morning has been sunny, cool and breezy.

National Weather Service (NWS) in Albuquerque forecasts (for Socorro) a sunny day, with a high temperature of 59 F.  The winds will be from the north at 5-15 mph.  This evening will be clear, with a low temperature of 26 F. Winds will be from the northwest at 5 mph.

The NWS in Albuquerque forecasts (for Magdalena) a sunny day, with a high temperature of 54 F. The winds will be from the north at 5-10 mph.  This evening will be clear, with a low temperature of 20 F. Winds will be from the north at 5 mph, becoming west after midnight.

The NWS in Albuquerque forecasts (for Rio Rancho) a sunny day, with a high temperature of 55 F.  The winds will be from the northwest at 5 mph.   This evening will be clear, with a low temperature of 24 F. Winds will be from the northwest at 5 mph, becoming calm after midnight.

The NWS has issued a Hazardous Weather Outlook concerning the hard freeze likely tonight over much of the state.  The combination of a Pacific cold front and a backdoor cold front will bring temperature much lower to more seasonal levels.

The visible satellite imagery shows few clouds over the state today.  This image has been excluded from today’s post.

The infrared satellite imagery shows few clouds over the state today.  This image has been excluded from today’s post.

The water vapor imagery shows that last week’s moisture has moved east, and a cool, dry airmass is moving into the state from the west.

The 12Z sounding from Albuquerque shows an extremely dry atmosphere.  There was 0.09 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 a moderate thermal inversion above the surface, and the 0-3 km average lapse rate was 4.2 C/km.

The hodograph shows that there was 37 kt of low-level shear (due mostly to directional changes) and 100 kts of deep-layer shear (due mostly to speed changes).

The surface observations (from the SPC Mesoscale Analysis Map) show cool temperatures and low humidity, (based on the surface dewpoint depressions).  The winds are light, and the skies are clear.

The surface pressure chart shows that higher pressure dominates the state this morning.  The RAP shows that high pressure will continue to dominate over the next six hours.

Synoptically speaking, the 300 mb NAM chart (from Unisys) shows light zonal flow over the state today.

The 500 mb NAM chart shows no strong vorticity advection over the state today.  This chart has been excluded from today’s post.

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 some Cold Air Advection (CAA) just creeping into the northeastern corner of the state by 00Z.  The CAA gets stronger through the night.

The Precipitation chart shows that precipitation is unlikely today.  This chart has been excluded from today’s post.

I had debated camping out this weekend in my car to play in a radio contest.  However, given the low temperatures and my recovering from a cold, I don’t think I will.  It’s going to be a cold morning tomorrow.
