New Mexico Weather: 10/10/17

Yesterday was mostly sunny, windy, and becoming cooler.

This morning has been sunny, cold and still.

National Weather Service (NWS) in Albuquerque forecasts (for Socorro) a sunny day, with a high temperature of 68 F.  The winds will be from the north at 5 mph, becoming southeast in the afternoon.  This evening will be mostly clear, with a low temperature of 43 F. Winds will be south at 5 mph.

The NWS in Albuquerque forecasts (for Magdalena) a sunny day, with a high temperature of 64 F. The winds will be from the east at 5-10 mph, becoming southeast in the afternoon. This evening will be clear, with a low temperature of 38 F. Winds will be from the southeast at 5-10 mph, becoming southwest after midnight.

The NWS in Albuquerque forecasts (for Rio Rancho) a sunny day, with a high temperature of 64 F.  The winds will be from the east at 5 mph, becoming south in the afternoon.  This evening will be clear, with a low temperature of 40 F. Winds will be calm, becoming northeast at 5 mph after midnight.

The NWS has issued a Freeze Warning and for much of the state through the morning hours.  Temperatures are expected to drop to freezing or near-freezing levels, even as far south as the Albuquerque Metro area.  There are several Hard Freeze Warnings for the higher elevations as well.  The Watches and Warnings graphic is shown below:

The visible satellite imagery shows no clouds over the state so far this morning.  This image has been excluded from today’s post.

The infrared satellite imagery shows no thick clouds over the state this morning.  This image has been excluded from today’s post.

The water vapor imagery shows that some moisture has returned aloft.

The 12Z sounding from Albuquerque shows very dry air above 800 mb.   There was 0.21 inches of precipitable water present in the column this morning.  There was no Convective Available Potential Energy (CAPE) and no of Convective Inhibition (CINH) present.  There was a small thermal inversion near the surface, and the 0-3 km average lapse rate was 3.2 C/km.

The hodograph shows that there was 7 kt of low-level shear (mostly due to directional changes) and 29 kts of deep-layer shear (mostly due to speed changes).

The surface observations (from the SPC Mesoscale Analysis Map) show cold temperatures and moderate humidity, (based on the surface dewpoint depressions).  The winds are light, and the skies are clear over most of the state.  Clearly, the cold front has passed through the state.

The surface pressure chart shows that high pressure dominates the state, with a high pressure center of 1032 mb.  There is a slight pressure gradient on the edges of the high pressure system, but the winds are not strong at this time.  The RAP shows that the pressure will drop with diurnal heating over the next six hours, though high pressure will still rule the state today.

Synoptically speaking, the 300 mb NAM chart (from Unisys) shows moderate zonal flow over the state, particularly over the northern part of the state today.  The southern part of the state will have light zonal flow as the trough moves northeast and attenuates.

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

The 700 mb NAM chart is unavailable at this time.

The 850 mb NAM chart shows no strong thermal advection over the state today.  This chart has been excluded from today’s post.

The Precipitation chart shows very little chance of precipitation over the state today.  This chart has been excluded from today’s post.

High pressure and dry air will be the dominant forces today.  The air is very cold, but it will warm up with diurnal heating today, and there is no more cold air advecting into the area today.  It should turn out to be a cool, but pleasant day.
