Central New Mexico Weather: 8/28/18

Yesterday was sunny, warm and still.  It clouded up a bit in the afternoon (more so than I had imagined), but it did not rain.  The evening was clear and pleasant.

This morning has been warm and still, with some high cirrus clouds over the eastern skies, and clear skies to the west.

The NWS in Albuquerque, NM, forecasts (for Rio Rancho, NM) a sunny day, with a high temperature near 90 F.  Winds will be from the west at 5-10 mph.  Tonight will be mostly clear, and a low temperature of 60 F.  Winds will be from the west at 5-10 mph, becoming northeast after midnight.

The NWS in Albuquerque, NM, forecasts (for Socorro, NM) a sunny day, with a high temperature near 93 F. The winds will be from the north at 5-10 mph.  Tonight will be mostly clear, with a low temperature of 62 F.  The winds will be from the north at 5-10 mph, becoming west by midnight.

The NWS in Albuquerque, NM, forecasts (for Magdalena, NM) a sunny day, with a high temperature of 84 F.  The winds will be from the northwest at 5-10 mph.  This evening will be mostly clear, with a low temperature of 56 F.  The winds will be from the west at 5-10 mph.

The visible satellite imagery shows a thin, high blanket of clouds over much of the state this morning.

The 12Z upper air sounding from Albuquerque shows that the atmosphere has dried out significantly, as compared to last week. There was 0.49 inches of precipitable water present in the column.  There was no Convective Available Potential Energy (CAPE) and no Convective Inhibition (CINH).  The Lifted Condensation Level (LCL) was 1780 m.  There was a small thermal inversion near the surface, and the 0-3 km average lapse rate was 6.0 C/km.

The hodograph shows that there was 18 kts low-level shear (due mostly to directional changes) and 38 kts deep-layer shear (due mostly to speed changes).

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

The surface pressure chart shows no strong pressure systems or gradients over the state this morning.  The RAP shows that thermal low pressure is expected to develop over the eastern half of the state within the next six hours.  No strong pressure gradients are expected with this thermal low.

The NAM 250 mb chart shows zonal to southwesterly flow over New Mexico today.  There will be a weak jetstreak over the northern third of the state.

The NAM 850mb chart shows some Cold Air Advection (CAA) moving in to the northeastern corner of the state over night.  It is a weak backdoor cold front that will be ejected east with diurnal heating tomorrow.

The HRRR simulated reflectivity shows precipitation is unlikely.  This image has been excluded from today’s post.

The HRRR predicts that the high temperatures for the Rio Grande River Valley will peak around 22 Z, reaching into the upper-80’s F.

The HRRR shows that the Albuquerque Metro area will remain dry today, with dewpoints only reaching into the mid 30’s.  Notice the sharp dryline in the northeastern corner of the state- this helps mark our back door cold front (which is colinear with this sharp dryline).

The HRRR shows no strong wind gusts today.  This image has been excluded from today’s post.

The HRRR shows that cloud cover will be light today.  This image has been excluded from today’s post.

Today will be warm, sunny, and dry.  I am a little done with the humid weather anyhow.

Thank you for reading my post.
