Central New Mexico Weather: 11/21/20


Yesterday was warm and sunny.

This morning, Rio Rancho has been cool, partly sunny and still.

From the NWS in Albuquerque, NM:  An upper-level speed max has created a few showers and thunderstorms in the northern part of the state, but showers are unlikely to spread much farther south. Yesterday’s cold front is washing out, and temperatures will remain a few degrees above average. Partly to mostly cloudy skies are expected

The NWS in Albuquerque, NM, forecasts (for Rio Rancho, NM) a partly sunny day, with a high temperature of 65 F. The winds will be from the northeast at 5 mph, becoming southerly in the afternoon. This evening will have increasing clouds, with a low temperature of 40 F. The winds will be from the north at 5 mph.

The NWS in Albuquerque, NM, forecasts (for Socorro, NM) a partly sunny day, with a high temperature of 69 F. The winds will be from the north at 5 mph, becoming southerly in the afternoon. This evening will be partly cloudy, with a low temperature of 44 F. The winds will be from the south at 5 mph, becoming northerly by midnight.

The NWS in Albuquerque, NM, forecasts (for Magdalena, NM) a partly sunny day, with a high temperature of 66 F. The winds will be from the northwest at 5 mph, becoming southeasterly in the afternoon. This evening will be partly cloudy, with a low temperature of 37 F. The winds will be from the southwest at 5 mph, becoming westerly after midnight.

The NWS in Albuquerque, NM, forecasts (for Mountainair, NM) a partly sunny day, with a high temperature of 63 F. The winds will be light and variable, becoming southwesterly at 5-10 mph this afternoon. This evening will be mostly cloudy, with a low temperature of 35 F. The winds will be from the southwest at 5 mph, becoming northeasterly after midnight.

The visible satellite imagery shows light cloud cover over most of the state, with thicker clouds over the northeastern corner.

The 12Z upper air sounding from Albuquerque, NM, shows a humid atmosphere this morning. There was 0.52 inches of precipitable water present in the column this morning. There was no Convective Available Potential Energy (CAPE), no Convective Inhibition (CIN), and the Lifted Condensation Level (LCL) was 1771 m. There was a small thermal inversion near the surface and the 0-3 km lapse rate was 5.0 C/km. The hodograph shows that the low-level shear was 16 kts (due mostly to directional changes) and the deep-layer shear was 58 kts (due mostly to speed changes).

The surface observations chart (from the SPC Mesoscale Analysis Map) shows cool temperatures and moderate relative humidity.  The skies are sunny, (according to the sensors) and winds are light and variable.

The surface pressure chart (from the SPC Mesoscale Analysis Map) shows that we are under slightly higher pressure with no strong pressure gradients at this time. The RAP shows the pressure will remain high for at least the next six hours.

The NAM 250 mb chart shows strong zonal flow aloft.

The NAM 850 mb chart shows a Cold Air Advection (CAA) approaching from the northeast. One round passed through last night, and we can expect another one tomorrow.

The Nested NAM simulated reflectivity chart shows some very light precipitation is possible across the northern half of the state today.

The Nested NAM simulated precipitation chart shows rain is possible along the very northern edge of the state. This chart shows rain through 12 Z tomorrow morning.

The Nested NAM predicts that the high temperatures for the middle Rio Grande River Valley will reach the mid 60s F.

The Nested NAM shows the low temperatures are expected to drop into the mid 40s F by tomorrow morning.

The Nested NAM shows that the dewpoints will slowly rise from the upper 20s F into the mid 30s F overnight.

The Nested NAM shows strong winds are unlikely. This chart has been excluded from today’s post.

The Nested NAM simulated infrared chart shows light cloud cover off and on all day and night.

Today should be partly to mostly cloudy, with pleasant temperatures and only very light winds. I will probably go for a run in a few minutes, due to the pleasant conditions.
