As the front continues to push south and west, windy conditions are possible this morning.

The 12Z upper air sounding from Albuquerque, NM, shows a dry atmosphere.  There was 0.26 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 2421 m. There was a moderate thermal inversion near the surface and the 0-3 km lapse rate was 3.2 C/km. The hodograph shows that the low-level shear was 18 kts (due mostly to directional changes) and the deep-layer shear was 29 kts (due to mostly to speed changes).

The surface observations chart (from the SPC Mesoscale Analysis Map) shows cool temperatures and very low humidity.  The skies are sunny (according to the sensors) and winds are still.

The surface pressure chart (from the SPC Mesoscale Analysis Map) shows we are under high pressure, with a moderate pressure gradients radiating from the northeastern corner of the state.  The RAP shows that pressure will drop with diurnal heating, and the pressure gradient is expected to shift and tighten over the northern part of the state.

The NAM 250 mb chart shows light, northwesterly flow aloft.

The NAM 700 mb and 850 mb charts show Cold Air Advection (CAA) will continue today and tonight, as a trough lingers over the Great Plains.

The Nested NAM predicts that the high temperatures for the middle Rio Grande River Valley will peak in the mid 70s F.

The low temperatures are expected to drop into the mid 40s F right around sunrise tomorrow morning.

The Nested NAM shows that the dewpoints will peak in the mid 20s F.

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

The Nested NAM simulated infrared chart shows very few clouds over the state today. This image has been excluded from today’s post.

Today will be pleasant, and I’ll end up inside almost the entire day.
