In Rio Rancho this morning, the weather is bitter cold. My backyard weather station says the temperature is 19.4 F, the relative humidity is 71%, the relative pressure is 30.21 in Hg and steady, and the winds are still.
The National Weather Service (NWS) in Albuquerque forecasts a cold day today, mostly sunny, with a high of 36 F. This evening, expect mostly clear skies, and a low temperature of 13 F. The NWS has issued a Hazardous Weather Outlook concerning the extreme cold, as temperatures in the northern part of the state and at higher elevations may reach -20 F.
The visible satellite imagery is not available at this time.
The enhanced infrared satellite imagery shows no thick clouds, and has been excluded from this post.
The water vapor satellite imagery shows that there is uniform moisture over New Mexico, except for a strange stripe that extends through the southern half of the country.
The 12Z upper air sounding from Albuquerque is not available at this time.
The surface observations (from the SPC Mesoscale Analysis Map) show the light winds, clear skies and extremely cold temperatures. Note the -27 F in the northern mountains!
The surface pressure map shows high pressure over much of the state this morning. There is strong high pressure over northern Colorado, and while it doesn’t drift into New Mexico, we are under its influence. The RAP shows that we will be under higher pressure for the next six hours, at least.
Synoptically speaking, the 300 mb NAM chart (from Unisys) shows a split flow pattern. The northern branch dips down through the Great Plains and spreads out into New Mexico.
The 500 mb NAM chart shows no strong vorticity advection across the state today. It has been excluded from today’s post.
The 700 mb NAM chart shows no strong rising air across the state today. It has been excluded from today’s post.
The 850 mb NAM chart shows no strong thermal advection across the state today. It has been excluded from today’s post. The temperature drop this evening has more to do with clear skies than synoptic cooling.
Overall, I expect a bitter cold day. I am not looking forward to this cold, as I did not move to New Mexico to bundle up! Otherwise, the skies will be clearing and little to no precipitation is expected in the Rio Grande River Valley.
Thank you for reading my forecast.
