In Rio Rancho this morning, the weather is cool, clear and still. There are no clouds in the sky. The backyard weather station says that the temperature is 64.2 F, the relative humidity is 72%, and the relative pressure is 30.18 in Hg.
The National Weather Service (NWS) in Albuquerque forecasts
a clear and sunny day today in the Metro area.
The visible satellite imagery shows a few clouds in the southern part of the state, as well as an interesting feature north of Tucumcari and crossing into Texas. There is some sort of little tube-shaped cloud running west-southwest to east-northeast.
The enhanced infrared satellite imagery shows that the clouds in the south are not very thick.
The water vapor satellite imagery shows that there is dry air in the middle of a large trough that starts in Wyoming and dips south through Texas. Behind it, there is some moisture return into New Mexico, and we can see that the trailing edge of the trough is not nearly as defined as the leading edge.
There are no soundings available yet this morning, nationwide. There wasn’t even a 0Z sounding last night, so I think there may be a problem with the soundings server.
The surface observations (from the SPC Mesoscale Analysis Map) show the cooler surface temperatures, still winds, and dewpoints in the 50’s for most of the state. There are no major frontal boundaries present in this chart.
The surface pressure map shows that most of New Mexico is under high pressure, from 1020 mb to 1024 mb. To the west, there is a strong pressure gradient across western Arizona, but no strong pressure gradients in New Mexico.
Synoptically speaking, the 300 mb NAM chart (from Unisys) shows a 90 degree turn of the jetstream over Wyoming. It traces south along I-25 and then veers east over Mexico. This branch of the jetstream has left a mass of dry, continental air over the Great Plains, though as mentioned earlier, there is some moisture return behind it.
The 500 mb, 700 mb, and 850 mb charts show no significant vorticity advections, rising air, or thermal advections over the state.
Overall, I expect today to be a boring day, weather-wise, over the state. Clear, sunny, skies, with temperatures a little cooler than last week. Perhaps fall is almost here.
Thank you for reading my forecast.
