Yesterday was cool, still and mostly sunny. Last night was cool, still and clear.
This morning in Rio Rancho, the weather has been cool, still and mostly sunny, with a few high cirrus clouds. The backyard weather station says the temperature is 45.3 F, with a relative humidity of 55%, relative pressure of 30.30 in Hg and steady, and 3.5 mph west but variable winds.
The National Weather Service (NWS) in Albuquerque forecasts a sunny day today, with a high temperature of 56 F. The winds will be from the south at 5 mph. This evening will be clear, with a low temperature of 36 F. Winds will be from the southwest at 5 mph. The NWS has issued a Hazardous Weather Outlook concerning a back door cold front that will bring cooler temperatures and gusty winds through to the central mountain chain late this evening and early tomorrow morning.
The visible satellite imagery shows some light, high clouds over much of the state. Even on this image, you can see that they are very thin.
The enhanced infrared satellite imagery shows that the few clouds that exist are not very thick.
The water vapor satellite imagery shows some moisture collected at the thicker clouds.
Soundings are not available at this time, nationwide. I’m not sure why.
The surface observations (from the SPC Mesoscale Analysis Map) show cold temperatures, clear skies, low dew points and light, variable winds. There may be a weak dryline through the eastern third of the state, as told by the dewpoint step.
The surface pressure chart shows high pressure over the state today, but low pressure over the northeastern corner. There is a moderate pressure gradient in the northeast because of this low. The RAP shows that the low will expand and intensify, but the gradient will actually weaken, as the high pressure over the southwest will weaken as well.
Synoptically speaking, the 300 mb NAM chart (from Unisys) shows weak northwesterly to zonal flow over the state today.
The 500 mb NAM chart shows no major vorticity advection over the state today. This chart has been excluded from today’s post.
The 700 mb NAM chart shows no rapidly-rising air over the state today. This chart has been excluded from today’s post.
The 850 mb NAM chart shows that the back door cold front has not yet reached our borders by 0Z. This chart has been excluded from today’s post.
The Precipitation chart shows no precipitation over the state today. This chart has been excluded from today’s post.
Today will be sunny, cool and clear for most of the state. The temperatures will begin to rise slightly. We are headed into a flat pattern with nearly-zonal flow for a few days.
