Christmas Road Trip 2017: Day 18

Today is the eighteenth day of our annual Christmas Road Trip.  Yesterday, we drove in the bitter cold from Effingham, IL, to Tulsa, OK.  As we went south, the temperature increased, even into the night.  When we arrived here at 1:00 am, the temperature was a comparatively tropical 16 F.

Today will theoretically be our last day of traveling.  We will drive back to Rio Rancho and arrive there late tonight or early tomorrow morning.

The NWS in Tulsa, OK, forecasts (for Tulsa, OK) a mostly cloudy day, with slight chance of flurries, and a high temperature of 24 F.  Winds will be calm and variable, producing wind chill values from 9 F to 19 F.

The NWS in Albuquerque, NM, forecasts (for Rio Rancho, NM) a partly cloudy night, with a low temperature of 24 F.  Winds will be from the northeast at 5 mph.

The surface observations (from the SPC Mesoscale Analysis Map) show cold temperatures and low humidity (based on the surface dewpoint depressions). The skies are cloudy across much of our travel route, becoming clear after Amarillo.  The winds are light and from the northeast.

Today, we will begin to leave the high pressure that has been associated with this cold weather.  As we travel west, the pressure will drop to 1020 mb- still higher than average atmospheric pressure, but lower than we have seen for the past few days on this road trip.

The HRRR simulated reflectivity shows no precipitation today.  I didn’t include this image.

The HRRR has the high temperatures somewhere around 23 Z, as we drive west.

However, in spite of my hopes, the temperatures drop drastically, even into New Mexico, later in the evening.

Today will be cold, but not as cold as it was yesterday.  Already, we are 20 F warmer than yesterday, and the winds are lighter.  However, it is still quite cold, and all of my dreams of returning to sunny, warm, New Mexico may remain just that- dreams.

Thank you for reading my post.
