Christmas Road Trip 2017: Day 17

Today is the seventeenth day of our annual Christmas Road Trip.  Yesterday, we spent the evening driving across the frigid Midwest, crossing rural Ohio, Indiana and Illinois, stopping for the night in Effingham, IL.

Today, we will continue southwest, driving from Effingham, IL, to somewhere between Joplin, MO, and Oklahoma City, OK, depending on how tired and how late we drive.

The NWS in Lincoln, IL, forecasts (for Effingham, IL) a mostly sunny day, with a high temperature of 7 F.  Winds will be 6-10 mph from the northwest, and will produce wind chill values of -13 to -23 F.

The NWS in Norman, OK, forecasts (for Oklahoma City, OK) a mostly cloudy night, with a low temperature of 10 F.  Winds will be from the east-northeast at 5-9 mph, becoming east at 5 mph, producing a wind chill value of -1 F.

The surface observations (from the SPC Mesoscale Analysis Map) show extremely cold temperatures and low humidity (based on the surface dewpoint depressions). The skies are clear and the winds are light and from the northwest.

I don’t know how else to express the strength of this high pressure system.  Check it out, 1050 mb, or 31.00 in Hg.  It’s about as strong as I’ve ever seen before.  This high pressure is similar to that experienced during the “Siberian Highs” of the winter in Russia.

The temperature is cold enough that the IR satellites are getting fooled.  The ground is so cold, the satellite thinks they are cloud tops.

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

The HRRR has the high temperatures somewhere around 23 Z, and we will be somewhere in central Missouri around that time.  At least we are headed into a warmer climate.

Today will be bitter cold.  I’m not looking forward to it.  I pumped gas earlier and my car was unhappy about the temperature, as told by the whine of the power steering pump and the sluggishness of the transmission.  The whining of the power steering pump was seconded only by my own whining.  I will need to change a headlight later, and that will certainly be fun.

We are headed towards warmer temperatures, however.  I saw a high of 57 F in Rio Rancho.  I can’t wait to get out of the car in 57 F degree weather again.  It will feel like a tropical paradise.

Thank you for reading my post.
