This will have to be very brief. My NWS is coming to a close and I have been swamped in that preparation.
The expected cold mentioned in the previous post has come to fruition and will culminate with brutally cold and wind Thursday and into the early weekend. Any meaningful snow will concentrate on the midwest but won't help in any drought concerns as it will be very dry. The biggest issue will be the cold (actual temperatures and wind chill indices), as shown below.
The upper air pattern is ideal with the cold buildup across the higher latitudes of North America and is being unleashed south as the blocking high had developed across Greenland. Here is the upper air map as of this morning...
Expected temperatures Friday morning (and keep in mind Thursday temperatures will not be much warmer and wind chill indices will be extremely cold)...
Warmer weather is expected the last few days of December. January - I need to find some time to look it over.
BTW, here is a map of precipitation that occurred yesterday by a little weak weather system.
I'm not sure I will be able to update until after the first of the year - as a Non-National Weather Service but as a consulting Meteorologist. Changes are coming!
