Weather map shows arctic heat and cold records

Posted:
Update:

The high temperature on Christmas Day in Grand Rapids was 52 degrees. This happened at 2:40 a.m. It was the hottest Christmas day in GR since reading 59 ° in 2015. The hottest Christmas ever in GR was 65 ° in 1982. We had a thunderstorm and an inch of rain that day . I also picked a dandelion in my front yard. We had 5 days in December 1982 with high temperatures in the 60’s. A year later, in 1983, we had our coldest Christmas at -3 °.

The map above shows high temperatures for Saturday (Christmas Day). It was colder as you head northwest… the high was only 16 at Duluth and I’m glad I didn’t spend the day in Saskatoon, Canada. Very cold air covers much of central, northern and southwestern Canada. Vancouver, British Columbia had its first White Christmas in 13 years. By mid-afternoon, it was snowing with temperatures hovering around 30 in Seattle. San Francisco had a small thunderstorm with a temperature. of 49. The cool air plunges south into the desert, where the forecast for Phoenix AZ indicates high temperatures of the mid-1950s to 60s over the next 7 days.

Record temperatures were the rule from Texas to the Ohio Valley. Among the records on Christmas Day: 84 in Houston, 82 in Dallas (the average high is 56) and 77 in Poplar Bluff, Missouri. Louisville KY reached 75 and Cincinnati (Lufkin) climbed to 70. Indianapolis missed its Dec. 25 record by just one degree. (63.)

Christmas Day High temperature record by state

This map from the Weather Prediction Center is a preliminary look at the highest temperatures on record for Christmas Day by state. New state records for December appear to have been set in AK, MO, IN, IL, and TX. Now keep in mind that several factors are important here. One is the accuracy of the reading. I noticed that all of a sudden Rio Grande Village TX appeared to be the hottest temperature in the United States very often. Here is a check on other high temperatures. in southwest Texas. There was a 93 ° from the mesonet weather station near Castolon. The next highest reading after that is 88 °. I would be interested in the location of the Rio Grande Village weather station, the quality of the suction (the fan blowing air through the station if that’s the design), the distance between the weather station and the buildings, etc. Then there is a question of the length of the data. It is much easier to set a record high temperature for when you are 25 years high as opposed to a 150 year record. From the NWS: “Even using xmACIS2 it wasn’t easy. Co-op sites report in the morning, which means the values ​​for December 25 could be 24. Airports / NWS offices report midnight to midnight LST. There could be some undetected errors with the graph.

The cold air is getting closer. BAMWX also sings a cooler tune for early January.

Storm Forecast Center Severe Weather Outlook Map

Isn’t that a weird card… it’s the thunderstorm outlook for PM / night. Severe weather is not expected, but some unusual places could hear thunder today. The first perspective covers almost all of Illinois and Indiana – and stretches across southern Wisconsin and southwestern Michigan. It would be mainly for Sunday evening – not during the day. The second viewpoint is on the West Mountain and the third is along the West Coast.

Fire hazard December 26 – Sunday

Fire hazard for the southern high plains this PM. A combination of dry soil, low humidity and strong winds increased the risk.

Evening planets

This GR NWS chart shows the planets that adorn our evening sky right now. Venus descends in the WSW after sunset. It is a croissant, even if it seems round to you. It will continue to move closer to the horizon at sunset as we move through the winter. Jupiter and Saturn are much bigger than Venus, but they are much further apart. Saturday night we had a waning moon (less and less of the moon is visible each night) that was about 2/3 full.

ALSO: Phoenix AZ has had its wettest Christmas Eve in 80 years. Flagstaff and Phoenix recorded total precipitation of at least an inch during the 24-hour period Friday night. Another snowstorm from North Dakota to Upper Michigan. I have walked several times on this beach. Beautiful snow in Colorado. Christmas double rainbow. The number of sunspots is increasing. White Christmas in Western Washington. Volcano-nados! Tornadoes hit Alabama on Christmas Day in 2012. The first snow of the season fell in Tokyo about 10 minutes after Christmas Day ended. The chance that Tokyo will see a White Christmas is less than 5% based on data from 1961 to 2017. -40 wind chill factor in Montana. Snow on the coast of British Columbia.

Arctic Air moves across the northern plains

Arctic air moves across the northern plains… getting closer to western Michigan. Lake Michigan is open water with a water temperature. almost 40 degrees. We are still looking at the possibility of lake effect snow. The NWS takes Green Bay to + 4F… quite cold.

And… you can own the car that Jimmy Stewart rammed into a tree while filming “It’s a Wonderful Life?” Sam Wainwright’s car was a Duesenberg SJ city limousine. Ralphie’s father’s car in A Christmas Story was a 1938 Oldsmobile touring sedan.
