Meteorologist Mark’s Severe Wx Concern

Threats

My concern is unchanged from yesterday and remains on the low end of the threat scale. The Storm Prediction Center has placed our region in the marginal risk for severe storms, which is the lowest of the threat levels issued by them. The main threat is a damaging straight-line wind gust along a line of strong storms that will cross the plateau this evening. The main threat timeframe is 6:00 – 10:00 pm. This is not a widespread severe weather event, but an isolated severe storm is possible. I’ll keep you posted!

On This Day in Wx History

1950 – A great storm hit the northern and central Appalachians with snow and high winds. Winds reached hurricane force along the eastern slopes of the Appalachians, with gusts to 100 mph at Hartford, Connecticut. The winds on Mount Washington in New Hampshire hit 160 mph! Heavy rain also hit the eastern slopes, with eight inches reported at Slide Mountain, New York. The western slopes were buried under heavy snow. The storm produced record snowfall totals of 27.7 inches at Pittsburgh Pennsylvania, and 36.3 inches at Steubenville, Ohio. The snow and record-cold temperatures resulted in 160 deaths.

Almanac

Yesterday’s National Temperature Extremes

High: 94° at Rio Grande Village, Falcon Lake, & Zapata, Texas 

Low: -16° at Peter Sinks, Utah

Tropical Outlook

The National Hurricane Center continues to monitor an area of low pressure in the Atlantic. The system still carries a 30% chance of developing into a named storm. Whatever happens, the system will be staying out to sea.

Today’s National Wx Hazards

A strong storm system will bring unsettled weather to much of the eastern US today. Some of the storms along the cold front could be strong to severe. Meanwhile, snowflakes are flying across the northern Rockies and some of that will be accumulating.

Tomorrow’s National Wx Hazards

Unsettled weather remains along the East Coast and Gulf Coast, but hazardous weather is not expected. Folks across northern Idaho/western Montana, western Colorado and northern Arizona will have a white Thanksgiving!

 Weather Shots

Strong to severe storms rocked parts of the southern plains yesterday. This was the scene just west of Oklahoma City yesterday evening. Bart Comstock (@SvrWxChaser) captioned this photo he took by writing, “Insane whale’s mouth moving down I-40 right now west of OKC. Absolutely gorgeous!” A “whale’s mouth” is a weather slang term for clouds with this appearance. Impressive looking skies, to say the least!

NASA Nerdology 

During this final week of November in 2015, mathematician Katherine Johnson was presented with the Presidential Medal of Freedom. NASA noted, “Johnson’s work at NASA helped make our first endeavors into spaceflight possible, and we will never forget her courage and her leadership.” A wonderful honor for a wonderful lady.

You all have a great day!
