Meteorologist Mark’s Severe Wx Concern

Threats

Thunderstorms are possible on Wednesday but it now appears that the severe threat has diminished. Still, I can’t rule a strong storm or two. Overall, the next seven days are looking free of any severe storm threat.

On This Day in Wx History

1967 – Excessive rains in southern California caused the most severe flooding and the most damaging mud slide in 33 years. Downtown Los Angeles received eight inches of rain, and 14 inches fell in the mountains. For perspective, Los Angeles gets about 14 inches of rain a year.

Almanac

Yesterday’s National Temperature Extremes

High: 92° at Rio Grande Village, Texas 

Low: -10° at Peter Sinks, Utah

Tropical Outlook

The tropics are still trying to develop at least one more storm in the Atlantic this season. The chances are low, at this point, but it’s a possibility. The good news is that the system, should it develop, would stay out to sea.

Today’s National Wx Hazards

Accumulating snowfall is likely across Minnesota and parts of Colorado and northwest Montana today. Elsewhere, unsettled weather can be found along a cold front across the middle of the country, but hazardous weather is not expected with that activity.

Tomorrow’s National Wx Hazards

A wintry mix of precipitation can be found across the Northeast, with hazardous driving conditions possible. Accumulating snowfall can be found across the Upper Midwest, the mountains of the Pacific Northwest, and western Colorado. Much unsettled weather exist across the eastern half of the country but severe storms are not a forecast hazard.

 8 – 14 Day Outlook (Nov 28-Dec 4)

A very warm pattern appears to be evolving for much of the northern US for the end of this month and the beginning of the next. Much of they country is trending dry, with the exception of the Deep South and northern New England.

“If you choose not to find joy in snow …. you will have less joy in your life and still the same amount of snow,” Jenny Hagan (@LostInSk). She snapped this picture in Saskatchewan, Canada yesterday.

NASA Nerdology 

Happy belated birthday to astronomer Edwin Hubble, born on this day in 1889. Hubble proved that the universe contains multiple galaxies, rather than just the Milky Way. He’s the namesake of the Hubble Telescope. Hubble would have turned 131 years old yesterday. We sure have come a long way since then!
