NORTHERN HEMISPHERE

A lake that dried up 80 years ago looked set on Tuesday to reappear, as monster rainfall accumulated over California's wet winter season overwhelms the state's rivers.In California's Central Valley, authorities issued evacuation orders for residents of communities in Tulare County, where a lake that dried up around World War II was set to reappear.

Spring has sprung: Monday marks the first day of spring in the Northern Hemisphere.

Recipes featuring ramps, morels, rhubarb and other spring vegetables to celebrate the season.

Skies are starting off mostly clear across Lower Michigan with temperatures in upper-20s. There is a fresh pack of snow on the ground after unusual lake effect snow in March over the weekend. The wind was with us all weekend and will continue to blow today gusting over 30 mph across central and southern lower Michigan. As a result, high temperatures will reach the mid-40s to near 50 degrees across central and southern lower Michigan. Winds are weaker as well, which means warmer air will not be able to move into the Peninsula like it will across Lower Michigan.

After the bizarre winter of 2022-2023, the most eagerly anticipated words in southeast Michigan have been “spring begins.”

On March 20 at 5:24 p.m. EDT (2:24 p.m. PDT) the spring (or vernal) equinox occurs as the sun's rays shine directly down on the equator.

Ursa Major, also known as the Great Bear, is the third-largest constellation in the sky. We explore this well-known constellation in more detail here.

We currently have a very active storm pattern with large storm systems stretching across the northern hemisphere. If one or two of these storms take a certain track, southern Lower Michigan could have a real snowstorm. Satellite animation on February 10, 2023 shows numerous storm systems stretched across the Pacific Ocean and aimed at the U.S. This kind of storm track has the first checkmark necessary for a big snowstorm: ample water vapor from the evaporating Gulf of Mexico. If a solid storm system slides through with the cold air in place, we would have a swath of heavy snow across southern Michigan.

The winter solstice is today (Dec. 21), marking the official start of astronomical winter in the Northern Hemisphere and the shortest day of the year.

Whether the weather is wintry or not, the winter season will officially begin in the Northern Hemisphere this week on a day known as the winter solstice. This year the winter solstice will take place at 4:48 p.m. After the winter solstice, the daylight will gradually increase for the next six months until the summer solstice. After the summer solstice, the daylight gradually wanes until we reach the winter solstice, the “shortest day” of the year. The festival of Alban Arthan, Welsh for “Light of Winter,” considered winter solstice a time of death and rebirth, and of soul renewal.

The winter solstice is the shortest day of the year, and happens when the Northern Hemisphere is pointing away from the sun.

The Geminids Meteor Shower is peaking Wednesday morning, with most of the more than 100 bright fragments visible over the Northern Hemisphere, according to NASA.

The summer solstice marks the start of astronomical summer and the longest day of the year. Here we explore when the summer solstice occurs and why.

The climate phenomenon known as La Nina sets off a chain reaction among weather patterns the world over. That can lead to more drought in some places even as it produces flooding and hurricanes in others. La Nina occurs when the surface of the Pacific Ocean along the equator cools and the atmosphere above it reacts. Typically, it happens once every few years. However, the persistence of the most recent case poses the likelihood that the Northern Hemisphere will see its third La Nina winter in a

The record-breaking heat that has pushed California's electrical grid to the breaking point for more than a week is almost over but it's a sign of things to come.

Mercury and the young crescent moon will appear close together in the lower part of the western night sky tonight (Aug. 29). Viewers can spot the duo just after sunset using binoculars.

As we enter the best weeks of summer meteor shower season in the Northern Hemisphere, the conditions are right for witnessing fireballs — a meteor that is larger and brighter than normal. On Sunday, the American Meteor Society, or AMS, received more than 200 reports of a fireball seen in the southern U.S., mainly over Texas, though there were also reports from Oklahoma and Louisiana. The next major annual meteor shower in 2022 is the Perseid meteor shower, which has already started its gradual build-up and will peak during the nights of August 12-13. This year’s Perseid peak will coincide with a full moon, whose light will obscure some of the more faint meteors, but any fireballs will still be visible, according to the AMS. Learn more about fireballs at the American Meteor Society’s Fireball FAQ.

The conjunction will last until Monday and won't be seen again until 2040.

People around the world celebrated the summer solstice today (June 21), as did some satellites in space.

These upper-air pattern changes are common and nothing to be alarmed about. The warm blobs start traveling north and cause a dramatic shift in the whole upper-air pattern around the northern hemisphere. It also means the general temperature pattern we’ve had for the last six weeks will change dramatically next week. The six to 10 day and eight to 14 day temperature forecast shows we will be in a much warmer pattern. High temperature forecast for Wednesday, May 11High temperature forecast for Thursday, May 12High temperature forecast for Friday, May 13Many of us have been waiting for the coming extended warm weather after a stretch of gloomy, cool weather in late March and April.

Winter solstice arrives today, bringing the longest night to the Northern Hemisphere.

The winter solstice is when the Northern Hemisphere is tilted farthest away from the sun — bringing the shortest amount of sunlight of the year.

Today is the winter solstice: The first official day of winter in the Northern Hemisphere. The solstice also marks the longest night of the year, because it is the date with the least amount of daylight hours. And, day by day, the sun will trace an ever-higher path across our southern sky.”According to the U.S. National Weather Service, on Tuesday, the sun will reach its southernmost position "above" the earth on its annual cycle — marking the winter solstice. | Photo courtesy U.S. National Weather ServiceThe sun has been held sacred to many cultures across history, which is why both the summer and winter solstices have long played important roles in folklore and traditions. Ancient Romans marked the winter solstice through the seven-day Saturnalia festival, which honored the Roman god of agriculture and harvest, and was characterized by the suspension of discipline, according to the Farmers’ Almanac.

Winter Solstice has long marked a time of rebirth, behind it are fascinating astronomical events

October's full Hunter's Moon, the first full moon of fall in the northern hemisphere, will reach its peak at 10:57 a.m. EDT (1457 GMT) today (Oct. 20), and remain big and bright in the night sky through Thursday.

The big driver of a several-week weather pattern is the upper-air flow. We are going to look at the wind flow at around 15,000 feet up around the northern hemisphere. And yes, as the globe warms, the warm high pressure ridges may get stuck in different areas from decades in the past. One such trend seems to be a winter warm ridge over Greenland. But for now just know the way the upper-air pattern is configured across the hemisphere will make the Great Lakes region and Michigan warmer than normal for at least the next few weeks.

September's equinox has arrived today, marking the beginning of astronomical autumn in the Northern Hemisphere, where the nights will get longer than the days until the spring equinox in March 2022.

Thanks to its Latin name meaning "equal night," the equinox is often thought of as the day when dark and light each claim 12 hours, but that's not the case.

The harvest moon is the last full moon of the summer. This year it will appear to be full for three days with peak illumination occurring at 7:54 p.m. ET Monday.

The official start of summer kicks off in the Northern Hemisphere today (June 20) to make Father's Day the longest day of the year.

For those of us in the Northern Hemisphere, this weekend marks the summer solstice -- the official kickoff to the summer season and the longest day of the year, meaning it has the most hours of daylight. This year summer solstice is Sunday, June 21 at 03:32 UTC (that’s 11:32 p.m. EST). After reaching that peak, the sun will begin moving back south along the horizon until it reaches its lowest point at the winter solstice. But even though modern culture may be more removed from nature than our predecessors, the natural pause of the solstice still presents an opportunity to reflect, connect, and get present with the natural world, Adams says. “The more we try to emulate the harmony of the natural world, the greater harmony we have in our own lives,” she says.

Chicagoans witnessed a partial eclipse of the sun on Thursday morning, opportunely timed with the announcement of Adler Planetarium’s partial reopening.

(Randall Irmis via AP)Plant-eating dinosaurs probably arrived in the Northern Hemisphere millions of years after their meat-eating cousins, a delay likely caused by climate change, a new study found. A new way of calculating the dates of dinosaur fossils found in Greenland shows that the plant eaters, called sauropodomorphs, were about 215 million years old, according to a study in Monday’s Proceedings of the National Academy of Sciences. So far, scientists haven’t found any example of the earliest plant-eating dinosaur family in the Northern Hemisphere that’s more than 215 million years old. The plant eaters “were late comers in the Northern Hemisphere,” said study lead author Dennis Kent, of Columbia University. That highlighted the migration time gap, said several outside experts both in dinosaurs and and ancient climate.

With this year’s winter solstice comes more than just confirmation of our already-cold weather and ever-fleeting daylight: The rare “Christmas Star” will be visible for the first time in 800 years. Each year, Earth’s northern hemisphere enters the winter solstice on Dec. 21 -- the shortest day of the year -- officially marking the start of winter. This year, bright planets Jupiter and Saturn will align perfectly on Dec. 21 to create what is commonly called the Christmas Star or the “Star of Bethlehem.”According to NASA, Jupiter and Saturn align with one another every 20 years or so, but not nearly as close together as they will be in 2020. Experts say the Christmas Star can be seen by the unaided eye just after sunset on Dec. 21, 2020. You can see Saturn and Jupiter nearly align on Dec. 21, forming what appears to be a Christmas star.

GENEVA – For all the recent talk of global warming, climate historians hunting for past temperature extremes have unearthed what the U.N. weather agency calls a new record low in the Northern Hemisphere — nearly -70 degrees Celsius (-93 F) was recorded almost three decades ago in Greenland. The World Meteorological Organizations publicly confirmed Wednesday the all-time cold reading for the hemisphere: -69.6 Celsius recorded on Dec. 22, 1991 at an automatic weather station in a remote site called Klinck, not far from the highest point on the Greenland Ice Sheet. “In the era of climate change, much attention focuses on new heat records," said WMO Secretary-General Professor Petteri Taalas in a statement. The new low was confirmed by so-called “climate detectives” working with the WMO's Archive of Weather and Climate Extremes in Geneva. The coldest temperature ever recorded on Earth was the -89.2 Celsius (-128.6 F) recorded in 1983 at the high-altitude Vostok weather station in Antarctica, WMO said.

Ordinarily, South Africa sees widespread influenza during the winter months, but this year almost none have been found something unprecedented. But theres no guarantee the Northern Hemisphere will avoid twin epidemics as its own flu season looms while the coronavirus still rages. This could be one of the worst seasons we've had from a public health perspective with COVID and flu coming together. The evidence: Ordinarily, South Africa sees widespread influenza during the Southern Hemisphere's winter months of May through August. In the United Kingdom, Prime Minister Boris Johnson likewise is urging widespread flu vaccination.

'Fall leaf' colors actually exist all year longNow, don't get too excited. Oh, fall leaf tourism brings in BIG MONEYIt's called "leaf peeping." Fall is only 'fall' to Americans, even though the term was coined in BritainWhat do you call the picking of ripe sweet potatoes, squash and pumpkins? Some time after, poets coined the phrase "the fall of leaves" -- shortened to "fall" in the 1600s. By the mid-1800s, the word "fall" had firmly rooted itself in America.
