This July 4th weather could put your barbecue plans off
Now, until the July 4th weekend, the forecast says it will still be humid in the south.
“Fortunately, we’ve had a bit of a break for the ground to dry out, but we’re going into a wetter setup,” said Brian Kyle, chief forecaster for the National Weather Service (NWS) in Houston. “Deeper moisture from the Gulf will move through the region, and daytime heating will provide a good chance of showers and thunderstorms each day.”
And this risk of rain will extend to the south and the east coast this weekend. It will be a Wet holiday weekend for millions.
As people head to the beaches for the long weekend, more showers and storms mean more risk.
“It’s a great time with the area’s beaches and rip currents are always a concern heading into vacation week,” Kyle said.
Isolated storms off the Gulf will bring periods of strong southerly winds that could create reverse currents. They could also contain lightning and periods of very heavy precipitation.
“The biggest concern (in the Houston area) is the rate of precipitation, more than the amount,” Kyle said. “Metropolitan areas with a lot of concrete can sometimes have rainfall of 3 inches over an hour, and the ground just can’t absorb it that quickly. And that’s what usually causes flash floods in this part of the world. ‘State.”
While the south struggles with torrential rains, the west does not appear to be able to receive more than a few drops. With 91% of the west in some level of drought, conditions are dire.
“We are talking to emergency officials and firefighters and they say July 4th is their busiest time of the year, due to the likelihood of getting a lot of calls,” said Chelsea Peters, NWS meteorologist. Las Vegas.
Most of the local fireworks are contained within the city and don’t seem to start as many wildfires, Peters said.
However, “the house fires and the trees in the backyard catch fire because it is very dry, so if embers fall, the roofs and trees could catch fire.”
Las Vegas is still waiting for the start of the monsoon season – an annual period of summer rainfall -. Peters is optimistic about the monsoon, but the rains have been so infrequent that it may not be enough to weather the lingering drought.
“Over the past year we haven’t had a lot of weather, especially heavy rainfall,” Peters said. “Looking at the big picture, half an inch here and there is not going to help the deficit we have in the region.”
While places like Seattle will see temperatures drop a bit, the interior of Washington and Oregon will continue to see triple-digit temperatures. It won’t be as hot as last weekend, but temperatures will be at least 20 degrees above normal in some places.
This not only makes it dangerous and uncomfortable, but exacerbates the drought which is already at a critical level.
“We’ve had a few bouts of excessive heat already and summer has just started, which continues to dry up what little humidity we’ve had,” Peters said.
Some jurisdictions are canceling fireworks due to historic drought, to prevent forest fires. Salt Lake City Mayor Erin Mendenhall told residents last week that the fireworks are just not worth the risk this year.
CNN.com will have a full report later this week with everything you need to know before you light any fireworks this weekend.
Seen from space
Between June 2020 and June 2021, the Angeles National Forest went from green and lush to brown and parched. The water in three reservoirs – San Gabriel, Morris and Cogswell – has declined significantly. All reservoirs are outlined in brown in the 2021 photo, indicating how much the water level has dropped.
The Bobcat Fire burned nearly 115,000 acres of the San Gabriel Mountains and parts of the surrounding area between September and December. It was one of the largest fires in Los Angeles County history.
The weekly weather number
115: the hottest temperature recorded in the Pacific Northwest over the weekend.
Pasco, Washington, peaked at 115 degrees Fahrenheit on Sunday afternoon. Pasco’s normal high temperature is 87 degrees Fahrenheit.
The city, which sits on the Columbia River in southern Washington, will see century highs again reach the century today as the Pacific Northwest continues to face record heat. Pasco is expected to stay above 100 degrees Fahrenheit for high temperature throughout July 4th.
Blink and you might have missed it: Tropical Storm Danny formed off the southeast coast on Monday. As fast as it turned, it made landfall and dissipated. The fourth tropical storm of the hurricane season made landfall just north of Hilton Head, South Carolina, around 8 p.m.
While Danny’s impact was minimal, CNN Weather’s Chad Myers says coastal areas in the southeast still face significant beach erosion from Hurricane Matthew, which moved north on along the coast in 2016.
“Any storm surge or high waves can easily cause more erosion and flooding where dunes are still lacking,” Myers said.
Watch out for: The water in the Gulf of Mexico is already 2 degrees above normal for this time of year, which is a favorable environment for tropical storms. There are also two areas of enhanced thunderstorms far out in the Atlantic to watch out for. So far there is no threat to the United States from either of these potential systems. The National Hurricane Center gives one a 10% chance and the other a 10% chance of transforming into a tropical system within the next 48 hours.
The weather of the distant future
Drought in the west is expected to persist for the next three months, in an area already experiencing extreme drought conditions.
Over 55% of the West is subject to “extreme” or “exceptional” drought, with drier than average conditions expected over the next three months.
“Hot, dry conditions only make above normal temperatures more likely, as dry surface conditions (extremely dry soils and below normal or no vegetation) are more effective in heating air temperatures in the area. the lower atmosphere, “said Jon Gottschalck, a meteorologist. at the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center.
Temperatures have been quite extreme for this time of year, with temperatures in the west sometimes 30 degrees above normal.
“Even though it is the end of June, temperatures are preferred to be quite extreme and therefore negative health impacts (dehydration, heat stroke, poor air quality, etc.) are also a risk,” Gottschalck said. to CNN in an email.
“Given the current extremely wet surface conditions in many areas, there are concerns given the precipitation outlook that the already present flooding will continue and the threat of flooding across the region will remain high,” Gottschalck said. .
For these persistent weather conditions to change in the west and south, several things would have to take place.
“The southwest monsoon of the United States is expected to be robust this summer, which will help improve extreme drought conditions in the southwest and parts of the Rockies and the Great Basin,” Gottschalck said. “In 2019 and 2020, the monsoon failed.”
Although there is a forecast for rain for this region over the next few weeks, it is too early to say if it will persist through the summer months.
“At present, however, the information available does not support this scenario,” Gottschalck said.
In the south, the elevation trough that contributed to the persistent thunderstorms is expected to lift northward. This would promote or help a stronger subtropical ridge to extend eastward from the southwest Atlantic to the southeastern coast and gulf region and thus decrease the overall threat of precipitation (fewer events with lower precipitation totals) for the region.
The outlook, however, “does not point in that direction at the moment,” Gottschalck said.
Weather in brief
At least five people have been killed and dozens injured after a tornado hit several villages in the southeast of the Czech Republic, according to local police and emergency service officials. The rare tornado struck Thursday night, wreaking havoc in seven villages and left around 30,000 homes without electricity.
Is a “red sky at night” really a “sailor’s delight”? It’s biblical!
A red sky at sunset can indeed mean good weather. The sun is setting in the west, which is the general direction from which the storms will start. If the sky is red at sunset, it means dry weather is approaching. Reddish tints are usually caused by dust, aerosols, and even smoke that accompanies dry air and takes on a more pinkish tint.
This proverb probably comes from the Bible (Matthew 16: 2-3): Jesus said, “When it is evening, you say, ‘It will be fine, for the sky is red. And in the morning: “There will be a thunderstorm today, because the sky is red and threatening. Can you discern the appearance of the sky, but cannot discern the signs of the times? “
What about the “red sky in the morning, sailors beware?” If it rains, the sun shines on the mid-level clouds to create a red sky in the morning. If these clouds develop further, they could turn into stormy weather – something sailors would be wise to avoid.
