Clouds and showers return to Maryland by mid-week
Overnight lows will drop into the upper 50s to mid-60s tonight, just a bit warmer than recent nights due to increased high-level cloud cover. That cloud cover will signal the beginning of a more unsettled stretch.
Onshore flow will strengthen Wednesday night into Thursday as high pressure settles over New England and low pressure develops off the East Coast. This will usher in cooler, cloudier, and more humid conditions for much of Maryland. Low clouds and periods of light rain are likely during this stretch, although the timing remains uncertain. Some weather models show light rain beginning as early as Tuesday morning, while others delay it until Wednesday afternoon.
Temperatures on Wednesday will likely struggle to reach 80 degrees, a noticeable drop from today's warmth, with persistent easterly winds keeping skies overcast.
From Thursday through the weekend, the below-average temperature trend will continue. Highs will range from the upper 70s to mid-80s, with lows in the 60s. While much of this period should stay dry, a stray afternoon shower or thunderstorm can't be completely ruled out.
This pattern will give Maryland a taste of early September, offering a break from the heat and humidity of midsummer.

Wildfire smoke maps show improving air quality forecast for eastern Massachusetts
The sky continues to have a very hazy look to it Tuesday morning in the Boston area as Canadian wildfire smoke affects the air quality in parts of Massachusetts. There are some differences today compared to yesterday. On Monday, there were very few clouds in the area so, any haziness was completely due to the wildfires. Today, we have an abundance of high, cirrus clouds streaming in from the west and southwest. Looking at visible satellite imagery, you can clearly see the brighter white (clouds) mixed with the dimmer, more gray smoke. The National Weather Service has issued an Air Quality Alert for areas north and west of Boston and Worcester for Tuesday. Eastern Massachusetts is no longer included in the alert. Why the change today from yesterday? The predominant airflow at upper levels of the atmosphere remains about the same ... the smoke from the fires in Saskatchewan and Alberta is still largely being directed into the New England. However, at the surface (ground) level, we have easterly winds, off the ocean. That will help to do two things: First, it will mix and dilute the smoky air with some marine air. Second, it will push a lot of the smoke westward, into western New England and New York State (hence why the NWS issued Air Quality Alerts out that way). Therefore, we do not expect these current air quality readings (moderate) to get any worse throughout the day today across eastern Mass. If anything, they may improve slightly. It's the same deal for Wednesday. While the smoke won't completely disperse, an onshore wind will help to keep the airmass in central and eastern Mass. fairly mixed and "clean." The highest concentrations of smoke will remain in western Massachusetts and New York State.

Heat continues to build across Dallas-Fort Worth with plenty of sunshine
Tuesday had a much quieter start with no storms, just a few high clouds and temperatures in the 70s. Yesterday morning, Dallas-Fort Worth International Airport experienced its strongest wind gust on record when a microburst produced an 89 mph wind gust. No significant rain chances are in the forecast for the next several days as high pressure strengthens and shifts back into the area. Today begins a warming trend with highs in the mid-90s, which are still below average for this time of year. Light winds, sunny skies and hot temperatures are all a recipe for another air quality alert today. It will be unhealthy outside for sensitive groups; those with asthma and upper respiratory issues should minimize their time outdoors. As temperatures climb back to near 100 degrees this week, so do "feels-like" temperatures. Heat advisories are likely Thursday into Friday as heat index values climb to 107 degrees.

Japan sets record temperature of 41.8C
Japan logged a new heat record on Tuesday, with the mercury hitting 41.8C, the weather office said, warning temperatures may rise further still. Temperatures the world over have soared in recent years as climate change creates ever more erratic weather patterns, and Japan is no exception. The scorching temperature in the city of Isesaki on Tuesday surpassed the previous record in the Hyogo region of 41.2C, which was set only last week. Tokyo has also been struggling with extreme heat. "I'm really concerned about global warming, but when it comes to my daily life, I can't live without turning on the air conditioner," office worker Mayomi Saito told AFP. "I don't really know what I should be doing. I'm just desperately getting through each day." Last month, 38,608 people were treated in hospital for heatstroke, data showed Tuesday, down from 43,195 in July 2024. Last week there were 18 deaths. In tourist hotspot Kyoto last week the mercury hit 40C, the first time any of its observation points -- the oldest opened in 1880, the newest in 2002 -- had seen such a high, authorities said. Experts warn Japan's beloved cherry trees are blooming earlier due to the warmer climate -- or sometimes not fully blossoming -- because autumns and winters are not cold enough to trigger flowering. The famous snowcap of Mount Fuji was absent for the longest recorded period last year, not appearing until early November, compared with the average of early October. July was also the hottest since records began in 1898, the weather agency said Friday, with the average monthly temperature 2.89C above the 1991-2020 average. Japan's summer last year was the joint hottest on record, equalling 2023, and was followed by the warmest autumn since records began 126 years ago. - South Korea, Vietnam sizzle - Blistering heatwaves have also hit other parts of Asia this summer, from South Korea to Vietnam, as well as Europe. South Korea saw its second-hottest July, with an average temperature of 27.1C, according the meteorological office, which has been collecting such data since 1973. The hottest July on record in South Korea was in 1994, when the average temperature reached 27.7 degrees Celsius. In northern Vietnam, 17 places across seven provinces reported record highs for the month of August, with electricity demand spiking as people try to stay cool, authorities said Tuesday. The capital Hanoi experienced its first-ever August day above 40C on Monday. In Japan, some dams and paddies nationwide are experiencing a water shortage, with farmers complaining that the sizzling heat combined with a lack of rain is slowing rice cultivation. Precipitation in July was low over wide areas of Japan, with northern regions facing the Sea of Japan experiencing record low rainfall, it added. The rainy season ended about three weeks earlier than usual in western regions of Japan, another record. Every summer, Japanese officials urge the public to seek shelter in air-conditioned rooms to avoid heatstroke. The elderly in Japan -- which has the world's second-oldest population after Monaco -- are particularly at risk. This year, western Europe saw its hottest June on record, as extreme temperatures blasted the region in punishing back-to-back heatwaves, according to the EU climate monitor Copernicus. Dangerous weather stretched into the next month, with separate research estimating that climate change made the temperature up to 4C hotter, pushing the thermometer into deadly territory for thousands of vulnerable people and greatly worsening the projected death toll. Firefighters also battled blazes across Turkey, Bulgaria, Greece and Portugal in July following a deadly heatwave. Millions were exposed to high heat stress as daily average temperatures in western Europe climbed to levels rarely seen before -- and never so early in the summer. tmo-nf-aph-stu/lb
