CBS News20-07-2025
After a more gray day on Saturday, the Philadelphia region is seeing the best chances of overnight showers and storms to our south.
There was a lot of lightning associated with the storms across Maryland, so we'll be watching for perhaps one or two of those making their way closer to Delaware.
Sunday will give us mixed skies with a trend for much more sunshine than Saturday.
With the instability in the air, we cannot rule out an additional shower or rumble, especially in the late afternoon. Severe weather is likely to stay mainly north and east of the region, but we'll keep an eye on it.
Monday through Wednesday, much drier, cooler and more pleasant conditions arrive behind the cold front.
Skies will be sunny, humidity will be low, and highs will only reach the low to mid-80s. These may be some of the nicest days so far this summer.
By Thursday, we warm to the 90s again, and on Friday, another chance of storms is in the forecast.
Sunday: Shower, storm. High 91, Low 74.
Monday: Much nicer. High 87, Low 71.
Tuesday: Sunny and dry. High 83, Low 65.
Wednesday: Sunny skies. High 86, Low 65.
Thursday: More humid. High 91, Low 67.
Friday: Partly cloudy. High 95, Low 73.
Saturday: Partly cloudy. High 94, Low 77.

Tampa Hits 100 Degrees For The First Time In Recorded History

More America/Universal Images Group via Getty Images) On Sunday July 27, 2025, Tampa, Florida reached the 100 degree F mark for the first time in recorded history. I am sure this comes as a surprise to many readers who have spent any time in central Florida. Certainly, some of you are saying, 'How can this be? It is hot in Florida in July.' Let's dig a bit deeper into this stunning piece of weather and climate history. Tampa, Florida hit the 100 deg F mark for the first time in recorded history on July 27, 2025. At 3:30 pm Sunday, the National Weather Service in Tampa Bay wrote, 'Tampa broke the all-time high temperature record today 100 degrees F!…. The old record was 99 degrees F last set on June 26, 2020.' Temperature records have been taken since 1890 in that location. I emphasize that because it is likely you will see a few headlines that say, 'For the first time ever.' The NWS Tampa office is located in Ruskin, Florida. It would not surprise me if temperatures were even hotter in the highly urbanized parts of the region. Temperatures expected in central Florida this week. Central Florida always feels hot in July, and it is. But it has never, hit an official air temperature recorded in triple digits. The average high temperature at this time of year is in the low nineties. Temperatures in the region rarely exceed 95 degrees F, but the humidity can certainly elevate the 'feels like' apparent temperature or heat index above 100 degrees F. Now imagine 100-degree air temperatures and the humidity. Though not the focus here, studies continue to confirm that as climate warms, the intensity and frequency of heat waves is changing too. This presents challenges for people using old heat benchmarks like their childhood as a reference point. This is not your grandmother's heat. Temperatures through the middle of the week will remain oppressive in Florida, and I would not be surprised if a few more records fall. Why is it so hot? A dominant high-pressure system is bringing historically-hot conditions to the entire southeastern U.S, and it will persist into the first part of the week. Many media outlets have fallen in love with the term 'heat dome,' but as a meteorologist, I prefer to explain it in terms of meteorology and physics. Weather map on July 27 depicts high pressure over the U.S. South. If you see that terminology, it is referring to an extensive area of high pressure and warm temperatures. The dome of high pressure is often associated with sinking air that contributes to hot, dry conditions. The sinking air warms through something called adiabatic compression. In the absence of rising motion, rainfall-producing clouds are limited under these conditions. A heat dome. Tampa Bay is strongly influenced by its proximity to water. The Gulf has several influences on local weather and climate. It is a source of moisture that contributes to very humid conditions. It creates microclimates like the sea breeze circulation. Because the land warms up faster during the day, a sea breeze moves in from the water. The sea breeze often produces clouds and rainstorms. At night, the breeze system can reverse as land cools faster than the water. Such circulations happen because water has a larger heat capacity than the land. It's the same reason sand is hot on a May beach day, but the water is still cool. Locations closer to the coast also have smaller temperature ranges.

Sunday afternoon Chicago storms prompt ground stop at O'Hare International Airport

Another day of storms has prompted a ground stop at O'Hare International Airport. There was no rain falling in downtown Chicago as of 4:30 p.m., and Midway International Airport was not affected. But the Federal Aviation Administration said there was a ground stop due at O'Hare due to thunderstorms. The National Weather Service said isolated and scattered storms would develop through the afternoon, with the relatively highest coverage in the Chicago area along the lake breeze. Downpours, lightning strikes, and gusty winds are among the risks.

San Francisco sets record for rainiest July week since 1850, adding to its unusual summer

San Francisco has officially tied its record for the number of days with rain in July, and it did so in a record-breaking way. July is typically the driest month of the year. And while it is normally foggy in downtown, it doesn't average more than .01 inches of rainfall for the entire month. This year, however, there have been five days where measurable rain fell in downtown San Francisco, tying the old record of rainy days from 2022. But what makes 2025 stand out is that all the rain fell in the past week: July 21, 22, 25, 26 and 27. That makes the past week the rainiest July week ever recorded in San Francisco, and the records go back to 1850. So far, .08 inches of total rain has fallen this month, tying for the 11th wettest on record. It isn't a lot, but San Francisco usually averages .01 inches for the entire month. With what has been an unusually cold summer, San Francisco could yet break the record for the most rainy days in July.
