The Northeast will finally get some relief from the hot temperatures as a slow moving front will bring rain. However, some of the storms ahead of the front will be severe, with the primary threat being damaging winds. The Storm Prediction Center has issued a slight risk (level 2 out of 5) for Philadelphia, Baltimore, charlotte, and Washington. Flooding will also be a concern Wednesday morning as the frontal boundary passes.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-09 040836-1752055729704.png">The flood watches come after Chantal, a Tropical Storm that produced heavy rainfall across the Carolinas, therefore some of these areas are already saturated. <img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-09 041120-1752055892540.png">The forecast calls for an additional 3-4 inches of rainfall in the next 3 days for locations in central Virginia. Also, 2-3 inches of rainfall will be possible from Delaware to the Jersey Shore and across central North Carolina. Multiple waves of storms and high rainfall rates mean flash flooding is possible.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-09 042625-1752056839301.png"><h1>Severe Outlooks</h1>Severe weather outlooks have been issued for the next three days as a cold front moves into this hot and unstable air mass. With the loss of daytime heating, the severe threat is now marginal. On Wednesday, as the front slides east, the risk is SLIGHT (level 2 out of 5) for severe storms across the Carolinas, Virginia, Maryland, and Delaware. On Thursday, the SPC expanded the MARGINAL risk from New England through Georgia.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-08 135520-1752004747455.png">Friday the SPC keeps a MARGINAL risk around for Washington, Roanoke, and Columbia.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-09 041249-1752056041320.png"><h2>Timing</h2>Storms will happen along and ahead of the frontal boundary. Over the next few days, strong to severe storms can develop, and during peak heating is when the risk for damaging winds and large hail will be the greatest.<video src="https://media.weathernationtv.com/app/uploads/2025/07/2025-07-09 04-14-40-1752056136088.mp4" controls="true" width="100%"></video>Tune into WeatherNation :10 the hour for the Eastern Regional Forecast for more details.

Energy spinning off the Rockies is forcing the development of strong to severe thunderstorms.<h2>SEVERE OUTLOOKS:</h2>WednesdayThe SPC has issued a marginal to slight risk for severe storms in portions of the Plains on Wednesday as a cold front dives south. The best timing for severe storms will be during peak heating towards the afternoon and evening.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-09 042047-1752056459170.png">ThursdayA slight risk for severe weather includes the Plains and Northern Plains. Large hail and damaging wind are possible.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-09 042111-1752056482771.png">Storms developed on Tuesday, and will continue to follow a frontal boundary as it moves south and east. The plains and Midwest will be active over the next few days.<video src="https://media.weathernationtv.com/app/uploads/2025/07/2025-07-09 04-21-36-1752056529933.mp4" controls="true" width="100%"></video>Flooding could become an issue, especially if storms get hung up trying to press south tonight. The greatest risk for something like that would be in eastern Oklahoma or portions of Arkansas.

WEST - Heat alerts have been issued across the western U.S.. The cause of this heat wave is an upper-level ridge building in from Mexico. This will be responsible for the intense heat in the southwest.Heat advisories (orange), extreme heat warnings (pink), and extreme heat watches (red) have been issued for portions of California, Nevada, and Arizona through Thursday. Temperatures may rise to 110-116°F in some of these locations. Too hot for the human body to handle. Unfortunately, heat is the deadliest weather phenomenon in the USA.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-09 041818-1752056317453.png">Here's a look at our forecasted temperatures in comparison to the average.

Tropical Storm Chantal formed Saturday morning and made landfall early Sunday morning with sustained winds of 50 mph. Winds have knocked down some palm fronds and lead to a foot or two of storm surge so far. Chantal turned into an inland flooding threat, especially in North Carolina.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-07 073731-1751895631663.png"><img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-07 074408-1751895856913.png"><h1>Forecast</h1>The remnants of Chantal will continue to move Northeast and eventually get picked-up by an inbound cold front and carried back out to sea. Until that happens, efficient rainfall could produce some localized areas of flooding Monday. <video src="https://media.weathernationtv.com/app/uploads/2025/07/tomer chantal futurecast-1751848909743.mp4" controls="true" width="100%"></video>A narrow band of heavy rain accumulation is possible through Tuesday morning.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-07 074157-1751895727202.png">Catch more details on the southeast during your Southeastern Regional Forecast, :10 past the hour on WeatherNation.

Following the prolific start to the season, the Eastern Pacific remains quite active as the National Hurricane Center is tracking two different areas of interest southwest of Mexico. Invest 96E or the orange highlighted area has a medium chance of development in the next couple of days. The chances have backed off as it appears less likely that something will come together. The region outlined in yellow is quickly falling apart with 0% chance of development.<img src="https://media.weathernationtv.com/app/uploads/2025/07/tomer tropics epac-1751913671695.jpg">The spaghetti plots show 96-E remaining well south of Mexico as it churns westward. This will limit impacts to the west coast of Mexico but interests in Hawaii should keep an eye on this system for the potential of increased rain chances next week.<img src="https://media.weathernationtv.com/app/uploads/2025/07/tomer e pac spag-1751848680670.jpg">This system could bring stronger currents to Mexico's coast, but if it remains weak before moving farther west impacts should be minimal.<video src="https://media.weathernationtv.com/app/uploads/2025/07/tomer e pac futurecast-1751848767502.mp4" controls="true" width="100%"></video>For more details on this forecast, be sure to check out the <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.nhc.noaa.gov/text/refresh/MIATCPEP1+shtml/020252.shtml">National Hurricane Center's </a>website.

Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

AAA is expecting over 70 million travelers to take to the roads and skies over the Fourth of July Weekend. Unfortunately, heavy rainfall could throw a wrench into those plans, as slow-moving systems keep rain chances around.<img src="https://media.weathernationtv.com/app/uploads/2025/06/Screenshot 2025-06-30 073837-1751290861562.png">After a hot work week, especially out west, the temperature for the 4th of July will be near seasonal for many.

NORTHEAST -A shortwave trough will swing through the Great Lakes and into the Northeast on Thursday, bringing the threat of afternoon thunderstorms along an advancing cold front. Warm and humid air ahead of the boundary will help fuel the risk for damaging wind gusts and isolated hail.The SPC has issued a SLIGHT (level 2 out of 5) risk for severe storms in these areas.<img src="https://media.weathernationtv.com/app/uploads/2025/07/PIC 1-1751573415086.jpg">Storms look to start during the day in New York State, but the frontal boundary doesn't move towards the I-95 corridor and clear until later into the evening/nighttime frame.<video src="https://media.weathernationtv.com/app/uploads/2025/07/2025-07-03 05-06-29-1751540825848.mp4" controls="true" width="100%"></video>This next frontal boundary is coming just a couple of days after significant flash flooding happened in the northeast, so the flooding threat where we have already seen rain may be more sensitive to flash flooding through the end of the week.<img src="https://media.weathernationtv.com/app/uploads/2025/07/Screenshot 2025-07-03 042835-1751538519921.jpg">

Northeast Severe Threat on Thursday

PIC1jpg-1751573435140.jpeg

How strong is the jet stream? Enough to take a standard National Weather Service upper-air observation balloon on a journey nearly a thousand miles!

https://twitter.com/weatherdak/status/966741182532304896

Twice a day, every day NWS offices across the country launch radiosondes, or balloons with attached weather observing instruments. Scientists use the data collected as the balloon travels upwards in the atmosphere to build vertical profiles, which are essential to understanding the structure of weather systems. When collected at a large number of locations, upper-air observations help establish the initial conditions for computer models that forecast weather and climate conditions.

On Thursday morning, the NWS office in Fort Worth, TX received word that one of their balloons got caught up in the powerful jet stream of the current storm system and traveled all the way to Dexter, MI. That's nearly 1,000 miles away!
