Flooding Concerns, Hot and Humid Northeast
People flocked to the beach to celebrate the 4th of July yesterday as the heat and humidity climbed across the East Coast.
The setup for the weekend includes a stream of gulf moisture into the Ohio River Valley due to high pressure anchored off the coast and a trough in the central US. This has generated a tremendous amount of rain from the Gulf Coast to the Great Lakes and these persistent showers will continue into the weekend.
The southerly flow along the eastern seaboard is bringing muggy air into the region as dew points this morning were already into the 70s.
Actual temperatures will also be well above average for this time of the year. That combination of the hot and humid air will make the heat indices into the triple digits for Boston and New York.
Heat advisories in effect for the orange shaded counties. From the National Weather Service:
A HEAT ADVISORY MEANS THAT A PERIOD OF HOT TEMPERATURES IS EXPECTED. THE COMBINATION OF HOT TEMPERATURES AND HIGH HUMIDITY WILL COMBINE TO CREATE A SITUATION IN WHICH HEAT ILLNESSES ARE POSSIBLE. AVOID PROLONGED WORK IN THE SUN OR IN POORLY VENTILATED AREAS. DRINK PLENTY OF FLUIDS...STAY IN AN AIR-CONDITIONED ENVIRONMENT...STAY OUT OF THE SUN...AND CHECK IN ON RELATIVES AND NEIGHBORS. TAKE EXTRA PRECAUTIONS IF YOU WORK OR SPEND TIME OUTSIDE. WHEN POSSIBLE...RESCHEDULE STRENUOUS ACTIVITIES TO EARLY MORNING OR EVENING. KNOW THE SIGNS AND SYMPTOMS OF HEAT EXHAUSTION AND HEAT STROKE. WEAR LIGHT WEIGHT AND LOOSE FITTING CLOTHING WHEN POSSIBLE AND DRINK PLENTY OF WATER.
Actual high temperatures in the Boston will most likely be in the upper 90s today but after factoring in all the humidity, it will feel like its in the triple digit.
Further west, the moisture funneled into the Southeast and Ohio Valley is fueling showers and some thunderstorms from Ohio to Florida, with the highest totals coming from the panhandle of Florida.
This pattern is not expected to change so more rain brings flooding concerns to the area. The green shaded counties indicate flash flood watches.
The holiday weekend continues with more warm weather across the Central Plains and the Southwest (although it won’t be as hot as it was last weekend).
Have a great rest of your day and your weekend as well,
