People attending Williamsport's Fourth of July Set the Night to Music celebration may want to bring an umbrella, according to National Weather Service meteorologist Craig Evanego.
The forecast for today and Tuesday calls for highs in the upper 80s to 90s.
"(Today) and Tuesday should both be warm, sunny days - a typical summer-like pattern with a 20-percent possibility of afternoon showers," Evanego said.
Independence Day will be hot with highs in the upper 80s but also with a 40-percent chance of showers and thunderstorms. Locals who are planning to watch the fireworks may want to get their seats early to ensure a clear view.
The increased chance of rain is caused by a weak cold front moving through the area on Wednesday, Evanego said. But he believes the weather won't be bad enough to ruin holiday festivities.
"I don't think it's going to be a washout on Wednesday, but that 40-percent chance of precipitation is worth noting," he said.
In the city, the celebration will begin at 10 a.m., when the Pennsylvania Army National Guard and Young Marines raise the American flag.
Locals will be able to enjoy entertainment from multiple local bands and shop at various vendors from 3 to 10:50 p.m.
A fireworks show will begin at 9:40 p.m. The bursts of color will be choreographed to patriotic music, which will air on multiple local radio stations, including 105.1, 99.3 103.7 and 93.3.
For safety purposes, several city streets will be closed from noon until 11 p.m. They include William, Via Bella, Third, Church and Pine streets. The Market Street Bridge also will be closed from 8:30 to 10:15 pm.
If the rain holds off, locals should be able to enjoy a nice, temperate summer evening.
"It should cool down to the mid 70s right around the time of the fireworks. The heat index will be down into the low 80s," Evanego said.
For the remainder of the week, mostly sunny skies are anticipated, with highs in the low 90s each day.
