Locally Expect Fog, More Rain, Then Icing Worries
MOUNT HOLLY NJ – For the short term, the Philadelphia area office of the National Weather Service says western Montgomery County drivers must worry first about dense fog conditions that could last through Thursday (Feb. 3, 2022) at 11 a.m. After that, Friday will be mostly a rain event with local flooding possible, it said. Its real concern for traffic, however, is frozen roads Saturday (Feb. 4) morning.
The weather service is predicting dense fog across the area through Thursday morning, which “will result in visibilities (of a) quarter-mile or less.” It may be difficult for drivers to see much of what’s ahead of or behind them. The weather service urges caution and slow speeds through mid-day.
“Periods of moderate to locally heavy rain will develop Thursday, and between 1 and 2 inches of rain will fall through Friday,” it added. “This, combined with rapid snow melt, will result in localized flooding, especially in portions of southeast PA,” the weather service reported.
Its kicker? “Any standing water on area roads is likely to freeze as temperatures plummet below freezing Friday night. Up to a tenth of an inch of ice is possible in southeast PA, and northern-most and often colder parts of Montgomery County could experience up to a quarter-inch, according to the latest weather service briefing.
