Bethlehem Live Weather Camera

The coldest air of the season thus far is arriving in the Lehigh Valley, with forecasters touting conditions favorable for snow showers and squalls this afternoon.

Pre-Thanksgiving storm ahead: Your best-laid plans to hit the road for the holiday could be upended next week, forecasters warn.

The Lehigh Valley was among six climate sites in the region that either tied or established record-high temperatures Thursday, but we'll flip the script in a big way next week.

A November-like chill – one that prompted frost warnings for Tuesday morning – will give way to near-record-high temperatures by week’s end, forecasters say.

NOAA's Operational Branch Chief Jon Gottschalck referenced “Snowmaggedon” — the storm that walloped the region in February 2010. He said in this winter outlook, "There’s some hope for snow lovers."

If the Lehigh Valley weather forecast feels familiar, it’s because an end-of-the-week system is once again being watched closely by meteorologists.

A potent system is still on the way to the area, the National Weather Service warned Friday, referencing a storm forecasters have been talking about for almost a week.

"This is something in winter a few months from now … this is a Miller B system [or nor’easter]. The difference is, temperatures are too warm for snow," EPAWA meteorologist Bobby Martrich said.

“The first major synoptic system of the season will impact the region beginning Friday and over the weekend,” the National Weather Service said in its latest forecast discussion.

From low 80s to our first frost? Quiet weather and warm temperatures will dominate the Lehigh Valley forecast this week, but big changes are ahead.

Remember Ophelia? The tropical system that recently brought days of dreary weather to the Lehigh Valley is back. Sort of.

A tropical system that was officially named Ophelia on Friday will drench the East Coast this weekend, including the Lehigh Valley, officials said.

It’s becoming increasingly probable that a subtropical storm develops off the Southeast coast this weekend, forecasters say, but expected impacts to the Lehigh Valley remain in question.

The biggest differences between tropical and subtropical storms are in the way they form and in the broad impacts. A subtropical system could target the region this weekend.

The dry, scorching start to September will slowly begin to ease on Thursday as severe weather takes aim at the Lehigh Valley.

Relief from the brutal heat and humidity has been pushed to later in the week, forecasters say. Wednesday's temperatures will climb into the 90s with heat indexes inching past 100 degrees.

The Weather Prediction Center said one inch per hour rainfall rates are possible, as well as “precipitation totals on the order of 1 to 2 plus inches through the period.”

The middle of August is prime time for ragweed pollen production, according to the state Department of Environmental Protection — and that’s exactly what the numbers are showing in the Lehigh Valley.

It is now certain, forecasters say, that the Lehigh Valley will not see a 90-degree day in the month of August. Not with a pool of Canadian air set to descend on the region.

With a roadmap toward spooky season, the Lehigh Valley’s weather looks to match the fall decor now blanketing stores across the region. Cooler temperatures are on the way.

The National Weather Service warned early Monday of the next round of severe weather taking aim at the Lehigh Valley, and this time it will be a mostly nocturnal event.

A National Weather Service survey team confirmed a tornado touched down in Allentown’s Midway Manor neighborhood Monday night on the east side, but the twister was unwarned.

The National Weather Service rated the tornado as an EF-1 — the second-weakest on the scale. It hit the Midway Manor neighborhood of Allentown and crossed into Bethlehem briefly, according to a weather service statement.

The National Weather Service determined damages during a severe thunderstorm Monday night were from straight-line winds as high as 100 mph, but no tornadoes touched down there.

Neighbors in the Midway Manor neighborhood of Allentown reported seeing a twister as the storm tore through the city's East Side on Monday night. There were no reports of serious injuries, but property damage was extensive.
