Another day with showers, thunderstorms and humid conditions. When will the rain end?

• The Lehigh Valley has endured four consecutive days of rain, and more is on the way
• Monday will feature a "parting shot" from a stalled front, forecasters say
• Tuesday into Wednesday will bring more unsettled conditions

BETHLEHEM, Pa. – A stalled front will take a parting shot at the Lehigh Valley on Monday, bringing additional showers, thunderstorms and possible downpours to parts of the region.

“[It’s] the stalled boundary that’s just never going away. It’s endless,” joked EPAWA meteorologist Bobby Martrich in his Monday video forecast.

It comes after four consecutive days of rain, with precipitation reports showing anywhere from 1.71 inches (measured in that time frame at Lehigh Valley International Airport) to one-day totals that reached nearly 3 inches in parts of Bucks County on Sunday.

“The boundary is going to be in a much weaker state than it has been over the past couple of days,” Martrich said, while noting that a “parting shot” could bring showers and isolated, garden-variety thunderstorms to the area.

A few more days of humid, unsettled conditions

According to the National Weather Service, a stronger cold front will approach our region from the west later Tuesday and Tuesday night, then work its way across the area Wednesday.

“It is this front that will bring relief from the days of convection and humid conditions,” the NWS forecast discussion said.

The timing — overnight Tuesday into Wednesday — should help limit any possibility of severe weather, as instability will be limited.

“It does appear a broken line or clusters of showers and some thunder arrives early Wednesday morning, then some additional convection may occur through the afternoon as the cold front or perhaps a secondary one moves through,” the forecast discussion noted.

The main impact Wednesday would be the potential for localized flash flooding from downpours, especially for areas that have already picked up excessive rainfall amounts over the last four days.

Long-range outlook brings relief

Drying is expected to start overspreading the area by Wednesday night, and forecasters say the long-range outlook also features below average temperatures and dew points in the comfortable range.

Temperatures for the back half of the week and into the weekend show highs in the low to mid 70s and overnight temperatures in the 50s.
