Threat for a downpour or a t-storm lingers through this evening

Drying out and heating up Wednesday

TODAY: Humid with clouds and some periods of sun; showers and a t-storm could trigger localized flooding. High: 80

TONIGHT: A shower or a t-storm in spots; otherwise, partly cloudy and humid with fog developing late. Low: 68

WEDNESDAY: Partly sunny, hot, and moderately humid. High: 90



Happy Tuesday! One day closer to Friday, and fewer flood watches and warnings to track on the weather map compared to yesterday. Let's talk about yesterday for a minute... Monday's radar estimates and automated gauges had parts of the region receiving 4.0" to 6.0" over in 24 hours. That's on top of elevated rainfall totals for the month of August, which has both Allentown and Reading more than 5.0" above normal. This lead to multiple flash flood warnings being issued, and trouble finding a way to work or home. 

While there will still be a few showers and a thunderstorm around through this evening, we're not forecasting widespread flooding like what we see Monday. With that said, it wouldn't take much more than a quick downpour to trigger localized flooding. The pesky area of low pressure, and the upper-level low accompanying it, responsible for swollen waterways will slowly drift to the northeast over the next several hours, eventually losing its firm grip on the region. That means peeks of sunshine are more than possible, but promised. Diminishing clouds overnight will act as the third ingredient in a healthy fog recipe, with the other two being recent rainfall and calm winds. You might want to leave extra time to get to work Wednesday morning. 

High pressure will briefly slide across the region on Wednesday and the first half of Thursday giving us a break from the rain and, at least on Wednesday, a slight dip in the humidity. That means flooding will take a back seat to heat as sun-kissed temperatures flirt with 90 degrees.

The threat for showers and a thunderstorm will return late Thursday and stick around as we wrap-up the work week on Friday. However, that's not the only thing sticking around as daytime highs will once again approach 90 degrees despite the uptick in rain chances. It won't be as hot for the weekend--or as unstable. Most of the time it's dry with spotty shower or storm around. Highs will be in the middle 80s.

Wishes for a productive work day!
