***FLOOD WATCH FOR MOST OF THE AREA FROM THURSDAY EVENING THROUGH FRIDAY EVENING***


Tuesday was a great looking day with abundant sunshine and a seasonably cold one with highs right around 40 degrees. But looks can be deceiving as brisk and blustery breezes added a chill that made the day feel noticeably colder. Northwest winds gusted from 30 to 40 miles-per-hour for most of us, with Mount Pocono seeing an almost 50 mile-per-hour gust, and those winds helped keep wind chills below freezing throughout the day. Thankfully, winds will diminish overnight but with clear skies and less wind, a perfect recipe for a cold December night will set up as low drop into the upper teens and low 20s throughout the area. 

We’ll keep the sunshine plentiful on Wednesday but as highs inch up a few degrees into the mid 40s and winds remain much lighter, the day will have a much more pleasant feel compared to its predecessor. High pressure will crest overhead and then slide off the East Coast on Thursday, as our next storm organizes to our southwest and prepares to deliver some warmer and wetter weather to wrap up the week. That storm is the only major bump along an otherwise fairly quiet weather road that will take us through Christmas early next week.

We should manage to squeeze in a little sunshine early Thursday but clouds should steadily increase as the day unfolds, with some light rain developing before the end of the day from south to north. That rain will become much steadier and heavy at times overnight Thursday into Friday morning, with a widespread one to two inches of rain resulting across eastern Pennsylvania and  New Jersey. Flood watches have been posted for most of the area for that possibility. Some spots could locally see as much as three inches of rain, especially on the New Jersey side of the Delaware River where the highest rainfall totals are currently expected and where the rain will linger the longest during the day on Friday.

Farther west across Pennsylvania on Friday, the steadier rain should end early in the day as a dry slot tries to develop from midday into the afternoon. There could still certainly be some showers scattered about, but the wettest weather will have shifted east and the afternoon could be at least partially dry. Despite the wet weather, it will also be rather warm with record highs possible not too far from 60 degrees. The number to beat in Allentown is 57°, set in 1957, while Reading’s current record is 61°, set more recently in 2011.  Ironically, Friday is the official start to the winter season, with the winter solstice at 5:23 p.m. Friday evening.

This weekend looks much nicer than our last one, although admittedly we have nowhere to go but up. Both days look a little on the windy side, more so on Saturday, and it will turn seasonably chilly once again with highs in the low to mid 40s. However, it does look largely dry Saturday and Sunday for the last weekend before Christmas.

Then comes the holiday itself early next week, which looks seasonably cold and mostly dry.  A weak disturbance or two could bring a few flurries or a snow shower our way on Monday and then again Christmas night, but no major storms are expected to interfere with your holiday plans. Highs will be in the upper 30s to around 40 degrees, close to normal for late December, as overnight lows drop into the mid 20s, also close to seasonable.

Have a great night!
