Update Sun 11:59 AM highlighted below

Friday’s Weekend Weather Forecast had so many updates, it’s difficult to comb through. So here’s an updated Sunday forecast:

High pressure will build back in on Sunday, A flow of increasingly hot and very humid air, typical for the end of June and beginning of July, will begin to affect us on Sunday and beyond. 

Mostly sunny, hot and increasingly humid. (Dew points in the uncomfortable upper 60s to above 70º!) High temp 90.3.º sd 1.3º (NBM Blue Bell)

There’s a chance of early to mid afternoon widely scattered showers northwest (Reading) and in central NJ.

Update Sun 11:59 AM— This morning’s models continue to show the chance of early to mid afternoon showers in central NJ and areas north. The HIRESW models seem to be overstating the rain. But Satellite Water Vapor shows a disturbance moving south that may interact and create some showers.

Temperatures on Monday, Tuesday and Wednesday will be even hotter, with temps 91º-94º with high dew points.


The original forecast for Sunday can be found here.

I’m trying to decide if I’m going out on that bike ride today. The forecast for periods of clouds with light, scattered showers early afternoon still holds. The latest HRRR has the axis of showers more into NJ, while the RAP maintains the track through Philadelphia.
