Tonight’s models show the southern storm brushing southern Delaware on Sunday.  (Interestingly, the new FV3-GFS had hinted at this all week.)

Sunday will be mostly cloudy with considerable mid and high level clouds. Temperature highs only 36.

[su_note note_color=”#d9f2da”]Saturday morning’s NAM has backed off on the showers in eastern PA but has a slight chance for widely scattered showers in central NJ Saturday morning. Lingering periods of cloudiness in the morning still expected.  [/su_note]

Tonight’s NAM data is just becoming available and it has the front lingering over our area during Saturday morning.  This is a large change in the forecast. So there’s a chance of lingering light, scattered showers during the morning hours tomorrow, Saturday. Skies improve in the afternoon.

(GFS data not available until much later due to daylight saving time, so I can’t compare models at this time)

A weekend forecast  that appeared high confidence, now appears to have some new uncertainty.

This morning’s models haven’t changes significantly. Widely scattered showers are now in Delaware.   The short range models have the rain moving into the immediate  Philadelphia between noon and 2 PM, earlier to the south.   The rain continues into the late evening, heavy at times.

The axis of the heaviest precip shows some variation among the models, with areas just to our south and areas of NJ having the heaviest.   It’s very difficult to pin point the exact placement of the heaviest precipitation.

Sunday is currently looking relatively dry, with only very widely scattered showers; most of the area rain free.
