The weather forecast for the weekend has improved somewhat since I posted the “outlook” yesterday. Specifically, Sunday looks to be dry for most of the day.

A blocked pattern that has kept a deep ocean low pressure system to our east is now breaking down somewhat.

The ocean low will progress eastward enough to allow sunshine on Saturday before some clouds move in again later in the afternoon.  High 68-70.

It looks like clouds move in 2-4 PM on Saturday.

An upper air disturbance rotating around a system in the Midwest will spawn weak low pressure that will move into our area, now later on Sunday.  The path of the showers is now further east.

Sunday will have a mix  of sun and clouds in the morning and early afternoon.  Considerable cloudiness is expected during the mid afternoon. High 65.

High level cloudiness (cirrostratus) expected with mid and lower level clouds in the afternoon.

The showers previously forecast in yesterday’s outlook is now forecast to occur late in the day or evening and will be very light and widely scattered.  Heavier showers will develop further east and south of Philadelphia during Sunday evening.
