WEEKEND WEATHER OUTLOOK

[su_note note_color=”#d9f2da”]Updated Outlook in green boxed text[/su_note]

The pattern of very dry weather may be finally ending over the next week.

[su_note note_color=”#d9f2da”]Luckily, next Saturday looks to be sunny and dry.  Sunday may have clouds.[/su_note]

But, before we get to the upcoming weekend…

A cold front associated with a low pressure system near the Great Lakes will move through on Wednesday afternoon.  The models have been cranking out  heavy rain: 1 – 1.5 inches for the immediate Philadelphia area during Wednesday afternoon and early evening.

A dry period from Thursday through Sunday follows with moderating temperatures.

[su_note note_color=”#d9f2da”]Wednesday Update: A coastal low, previously expected to scoot out to our east, may bring clouds and some rain (in NJ) on Sunday, according to the latest GFS model. [/su_note]

More rain early next week.

In the extended range GFS forecast, very cold weather (for October) may arrive a few days before Halloween.

WEEKEND WEATHER OUTLOOK

A blocked pattern has kept a deep ocean low pressure system affecting our weather to our east for several days. The same blocking  has kept an even more robust low pressure system in the upper Midwest.

The ocean low pressure system will gradually progress eastward, allowing much of Saturday to have considerable sunshine before clouds move in again later in the afternoon.  High 68.

The second system in the Midwest will slowly progress eastward and an upper air disturbance rotating around this system will move into our area on Sunday.  Sunday will be mostly cloudy and several runs of the GFS have shown a chance of showers Sunday afternoon.   High 67.

I’ll update Friday evening.
