PHILLY WEEKEND WEATHER

[su_box title=”Saturday Morning Update 8 AM” box_color=”#defcdc” title_color=”#000000″]The forecast is on track with rain starting about 4-5 PM Saturday. High 44.

For Sunday, chance of showers in the morning, then cloudy with a chance of light showers (NBM and GFS) in the afternoon. The NAM continues with a mostly dry and cloudy afternoon. High 63.[/su_box]

Forecast from Friday night:

An approaching low pressure system in the west with it’s associated warm front will pass through our area late Saturday evening into Sunday morning.

Saturday will start chilly with a mix of sun and clouds with temperatures not warming to 40 until noon. Highs will be in the mid 40s during the late afternoon. Clouds move in during the afternoon Saturday and rain starts about 4-5 PM.  Rain will become moderate during the evening and night.

The warm front passes north of us early Sunday morning.  The GFS and the NBM maintain some showers lingering into the afternoon, while the NAM has the possibility of rain ending around noon.  It’s a tough call on whether we’ll have clearing in the afternoon, but I’m feeling the GFS may be holding onto the showers too long.  High temperatures 63-67.

WEEKEND WEATHER OUTLOOK

[su_box title=” Weekend Outlook Update Thursday 7 PM” box_color=”#defcdc” title_color=”#000000″]Weekend Update – Like last weekend, it appears that the rain will arrive sometime mid to late Saturday afternoon. High near 49. Heavy rain Saturday night.

Rain ends during the [late] morning on Sunday. High temperatures about 63 Sunday, but some statistical models are suggesting 67! Updates Friday evening. [/su_box]

The overall weather pattern for Philadelphia over the next two weeks is for below average temperatures (average high about 49) with at least one 3 day warmup occurring over the coming weekend.

Low pressure will bring a southwesterly flow of mild air for Saturday and especially Sunday.  The statistical EKDMOS has a high of 60 for Sunday while the NBM shows a high of 58!

Unfortunately, there’s a high probability of rain for Saturday, but Sunday afternoon may be dry. Too soon to be sure. Stay tuned.
