WARM WEATHER FOR PHILLY-FINALLY!

It’s been well-advertised that warmer than average temperatures will finally be felt in the Philadelphia area.

The experimental statistical model statistics (EKDMOS) has a temp of about 80, with the possibility of higher (or lower):

By the way, the National Blend of Models (NBM) shows high temperatures of 76 (Friday) and 77 (Saturday).

You can see that on Sunday, 4/15, the range of temperature possibilities is quite large indicating high uncertainty for temperature highs on Sunday.

There’s a high chance of rain on Sunday, especially Sunday afternoon and evening, into Monday.   Some of the rain may be very heavy.

 

PHILLY WEEKEND WEATHER FORECAST

A cold front will move through later tonight with minimal light showers.  Low pressure developing well to our south and moving east over the weekend will provide significant cloudiness for Saturday.

Saturday will be cloudy after some light showers before daybreak.  It will be unseasonably cold, with high temperatures near 45.

There’s a chance of some wet flurries, especially in south Jersey Saturday night.

Sunday will be mostly sunny and continued cold.  High 45.

SATURDAY FORECAST UPDATE- NO SNOW

The evolution of the storm that had been predicted to bring snow to Philadelphia continues.  Lets’s cut to the chase- there’s no snow for Philadelphia on Saturday. Here’s the current model forecast:

The cold front is expected to move through before 8 AM on Saturday morning.  Depending upon your model of choice, either light rain showers (GFS), or close to zero precip (NAM) falls before 8 AM.  Temperatures too warm for snow during the precipitation before daybreak; after the front passes, it will be unseasonably cold for April on Saturday, but dry.

So Saturday is dry after 8 AM.

The front sinks further south and low pressure develops much further south than had been forecast earlier in the week.  Any snow will be much further south than our area.

GFS Forecast
GFS Forecast Saturday night 2 AM

Depending  on the sharpness of the upper air flow, the low pressure may track as a coastal storm that brushes south Jersey Saturday night (GFS) or misses our area entirely (NAM) Saturday night.   It will likely miss us, since I favor the NAM in these situations.
