Thursday -Rain looks like it will wait
Posted Thursday 04/10/25 @ 10:29 AM — In contrast to some of the forecasts I’ve heard this morning, based on the experimental RRFS and the AI version of the ECMWF, it really looks like any rain here in the immediate Philadelphia area will occur AFTER 5 PM and perhaps not even during the evening hours. Any rainfall we do receive today looks to be very light.

Posted Wednesday 04/09/25 @ 11:41 AM — Depending on the model, it appears that rain will move in Thursday evening and will be on and off through Friday. Rain picks up in intensity later Friday evening as low pressure develops near the coast and likely lasts through much of Saturday.
A closed upper and mid-level low pressure system will remain over our area through the weekend. Cooler than average temperatures and unsettled conditions are likely.
The experimental RRFS model is handling Friday night quite differently compared to the ECMWF-AI model; the RRFS has a prolonged break in the rain later Friday afternoon into the evening and then has the rain picks up later that night. It will be interesting (experiment) to see if this holds.

Showers Drizzle But Really not much Rainfall
Posted Monday 04/07/25 @ 5:39 PM — Despite all the clouds, fog, drizzle and showers/rain we had over the past several days, many areas did not receive much need accumulated rainfall. Here’s the 72 hour totals—

The system will slowly exit tonight and Tuesday should become windy, partly to mostly sunny and cold. Highs in the low to mid 40s.
Previously Posted Sun @ 7:43 PM — —The slowly moving cold front that passed through today will spawn another low pressure system tonight into Monday. Cold air will filter in behind this low.
It should be noted that while several models were originally forecasting some clearing Monday afternoon, while the ECMWF-AI model has consistently delayed that clearing until Monday evening. Monday should remain cloudy with showers, with diminishing coverage and intensity during the afternoon hours.

A well-advertised dip in the jet stream will occur over the Northeast this week following Colder than seasonal averages are expected.
Another storm is expected Friday into Friday night.
