It’s cloudy this morning and I rechecked the models, which now suggest that Saturday will be more cloudy than previously predicted. The latest HRRR even shows some light showers and sprinkles in the mid morning! And, the HRRR now includes a chance of showers today, early evening. There’s still a chance of some sunny bright spots around noontime, but mostly cloudy seems to capture it for now.
With the increased cloud cover, the high temperatures appear to be only around 65 for Saturday.
After the warm front passes this evening, things look better for Sunday.
The models still show mostly sunny skies and warm temps for Sunday. It will be breezy. Little if any chance of showers as well, although if the change for Saturday is any indication, I may have to update Sunday’s forecast as well.
The latest NAM data is in and it shows the precipitation taping off and ending between 12 and 2 PM in PHL and its immediate suburbs, with just lingering snow showers possible from wrap-around moisture. Winds will pick up.
Surface temperatures are predicted to drop by 2 PM, as well as temperatures in the upper atmosphere.
A changeover to a bit of snow or snow/sleet mix is possible before ending. BUT the thermal profiles still favor a precipitation mix of sleet/rain/snow and upper atmosphere temperatures remain a bit too warm for much snow formation before the precip exits.
Final snowfall/sleet totals won’t be much different than what you see out your window right now. What you see is what you’ll get.
