Updating Tonight's Rains

Radar is showing tonight's rains pushing northeast into the region, about on cue for timing as it steadily marches along.  After hitting 80 earlier today, tonight's rains in association with an advancing cold front will help set the stage for another round of cool but awesome weather for early next week.


Tonight's rains will continue to march east and northeast.  Having looked at the models over the last hour or so, there is some discrepancy in rainfall totals and distribution. The NAM's high res variant, see below, paints the heaviest rains across the north and west suburbs of Philadelphia, with lesser rains to the east of the city.  The HRRR (high resolution rapid refresh model) suggests a couple of swaths of heavier rain, one northwest and one along the Shore. In any of these heavier swaths of rain, an inch to perhaps inch and a half may fall. Other spots will see less rain -- probably a half inch to three quarters as outlined in our earlier post.


The good news? The rain that's moving through tonight will be largely out of the region by daybreak.
