The latest GFS and NAM models show a low pressure system moving up the coast Wednesday with heavy rain mixing with and changing to snow before ending Wednesday evening. Accumulations look to be light in PHL, but bad timing for any holiday travel. Stay tuned.

Heavy rain expected tomorrow (Monday) with the cold front moving through Monday evening.

This front will be a polar front and high temperatures will be only in the low 30s Tuesday and Wednesday.

Once we get past this week, a more moderate air mass will be with us next week and over Thanksgiving.

The model forecasts for the sharp upper trough expected to develop late Friday into Saturday continue to change.  Yesterday, the trough was expected to spawn two surface lows, both fairly far off the coast.  The latest GFS shows a single deep coastal low develops closer to our area and brings more rain into our area on Saturday.  The surface low will deepen and bring very windy conditions to our area Saturday.

Right now, temperatures are not going to be low enough have snow or snow showers as had been thought earlier in the week.  But the trend is for windier conditions and more rain on Saturday.
