HEAVY RAINS- Wed PM
Differences with the GFS vs NAM models, but all runs of the NAM today continued to show HEAVY rains through Thursday morning. (The GFS moves the precip out sooner than the NAM.) The NAM continues to pump out 3+ inches of rain for Wednesday through Thursday morning, with the heaviest rains after midnight tonight. I haven't seen numbers like this on the NAM FOUS data for several years. The axis of heavy rain has shifted to our west and NJ briefly at 9:30 PM, but expect it return to the PHL area later tonight.
The upper trough and very moist flow will continue to cause instability and thunderstorms through tonight and Thursday morning.
Instability from the upper trough will possibly cause showers this Saturday. Things clear our for Sunday.
Sat 7/26: Tentative forecast- Partly cloudy with showers.
Sun 7/27: Tentative forecast -Mostly sunny.

HEAVY RAINS- Wed AM
The latest NAM pumps out over 4 inches of rain for Wednesday night! I haven't seen numbers like this on the NAM FOUS data for years. We gotta watch this!
An upper trough will cause unstability along with a surface low over our area Wednesday into Thursday. Flooding conditions may develop Wednesday night in some areas.
Instability from the upper trough will possibly cause showers this Saturday. Things clear our for Sunday.
Sat 7/26: Tentative forecast- Partly cloudy with showers.
Sun 7/27: Tentative forecast -Mostly sunny.
