Bustolla on the showers today

Most spots will see the start of Chester County’s  2^nd “heat wave” of the summer season. Today through Wednesday should see highs topping out in the low 90’s each day. Today could be the exception across the higher ridge locales with highs a degree or two short of 90. A strong cold front will start to cross the area by later Wednesday night with shower and t-storm chances increasing and signal a nice change to below normal temperatures for next weekend. Below normal temperatures look likely for at least the first week of August.

That humidity was just brutal yesterday. Looks like KABE got to a peak dew point of 77 which is fairly rare for this area. Good thing it wasn’t terribly hot or else it would have been completely miserable out there. Really looking forward to the arrival of the cold front on Thursday night…hopefully we get a good day or two of storms before that.

As I mentioned yesterday some of our higher spots across the County had the potential not to reach 90 degrees on Monday and indeed 7 of the stations failed to reach there. So for those spots they will not "enjoy" their 2nd "heat wave" of the summer. For everybody else today will be day 2 and tomorrow day 3 but the final day of the "heat wave". We could see some heavy rain by later Thursday with a strong cold frontal passage. This will usher in well below normal temperatures for the weekend with an almost autumnal feeling as highs are in the 70's and nights in the 50's.

Honestly I love this weather 

I can tell you didn’t write the forecast discussion for Mt. Holly this evening, lol:

"Wednesday will be a repeat of today with more hot temps & obnoxious humidity for the area."

“Obnoxious” omg..

Today should be our last 90-degree day for at least the next 10 or so days. We will see rain chances ramping up tomorrow afternoon into the evening with a cold front. We could see at least an inch of rain in many spots across the area with showers lasting until Friday. On Friday night we see some autumn like weather arrive for the weekend. Highs mostly in the 70's with lows in the 50's. Below normal temperatures look to continue through much of next week.

If you believe the 12z NAM and a few other hi-res models, some places may not get out of the 60s on Friday. It just makes today’s heat and humidity feel so much worse knowing a long stretch of comfortable weather is right around the corner.

Someone in the NYC forum said the NAM is amping up precipitation for Friday too

Tomorrow night but yes. The mesos generally agree that there will be a 3-6" bullseye somewhere between Philly and NYC with everyone else getting 1-2".
