It will be interesting to see if Philly can record their first 3 consecutive years under 40.00” since the early 1990s .

Long range precipitation forecasting is very uncertain.

The hope is that the STJ can come far enough north with the developing super El Niño to increase the rainfall enough in coming months to get over 40.00” by the end of December. 

Many spots have been running drier than average starting with the big dip in rainfall in September into October 2024.

I feel that it's time that we have a real serious discussion about next week's heat potential. Some places in and around the I-95 corridor could approach near record monthly high temperatures next Tuesday,  if this air mass lives up to it's full billing!

Yeah, it might be hot.  I think we will survive.  Its been 90 already this year and we pulled through.

We’ve had mid to upper 90s heat waves in May before, that’s not unprecedented. It also might be for just half this subforum since a lot of it looks southerly wind driven. Maybe we get another crazy Ambrose Jet day or two in this and the immediate south shore can’t get above 70.

Given the dry soil conditions-the hot spots could maybe do upper 90's

I'm thinking my location will hit 97 or 98 on Tuesday.
