August finished with a monthly mean temperature of a preliminary 75.8° (0.4° below normal). That was 0.6° above the prior 1981-2010 baseline.

It will turn somewhat warmer tomorrow with the temperature topping out in the middle 80s. Showers and thundershowers are possible late tomorrow and Wednesday. 

Excessive heat with highs in the middle and upper 90s will be just south of the region in such cities as Baltimore and Washington Tuesday through Thursday.

The ENSO Region 1+2 anomaly was +4.2°C and the Region 3.4 anomaly was +2.6°C for the week centered around August 26. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +3.93°C and the ENSO Region 3.4 anomaly has averaged +2.50°C. The ongoing strong El Niño, which has reached super El Niño threshold, will continue to strengthen through the summer.

The SOI was -0.79 yesterday. 

The preliminary Arctic Oscillation (AO) was +0.654 today. 

 

El Niño summer pattern finally kicking in

So only the park was below normal. Makes sense that we focus on it so much.
