Saturday's also looking wetter unfortunately at least on the euro

I'm taking the under based on recent events.   Looks like another cold front like today

Somewhat cooler weather will conclude the week. Overall, the first 10 days of May will likely see temperatures average cooler than normal normal overall.

Showers are possible Saturday night as a warm front moves across the region. Sunday will turn warmer with highs reaching the 70s.  Additional rain and somewhat cooler conditions will return for Monday. 

The ENSO Region 1+2 anomaly was +1.3°C and the Region 3.4 anomaly was +0.9°C for the week centered around April 29. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +1.47°C and the ENSO Region 3.4 anomaly has averaged +0.42°C. El Niño conditions will likely develop during late spring or early summer.

The SOI was -2.89 today. 

The preliminary Arctic Oscillation (AO) was -0.007 today.

Yeah I got only .06" from that round of light rain. Not enough to give the vegetable garden a decent watering. I see the models are showing another round of rain during the overnight hours, so hopefully we'll get more then. 

Looks like a downpour may clip us

This dry period to me is very interesting with its sudden onset and persistence, going on 21 months now... Station showing a 25" deficit during that period.

25" deficit in 21 months? That seems like alot.

Yeah it is... My normal precip is around 48.50" for the calendar year. In 2025 I had around 35" so there's 13 of that 25" deficit in twelve months.

Lol with the 0.04" today.

Yeah I had a very brief heavy downpour that dropped .05". Taking a look at radar now before I go to bed, I see a decent batch of rain is approaching. So maybe we can get a quarter to third of an inch out of this event afterall.

0.32” from the event. Not bad

Looks like a gradual warming later in May following this coming cooler period.

One thing to watch will be that we have a record +PMM now which is closer to the summer of 2015 El Niño than 2023 which didn’t have the strong +PMM.

So it’s possible we get a warmer summer than 2023. But we would want to see how the transition from late May into early June verifies in order to know for sure. 
 

Stronger +PMM in summer of 2015

Weaker PMM in 2023
