Safe to say June will end cooler than normal. Still not one day above normal for at least the upcoming week, even that most of it will be a wash.

The rest of June looks to be a write-off.

1.16" yesterday

Only reached 74 today. Between any rain, the dry hours were wasted. May very well not get out of the 60s tomorrow or Tuesday with even sunshine looking hard to come by the next few days. 18z GFS looks a bit worse for Tuesday:

The NAO and AO go negative while the PNA goes neutral to slightly positive around mid-month.

Feels like we're tracking a winter storm with the upcoming system

Looks like a short stretch of Fall weather is in store starting tomorrow.

That much rain? That's just the GooFuS talking.

Yesterday was the first day of measurable rainfall since May 20th. Only 0.12", though.

1st 90 of the year

12th consecutive day without measurable rainfall

It was the 8th driest May on record, though it was cooler than normal.

89'd today to kick off June. Possibly the highest we'll go for at least the 1st third of this month.

Tomorrow's going to suck. With the upper low around, some places may not get out of the 60s. Some will be stuck in the 50s. Some spots may brace for suicide weather. GFS: NAM:

Well, there is another cooldown later this week. GFS is hinting a cutoff low for Memorial Day weekend. 12z: 18z:

Below-normal temps look to be the rule for the upcoming week.

MJO looks a bit messy for the next couple of weeks. After the middle of May:

Coldest start to May, ever. 000 SXUS71 KILN 020540 RERDAY RECORD EVENT REPORT NATIONAL WEATHER SERVICE WILMINGTON OH 140 AM EST TUE MAY 02 2023 ...RECORD LOW MAXIMUM TEMPERATURE SET AT DAYTON OH... A RECORD LOW MAXIMUM TEMPERATURE OF 45 WAS SET AT DAYTON OH YESTERDAY, MAY 1ST. THIS BREAKS THE OLD DAILY RECORD OF 50 SET IN 1994. $$

CPC sticks a fork in May

Can be worse, right? I mean, the first half of May looks trainwrecky. Won't even be able to reach 50 for the first day or two of the month.
