First time since 1988 here around HVN that the strongest May wind gusts occurred so late in the month. So an unusually strong late May storm system. Very impressive omega block for this time of year.

40.2 in Muttontown & 43.0 in Syosset this morning. 

[SACRUS]

Down to 40 here now 63 / 42.  A gorgeous day ahead mid 70s to low 80s as the ULL out to see and overall yesterday wasnt half bad.  Near normal / dry week balanced by a cooler Mon/Tue and warm to potentially sneaky heat Thu - Fri.  Overall normal to above once to the 4th and beyond.  Core of the highest departures remain to the north and west with flow flattening a bit - more ridging / sustained warmth second week of June.

1889 - The Johnstown disaster occurred, the worst flood tragedy in U.S. history. Heavy rains collapsed the South Fork Dam sending a thirty foot wall of water rushing down the already flooded Conemaugh Valley.

That occurred before 1 am EDT, so it was counted as yesterday's low. Records are based on standard time.

Gotta love statistics…. Mark Twain having a laugh. 

Gorgeous out; enjoy the day all!

Going to be interesting to see if Upton's forecast of Mostly Sunny verifies as we head into the afternoon hours

Sampling of lowest mins across NJ this morning.

Low of 43 here.  So great to still be sleeping with the windows open.

Back to a drier pattern again.  Not much rain in sight next 7 to maybe 10 days.  Thankfully no big heat either.
