Historical:

 

1890 - Saint Louis, MO, received 20 inches of snow in 24 hours. It was the worst snowstorm of record for the St Louis. (David Ludlum)


1942: 107 inches of rain fell during the month at Puu Kukui at Maui, Hawaii to set the U.S. record for rainfall in one month. The same place also holds the annual rainfall record for the United States with 578 inches in 1950.

1954 - The temperature at Rio Grande City, TX, hit 108 degrees, which for thirty years was a U.S. record for the month of March. (The Weather Channel)

1962 - A tornado struck the town of Milton, FL, killing 17 persons and injuring 100 others. It was the worst tornado disaster in Florida history. (David Ludlum)

1973 - A devastating tornado took a nearly continuous 75 mile path through north central Georgia causing more than 113 million dollars damage, the highest total of record for a natural disaster in the state. (The Weather Channel)

1987 - March went out like a lion in the northeastern U.S. A slow moving storm produced heavy snow in the Lower Great Lakes Region, and heavy rain in New England. Heavy rain and melting snow caused catastrophic flooding along rivers and streams in Maine and New Hampshire. Strong southerly winds ahead of the storm gusted to 62 mph at New York City, and reached 87 mph at Milton MA. (The National Weather Summary) (Storm Data)

1988 - March went out like a lion in eastern Colorado. A winter-like storm produced 42 inches of snow at Lake Isabel, including 20 inches in six hours. Fort Collins reported 15 inches of snow in 24 hours. Winds gusted to 80 mph at Centerville UT. Albuquerque NM received 14 inches of snow. (The National Weather Summary) (Storm Data)

1989 - Afternoon thunderstorms produced severe weather from North Carolina to Pennsylvania. Thunderstorm winds gusted to 76 mph at Cape Henry VA. While squalls blanketed northwest Pennsylvania with up to 9 inches of snow, thunderstorms in eastern Pennsylvania produced golf ball size hail at Avondale. (Storm Data) (The National Weather Summary)

1990 - The month of March went out just as it came in, like a lamb. Marquette MI, which started the month with a record high of 52 degrees, equalled their record for the date with a reading of 62 degrees. (The National Weather Summary)

2010 - Jacksonville, Florida's, record streak of days with high temperatures below 80 degrees comes to an end at 105 days. It was also Jacksonville's first 80 degree reading of the year. The previous latest first 80 degree day was on March 14, 1978.

The week ahead:

With the snow season likely completed in much of the region, this will be the last such post until next winter.

Final outcome: The period was warmer than had been shown on the guidance. The high temperatures well far higher than the values suggested on the guidance.

Slight risk extended east again

From the SPC update:

 ...Mid-Atlantic to the Northeast...
   Instability is expected to weaken with northward extent ahead of the
   cold front across the Mid-Atlantic and Northeast. Still, scattered
   thunderstorms should develop this afternoon and spread
   east-northeastward towards the coast through the evening. With
   enhanced low/mid-level flow present in association with the lead
   shortwave trough, some of this convection may pose a threat for
   damaging winds and perhaps a tornado or two, before it eventually
   moves offshore.

Nams are well west with the heaviest rains. Only models really showing this

[SACRUS]

Up to 70 in this yoyo pattern

Well west would be consistent with much of the pattern over the last 8 months.

The HRRR sort of is too.  The one thing most models agree on is the TSTMs 21-23Z over NRN-CNTRL NJ.  The Euro idea though of steady rain by 2330-00Z from NYC and east is probably more likely than the HRRR/NAM holding that area back til 02-03Z

The storm threat drops East of the Hudson however I like today's threat for Northern/Central NJ extending into the LHV, especially if we can get some clearing.

I think 21-23Z is the chance for any "real" activity.  Its possible the 00-03Z period could have alot of elevated activity, even as far east as Queens/WRN LI but I always am reluctant at this time of year to even count on that due to the water temps

The dew point is above the dreaded, for some of us, 60 degree line.

Stuck in the junk. Sun is trying to break through, though on in Lynbrook.
