Thursday afternoon through Friday morning — Look for a wintry mess. Snow, sleet, freezing rain. All inbound to Southern New England. Similar to Tuesday but a bit more south. Careful on walkways and roads between 5 pm and 9 am.

Tornado season has arrived. Last March saw 300 preliminary tornadoes — a new record for the month, reported over 20 states.

March brings moisture from the Gulf, clashing with chunks of winter's lingering chill.

The U.S. sees 95 March tornadoes on average. @bostonglobe.com

Hurricane #Melissa retired by the WMO. The new name? Molly. Melissa was a Category 5 monster that tied for the strongest landfalling hurricane ever in the Atlantic.

190 max wind speeds, 892 lowest pressure, 252 mph wind gust.

Ended up with more than a coating to 1" last night. Cold air remained trapped at the surface & didn't really escape before the warm front arrived. This meant large wet snowflakes from plenty of moisture present & temperatures right at freezing. Rt.-2 saw totals 3-5"

Meteorological Winter Recap: snowier than avg. for 5 of 6 #NewEngland states, sorry #Maine.

Providence saw the snowiest winter on record. Boston finished 9th. Colder winter than normal everywhere, 3-4° below avg. Little rain everywhere.

What a divided winter across the country! 12-1 to 2-28.

Rankings: Out west, the warmest winter on record for many, but once you cross the Mississippi River, cold, cold, and more cold.

Classic western ridge & eastern trough setup this winter.

Sure, a system will bring a coating of snow/wintry mix to # Boston this evening.

BUT warmer air on the horizon. Jet stream turns zonal (flat) and warm air moves in. 50s by the weekend, 60s next week across Southern #NewEngland?

Wintry mess this afternoon & evening. A coating of snow is possible before being washed away in Greater Boston. Some icy spots too late Tue. & early Wed. Accumulating snow up north.

Took a look at this winter's snow totals vs. 2014-2015's "Snowmageddon".

Boston is pacing the highest snow totals since that winter, but is still 40" short of that record-setting season!

Providence is on pace to beat it!

Happy meteorological spring! Yes, March does bring snow, BUT here are the 12/1-2/28 snow totals.
- #Boston: 60.9" (avg. 32.8")
- Milton: 78.6" (avg. 44.1")
- Providence: 68.5" (avg. 26.7")
- Worcester: 76.8" (avg. 45")

Nearly double for some spots!

Monday might be the last freezing day of winter for #Boston and most of Southern New England. Warming trend on the horizon with the first half of March likely much warmer than average across #NewEngland

Quick peek forward. Light snow coming Sunday morning, most see a coating, but a few spots can pick up an inch or two.

67.8" of snow this winter for #Providence, 2nd highest ever total before Feb. 25 in a season. Only 1995-1996 had 77" before Feb. 25 AND had another 28" fall after that date. Wow.

Frontogensis draped across the jackpot zone. This is where the atmosphere squeezed so hard to drop 4"/hr snowfall rates.

3' of snow in parts of RI & SE Mass. How?

A late shift east + frontogenesis + instability = long-standing snow band of 6+ hours.

The science behind how we got to historic jackpot snow totals 6" more than any forecast.

A bit more snow is entering New England on Wednesday morning, but held north and west of the jackpot zone of the Blizzard of '26. This clipper will be in and out in a hurry, but a wet commute on Wednesday.

Top 10 snow totals across MA & RI from #Blizzardof26.
Multiple new storm snowfall records were set for some of the top-10 locations. Keep in mind, some spots don't have stations & are spotter submissions, but probably are new records.

Wow. #tfgreen hit 37.9" - just a hair below the all-time snow storm record in Rhode Island. .1" below the 38" set in Woonsocket from Blizzard of '78.

Blizzard of '26, a clone of Blizzard of '78? It's close.

'78 top snow totals: 36" in MA, 38" in RI
'26 top snow totals: 31" in MA, 36.2" in RI
Lowest pressure: '26 = 968 mb, '79 955.5

'78 wins, but barely. Both near exact storm track. Wow.

And now #Massachusetts joins the club. A new state record for 24-hour snow total as Somerset passes 31".
The previous record was 29" in 24 hours in Natick (4/1/1997)

Coming up next. Likely new record for 24-hr snow total in Massachusetts.

Somerset sits at 28.7". The standing record is 29" in Natick, set back on 4/1/97.

Ok, so this bomb cyclone sits at 968 mb. Blizzard of '78 dropped to 955.5 mb, and Storm of the Century 1993 dropped to 960 mb. This will be an all-timer.

Well that didn't last long. A new new state record at T.F. Green airport - 32.8" and climbing!!

This jumps over the previous 24-hr snow total record (Woonsocket - 30") set back during the Blizzard of '78

New state 24-hr snow total record for #RhodeIsland. Warwick reached 31.5", passing Woonsocket's 30" total from the Blizzard of '78! Wild. One or two local totals can reach 3 feet in Rhode Island/Southeast Mass. Wow.
