Leaving work for the day and seeing a rainbow 🌈 then sunshine 🌞 following a late Thursday afternoon rain shower. 🌧

Here we go… #NJwx #mastodonwx

A severe thunderstorm watch has been issued for parts of New Jersey and Pennsylvania until 9 PM EDT

Sure, we've had 1st Special Weather Statement (intense snow squall today).

But what about 2nd Special Weather Statement? (24h snowstorm Wed-Thu)

#ottawa #onstorm #mastodonwx

71° - outperforming the forecast and still some daylight hours left #Weather #MastodonWX #warm #southeast

I've posted 360 times in the last 7 days - not including this post. Lots of bad weather out there this January. 😢

If that's too much, one thought for @ivory users is that you could create a list for "Weather" or "Cool bots" and then filter me from your home timeline.

Maybe our fear of online companies "knowing too much about us" is overblown. Exhibit A: email from #Amazon this morning trying to sell me a #snowblower.

Forecast high temperature here today - 75f

Wore shorts today to insult the winter weather spirits, who seem to be lost.

Puny god!

Seems it's going to be warmer than normal for a while in the east. #mastodonwx

A great article with photos and weather charts about the Great Blizzard of 1978...the current record-holder for all-time low pressure at #Ottawa...a record we were not particularly close to busting last week.

One interesting difference is that in 1978, there were 2 western "bully highs" combining...starting somewhat further east...yet they produced a storm that tracked somewhat farther west.

Ottawa airport recorded a pressure of 96.24 KPa at 1PM on Dec 23rd. That seems to be breaking the all-time record of 96.36 set on Jan 26, 1978.

But when I check Ottawa's actual records on that day, it shows 95.03 on that date, since the NOAA chart of all-time pressure records is calibrated to sea level.

96.36 @ 80m elevation and 2 deg C would be 97.2

96.36 @ 0m and 2C would be 95.03

So Ottawa was still some distance from breaking the all-time low pressure record.

#onstorm #mastodonwx

The barometric pressure in Ottawa has risen slightly, the wind has changed to the SW.

Gird your loins for winter's angry return!

Curious to see if there will be another small decline in pressure as the merging low centers wobble around each other over NE Ontario, as forecast by the GFS and ECMWF.

#onstorm #mastodonwx

Now the ECMWF is getting in on the breaking of all-time low pressure records for E. Ontario & West Quebec...

Most models had drifted away from that in the past few runs, but the ECMWF is the gold standard at the moment.

The forecast wind gusts over most of southern Quebec look catastrophic. 110km/h is not normal there.

And PEC and the 401 might be seeing 120km/h gusts.

Down in #Mississippi where the snow falls down from the sky...

Where they give it up and they give it up and they never ask why....

Snow and cold modelled for parts of Mississippi

Via the NWS office in Cheyenne, Wyoming…the arctic front has moved through Cheyenne, resulting in a 40° F drop (43° ➡️ 3°) in temperature in JUST 30 MINUTES! Yikes!

Wow! The NWS office in Birmingham, Alabama...ALABAMA!...just issued its first WIND CHILL WARNING ever (became a thing in 2006-07)...expecting wind chills between 0° and -12° #ALwx #mastodonwx

Literally, an inland hurricane

Dec 23 to 24, backside Dec 25- ? with pretty massive squalls.

If any border wall should be built, it should on the USA-Canada border so they can keep all their stupid cold air to themselves.

Looks like a dry morning across most of #NewMexico. A few #CoCoRaHS observers reported traces in their rain gauges. #NMWX #mastodonwx
