Meteorologist. Into weather records. Soft spot for subtropical 🌀. 😻 and nature imagery, too.

If August ended today, it would be the shortest August on record.
Bertha briefly became a tropical storm. At the time, it had convection, albeit not well organized, near its low pressure center. It’s been so badly sheared the past 12+ hours that remnant low fits. Should its forward motion ever align with deep convection ahead of it, a center jump is possible.
I’m so happy that I’ve lived long enough to witness the 27th year of the importance of radiosondes debate and the 243rd year of debating Benjamin Franklin’s satirical essay on Daylight Saving Time. The pace of progress is breathtaking…something. 🤣

A cyclone with ~ 992 hPa pressure per offshore obs at noon their time. June low pressure records would be eclipsed at short POR sites if the cyclone came ashore at this intensity. For longer POR sites like Seattle and Portland, it would be close.

The Allison rainfall graphics were among the first that involved spreadsheet creation (Quattro Pro), one of the first done in near real time, and one of the few that involved manual plotting of datapoints back when the graphics were created in nMap/nAWIPS in 2002.

25 years ago #OTD: Tropical Storm Allison makes landfall in SE Texas, ~40 miles from Galveston. Over the next 5 days as it stalled and meandered, Allison produced extreme rainfall of up to 40" (1000mm) in the Houston metro, resulting in $5 billion in damages and at least 23 deaths in Texas alone.
Since we’re approaching the anniversary of the early July 2025 TX floods, this story map from New Braunfels TX gives it a comprehensive review. storymaps.arcgis.com/collections/...
July 2025 Central Texas Flooding
A summary of the widespread and catastrophic flooding occurred in Central Texas during the month of July 2025.

Something I plotted up showing how the Atlantic Hurricane Season shifts when taking the 3 mo ave RONI into account. El Niño conditions shift earlier in the tails. Neutral conditions shift later in the tails. La Niña conditions lead to even later shifts in the season, including the season peak.
Jangmi, beginning its extratropical transition, dropped Okinawa’s pressure to 980.4 hPa at 0900 UTC. This is shy of Kadena AFB’s record (POR since 1946) for June set 3 years ago, and marks the fourth time their sea level pressure dropped under 29” during June.
On this day in 1863, Cat. 2 Hurricane Amanda made landfall in N Florida, the only May hurricane known to hit the USA. There is a small window of no obs, which then it could have been a Cat. 3, but we conservatively declared it a Cat. 2. Paper available at journals.ametsoc.org/view/journal...
Surprised to see a graphic I recreated 27 years ago of an 1821 hurricane for the VA Hurricane History on television/YouTube
The red dots are where monthly sea level pressure records presently exist in the project. Note the 12 new dots in the Pacific. Thirteen new sites were added over the past month, including the Fiona landfall point in Canada.

From the morning walk. It’s been 10 days since the CABG surgery. 6-7 weeks of healing remain ahead.
Since it’s getting very warm/hot early, again, there’s no better time for USA Today’s heat safety tips. :p
Fallstreaks, including a hole punch cloud. I’d guess that the quasi-linear formation was caused by a contrail higher up that fell through the supercooled altocumulus layer. We are under the Dulles AP flight path.
