It’s ***early*** and ***SSS*** obviously but have you noticed anything different with his swing mechanics so far? Any reason to at least be somewhat optimistic he can turn it around?

@nws.noaa.gov Director Ken Graham presented on NOAA’s modeling grand challenge at #AMS2026 this morning. He announced that the NWS is moving to MPAS as its modeling dynamical core, with his #1 moonshot goal being a global, fully coupled 3-km Earth prediction system using MPAS.

It sure *feels* like this is going to drag out for a while. Crazy to think that Framber met with teams at the GM meetings almost 2 months ago!

Now that Imai has signed, does the rest of the high-end starter market start ramping up? Personally not sure what to make of it, considering Imai’s contract is not at all what I was expecting (given all of the opt-outs). I initially figured he would help set the market, but maybe not so much.

WPC has initiated Key Messages for an impending coastal storm that will look to generate strong wind gusts, heavy rainfall, and significant coastal impacts that include coastal flooding, rip currents, and beach erosion along portions of the East Coast over the upcoming weekend.

Highly unusual situation approaching western Colorado with the moisture from Hurricane Priscilla. Grand Junction has never had precipitable water over an inch (25mm) so late in the year, but looks like it will be near that level on both Fri & Sat. Six standard deviations above average! #cowx 1/2

Think it’s been especially humid in the DMV lately? You’d be right. Avg dew point (computed by averaging daily max/min dew point) at the three major climate sites (BWI/DCA/IAD) for July 2025 thru today all top 2 on record, and BWI is #1. Yuck.

WPC issued as many as six MPDs for the deadly flash flooding in the TX Hill Country starting yesterday evening and lasting through much of today. The first MPD generally set the stage for what was to come, while the next three shown were as the event unfolded.

NOAA Weather Prediction Center Excessive Rainfall Outlooks all valid for 2-3 April 2025. The outlooks were very consistent in their location and the observed flooding occurred essentially right in the locations where the outlooks showed the highest probabilities.

We often (rightly) see maps like these showing how good SPC convective outlooks are; let's also give some kudos to WPC for some outstanding excessive rainfall outlooks for this event. Especially impressive are the day 5 outlooks, giving advance notice of prolonged excessive rainfall and flood risk.
