0.46" since 8am and 0.85" total so far. Moderate rain continues.

Already seems like an overperformer, 0.39" so far, with much more incoming on radar. NWS Sterling updated forecast at 430am was for half to 3/4 inch of rain for my location.

A recent ASCAT-B overpass shows a large area of hurricane- force winds southwest and south of the center of Dorian, with many vectors of 80 kt or more. This area of wind is likely due to baroclinic effects during the ongoing extratropical transition. The initial intensity is being increased to 85 kt and the 12-h intensity to 75 kt, after which the forecast intensities are the same as in the previous advisory. Some changes were also made to the initial and 12-h wind radii based on the scatterometer data. There is no change to the forecast track from the previous advisory.

Our region is upgraded to Slight Risk

PD1 was and is, to this day my all time favorite storm as well, living here in southern MD. Schools closed for a week, snow packed engine blocks, drifts up to the 2nd story and total whiteout conditions for hours.

SPC day 2 did upgrade to Slight risk for a very small corridor. HGR down to DCA east/northeastward to central NJ

DCA hit 99/72 at 135, 145 and 150pm

Yeah, those storms are falling apart pretty rapidly now.

The storms entering Pennsylvania above Pittsburgh, could interrupt the extreme heat this afternoon.

F5 weather/Eurowx.com had the strong hurricane for UKMET as well, way lower than 980 at landfall western LA. Certainly a cat 2, with the wind gust estimates at 125 mph. Not buying into that. If this system/Barry makes landfall in central/western LA the rainfall will be the largest issue. Mississippi River is not capable of handling a large rain event.

Wow, pretty darned good when you are fringed by the storms and still get 3.07" for the day and the vast majority was in 90 minutes. The Cameron Run roaring beside and under the Beltway was extremely impressive, I found out that it had dropped almost 2 feet from it's peak, when I passed through.

That blob of heavy rain following behind and moving south out of Howard and eastern Montgomery isn't going to help DC/Arlington/Alexandria and PG County at all.
