Storms starting to pop today already.

Looks like we might be in for a brief taste of fall.

Dying thunderstorm ending a very productive day around the house. It's nice to have patterns of our past!

Currently 62 with fog and occasional nwf showers in Wolf. Loving it!

Caught a few before and after pics of yesterday afternoon's storms.

Mesoscale Precipitation Discussion 0775

NWS Weather Prediction Center College Park MD

1230 PM EDT Tue Jul 22 2025

 

Areas affected...Carolina Piedmont into southern Appalachians

 

Concerning...Heavy rainfall...Flash flooding possible

 

Valid 221629Z - 222100Z

 

Summary...Isolated to scattered areas of flash flooding will be

possible across the Piedmont of NC/SC into the higher terrain of

the southern Appalachians through late afternoon. Rainfall rates

of 1-2 in/hr and localized 2+ in/hr rates will become likely but

much of that rainfall may fall over a sub-hourly timescale leading

to rapid runoff.

 

Discussion...GOES East visible and regional radar imagery at 16Z

showed scattered showers over far northeastern NC into western NC,

embedded within an anomalously moist environment in place over the

southeastern U.S. PW values on 12Z RAOBs from GSO and FFC ranged

from 2.1 to 2.2 inches, near or above the climatological max for

the middle of July per SPC data, and while PW values in the

mountains are naturally lower, similar PW percentile values are

likely into the terrain. Current cloud cover is likely limiting

MLCAPE over the western portions of the Carolinas with 16Z SPC

mesoanalysis data showing ~500 J/kg or less, but peak surface

heating is still a few hours away.

 

With continued surface heating, short term RAP forecasts show

MLCAPE values increasing into the 500-1500 J/kg range through 22Z.

The combination of sufficient instability and high moisture

(tall/skinny CAPEs) will allow for high short term rain rates via

efficient rainfall production. Deeper layer mean flow is oriented

from the NW at 5-10 kt, weaker to the south, which should allow

for relatively slow moving cells. 1-2 inches of rain in 30-60

minutes will be possible in the stronger cells that develop which

could lead to isolated to scattered areas of flash flooding.

I'm sad to learn of John Burns passing. God bless his family.
