Pattern Dry July 2024

MHX put a flood watch on us...calling for a slow moving training line of storms right over the central coastal plains...
That is most likely happening. There will be plenty of storms from northeast NC southwest across the SC midlands into central GA that will only slowly move east with 2-4 inches of rain for many. Meanwhile it'll be mostly dry back to the west today. Hopefully we can get something back this way on Thursday, because after that we start to dry out and heat back up.
 
There goes any chance of rain for tomorrow too since GSP expects low clouds over the area again. If we do not get something Thursday, we will have to wait a long time for rain here. The NAM, GFS, and Euro are simply wrong. Right now, only the HRRR matters.
 
The GFS and Euro have not really backed off but are mostly wrong. Only the HRRR can be trusted right now.
I guess it just matters where you’re at because the 3kNAM has done very well in my area the last few days. I had another 1.2” overnight… the 4th straight with over an inch and I’m actually closing in on 9 for the month

We have not had more than .05 in any 1 event since July 7 here. Just trace amount mostly. BTW the heat is coming back this weekend along with drier weather. CAE is already talking about heat advisories and warnings in their area with near 100 degree highs there.
 
Thunderstorms in my area popping up along the seabreeze front. Thundering here. Could be a doozy.

I measured 1.75” over ~1.5 hours (~4:45-6:15 PM) (~5” last 4 days) though Doppler radar estimates are 2-4” over much of the area. That lead to a flash flood warning. The flooding was made worse due to heavy rains just 2-3 days ago. It has finally decreased to light rain. Check out this flooded street in another part of town (from news coverage):

Currently under another stationary storm.been pouring for 45 minutes at least
Yeah, the rich just get richer. I have my doubts about getting another drop of rain here until August. The models are wrong about the rain for later this week except for the HRRR. If it starts showing rain here, then we might just get a little bit, but I do not see it happening.

Now the HRRR says Wednesday will be dry too.

Barely more than a trace.
Storms are numerous but are just so localized. They really have to have a perfect track to get a good one. I’ve already got the shaft today. Thundering and rain in all directions.
 
PGV over 10" for month not counting the dumping we just got last hr....8" of that came in just 2 days. 5" on the 11th and 3.4" yesterday. Last month PGV recorded .45" for the month.

We have gone from significant drought to worrying about full rivers during a potentially active cane season...
 
Well after Thursday the pattern changes and it looks like I am going to be left with only .10 at best for the entire event unless we get a miracle. Our only chance here is with a ring of fire MCS or tropical system and anything like that is 10+ days away so the drought goes on. One thing the models will be right about is having the big heat come back in the long range.
 
The NWS products over the RadarScope app. Kinda looks like winter with being just on the line (mesoscale and flood, not winter storm! )
