QPF! Then I saw the dates. Lol. First thing I thought of when it pulled up was that looks like a tropical storm or hurricane track. Well it probably is but the dates are wrong!
Also for a minute I thought man thats a complete 180 in one update. Anyway, they will probably fix it shortly.

I'm going to put my money on the GFS... Prove me wrong upper level low!
Another Euro vs GFS battle lol go Euro!! At least this time
Yikes. If the models differ that much for rain I don't look forward to cane season models.
The GFS has caved towards the EURO.All of the global models are now showing the cutoff low slowly moving across the state.Still have to iron out qpf amounts though which are very hard to pinpoint with these setups.As a lot of it is driven by mesoscale features with this kind of setup.But a good trend overnight non the less.

Yep, the WPC's discussion this morning has a good summary on why there's a difference in general qpf amounts over the area.The potential is there for some to get excessive rainfall with this setup, but its nearly impossible to pinpoint this far out where those locations may be due to the mesocale driven nature of the setup.Cpv17 wrote: ↑Wed Apr 28, 2021 8:24 amThere’s still a lot of difference between the Euro and GFS in regards to qpf amounts.don wrote: ↑Wed Apr 28, 2021 7:48 am The GFS has caved towards the EURO.All of the global models are now showing the cutoff low slowly moving across the state.Still have to iron out qpf amounts though which are very hard to pinpoint with these setups.As a lot of it is driven by mesoscale features with this kind of setup.But a good trend overnight non the less.
Excessive Rainfall Discussion

...THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL FROM PARTS OF
SOUTHERN/EASTERN TEXAS INTO LOUISIANA...
The upper level low over northern Mexico/southern High Plains
should remain rather stationary over the region during the day 3
period/Friday while a surface boundary is draped along the Gulf
Coast and back into far south Texas. Anomalous moisture will be
advected east of the upper low pooling along the boundary to fuel
numerous showers and thunderstorms capable of producing locally
heavy rainfall. The latest 00z guidance shows some differences in
frontal placement, especially across far eastern/coastal Texas
with some potential the heaviest QPF stays offshore completely.
Just given the overall setup favorable for locally heavy to
excessive rains, a marginal risk was drawn across southern/eastern
Texas into northern and central Louisiana but the model
uncertainty precludes the inclusion of anything more than just a
marginal at this time.

"Points South of I-10" need to be the target this time.
i think we have had one good storm of 1+" since the freeze here in Cypress (A strong night time thunderstorm back in March). The forecast have continuously called out for areas north of I10 to get 1-2" of rain for a couple months now with each system and its continued to not provide here in Cypress.
That’s great news!! And south of I-10 too!don wrote: ↑Wed Apr 28, 2021 11:55 am 12z GFS has trended substantially wetter for southeast Texas,especially for the central and coastal counties.Looks to be two convergence zones setting up with the upper level low, one in central Texas, and another one across coastal Texas.Lets see if the trends continue...

lol I'm just trying to catch my breath. The Dewpoint rose to 71°F this afternoon and humidity is out of control. Just arrived home and put on a tank top and cranked up the ceiling fan in the home office. YUCK!
Guess I better get used to it until October.
Even DPs in the low 60s with a breeze the last few days was tolerable.
My 70% chance of “Heavy Rain” for tomorrow has been lowered to 50%.
Why am I not surprised...

18z HRRR doesn't look promising for tomorrow. Cap looks to come into play....again.
I had "Heavy Rain" forecasted this morning, now down to "Chance Storms" at 50%, as well jasons2k.
