Ed, snow and hurricane fan

Been consistent for days, heavy rain N & W of Houston, NWS HGX has issued a Flood Watch for the counties North and West of Houston, including Montgomery County. HRRR is especially enthusiastic. What has also been consistent, first on the globals, and now the mesos, a very sharp cutoff between heavy rain and much lighter rain. Edit to Add: My son flying from DFW this evening and American has been delaying his flight. WPC has a meso rainfall discussion for pretty much the entire stretch of I-20.

Updated SWODY 2 has two enhanced area, one in N Kansas and Nebraska, a second in W. Texas and Oklahoma, the TX/OK one being conditional on storms developing. 12Z HRRR thinks the dryline in Texas will go, to a lesser extent the GFS as well. 3 km NAM still shows a stout cap. SWODY 3 mentions a possible increase from SLIGHT for the ArkLaTex area. Not seeing much on 12Z 12km NAM or GFS to support an upgrade, but it is at the limit of the NAMs.

It looked a lot better a couple of days ago on the models. It had looked like storms would initiate early evening at maximum instability. It is starting later, and low level instability is low. GFS showing elevated storms, NAM doesn't show anything. SPS forecast sounding below. It might work if a special 18Z sounding but it isn't. 30% at 5 days, that usually means a big outbreak. Still 3 day ENH, and SPC looks at stuff amateurs like me can't see or don't have time to see.

It may be too late already. https://tos.org/oceanography/article/is-the-atlantic-overturning-circulation-approaching-a-tipping-point

Baseball hail just N/NW of Austin. I assume this will grow upscale, may stay as far S as I-10 and wake me up an hour before my alarm is set for.

3 inch hail in PDS Severe Thunderstorm Warning just N/NW of Austin. Just heard it on Ryan Hall. Not on NWS yes. 3 inch hail. Edit- I feel cheated, the words 'particularly dangerous' nor the letters PDS are part of the text.

Looks even better in a loop, but I don't have the attachment size left.

>80 dBZ with warned hailer E-ern Dallas County.

I haven't compared as you have, but Dr. Klotzbach mentioned in his 2024 prediction recent April forecasts have improved. Hadley Cell talk makes me wonder, they don't (usually) have time to become extreme, but pieces of mid-level disturbances that break off and come back W as inverted troughs sometimes spin up. Locally (NW Gulf), Edouard and Humberto come to mine, Lee was badly sheared, making landfall in Louisiana with no rain of the W side in 2011, but it blew down the powerlines that started the Bastrop fire E of Austin. Rural country, but 1700 structures destroyed in 7 weeks, two dead. Even if the MDR is a bit suppressed, US threat is not zero. Alicia, last major to landfall inside NWS HGX CWA over 40 years ago, was of non-tropical origin. First day of fire, I didn't think trees that green would burn. But rainless tropical storm and no rain all summer. Below video from day fire started, between Bastrop and La Grange.

DFW to SPS in an Enhanced for tomorrow, 30% hail and hatched. Late ahead of storms in the 287 area between the two cities, lapse rates in the hail layer between near 7 to near 8C/km, near 60 knot 0-6km shear per 12Z hi-res NAM. CINH is increasing, but enough 1 km helicity for a possible tornado.

94% totality down here. Can't wait for my mid day clouds become like 5 am clouds, before going back to early afternoon overcast.

2 inch PW is more common in August. Severe signal is muted Monday in East Texas on NAM, long skinny CAPE from a near saturated sounding although impressive hodo, closer to I-35, nice EML and better CAPE, but hodos not good. 6Z Euro has widespread 4 inch 48 hour rainfall with near 7 inch bullseyes in Piney Woods. GFS not as dramatic and a smidge N, but a signal for excessive rainfall in N and E Texas. WPC has N and E Texas in a SLIGHT RISK area Monday and Tuesday for excessive rain. WPC 5 day QPF over 5 inches extreme E Texas to the ArkLaMiss.

Consistent signal (0Z, 6Z) NAM for an MCS to form over Central Texas and move E. NAM and GFS don't support, Canadian does.

At least San Antonio and Austin are in a Day 3 hatched sig-severe, language suggests for large to very large hail.

The same thing that made for a boring cold season might make this the year a major hurricane makes it to New England. The 26C isotherm in September usually gets as far N as the latitude of Delaware, it still won't reach the coast, but it'll be closer and the waters S of Long Island/SNE won't be so cold a storm falls apart quickly. OK, those of you on the coast might prefer snow to having a North Carolina-esque hurricane season (and mid-Atlantic type snowfall), but the trend in ocean temps doesn't seem in your favor. The AMO threw a head fake it might be headed back neutral about 2019/2020, but The two summers we rented a house in Harwichport, I was so early teen nerd excited about hurricanes. I was just born 50 years too soon. I remember an April snowstorm on Long Island 1980 or so, when BOS was rain. @MJO812might know what year that was. But April snow is special.
