2026-2027 Super El Nino
GaWx replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
Last 90 days of MJO still is the most left-sided on diagram for this time of year, April 22nd-July 20th, for any year on record (back to 1975…I just looked at all of them) and this new record should hold through the end of July at least: -
3.35" last night and 9.87" for July. Quite a turnaround from the previous few months.
-
That sorta reminds me of when I was a kid in the early 50’s and we used to play tag with, what we called, sun showers. I guess the convection strength was either very isolated or that the ASOS cover foliage in Central Park soaked up a lot of what was falling. I like your screen name. As always …..

Seems the GFS has a remnant EML in the vicinity for next week.

The next potential record breaking 600 DM ridge amplification will be much further west over the Rockies next week than the recent one over the Upper Midwest. That’s good news for our part of the CONUS. Most summers since 2010 with 100° heat in June and July for our area remained under 100° in August. Hope that recent pattern continues. Still not an El Niño-like pattern but an improvement for the Northeast. -
Machine learning did well in review, pointing out days well in advance. At least from what I read 7 to 10 days ago.

Looks like next week we go again Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0226 AM CDT Wed Jul 22 2026 Valid 251200Z - 301200Z ...DISCUSSION... ...Upper Midwest to Ohio Valley and Mid-Atlantic... An upper ridge centered over the High Plains will persist through the middle of next week. Meanwhile, upper troughing will be maintained over the eastern U.S. Periods of enhanced northwesterly flow aloft are expected across parts of the Upper Midwest/Great Lakes into parts of the Ohio Valley and Mid-Atlantic on the eastern periphery of the Plains upper ridge. Several shortwave impulses are forecast to develop southeast from Canada within this northwest flow regime. This could support daily severe thunderstorm chances from the Upper Midwest into the Ohio Valley, and possibly the Mid-Atlantic. However, the timing of these features is uncertain, and midlevel capping could limit the spatial extent of severe potential. It is likely that portions of the Upper Midwest into the Ohio Valley will need severe probabilities in later outlooks, particularly for Day 4-6/Sat-Mon, and possibly the mid-Atlantic by Day 7/Tue. However, confidence in where this risk will develop each day is too low for 15 percent delineation at this time. ..Leitman.. 07/22/2026

A 7.6” CoCoRAHS report from central WV! HoCo was a relative jackpot it looks like. 3.54” in downtown Columbia where I was getting soaked running to the movies and @canderson was at merriweather.

Finally the firehouse is off at the house for the moment. Ended up with around 2.73in of rain for the moment. Kinda glad I was on the southern end of it, as like Carver said, just 4mi to my W/NW, Radarscope is estimating Bean Station has had close to 6in of rain!!! -

Latest mean of CFS AAM prog: steady as she goes +1.5 to +2.0 into mid August indicative of strong El Niño (further out usually higher/too high due to + bias): -
This is what I could find on the fly. Have to get out the door. Will dig further for max monthly. Note: I don't track by calendar day. Obs. are from 8am - 8am.
-
My records go back to 2005.
-
Don't have any information on rainfall rates here. My period of record here is just about 9 years. Will have to go back and look to see what my wettest month was. Good question.

Carvers Gap replied to Carvers Gap's topic in Tennessee Valley
One thing which is nice about this in NE TN(not relief for everyone as has been shared), the drought is getting busted up here. We aren’t there yet, but much better off than during spring and winter. -
Do you happen to have any rainfall rate information from your station? I'm at 9.74" for the month making it the second wettest July for me, only topped by 2023 with 13.95". My average is 4.85". Interesting to note that I had .08" more in the Stratus than in the Davis which had to be due to splash out from the Davis in the 12.52" per hour rate for five minutes followed by a 11.76" rate for five minutes around 9:30pm last night.

As Jeff noted, that stalled frontal boundary has reared its ugly head this AM. Bean Station is seeing a lot of heavy rain. -

Total for yesterday 3.10". Two rounds. Early morning 1.72" in about 45 minutes. Second round with tornado warned storm early afternoon dropped 1.37" in about 15 minutes. Finished with .01" during the evening in a quick moving light shower. I'm good with rain for a while. Need some time for the ground to dry out. No need to water here anytime soon. Everything is as green as it could possibly be. @bluewave posted above the next big ridge looks to be centered more west over the western plains or Rockies. Watch for weak downstream trof over the east. Depending on placement that could signal another round of wet weather. A trof axis over the Ohio Valley or along the Appalachians would make for a wetter go around here.

The forester with whom we contracted in 2011 for forest inventory and modeling once commented, "All models are wrong, but some are useful." When Maine Public Lands contracted an inventory in 1999 (different contractor), the DOD had yet to remove the GPS scramble for non-military users. We had the foresters run their GPS units for 30 minutes on both the first and last of the 12-point cruise lines, with the goal of having the hundreds of scrambled hits averaging close to true location. We assumed the hits were truly random rather than biased.

40/70 Benchmark replied to Stormchaserchuck1's topic in Weather Forecasting and Discussion
I hate the heat, but the humidity is no prize, either....but I expect that in August...by far the most humid month, while July is hottest. It's the inverse of the winter, when January is coldest, but February is snowiest. at least here on the east coast. - Today

2% tor hatch for ME today ...New England... A shortwave trough/moderately strong mid-level jet streak will be favorably timed with diurnal destabilization during the afternoon, particularly for New Hampshire into Maine. As the cold front progresses eastward, scattered storms are expected to develop. Effective shear of 30-40 kt and strong upper-level winds will support the possibility of some supercells aside from organized multicells. Damaging winds, marginally severe hail, and perhaps a tornado are all possible this afternoon until around sunset.

6Z UKMET: weaker than 0Z’s 999 mb with 1005 mb when near GLV (hour 39). Most of rainfall S of GLV, where <1” falls, and Houston, where <0.5” falls. Peak of ~4” Matagorda Bay.
