Texas Summer 2023

[Texas Snowman]

Had a Flood Advisory this evening after 1-2 inches fell in and around Denison and the northern part of Grayson County. My backyard was swamped—I’ll take it!

Another 0.46" from a mid-day storm! If we can get some rain around this weekend I'll feel better going into this heat wave on the horizon.

Outflows doing work right over downtown Ft. Worth this evening

Now Irving getting in on the action

Irving definitely in on the action. Nice storm that cooled things off real quick. Good thunder and lightning.

Had a random downpour here earlier... I'm gonna miss this in a couple weeks. Possibly a run at triple digits next weekend... Yay so excited

Saturday has been highlighted as a severe weather risk since yesterday for central Texas up to Oklahoma and points east. Doesn’t look like a big tornado threat, but hail and winds appear to be on the menu

Update for SE Texas from Jeff Lindner:

A chance of strong to severe thunderstorms this afternoon over the region.

An upper level disturbance within the northwest flow on the outer edge of a building ridge of high pressure over northern Mexico will move across SE TX this afternoon and evening. Given surface heating and temperatures rising into the low 90’s by mid afternoon combined with lift from the approaching disturbance and decent moisture, clusters of showers and thunderstorms are likely to develop. Profiles support a strong/damaging wind threat with some of these storms depending on how organized they become. Cluster/line of storms will likely develop in the College Station to San Antonio corridor by mid afternoon and track SE toward the coast into the evening hours. Where this activity encounters the inland moving Seabreeze front some enhancement of storms will be possible. SPC has portions of the area in a 2 out of 5 risk level for damaging winds this afternoon and evening.

Ridge attempts to build into the area this weekend, but another disturbance in the NW flow looks to clip the area on Saturday and again may result or enhance some thunderstorms activity.

There after…high pressure become established into next week with gradually increasing high temperatures and heat index values…guidance progs heat index values near advisory criteria by next Thursday and Friday.

Tropics:
Nothing of interest in the Atlantic basin through the next 7 days. GFS continues to forecast a hurricane from the western Caribbean into the Gulf of Mexico the week of the 19th…it is the only model that is showing this (CMC and ECWMF do not show anything of significance in the western Caribbean during this period). I certainly question if the GFS has the correct upper air pattern in place since both the CMC and ECMWF have 30-40kts of wind shear over the western Caribbean Sea during this period. I normally would not mention such “long range” model speculation…but there are questions…simply put… I do not believe the GFS and this model has a tendency of developing western Caribbean tropical systems that never happen.

Severe Weather Outlook (This afternoon/Evening):

[Ntxw]

Looks like we are going to end up with a strong El Nino this year. It's been an odd evolution that has started slow but is increasing in intensity.

Spring rainfall has been mixed with some benefiting and some not. At some point though, the El Nino will be a huge driver. One of the coming seasons (Summer, Fall, Winter) will experience exceptional rainfall most likely. The PDO has been a block, but 2009 had a very wet Fall despite cold PDO-esque Nino.

[ElectricStorm]

Morning convection will probably ruin most of the severe threat for a good chunk of OK Saturday but down in TX could be more concerning. Could be an active pattern over the next week or so for June at least.

[South Texas Storms]

I'm tired of these big storms that keep causing damage and knocking out my power for hours in northwest Houston. Today's produced 60-70 mph winds and took out a big chunk of my tree in the front yard. Power has been out since 5:30pm.

Enhanced risk is up for Saturday including DFW

This event looks conditional for north Texas again, dependent on the track of an overnight mcs that should track across southern Oklahoma. If it manages to make it to the i20 corridor in the morning, I expect the risk area to shift significantly south (HRRR). However, if it dissipates or the area receives a glancing blow (NAM), the full risk would still be realized.

Looks like it is going to be awful hot for awhile. Ugh.

Side note: is this air quality alert expansion new? It used to be only used for big city areas like Houston or DFW.

Now most of eastern NE is under that for ozone, so not wildfires. Even parts of north OK with nobody living there.

It’s hard to take these ridiculous “alerts” serious when they are now issuing them when there is no legitimate air quality problem.

There is actually smoke particles across a lot of the US east of the Rockies. NE Oklahoma is within the area where there are elevated amounts. Now the criteria might be different for different areas, not sure on that one. It isn't just northeast Canada that has been on fire, so has western and central Canada. The east has been getting the most news coverage due to the big name cities but it covers a much larger area.

Milky low level smoke can be seen down the eastern Great Plains and throughout east of the MS.

HOT OFF THE GFS PRESS - CAT 5 IN THE GULF!!!!!!

I mean, it's only 360 hours out, what can go wrong?

[rwfromkansas]

Well oops. Nevermind. Thanks for the info. When I read the alert I thought they meant pollution.

Those Canadian fires have to be historic.

From Jeff Lindner at Harris County Flood Control:
Severe Thunderstorms will be possible Saturday afternoon and evening over portions of SE TX.

While high pressure is starting to build northward out of Mexico, a strong upper level disturbance will move around the northern and eastern sides of the building upper level high over portions of north and east Texas. A few days ago it appeared that the upper level ridge would have built into SE TX by this Saturday and guided any activity to our north and east, but the building high has been slower to evolve and this will allow the potential for this disturbance and it’s associated activity to move close or across SE TX on Saturday.

A large thunderstorm complex is likely across western Texas tonight associated with this disturbance and this activity will eventually weaken early Saturday morning across portions of west-central Texas. With surface heating and the approach of the upper level disturbance, scattered showers and thunderstorms will develop and move into and across the area, especially areas along and north of I-10. Current thinking is that areas across the northern and central portions of the area and into the eastern portions of the area will have the highest risk of storms and severe weather given the further extend away from higher heights over southern Texas.

Air mass will once again become very unstable Saturday afternoon and forecast profiles are favorable for strong damaging winds similar to Thursday afternoon where wind damage and gusts up to 70mph occurred over the area. SPC has much of the area north of I-10 in a level 2 out of 5 severe weather threat on Saturday afternoon. Storms will move from northwest to southeast across the region…again favoring areas mainly northeast of a line from College Station to Sealy to Freeport.

Next Week:

Ridge builds northward after Saturday and a stretch of hot weather is in store for the region with highs into the mid 90’s and then upper 90’s next week. Toward the end of next week, highs could approach 100 away from the coast. Heat index values starting Wednesday and beyond will likely reach into the 106-109 degree range which may require heat advisories for portions of the area. Rain chances will fall to near zero after Saturday with strong subsidence in place.

[bubba hotep]

Models have shifted the overnight MCS well east of DFW and really struggle to fire anything in the afternoon. I would roll the ENH back to Slight just based on lack of coverage.
