I edited my post above and added the images

12z Euro apparently left the oven on for Thursday to Saturday looking at 2mT Thursday 2pm 2mT Friday 2pm 2mT Saturday 2pm 2mT

We need a write up on what went wrong

@Eskimo Joe already calling for extreme heat risk by LWX in this afternoon AFD KEY MESSAGE 2...Significant heat risk next week heading into the Independence Day holiday. Increased confidence for a prolonged period of extreme heat and humidity starting Tuesday, June 30th and lasting through the Independence Day July 4th holiday weekend. Synoptically, subtropical high pressure and a building upper-level ridge will allow temperatures and humidity values to climb toward record levels over a multi-day period mid to late next week. Temperatures start to climb Tuesday as the upper-level ridge expands eastward from the Ohio River Valley. Look for highs in the 90s with heat indices running between 95-100 degrees. Wednesday through Sunday will be the peak of the dangerous heat with highs for most in the upper 90s and lower 100s. Heat indices each afternoon will run between 102-108 degrees with a few readings around 110 along the immediate I-95 metro corridor, western shore of the bay/southern MD, and down across the VA Piedmont region. Minimal relief is expected across the mountains with highs in the mid 80s and low 90s and heat indices in the mid to upper 90s as the heat peaks mid to late week. No relief at night either with widespread lows in the upper 60s to mid 70s (upper 70s-80 urban areas) Wednesday through Saturday. With that said, looking at major to extreme heat risk across the region during this period. Heat headlines will likely be needed and evaluated as the event gets closer. More at weather.gov/lwx/heat. Model guidance (00z, 06z, and 12z) has come into better alignment in regards to temperatures next week with only a few degrees of spread. On the other side of the spectrum, some uncertainty remains in regards to storm chances given the placement of boundaries and any waves of low pressure that may clear away the heat. The ridge looks to sit just west of the region if not overhead Tuesday before shunting eastward late week into the weekend. This would keep storm chances suppressed across most of the region outside of the mountains Tuesday through Thursday given the lack of any real forcing mechanisms outside the terrain or perhaps bay/river breezes. This changes Thursday through the weekend where storm chances may be amplified given a few pieces of energy pivoting over the top of the upper-level ridge in west to northwest flow. With excessive heat and humidity there will be plenty of instability to work with. You combine this with any potential ripples of low pressure moving around the ridge or a bay/river breeze to get convective development. This is illustrated by CSU/CIPS/NSSL (15-40 percent probabilities) outlooks along with Google WxNext AI model which suggest the risk for severe weather during the Thursday July 2nd to Saturday July 4th timeframe. Something we`ll continue to monitor in subsequent forecast shifts given all the ongoing outdoor activities across the region. Historically, near record summer heat often ends with widespread strong thunderstorm activity, and latest guidance starts to break down the heat next weekend (July 4) into early next week.

Happy Birthday!

LWX afternoon AFD already mentioning low 100s @Eskimo Joe Wednesday through Friday will be the peak of the heat with highs for most in the upper 90s and lower 100s. Heat indices each afternoon with run between 102-107 degrees with a few readings around 110 along the immediate I-95 metro corridor and down across the VA Piedmont region. Minimal relief is expected across the mountains with highs in the mid 80s to low 90s and heat indices in the mid to upper 90s as the heat peaks mid to late week. No relief at night either with widespread lows in the upper 60s to mid 70s (upper 70s-80 urban areas) Wednesday through Saturday. More at weather.gov/lwx/heat. Even with that said, there still remains some spread in temperature data mid to late next week. Some of this is due top the placement and positioning of the ridge along with any t-storm chances that may develop late next week. Right now, any convection looks to be tied to the mountains Wednesday and Thursday due in part to the terrain influence. With excessive heat and humidity there will be plenty of instability to work with. You combine this with any potential ripples of low pressure moving around the ridge or a bay/river breeze to get convective development. This is illustrated by both the CSU/CIPS outlooks along with Google WxNext AI model which suggest the risk for severe weather during the Friday July 3rd and Saturday July 4 timeframe. Something we`ll continue to monitor in subsequent forecast shifts. Historically, near record summer heat often ends with widespread strong thunderstorm activity, and latest guidance starts to break down the heat next weekend (July 4).

Just checking what the 12z ICON days for fun for Wednesday to Friday at DCA... oh. 103/106/106... HI values 110-115

Even 06z Euro has low 100s for most of the region on Wednesday

Quite possible yes, but 06z GFS is also quite toasty for Wednesday into Saturday - using 18z 2mT at DCA: 99/101/102/97 I see what you mean on the 00z Euro... that is a big no thanks from me re 2mT. Mid 100s? Blech

I hope he enjoys watching Superman 3 today

AFD was making it seem like subsidence would make it dry... which would suck. I want storms with my high heat

Can't wait Morning ZFP from LWX for DC metro for next week WEDNESDAY...Sunny, hot with highs in the upper 90s. .WEDNESDAY NIGHT...Partly cloudy. Lows in the upper 70s. .THURSDAY...Sunny, hot with highs around 100. Heat index values up to 110.

Same here since this morning.. got 4 cloudflare 502 error message in past 10 minutes. Says bad gateway and that the problem is with the host website @dendrite

Looks like a quick line coming soon for you

Power is out at work lol... just chilling and waiting

Looks like the line in i81 corridor is strengthening a bit

Mesoscale Discussion 1253 NWS Storm Prediction Center Norman OK 1225 PM CDT Mon Jun 22 2026 Areas affected...portions of the central Appalachians into the Mid-Atlantic Concerning...Severe potential...Watch likely Valid 221725Z - 221930Z Probability of Watch Issuance...80 percent SUMMARY...Thunderstorms will increase in coverage and intensity over the next couple of hours. Scattered damaging wind gusts, isolated hail and perhaps a tornado will be possible through evening. A severe thunderstorm watch will likely be needed by 19z. DISCUSSION...Thunderstorms over the higher terrain of WV and vicinity are gradually increasing in intensity this afternoon as gradual destabilization occurs. Downstream from higher terrain across portions of VA into MD/DE, southern NJ and southeast PA, stronger heating is occurring within areas of mostly clear skies. Higher quality moisture across eastern VA has been streaming northward toward southeast PA/southern NJ and ensuing stronger destabilization is noted. Enhanced westerly flow is apparent in early afternoon mesoanalysis and 12z regional RAOBs. This should allow for sufficient deep layer shear for storm organization. Thunderstorm clusters will pose mainly a risk of damaging wind gusts given steep (greater than 7.5 C/km) 0-3 km lapse rates and PW values around 1.75 inches. Some forecast guidance suggests sufficient clustering/outflow consolidation may occur in the vicinity of northern VA/MD and a forward propagating cluster/bowing segment could develop and track northeast with time toward southeast PA/NJ. This corridor aligns with the corridor of stronger midlevel westerlies, and may pose a relative greater severe risk compared to points further south into southern VA and NC where flow is weaker. If this scenario unfolds, damaging wind potential will increase. Given modest 0-1 km SRH across the region, a tornado or two also could occur, though the damaging wind risk is expected to be the primary hazard into early evening. ..Leitman/Hart.. 06/22/2026 ...Please see www.spc.noaa.gov for graphic product...

12z NAM soundings would definitely suggest potential for tornadoes tomorrow afternoon into tomorrow night IMO

SLGT risk up for Monday on afternoon Day 3 @high risk @Kmlwx @Eskimo Joe ...Mid-Atlantic... Areas of showers and thunderstorms are expected to be ongoing Monday morning across the lower Great Lakes/upper OH Valley region. Ahead of that convection, a southwesterly low-level jet is forecast to migrate through the Mid-Atlantic, enhancing the poleward transport of an increasingly moist and unstable boundary layer. Increasing height falls/forcing for ascent coupled with convergence near and ahead of the surface low, cold front, and any existing outflow boundaries are expected to foster an increase in storm coverage and intensity by afternoon. Strengthening mid-level flow aloft will combine with backed, near-ground winds ahead of the surface low to enhance vertical shear across the DelMarVa region, supporting the potential for supercell storm modes capable of all severe-weather hazards.
