DISCUSSION

Issued at 104 AM CDT Sat Jun 6 2026

After a long period of blocked up flow aloft with stable and dry conditions a more pronounced pattern change appears to be underway this weekend. Strong and broad troughing entering the US west coast is moving a closed low over Texas northeastward towards the area. Rain chances start to perk up ahead and under this trough. Guidance is mostly dry for the day today but there does appear to be some elevated instability available from parcels around 700mb that may lead to a few stray showers in the afternoon before chances peak Sunday morning with more widespread shower and thunderstorm activity.

With modest jet-level ascent and at least some instability shower and storm chances continue then until peaking once again Monday afternoon. PWAT values will be about 1.8 to 2.0 but both large scale ascent and instability for now look too limited for a widespread heavy rain threat as the primary trigger for showers and storms are a weakening upper shortwave and modest lower layer warm advection. Severe weather also looks pretty unlikely given the aforementioned weak instability and relatively weak deep and low layer shear.

Once this system clears surface ridging sets up over its climatological default position off the east coast and 500mb heights increase to around 590 dm with light to moderate southwesterly winds pumping in soupy air from the southwest as summer time firmly grabs hold of the area for a few days. Troughing over the north central US does look to potentially send a front or weak ripples in the flow this way by the end of the week. By Friday this system in 00z deterministic guidance starts to line us up in a rainier stormier pattern once again.

VFR conditions are forecast through the day. Isolated to scattered showers will be possible overnight but probability does seem to be trending lower and is too low for TAF mention right now.
