NWS La Crosse, WI wrote its last area forecast discussion before the first event at Jun 30, 11:01 PM CST, 59 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service La Crosse WI 1201 AM CDT Tue Jul 1 2025 .KEY MESSAGES... - Scattered showers/storms mid afternoon into early evening, Severe not expected. - Dry Tuesday!!! - 4th of July holiday weekend shaping up to be "active" - moreso for the start. Shower/storm chances move in later Fri night through Sat. Fireworks could be impacted for some. Sun is trending dry. && .DISCUSSION... Issued at 105 PM CDT Mon Jun 30 2025 > AFTERNOON/TONIGHT: scattered showers/storms into mid evening Upper level shortwave trough will continue to drop southeast across MN this afternoon (per watervapor satellite imagery), spinning across western/central WI by 00z. RAP builds as much as 1500 J/kg of SBCAPE ahead of the shortwave while also showing a bit of a push from a southeast running 850 mb jet, nosing into SE MN by 00z. Shear likely not a player locally, mostly in the 3-6 km layer but likely displaced ahead of the instability. Expect scattered convective to push in/pop by mid/late afternoon (3-5 pm), tracking southeast and exiting the local area by 8-9 pm (if latest HRRR holds true). Not expecting severe weather. > TUESDAY: shaping up dry! Hopefully we didn't jinx it... A sfc high will be sliding southeast across the central/southern plains with broad upper level ridging hanging west across the rockies. The setup favors keeping any perturbations in the flow north of the forecast area - with the promise of a dry day. Probably going to hear a lot of lawn mowers. > WED INTO THE HOLIDAY WEEKEND: smattering of rain chances into Fri, greater threat for showers/storms late Fri night into Sat. The GEFS and EPS take the upper level ridge east, sliding over the upper mississippi river valley by Friday morning. Some rain threat still exists as bits of shortwave energy, mcvs, lingering sfc boundaries etc could still provide enough 'umph' to the summery atmosphere to pop some convection. Where/when/if showers/storms manifest into Friday are far from certain - although the EPS/GEFS members favor keeping much of this threat north of I-90. The 4th of July weekend is looking more active. An upper level shortwave trough is progged to move off the west coast and across the northern plains by 00z Sat. Not particularly strong in most of the ensemble guidance (which the WPC clusters also suggest), and could shift north of the local area. However, a cold front will reflect at the sfc and slip across the region. Building instability and increasing moisture/transport provide a good environment for storms. Wind shear fairly meager at this time - limiting a severe risk. As of now, late Fri night through Sat harbors the higher rain chances - with some potential to impact the 4th of July fireworks for some. Sunday is trending dry. Those with outdoor plans this holiday weekend (which is probably a majority of us) will want to keep a close eye on the forecast as we move through the week. && .AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/... Issued at 1158 PM CDT Mon Jun 30 2025 VFR conditions expected for the next 24 hours. Patchy fog should begin to develop across portions of West Central Wisconsin and Southeastern Minnesota into the overnight hours but this should stay out of the terminals. Light west/northwest winds overnight will become more northwesterly through tomorrow morning, picking up to around 10 kts by the afternoon. Winds will come back down during the evening as the nocturnal inversion builds back in. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...None. MN...None. IA...None. && DISCUSSION...Rieck AVIATION...Barendse
