Area forecast discussion, Jun 26, 6:42 PM CDT, 2 hours 44 minutes before
Area Forecast Discussion National Weather Service La Crosse WI 642 PM CDT Tue Jun 26 2018 .SHORT TERM...(Tonight trough Wednesday) Issued at 152 PM CDT Tue Jun 26 2018 GOES-East Water Vapor imagery showing a closed low moving east through northeast IA. This low will move east of the area this evening, ending shower/scattered thunder threat by midnight or soon after. Models showing a lot of low clouds forming across the area tonight in the wake of this low and rainfall that fell today. This stratus looks to hang on through tomorrow morning, dissipating during the afternoon as high pressure builds overhead. Look for highs in the upper 70s to the lower 80s with northwest winds generally less than 10 mph. .LONG TERM...(Wednesday Night through Tuesday) Issued at 152 PM CDT Tue Jun 26 2018 Main forecast concerns for this period are increasing temperatures for the latter part of the work week and into the weekend, as well as shower and storm chances, especially on Saturday. Upper level ridging will continue to build into the area on Thursday. Models are in decent agreement of shortwave trough riding over the ridge, but associated showers and storms look to stay south of the forecast area, mainly in central into southeast Iowa. Pressure gradient then tightens Thursday evening behind departing surface high pressure and ahead of approaching surface low pressure, leading to strengthening southerly winds and warm air advection for Friday. Forecast soundings show good mixing to near 850 mb, where temperatures are progged to be in the 24-26 C range through much of the area. Mixing this down to the surface, could easily see gusts near 30 kts and temperatures well into the 90s. In addition, looking at good moisture return with the southerly flow, with dewpoints into the 70s (the 26.12Z GFS even has lower 80s, but not buying that at all). Should be enough for heat index values over 100 and at least a heat advisory for much of the area on Friday. Should temperatures trend a bit higher, an excessive heat warning wouldn't be out of the question. Attention then turns to Saturday as a cold front slides into the area. MUCAPE (5000+ J/kg) from the GFS is overdone given the extremely high dewpoints, but the 26.12Z ECWMF still develops 2500- 3000 J/kg through the area, so plenty for storms to get going. The strongest deep layer shear looks to be behind the front, but could be strong enough right along the front for at least some organized strong storms. Any precip looks to be out of the area by late Sunday morning with a return to temperatures in the upper 70s to lower 80s for the end of the weekend and into the work week. Models diverge a bit for the beginning of the work week in regards to precipitation. The 26.12Z GFS brings in another shortwave trough and associated precip Monday evening into Tuesday, while the 26.12Z ECMWF slides it north of the area. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 642 PM CDT Tue Jun 26 2018 Currently watching some scattered showers and isolated storms that are east of KRST, but slowly rotating northeastward toward KLSE. Think KLSE will see some impacts from rain and reduced visibility/ ceiling over the next couple hours before all convective activity moves east and diminishes after sunset. Focus then moves to low ceilings/fog potential overnight. Most forecast guidance develops low stratus/patchy fog across the region, but questions remain on timing and cloud base height/ visibility restrictions. Won't stray too far from 18Z TAFs for now, but amendments are possible through the evening. Lower MVFR ceilings are expected to persist into the day on Wednesday before gradually lifting. Winds through the period will be light. Variable/calm winds overnight will pick up slightly Wednesday from the northwest. && .HYDROLOGY... Issued at 152 PM CDT Tue Jun 26 2018 Showers and storms have been very transitory and so far today and have not been prolific rain-makers. Threat of heavy rain shifts east of the area this evening. Otherwise, the flood wave will continue to moving south along the Mississippi River, causing minor flooding from Wabasha south through McGregor.
