What forecasters said that day
The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS La Crosse, WI wrote its last area forecast discussion before this river flood warning went out at Apr 19, 12:26 PM CDT, 52 minutes earlier.
Area forecast discussion, Apr 19, 12:26 PM CDT, 52 minutes before
Area Forecast Discussion National Weather Service La Crosse WI 1226 PM CDT Thu Apr 19 2018 .SHORT TERM...(Today and tonight) Issued at 239 AM CDT Thu Apr 19 2018 Main short-term fcst concerns are temperatures today/tonight and fog potential later tonight (not wintry precip for a change). 06z data analysis had a broad area of low pressure centered over the mid Atlantic states to Can Maritimes and broad high pressure ridging thru the plains states. Mid level shortwave that brought snow to much of the area Wed was quickly exiting with the last of the precip already confined to northern IL. Clouds were clearing from north to south across the region, with clouds over the northern 2/3 of the region already limited to sct-bkn cirrus over MN. Where skies have cleared temps falling into the upper teens and 20s, with 18F already at KCMY over the fresh snow cover. 19.00z model runs initialized well. Model in good agreement for the longwave pattern to be progressive with ridging building east across the central CONUS, ahead of the next strong troughing digging into the SW CONUS. Short-term fcst confidence is good this cycle. For the short-term, after several days of winter weather headlines and bouts of wintry weather, finally a transition to quieter and warming weather. After the Wed system continues exit quickly east/SE overnight, the main features for today/tonight will be ridging building aloft and sfc high pressure building in from the plains. lower and higher clouds already clearing from the north as the system departs and northerly flow behind it spreads across the area. BL mixing/drying from the north should scour out any patchy fog early this morning as dew points drop into the teens. Deep, dry 925- 500mb airmass progged over the area today/tonight, with clouds limited to some cirrus ahead of a weakening shortwave dropping across MN. Northerly low level flow actually spreads a little low level warm advection in from the north today. Even so, there is another batch of fresh snow cover to melt and with high albedo. Models differ on depth of diurnal mixing today. Even with the snow cover, mid April sunshines should be able to mix to at least 925mb, with mixed 925mb temps supporting highs generally in the 40s. Center of the high is overhead tonight with light winds and what should be clear/mostly clear skies for some stronger radiational cooling over the snow cover. With BL moisture loading from the melting snow today, strong radiational cooling tonight and model soundings showing a shallow/strong low level inversion later tonight, added patchy to areas of fog across the entire fcst area later tonight into Fri morning. One more colder night tonight, with the blend of guidance lows mainly in the upper teens to mid 20s looking good. .LONG TERM...(Friday through Wednesday) Issued at 239 PM CDT Wed Apr 18 2018 For Friday thru Saturday night: main fcst concern this period is warming temperatures. Model runs of 19.00z in good agreement for ridging aloft to continue building across the Upper Midwest Fri thru Sat night as the southwest CONUS low/trough tracks to the lower MS valley by 12z Sun. Fcst confidence is good this period. A tranquil period of weather is set to continue Fri thru Sat night as ridging at the sfc and aloft remain over the region. Little low level warm advection this period with the center of the sfc-850mb high nearby and light flow. Airmass will continue to modify in place with late April sunshine. Snow cover/melting snow cover will continue to temper the warming Fri. Some mid/high clouds from the southern stream low trough expected to spill northeast across the region and temper the warming on Sat. For now, blend of guidance highs in the mid 40s to lower 50s Fri and mostly in the 50s for Sat look good. For Sunday thru Wednesday (days 4 to 7): main fcst concerns this period are warming temps Sun/Mon, mainly rain chances Tue/Tue night, melting snow and runoff and potential impacts on area rivers. Medium range model runs of 19.00z showing the ridging aloft to remain over the region thru Mon then reasonable agreement for a northern stream shortwave trough to drop into/across the Upper Midwest Mon night into Wed. Day 4-7 fcst confidence is average to good this cycle. Decent confidence for the dry, quiet, warming string of days to continue Sun/Mon with ridging aloft and the sfc ridge axis remaining over the region. 925-850mb ridge axis looking to slip far enough east of the area for at least some weak warm advection in SW low level flow Sun/Mon. Much of the snow cover should be gone by Sun, with mixed 925mb temps producing highs in the upper 50s to lower 60s Sun and mostly in the 60s Mon, near the late April normals! Shortwave trough to drop across Tue brings increasing moisture and cold front with it. Timing/detail differences as expected at the day 6/7 time range, but some mostly 30-50% rain chances Tue/Tue night good for now. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 1226 PM CDT Thu Apr 19 2018 Main taf concerns are the possibility of LIFR/IFR conditions at both RST/LSE taf sites. Surface ridge builds into eastern Minnesota and western Wisconsin this afternoon into Friday. This will provide light winds and mostly clear skies across the region through the taf period. VFR conditions are expected this afternoon into this evening. The combination of moisture from melting snow pack and an inversion developing tonight across the area...will allow fog to form at both RST/LSE taf sites by 06z Friday. At this time...have introduced IFR visibility restrictions at LSE taf site and borderline IFR conditions at RST taf site by 09z Friday. Fog is expected to dissipate by 15z Friday and for VFR conditions to prevail. && .HYDROLOGY...(This Weekend into early next week) Issued at 239 AM CDT Thu Apr 19 2018 More sunshine and warming temperatures today/Fri will produce snowmelt across the area. The snowmelt looks to accelerate Sat/Sun/Mon with even warmer daytime temps and nighttime lows only dipping to near or staying above freezing. Runoff from the melt will lead to rises on area streams and rivers. Besides the Trempealeau River at Dodge possibly exceeding flood stage this weekend, the rest of the area streams and rivers are expected to just see significant within-bank rises. Rises on the Mississippi River will be more into the middle and later part of next week as it will take some time for the meltwater from central MN and northern WI to flow south and reach our area. Those with interests or property close to streams and rivers will want to stay up to date on latest river forecasts in the coming week. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...None. MN...None.
