What forecasters said that day
The local office's own words before this flood watch 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 flood watch went out at Oct 8, 2:40 AM CDT, 33 minutes earlier.
Area forecast discussion, Oct 8, 2:40 AM CDT, 33 minutes before
Area Forecast Discussion National Weather Service La Crosse WI 240 AM CDT Mon Oct 8 2018 .SHORT TERM...(Today through Wednesday) Issued at 240 AM CDT Mon Oct 8 2018 No change in what has been well forecast for the past week with a soggy few days ahead for the Upper Mississippi River Valley - with heavy rain and flooding (river/stream) concerns into Wednesday. West coast trough continues to sharpen with east coast ridge amplifying - keeping the region locked into a freeway of shortwaves moving north/northeast out of the trough. At the sfc, a warm front lies to the south while what looks to be an inverted trough runs north-south Dakotas/western MN area. Not that defined. The boundaries look like they may gradually coalesce into a north-south running boundary later tonight as the warm front gets some movement north and the flow a loft become more north-south. This boundary then anchors roughly from northwest WI into southern IA - with the parade of shortwaves running across it. In addition, the upper level jet will enhance this available lift into Wed with persistent upper level divergence. For fuel, steady flux of low level moisture transport with periodic surges of the 850 mb jet. Prolonged period of fairly persistent rain will be the result, with pockets of moderate to heavy rain at times. As for thunder chances, not a whole lot of instability to play with, and what there is is mostly east of the front, in the warm sector. One period of interest is later Tue afternoon/evening with the NAM and GFS building close to 1000 J/kg of MUCAPE, overlapping with 30- 40 kts of 0-3 km shear. Deeper shear more northwest into the colder air. A decent shot for a few stronger storms, and perhaps isolated severe. Otherwise, the main severe concern for the next few days is the river/stream flooding for repeated rounds of rain. More on that in the hydrology section below. Dialing back to this afternoon - some of the meso models are sparking a thin line of storms in the vicinity of the warm front and on edge of bubble of instability. Recent HRRR runs are pretty aggressive with developing this line by mid/late afternoon across eastern IA into southwest WI. Other models aren't nearly as aggressive, but generally suggest something could go up. RAP showing upwards of 40 kts of 0-6 km shear where it develops some storms. If they go, would seem to be enough for at least some stronger storms, and some threat for severe. Evolution will have to be watched closely today. .LONG TERM...(Thursday through Sunday) Issued at 240 AM CDT Mon Oct 8 2018 Models remain in good agreement with pattern shift for the later half of the week, shifting from southerly to a northwest flow a loft. Both the GFS and EC suggest shortwaves will move southwest out of Canada and spin across the Upper Mississippi valley during this period - one on Friday and the other Sat night/Sun. The Friday system will have to battle a sfc high across the south, and that will help limit saturation for the shortwave to work on. With the high exiting southeast by Sat, the weekend system won't have that to compete with. While trends still favor at least a few days of drying out for the local area (Wed night-Sat), some shower chances look to creep back in by Sunday, potentially into the start of the new work week. General cyclonic flow a loft and low/mid level cooling/good lapse rates suggest at least an afternoon threat for some showers. The northwest pattern shift also brings much colder air to round out the week, with shots of low level cold air advection Thu/Fri and again Sun-Mon. 40s/50s for highs with lows mostly in the 30s are expected. For those that have not had a killing frost, that could/will occur this weekend. Freezing temps also a distinct possibility - highlighted for Friday morning. && .AVIATION...(For the 06Z TAFS through 06Z Monday night) Issued at 1106 PM CDT Sun Oct 7 2018 Rounds of showers and drizzle will continue to work north across the area the next 24 hours, briefly heavy at times, as widespread low stratus also remains in place. Ceilings should continue to dip to LIFR levels at RST and IFR at LSE, only very slowly improving into the afternoon on Monday before potentially dropping to LIFR again at RST into Monday evening. Winds remain from an easterly direction, generally 5-10 knots. && .HYDROLOGY... Issued at 240 AM CDT Mon Oct 8 2018 Still looking at a summer-ish airmass for the start of the new work week...pws pointing upwards of 1.75 inches with warm cloud depths around 3.5 kft. Favorable for efficient rain production during the summer, real good for early fall. Mostly though, amounts are going to be heavily factored by time and residence of the rain - basically, where the north-south bands set up and "sit". Models have trended toward putting this axis from northcentral WI into western IA. The GFS has generally been more west compared to the EC/NAM. Locally, the favored locations run from northeast IA, through southeast MN into north-central WI. Thankfully, hard hit locations of southwest WI and bordering IA counties may be spared the higher rainfall amounts. That said, some convective risks - if realized - could drop some quick heavy rainfall in these locations this afternoon/Tue. Perhaps a threat for flash flooding here. Something else to monitor. There will be a flooding threat where the higher amounts fall, but look more areal-river/stream related rather than "flash". If trends continue to favor the rain just west/north, those areas will need a day or two to saturate and then runoff can begin more in earnest. With this in mind, will issue a Flood Watch for these potential impacts. Confidence fairly high that there will be impacts for some river systems. && .ARX WATCHES/WARNINGS/ADVISORIES...
