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 Milwaukee, WI wrote its last area forecast discussion before this river flood warning went out at Apr 26, 6:09 AM CDT, 40 minutes earlier.
Area forecast discussion, Apr 26, 6:09 AM CDT, 40 minutes before
Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 609 AM CDT Thu Apr 26 2018 .UPDATE...No changes at this time. && .AVIATION(12Z TAFS)...Thin cirrus continues to move south across Wisconsin ahead of approaching weak cold front over the northern Plains. Low level cold air advection in wake of front may bring a period of MVFR clouds to eastern areas later tonight. Otherwise, VFR conditions expected for the majority of the forecast period. && .PREV DISCUSSION... (Issued 337 AM CDT Thu Apr 26 2018) SHORT TERM... TODAY AND TONIGHT - Confidence...Medium to High. Warmer temperatures will return to southern WI today. A developing south to southwest breeze in the low levels ahead of an approaching cold front will result in 925H temps peaking in the 10 to 12C range. Daytime temperatures should peak in the mid to upper 60s most locations. Dry conditions are expected for today due to ridging ahead of approaching weak system. However, cirrus ahead of this system will spread across southern WI, but should remain fairly thin resulting in the warmer temperatures. A fluctuating lake breeze will keep lakeshore areas a few degrees cooler, but not nearly as cool as yesterday. The cold front will pass through southern WI during the evening. Enough of an increase in low to mid level moisture and synoptic scale lift as it passes through to warrant lower chances for showers. Instability remains negligible so wl not include thunder mention. Short term guidance in good agreement on period of high rh and weak sloping layer frontogenetical forcing sliding through with front. The shower threat will be brief with dry conditions returning after midnight due to short wave ridging ahead of approaching stronger short wave for Friday. LONG TERM... Friday through Saturday... Forecast confidence is Medium. A mid level shortwave trough will barrel through the Upper Great Lakes Friday afternoon. Timing of this wave is a little uncertain between the models, but scattered to numerous rain showers are expected with this potent system, most likely during the afternoon hours. The trend of the surface low track has been sliding south which means more of south central and southeast WI is in the area targeted for widespread showers. Steep low level lapse rates could lead to a few rumbles of thunder as well, and temperatures aloft will be quite cold so there may be some graupel or small hail mixed in. Precip will exit by mid evening, but low clouds could hang around through the night. There might be some light snow toward east central WI as the precip tapers off. The upper trough will linger over the Great Lakes through Saturday, so expect a few diurnal cumulus clouds around, especially toward the lakeshore. More sunshine inland and no lake influence will allow temps to get into the mid 50s. Sunday through Monday... Forecast confidence is Medium. High pressure and increasing southerly flow for the first half of next week will usher much warmer air into southern Wisconsin. Sunday will be dry with highs in the 60s inland from the lake. There will be weak enough flow to allow for a lake breeze. There is more uncertainty to Monday's forecast as the ECMWF introduces rain with a leading shortwave over WI while the GFS keeps the low layers drier and therefore has a dry forecast for southern WI. I'm leaning toward the dry forecast since there will be a lot of dry air to overcome. If we end up with the drier scenario, temperatures will be even warmer than the forecast lower 70s. Tuesday and Beyond... Forecast confidence is Medium. An approaching low pressure system from the Northern Plains will bring showers and thunderstorms to the Upper Midwest. Depending on the speed of this next system, Tuesday may remain dry and very warm with highs in the mid 70s, but dewpoints will be on the rise. There is better agreement between the models about precip timing Tue afternoon into Wednesday. The next system of interest is a large low ejecting from the Plains and bringing a lot of moisture into southern WI Wednesday night into Thursday. This system would bring thunderstorms to the area. AVIATION(09Z TAFS)...VFR conditions are expected into this evening. A light shower is possible from some lower VFR clouds this evening. The main concern is a burst of low level cold air advection behind a passing cold front. A brief period of MVFR clouds may accompany the cold air push in the eastern CWA later tonight. MARINE...Light offshore winds early this morning will become southeast later this morning as the land surface rapidly warms creating a tight temperature gradient at the shore. Near shore winds will become more south to southeast this afternoon ahead of approaching weak cold front. This cold front will pass across the near shore waters this evening causing winds to turn to the north to northwest. A brief burst of higher winds are expected with gusts possibly reaching 20-22 knots. An isolated gust may reach 25 knots. However will hold off on Small Craft Advisory for tonight as wave heights are expected to remain low and short term guidance in disagreement on strength of winds behind cold front. There is a better chance for gusts reaching 25 knots behind a passing low pressure system Friday night into Saturday morning. FIRE WEATHER...Warmer temperatures return today with a developing south to southwest breeze later this morning and afternoon. Breezes will likely reach 12-15 mph as temperatures warm into the mid to upper 60s away from Lake Michigan. Relative humidities remain tricky today. Atmosphere ahead of approaching front looks to remain dry so expect dewpoints to fall into the mid 20s to lower 30s across southern WI as moist soil and remaining snow pile melt having little recent affect on dewpoints. Hence expect humidity values to fall into the 20 to 30 percent range later this morning and afternoon. With Fine Fuel Moisture Code values expected in the 90-92 range, conditions for wildfire development will be "elevated". && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
