GosselinWhat 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 St. Louis, MO wrote its last area forecast discussion before this river flood warning went out at May 6, 5:59 AM CDT, 4 hours 46 minutes earlier.
Area forecast discussion, May 6, 5:59 AM CDT, 4 hours 46 minutes before
Area Forecast Discussion...Updated Aviation National Weather Service Saint Louis MO 559 AM CDT Fri May 6 2022 .SHORT TERM... (Through Late Saturday Afternoon) Issued at 449 AM CDT Fri May 6 2022 As daybreak draws near, a slow-moving shortwave continues to creep eastward along the southern border of Missouri, maintaining wet and unsettled conditions across the region. At first glance, this shortwave appears to be rather wrapped up and occluded on GOES water vapor imagery. However, model data and surface observations indicate that this system has not quite reached full maturity, as the surface low and upper low remain slightly offset and surface pressure continues to drop. In fact, it appears that divergent flow within the left exit region of the upper jet continues to drive cyclogenesis across southern Missouri, and is providing additional forcing for precipitation along the northern periphery of the surface low. Meanwhile, cooling aloft associated with the core of the upper low is also generating modest elevated instability, supporting scattered weak thunderstorms within the broader rain shield. The most substantial of this precipitation remains largely south of the I-70 corridor, but is expected to move slowly northeast through the remainder of the morning hours. Most of this rain will continue to be stratiform in nature, which will limit the rain rates to .50 in/hour or less in most areas. However, the previously mentioned modest instability coupled with PWAT values ranging from 1.1 to 1.5 in may result in locally higher rain rates within embedded convective cores. Given the ample recent rainfall that has already fallen, it remains possible that a few areas could see some localized nuisance flooding issues through late morning. By early afternoon, precipitation rates will rapidly diminish as the main area of forcing slides east. However, a few lingering wraparound showers will likely persist through the mid to late afternoon, mostly across eastern MO and western IL. Precipitation is expected to cease completely by early evening. Otherwise, expect another cool and cloudy day for many areas, with perhaps a bit of sunshine peaking through across central MO by the afternoon and evening. Chilly temperatures can be expected overnight, with lows falling into the mid 40s to low 50s area-wide. BRC .LONG TERM... (Saturday Night through Thursday) Issued at 449 AM CDT Fri May 6 2022 By Saturday, attention turns to major pattern change, one that will set the stage for an extended period of anomalous warmth across the region. As the previously discussed upper low wobbles eastward over the weekend, height rises will begin in earnest as an upper ridge rapidly builds across the central plains. Meanwhile, a longwave trough will dig into the western states, marking the beginning of what will be a persistent and amplified upper flow pattern across the CONUS. As persistent southwesterly flow aloft becomes established across the Rockies, a broad lee surface trough will develop across the high plains, which will begin the process of drawing southerly flow back into the plains and eventually the mid- Mississippi Valley. This will be a gradual process, though, as we will remain under the influence of a surface high through the day Saturday. As a result, light northeast winds will keep mild and dry conditions in place for one more day, with high temperatures likely only reaching near 70 degrees Saturday afternoon. To top it all off, clearing skies are also expected, resulting in an ideal springtime weather conditions to kick off the weekend. By Saturday night, the upper ridge axis will shift slightly eastward to align roughly along the Mississippi River, while a shortwave moves across the northern plains and eventually the upper Mississippi Valley. Meanwhile, southeasterly surface winds will ramp up in response to a tightening pressure gradient, and by Sunday morning an elevated warm front will begin to lift northeastward through the area. The combination of increasing moisture and the advancing warm front may provide a brief window for a few convective showers early Sunday, but widespread rain is not well supported by ensemble guidance, and chances for meaningful precipitation remain rather low. On the other hand, this advancing front will certainly bring a noticeable bump in temperatures, with highs likely reaching well into the 70s and perhaps even near 80 in the Ozarks and central MO by Sunday afternoon. This equates to around 5 degrees above seasonal averages, but we're still only scratching the surface of our expected warmup. As we head into the work week Monday, the upper flow pattern will continue to amplify, beginning a three day period of building heights and deep south to southwest flow across the central plains and Mississippi Valley. As a result, a persistent and anomalously warm airmass will move into the region, with 850mb temperatures near and exceeding the 99th percentile. This airmass will remain in place through Thursday, resulting in near record warmth throughout this period. Guidance continues to point to Tuesday as the warmest day of the week by a slim margin, but temperatures are likely to climb into the upper 80s and even the low 90s for four consecutive days. Even when accounting for a likely warm bias in the NBM, temperatures will almost certainly climb to the warmest readings we've seen so far this year. Meanwhile, the persistent ridge aloft and resulting subsidence will present a formidable obstacle to convection during this period, in spite of the steadily increasing moisture content. While we can't completely rule out a few rogue showers and even a thunderstorm or two during this timeframe, the forecast looks to be largely dry Monday through Thursday. BRC && .AVIATION... (For the 12z TAFs through 12z Saturday Morning) Issued at 552 AM CDT Fri May 6 2022 Low ceilings and showers continue to impact local terminals this morning, particularly in the St. Louis metro area. While observations have been somewhat variable, cloud bases have fallen to IFR levels in many areas, with a few dips to LIFR noted as well. This is expected to continue through the morning hours, with gradual improvement during the afternoon as rain showers gradually move off to the east. Some lighting has been noted across the Ozarks region this morning, but thunderstorms are not expected to impact any local terminals. Instead, expected periodic visibility reductions due to moderate rainfall and occasional fog, and little else. Precipitation will largely diminish during the afternoon. Skies will begin to clear first across central Missouri during the afternoon, followed by other areas during the evening and overnight. && .CLIMATE...
