SHORT TERM. (Sunday through Tuesday) Issued at 338 AM CDT Sun Sep 20 2020

After two consecutive days of cool, fall-like conditions throughout the region, temperatures are expected to begin a muted but noticeable increase today that will continue through Monday and level off on Tuesday. This will come courtesy of a building high amplitude ridge of high pressure aloft, which will replace the persistent northwest flow that has presided over the upper Mississippi Valley for the past several days. Afternoon high temperatures will rise about 3 to 5 degrees today when compared to yesterday, and another 2 to 4 degrees Monday, which will bring afternoon temperatures to very near seasonal averages. Meanwhile, the return of southeasterly low level flow will bring a modest increase in surface moisture, which will help to moderate overnight low temperatures as well. Instead of morning lows in the 40s, a return to a more seasonal mid 50s can be expected by Tuesday morning.

While this pattern shift will bring about temperature changes, precipitation chances remain bleak through Tuesday thanks to the persistence of high pressure and a dry, stable airmass. In short, expect pleasant and dry conditions Sunday through Tuesday, with no notable weather impacts expected. Meanwhile, smoke aloft will continue to drift across the region with varying degrees of opacity, and minimal impacts to air quality at the surface.

LONG TERM. (Wednesday through Saturday) Issued at 338 AM CDT Sun Sep 20 2020

While the upper level ridge will slowly deamplify Monday and Tuesday thanks to a passing shortwave across the northern plains and upper Mississippi Valley, this not expected to appreciably impact sensible weather until Wednesday. At this point, the ridge axis will begin a very slow westward retrogression that will occur over a period of several days, and will weaken overall as it does so. In what is a relatively sudden development in latest model guidance, this weakness in the ridge may provide a window for remnants of tropical storm Beta, perhaps combined with an additional weak disturbance, to move northward and into southern Missouri/Illinois Wednesday. While previous model guidance has hinted at this eventuality in prior runs, the vast majority of ensemble members had previously maintained that this was much more likely to occur later in the week or early next week, and maintained dry conditions through Wednesday at a minimum. In any case, there is a clear trend toward an earlier northward push of tropical moisture from Beta, with enough ensemble members to justify adding slight chances of rain across areas roughly south of I-44 Wednesday. On the other hand, there remains a significant amount of variability among ensemble members, and the ECMWF does appear to be a wet outlier among available guidance. This trend also appears to be dragging down expected high temperatures for Wednesday, likely due to the increase in cloud cover and precipitation, with a relatively tight clustering of members favoring near to slightly below normal afternoon highs Wednesday and Thursday.

That is a lot of words describing what still amounts to low probabilities of precipitation Wednesday, and even lower probabilities of negative impacts, but should this trend continue higher probabilities may be warranted.

Beyond Wednesday uncertainty increases significantly, although there are some clues we can gather from latest trends. With the retrogression of the upper level ridge to the intermountain west, and its eventual amplification, a longwave trough is still expected to dig into the eastern U.S. However, this will likely be delayed until late in the weekend or early next week, and as a result, a warming trend is expected to resume Thursday and continue through the weekend with little interruption from passing cold fronts. Precipitation chances remain variable during this time, but probabilities Thursday and Friday appear to be low overall. Probabilities for precipitation and lower temperatures increase gradually over the weekend and into early next week, likely the result of the return of northwest flow aloft and the arrival of one or more cold fronts.

AVIATION. (For the 12z TAFs through 12z Monday Morning) Issued at 600 AM CDT Sun Sep 20 2020

For the most part, clear skies, light winds, and VFR conditions can be expected through 12Z Monday morning.

The lone exception, once again, will be the development of shallow fog in river valleys, which returned to KSUS and KCPS early this morning after a brief hiatus. While this fog will dissipate quickly after sunrise, additional patchy fog development is likely again overnight Sunday through early Monday morning. This may result in brief dips to IFR visibilities in the usual terminals like KSUS and KCPS, and possibly KCOU as well, but is not expected to impact KSTL. Otherwise, no significant surface weather impacts can be expected today.

High elevation smoke will also remain present in the region, but this is not expected to impact visibilities near the surface.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.
