Fxus63 klsx 192247 afdlsx area forecast discussion... Updated aviation national weather service saint louis mo 547 pm cdt Mon aug 19 2019 Short term (through late Tuesday night) issued at 325 pm cdt Mon aug 19 2019 early this afternoon, the center of an upper ridge was located over the southern high plains with weak NW flow aloft over our region. At the surface, a weak frontal boundary existed across northern mo and into central il. Surface convergence is so weak along this front that it is struggling to result in any enhanced cumulus--in fact, no more than any other area, with the ozarks being more successful at a bit more convergence to result in scattered thunderstorm development there. A few isolated cells were also present in southern il near the i-70 corridor. Temperatures ranged from the upper 80s to mid 90s, with the highest values in the stl metro area where heat index values have exceeded 105 in many locations. Elsewhere, heat index values ranged from 100-104. The upper ridge is expected to maintain its position and strength through tonight as the weak surface front stalls into northeast mo and southern il. Further upstream, most model guidance continues to advertise the development of a MCS in western ia later tonight with the flow and surface frontal position then steering this complex southeastward overnight. There is a general consensus that this complex will remain north of the forecast area through 12z tue. Otherwise, expect the convection in southeast mo and southern il to weaken and dissipate early this evening, leaving behind clear skies for much of the night, but look for convective cloudiness to be on the increase from the northwest towards daybreak. Min temps tonight should be about 3-5f higher than persistence thanks to the presence of high dewpoints lingering that just aren't going anywhere, with readings bottoming out in the 70s. No real change on the upper ridge again during the day on Tuesday with the anticipated MCS in iowa expected to continue its southeastward track primarily through illinois, but it should have enough of a southwest tail on it thanks to the veering low level jet to result in many areas into eastern mo to justify likely pops. The timing on this is expected to be from 8am-2pm. Plenty of instability and environmental bulk shear for this complex to tap into, even in the morning, for severe storms to be an issue, with both large hail and damaging winds to be a concern. The rain and timing of it should also make attaining dangerous heat humidity levels very difficult, but if it happens anywhere, it will be in central and southeast mo along the far western periphery. Confidence is not high enough to issue any heat headlines yet and current forecast has 100-103 anyway. Temperatures in most areas will struggle to exit the 80s thanks to the clouds and rain, with even the current forecast too warm in spots if the rain fully verifies. In the wake of the mcs, it is expected it will be very difficult for any new development of precipitation thanks to the stabilizing effect. The upper ridge finally starts to break down Tuesday night. The old surface frontal boundary is expected to have washed out early in the period with a new cold front not expected to make much in-roads until late. High dewpoints are expected to linger for a muggy night

with min temps again in the 70s, similar to the previous night. Any rain chances should be in northern mo and central il near the front. Tes Long term (Wednesday through next Monday) issued at 325 pm cdt Mon aug 19 2019 the surface cold front is expected to move slowly through our region on Wednesday and be just south of our area on Thursday, resulting in what should be high pops for this period thanks to very rich moisture through the column. In addition, high instability present on Wednesday afternoon could result in another round of severe storms. The timing of the front and how fast it produces storms on Wednesday will be key, because a slower movement onset also could result in another day of concern for dangerous heat humidity. Currently we have peak index values between 100-103 for many areas. Heading later into the week and into the weekend, surface high pressure is expected to nose into our area enough with its cool and dry easterly flow to minimize rain chances while keeping temperatures below normal, with highs for Friday through Sunday in the upper 70s to lower 80s most areas. Only on next Monday is there significant divergence on the upper pattern, with some models showing the upper ridge expanding back into our area, while others keep us more under the influence of a trof from the northern plains instead. Temperatures should return to more normal values in the mid to upper 80s thanks to southerly flow returning, along with rain chances. Tes Aviation (for the 00z tafs through 00z Tuesday evening) issued at 539 pm cdt Mon aug 19 2019 this afternoon's scattered storms should end within the next few hours. Aviation concerns beyond that are twofold. First is the potential for fog in the early morning hours. With high dewpoints, light winds, and clear skies expected for much of the area in the early morning hours, the table appears to be set for at least patchy fog. The other primary concern is due to a line of strong storms expected to push through western and central il in the late morning hours. Storms seem quite likely at uin, with the stl metro terminals on the fringes of the highest precip chances. That said, storms may be decaying by the time they reach uin and i'm not sure just how poor flight conditions will get. While i've stuck withVFR at uin for tomorrow's storms, it's possible conditions drop to at least MVFR as the storms pass. The same could be said for the metro tafs, though again, storm chances are a bit lower over those areas. Bsh Lsx watches warnings advisories Mo...

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
