10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

Updated aviation national weather service saint louis mo 550 pm cst Wed feb 20 2019 Short term (through late Thursday afternoon) issued at 304 pm cst Wed feb 20 2019 area remains under SW flow aloft through thurs with some weak ridging aloft tomorrow. At the surface, a weak ridge will build into the area tonight, with the axis lifting through the region thurs. Low clouds remain in place this afternoon, other than a few holes in the clouds that has allowed a brief period of insolation. Expect low clouds to clear out of the area early this evening. However, model solns continue to suggest high clouds moving back into the region this evening and becoming more widespread and thicker late tonight into thurs. Believe models also continue to hold on to too much snow cover today, with this lingering into tonight. Have therefore trended toward warmer guidance tonight. As the surface ridge settles over the area tonight, expect winds to become calm. With dewpoints above freezing, would expect any snow to continue to melt this evening, adding to the low level moisture. Currently, the best conditions appear to be across the southern half or so of the cwa. However, if northern portions can remain free of clouds longer, some fog may develop here as well. While not a great setup, have mention of patchy fog for these areas late tonight into thurs morning. For Thursday, believe many of the model 2m temps are again too cold due to the snow cover mentioned above. MOS is also in good agreement across the region for thurs. Regardless, with the ridge axis lifting north of the area, temps should rebound. Have therefore trended just below the MOS guidance for highs on thurs despite not being a great warming setup. Bsh Long term (Thursday night through next Wednesday) issued at 304 pm cst Wed feb 20 2019 upper level flow will remain out of the southwest from Thursday night until a potent shortwave pushes through the region on Saturday. The upper level flow will slide high pressure to our east on Friday morning, though a lingering baroclinic zone across the mid- south will keep the high north of the ohio river valley. This high position will keep our surface winds out of the east through the day on Friday, though winds are expected to quickly veer with height. South to southwesterly low level flow will begin to advect warm, moist air into the region on Friday. This lift and moisture will result in mostly clouds skies across the region and gradually increasing rain chances across southern mo and il through the day. Despite the WAA just above the surface, cloudy skies and easterly surface winds will conspire to keep high temperatures at or just below tomorrow's expected highs. The southerly low level flow will persist into Saturday ahead of the previously mentioned shortwave. This impulse is expected to result in rapid cyclogenesis across the southern plains before the low pushes through NW mo and into the great lakes by Saturday evening. With jet level winds approaching 140 kts and the low level jet topping 50 kts by Saturday afternoon, this extremely dynamic system has the potential to result in strong to severe thunderstorms across |
the mid-mississippi valley. However, all the moisture streaming in ahead of the low could keep skies mostly cloudy through the day on Saturday, limiting instability. Additionally, the previously mentioned baroclinic zone to our SE will likely limit surface based instability in our region and serve as a focus for the more significant, surface based storms. All that said, the current consensus low track should allow at least some elevated instability to bleed into the region, which coupled with the impressive dynamics, may give us our first severe weather event of the year. This thinking is backed up by the cips severe probability guidance, which has the entire CWA within a 15% contour and a 30% bullseye over southern il. Precipitation should quickly clear out of the area on Saturday evening as a robust dry slot punches into the region, but the potentially hazardous weather will not end there. The strong gradient flow will result in very gusty winds beginning Saturday evening before topping out near 35 kts early Sunday morning. Winds will then gradually diminish through the day on Sunday, but remain between 25 and 35 kts through noon. Those gusty post-frontal nw winds will drop Sunday's high 10-15 degrees compared to Saturday despite mostly sunny skies. Zonal upper level flow will then prevail through the first half of next week with high pressure dominating the lower levels. Winds will remain out of the north through Monday which will result in a very cold start to the week with lows on Monday morning in the teens and 20s. By Monday evening, winds will swing back around to the south and we'll briefly warm up to near normal on Tuesday. By Wednesday, a shortwave is progged to push through the midwest, pushing another cold front into the region. With that, we'll see temps drop back below normal and yet another chance for precipitation, some of which may be frozen. Bsh Aviation (for the 00z tafs through 00z Thursday evening) issued at 538 pm cst Wed feb 20 2019 an area of stratocu with cig heights from 2500-3500 feet persists from across much of western il through central and eastern mo. Both kuin and kcou are near the back edge and should clear out of the stratocu by 02z, with high clouds increasing later this evening and continuing into Thursday. The st. Louis area terminals should see the stratocu through late evening with flight conditions varying between high-end MVFR to low-endVFR, with high clouds then the remainder of the night and into Thursday. There is some question as to fog potential overnight into Thursday morning and I have kept with a tempo group for 5sm br give the uncertainty. Specifics for kstl: stratocu will continue through late evening with flight conditions varying between high-end MVFR to low-endVFR. High clouds are expected after the stratocu exits with the high clouds continuing on Thursday. I think the probability of fog overnight into Thursday morning at kstl is too low to mention at this time. Glass Lsx watches warnings advisories Mo... None. Il... None. Wfo lsx |

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.
