Area Forecast Discussion...Updated Aviation National Weather Service Saint Louis MO 625 PM CDT Thu Aug 25 2022 .SHORT TERM... (Through Late Friday Night) Issued at 159 PM CDT Thu Aug 25 2022 Latest surface analysis has showed that the front has moved into the far northern part of the CWA in response to a weak shortwave trough that is moving southeast across the Upper Midwest. Latest HREF is showing that this shortwave will move into the southern Great Lakes by late tonight that will act to push the surface front through the CWA by mid morning Friday. In the meantime, latest objective analysis is showing MLCAPES around 2000 J/kg along the front with little CIN and CAMS are still showing some scattered showers and thunderstorms developing over northeast Missouri as well as west central and south central Illinois this afternoon into this evening with isolated thunderstorms developing as far southwest as the St. Louis metro. The best ascent with the shortwave will stay northeast of the CWA and shear is expected to stay weak, so the threat of strong/severe storms remains limited. Overnight into early Friday, rain chances look limited as weak subsidence sets in over the area. Have kept a slight chance of showers and thunderstorms on Friday afternoon over southeast Missouri which will be relatively close to the lingering front. Lows tonight will be in the mid-upper 60s as the front moves slowly south across the area. Highs tomorrow behind the front will be a few degree cooler but still close to normal. Britt .LONG TERM... (Saturday through Next Thursday) Issued at 159 PM CDT Thu Aug 25 2022 Saturday continues to look dry at this point as the GFS/ECMWF/CMC are showing the surface high lingering across the area. An unsettled weather pattern still looks like it will set up beginning on Saturday night that will continue into early next week. There is still decent agreement between the GFS and ECMWF that an upper trough will move across the Midwest on Sunday at the same time that a warm front will lift north through Missouri and Illinois bringing a chance of showers and thunderstorms over parts of the area from Saturday night into Sunday night. The deterministic models are also showing a upper low dropping down into Plains by early next, but with differing solutions on whether the upper low will become cutoff over the central Plains or become more amplified with a deep trough over eastern North America and ridge over the west. The ensemble means of the aforementioned models would favor a more amplified solution which would bring a cold front southeast through Missouri and Illinois on Tuesday when the main trough is likely to move across the area. The best chance for showers and thunderstorms will be Monday into Tuesday ahead of the front, but could continue to see a scattered showers and a few thunderstorms that could last into Wednesday. Temperatures over the weekend into early next week are expected to be at or just above normal as 850mb temperatures will be in the 18- 20C range ahead of the cold front. This is reflected well with the NBM and raw model temperature guidance which shows temperatures warming up over the weekend, but then shows a increasing spread between the 25th/75th percentiles which reflects the uncertainty given the model differences early-middle next week. Britt && .AVIATION... (For the 00z TAFs through 00z Friday Evening) Issued at 611 PM CDT Thu Aug 25 2022 A cold front is slowly drifting south across the area and has sparked an area of thunderstorms north of St. Louis. I'm not certain how long these storms will persist or if they will make it to any of the St. Louis terminals. However I suspect the storms will begin to dissipate soon, or at the very least move more eastward than southward, Given that the storm's outflow has begun to push well south of the storm itself. Winds along the outflow should likewise diminish as it pushes further away from the storms, but it may cause winds to turn to the north at the STL area terminals. Storms will continue to diminish this evening, leaving weak northerly winds in place through the remainder of the TAF period. BSH && .LSX WATCHES/WARNINGS/ADVISORIES... MO...None.
