SHORT TERM. (Through Late Sunday Afternoon) Issued at 315 AM CST Sat Jan 25 2020

Cyclonic flow will continue today in the wake of the upper low departing the OH Valley. Stratus blankets the region within this flow extending back into eastern KS. I think clearing will be slow and am leaning towards the more pessimistic guidance suggested by the RAP 925 mb RH. This would bring potential clearing first into the southern CWA later this afternoon which seems reasonable given the notch in the stratus over far SW MO at this time. The combination of the stubborn low clouds and weak low level CAA will make for a small diurnal temperature range for all but the aforementioned southern CWA where afternoon clearing is expected. All in all the highs today will be on the order of 3 to 10 degrees below average.

The stratus should continue clearing eastward across the CWA tonight. However the low clouds will be chased by increasing mid- high clouds spreading in from the west-northwest in advance of several northwest flow short wave trofs with the progressive split flow pattern. The main waves pass to the north and south on Sunday. The 00z ECMWF is quite a change from 24 hours ago when it showed light precipitation across the entire CWA. All the models are now in rather good agreement keeping any precipitation south of the CWA, more in line with the better forcing across the lower MS and western TN Valleys. That said we will still need to keep an eye on the far southern CWA counties for any fluctuations in location of the forcing and moisture, and possibility of light precipitation.

LONG TERM. (Sunday Night through Friday) Issued at 315 AM CST Sat Jan 25 2020

Much of the week ahead looks dry with the progressive split flow regime continuing into late week. There is a rather potent short wave trof forecast to move across the region on Monday that bears watching. Timing varies a bit with this system but it does have some decent large scale forcing, and the CMC GEM is the sole model showing the possibility of a quick hit of light snow with a band across central and east central MO.

Another series of migratory short waves are forecast to traverse the area Tuesday night into early Wednesday. The global models and GEFS have been trending drier in this time range with a growing consensus that the waves won't phase and precipitation will largely be associated with the southern wave across the lower MS Valley.

A pattern change begins to evolve late week into the weekend featuring large scale amplification. In the process we could see some precipitation and at least a short period of above normal temperatures.

AVIATION. (For the 12z TAFs through 12z Sunday Morning) Issued at 526 AM CST Sat Jan 25 2020

Model guidance in good agreement showing the stratus currently over the area lingering through much of the day before eventually rotating northeast out of the region late this afternoon and overnight, with cigs remaining between 1,000 and 2,000 ft through much of the day. It's likely that a few terminals briefly dip back to IFR at times this morning, but I think we'll largely remain MVFR today. Given the low bias in forecast cigs over the last 12 hours, I wouldn't be surprised to see cigs exceed 2kft at some point today, especially this afternoon.

As the current stratus deck begins to move out, mid-level cloudiness will filter into the area this evening and overnight. Additionally, several high res models show the low level clouds currently over the Northern Plains advecting into our area in the early morning hours on Sunday. I'm not confident on just how low or widespread these clouds will be as they reach the mid- Mississippi Valley, but model consensus too strong to ignore. Therefore have dropped cigs back to MVFR toward the end of the TAF period and included a SCT009 mention to hint at the possibility of some IFR cigs tomorrow morning. There is also a chance for some fog development with this area of low level moisture, but confidence is too low to mention it in the TAFs.

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.
