Area Forecast Discussion . UPDATED National Weather Service Jackson MS 1129 AM CST Thu Dec 5 2019
UPDATE. Updated for 18Z aviation discussion
AVIATION. 18Z TAF discussion: VFR conditions will prevail at all sites throughout the day today. Then expect some lowering ceilings early tomorrow morning after 09z due to low clouds moving in with this system. With this, -RA will also become increasingly likely from west to east. /JNE/
DISCUSSION. Quiet weather will persist through today as a high pressure is still centered over much of the ArkLaMiss. Some high clouds are building in currently in the west but won't be of any concern for today. Not much needed to be changed, the previous forecast was very much on track. Highs will be in the upper 60s for most of the area and near 70s in the southwest./JNE/
Prior discussion below:
Today through tonight: Forecast guidance has not wavered much in showing a that a shortwave trough will approach the area later today and tonight. Developing return flow will bring milder temperatures and increasing clouds, but shower chances are not expected to increase in earnest until close to daybreak Friday. Convective instability should be just enough to support getting a few storms by that time, and moisture transport could support a few heavy downpours, but no significant impacts are expected with rainfall totals generally less than an inch on average given the progressive nature of the system. /EC/
Friday through next Wednesday: As we begin the period Friday, the previously mentioned shortwave trough will be in the process of shifting east southeast across the Ozarks and through the forecast area during the course of the day. At the surface, this will result in a surface low developing and racing east southeast into and across the forecast area from early Friday morning into Friday evening. Showers, along with a few isolated storms, will likewise spread across the CWA during this time, with rain chances ending over eastern portions of the forecast area late Friday night.
Behind this system, northwest flow will again advect a slightly cooler drier airmass into the region for the first half of the upcoming weekend. The aforementioned system looks to hang-up over the North Central Gulf of Mexico Saturday. A series of subtle disturbances aloft will traverse the region, as the once stalled system washes out, and the remaining moisture associated with it gets pulled northward across Alabama. This could potentially bring an isolated shower or two to portions of East and Southeast Mississippi Sunday and Sunday night.
As we start the new work week, a broad trough will drop southeast out of the Intermountain West into the Great Plains Sunday night into Monday. This will result in flow aloft across the CWA increasing, in addition to an increase in isentropic upglide ac. ross the region. This will bring an increase in rain chances across the forecast area Monday.
These rain chances will persist into Tuesday as the trough swings east through the region. This will push a cold front southeast into and across the forecast area overnight Monday into Tuesday. Rain chances will gradually come to an end Tuesday night. High pressure will build back into the CWA Wednesday from the northwest, resulting in a return to cooler drier conditions. /19/

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
