Area Forecast Discussion National Weather Service Jackson MS 541 AM CDT Wed Aug 5 2020

UPDATE. Updated for 12Z aviation discussion

AVIATION. 12Z TAF discussion: Aside from a few patchy areas of early morning fog, VFR conditions and light northerly surface winds will prevail through the forecast period. Isolated SHRA activity is not out of the question over eastern MS this afternoon. /EC/

DISCUSSION.

Today through tonight: The persistent upper level trough over the ArkLaMiss region will slowly shift east in the near term. North- northwesterly flow will continue to advect in anomalously dry mid/upper level air over the forecast area with precipitable water values (< 1.25 in) rather paltry for mid summer. The relatively dry air combined with subsidence should mostly preclude diurnal convective precipitation, but there may be enough instability to stir up isolated shower development over eastern MS. Otherwise, it appears any new convection associated with an MCV approaching the ArkLaTex region this morning should remain west of the forecast area through the near term. /EC/

Thursday through next Tuesday . Expect mostly dry conditions through the end of the week as high pressure ridging will be in control across the area. Highs Thursday and Friday will be in the low to mid 90s, with dew points remaining in the 60s. Moisture will be increasing this weekend into early next week as southerly flow returns, with dewpoints edging back up into the lower 70s. Although highs will continue to reach the low to mid 90s each day, heat index values should remain below 105 for most locations. Diurnal convection will also be on the increase this weekend into early next week. /27/

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 numerous 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.
