Area Forecast Discussion . UPDATED National Weather Service Shreveport LA 729 PM CDT Thu Aug 6 2020
A small cluster of showers and thunderstorms is riding SE along a lower tropospheric baroclinic zone, just to the north of the Four State region. The activity should remain out of the region this evening, although a few showers and a stray storm cannot be ruled out across McCurtain County and far southwest and south-central Arkansas (and the forecast received slight updates to include this potential). Otherwise, expect the northwest flow regime increasingly focused north of our region to kick up some late night showers and storms over eastern OK and western AR. Some of this precipitation could work south into areas mainly north of I-30 late tonight through tomorrow morning, as the prior forecast suggested. Aside from small-ish rain chances through early tomorrow in far northern zones, expect the region to remain mostly clear and dry through midday tomorrow with temperatures slightly warmer and muggier than was the case 24 hours ago. /50/

There could be a few showers and storms sneaking south/southeast into northern portions of the Four State region later tonight through the morning hours tomorrow, but all TAF sites are expected to remain dry. In fact, conditions should generally be all VFR at all sites with maybe two exceptions: at GGG and LFK there could be broken decks at 3 kft between 10AM through noon tomorrow, before cu decks scatter out and raise to a height of 4 to 6 kft. Expect winds generally from the south through southeast through tonight and less than 10 mph - remaining light tomorrow and backing a little more out of the east. /50/

SHORT TERM . /Tonight through Friday Night/
Aftn convection that appeared possible earlier this morning has yet to materialize. There does still seem to be a possibility that we could see a few isold shwrs/tstms develop, mainly across Deep E TX where low level moisture remains. However, any convection that is able to develop will quickly diminish by the start of the "tonight" period.
Nwly flow aloft continues across our region, as the upper ridge remains centered over W TX and a trof axis is set up over the ern CONUS. Model output continues to indicate another impulse movg sewd out of ern OK early Friday morning may bring some chances for tstms for our far nrn areas. Have maintained chance PoPs across these areas through midday, as upper impulse will be directed e of our region by the aftn. Temps likely to reach into the mid 90s Friday, as the ridge begins to extend its ewd influence in the wake of the departing trof axis. The ridge will begin to reinforce itself ewd overnight Friday night, continuing the warming trend that we began today. /12/
LONG TERM . /Saturday through Thursday/
Upper ridging will build over the region through the weekend before weakening by early next work week. Temperatures will likely warm into the mid to upper 90s. When combined with the humidity, heat index values could approach 105 degrees, which is near Heat Advisory criteria.
Mostly dry conditions expected on Saturday as the center of the ridge will settle over the region. The center will start to retrograde back into Central Texas on Sunday, putting our eastern and southern zones on the eastern periphery of the ridge. Southerly flow will return to those areas, allowing for chances for diurnal sea breeze convection to return. Current thinking is that subsidence from the ridge should keep rain chances low and limited to portions of Deep East Texas and Central Louisiana.
As we move into early next week, the upper ridge weakens and the center continues to shift westward into the SW CONUS. Low-level southerly flow will increase and sea breeze convection will form and increase in coverage during the afternoon/early evening during peak heating hours. Chances for this diurnal convection should gradually increase and spread northwest across the region as we move through the week. The increase in cloud cover from the showers and thunderstorms should cool temperatures a few degrees by next week, and possibly lower heat index values below advisory criteria. /20/

VFR conditions to prevail through the 18Z TAF pd. Can't rule out an isold shwr/tstm this aftn, but uncertainty will preclude mention attm. Light e to sely winds will become light and vrbl overnight, and generally continue through mid morning Friday. /12/

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.
