Area Forecast Discussion National Weather Service Little Rock AR 616 AM CDT Sun Aug 9 2020

AVIATION. High pressure will dominate across the region today with virtually no chance of precipitation. Light southerly winds continue to bring moisture into the area and this has resulted in some fog, especially at KADF where LIFR conditions persist. Any and all fog is expected to dissipate early this morning with VFR conditions expected for the remainder of the period.

PREV DISCUSSION. (ISSUED 336 AM CDT Sun Aug 9 2020) Short term . Today through Monday night

Conditions across the state this morning are starting off much more representative of August than the past few mornings with both dew points and temperatures in the 70s. Latest surface analysis places the center of upper level high pressure over the Arklatex and it will be remaining pretty much in place through the period.

The resulting sensible weather will be temperatures a few degrees above normal with plenty of humidity as well. Heat index values do briefly touch advisory criteria in a few spots this afternoon, for an hour or two, but spotty coverage does not warrant any heat related headlines for today. Heat index values of 105 degrees look a bit more widespread for Monday but enough uncertainties exist to push off that decision for the time being.

Concerning precipitation, a shortwave located over eastern Missouri this morning will slide to the northeast of the state without any fanfare. Widespread subsidence will bring a dry day across the state today with even afternoon cumulus hard to come by. Meanwhile, a cold front and associated shortwave trough will be dropping down from the north Monday night and into early Tuesday, knocking down the ridge just a bit. This approaching system will produce scattered showers and thunderstorms to round out the short term period with the best chances along the Arkansas/Missouri border.

Long term . Tuesday through Saturday night

A shortwave trough will be progressing Ewrd across the Nrn portion of the state in the beginning of the long term period. As the perturbation ejects, widespread PoPs will be possible through Tues afternoon and evening, including showers and a few thunderstorms, but no severe weather is anticipated.

By mid week, Wrn CONUS ridging will expand Ewrd, with a broad upper lvl anticyclone centered over the desert S/W. With AR on the N/E periphery of the upper high, several small perturbations are fcst to traverse through the flow. This will keep Chc PoPs in the fcst on a daily occurrence for much of the state, but most precip will likely consist of diurnally driven showers/thunderstorms. Through the period, temperatures will remain near normal values, with high temps in the low to mid 90s and heat index values approaching the century mark most afternoons.

LZK Watches/Warnings/Advisories. NONE.

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.
