Area Forecast Discussion National Weather Service New Orleans LA 1208 AM CDT Tue Jul 14 2020

UPDATE. updated for 06z taf issuance.

PREV DISCUSSION. /issued 431 PM CDT Mon Jul 13 2020/

SHORT TERM.

Coverage of isolated to scattered showers and thunderstorms finally developed as expected this afternoon which is breaking the heat in some areas. The Excessive Heat Warning and Heat Advisory were still validated however with heat index readings rising to 108 to 115 in most locations. A few storms the remainder of this afternoon and early this evening could still pulse up to strong to marginally severe levels with wind gusts over 40 mph possible along with a few locations with torrential downpours and minor flooding.

The pattern will be evolving from a dominant mid/upper high across the southwest/south central states to an elongated high across the entire southern U.S. tier with a general weakness/small scale, stalled shortwave trough over the central Gulf coast region by mid week. Tomorrow will still be warmer than normal with high enough humidity levels to produce heat index readings of 108 or higher, so a Heat Advisory has been issued valid from 10 am to 8 pm. Like today, the lucky areas that see the isolated to scattered showers and thunderstorms will have a shorter duration of high heat indices, however those that don't get rain will keep the miserable conditions around longer.

Not much change is noted Wednesday into Thursday, however the 12z model runs today really increased the PoPs today, while the NBM and official NWS forecast are a bit more conservative raising the rain chances and lower temperatures (keeping it hotter).

LONG TERM.

Friday through next Monday has a greater uncertainty today, as some models indicate a continental mid/upper high to our north dominating and keeping the area relatively dry, while some other models indicate a tropical connection developing form the easterlies and at least weak wave/inverted trough features moving east to west across the Gulf of Mexico. Have a fairly seasonal forecast Friday through the weekend with scattered mainly afternoon showers and thunderstorms before going back up to 50 to 60% rain chances on Monday. Temperatures should be closer to seasonal normals.

AVIATION. VFR conditions are expected at terminals outside of any thunderstorms that directly impacts one, with the best timing being late morning and early afternoon. For any storms that form could have gusty winds and reduced visibilities. -BL

MARINE.

A few showers and thunderstorms, some with strong gusty winds, are expected to impact the tidal lakes, sounds and at least nearshore coastal waters at times for the next week. Otherwise, relatively light to at times moderate winds and low seas expected outside of convection.

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.
