(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 klix 192023 afdlix area forecast discussion national weather service new orleans la 323 pm cdt Fri jul 19 2019 Discussion A weak high pressure system is in place over our area and is expected to persist through Monday. In general, this will lead to warmer and drier conditions overall. However, southerly winds are enhancing the presence of moisture and lifting in the atmosphere. Also, upper level divergence will enhance the uplift in the atmosphere. These conditions will lead to the development of afternoon thunderstorms through Monday. Beginning Tuesday through Thursday next week, a weak low pressure frontal system is expected to move through our area. This system will likely enhance rainfall chances next week, especially Tuesday and Wednesday. The persistent southerly to southeasterly winds will enhance the lifting in the atmosphere leading up to this event. In addition, there will likely be some directional shear in the environment, enhanced by the southeasterly winds. The amount of buoyancy in the environment should also be average to high due to the enhancement of the CAPE by the abundant moisture availability. The dynamic forcing created by the frontal system will help to develop showers and storms along and ahead of the frontal forcing region. Some of these storms could be severe given the diurnal considerations, compressional heating for more efficient initiation. Main concerns will be stronger downburst winds and possible squall conditions. General model consensus shows that the front is expected to slow down and stall for a day or two near the louisiana and mississippi gulf coastlines. If this occurs, the precipitation amounts could be higher and flash flooding could be possible. More details about this possibility would be more apparent closer to the event. After Thursday of next week, the normal weather pattern is expected to dominate and conditions will return to near normal as the frontal influences diminish over time. Msw Aviation Lingering isolated convection to dissipate with sunset over the region withVFR cavok conditions expected overnight. Generally repeat of convective onset predominantly on lake breeze boundaries mainly after 17z Saturday. Rr 24 Marine Continuation of steady state onshore flow to persist for much of the |
forecast period. A weak frontal boundary is expected to stall near the coast but should have little impact aside from potentially higher thunderstorm coverage near shore by middle of next week.

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. |
