(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 kjan 171639 afdjan area forecast discussion national weather service jackson ms 1139 am cdt Sat aug 17 2019 Update Updated for 18z aviation discussion Aviation 18z TAF discussion: vfr conditions will prevail through the period. Dry weather is expected across the area, with the exception possibly being at kpib khbg. Here there could be a shower or storm this afternoon but confidence in affecting the TAF site is not high. Southerly winds will occur today around 5kts or less. Calm winds will occur overnight at most locations. No significant aviation concerns are expected. 28 Discussion Similar conditions will occur today as the ridge remains in place across the region. Pw values on the 12z kjan sounding is a little higher this morning than yesterday but still relatively dry for mid august(1.21 inches). This all will help keep showers and storms suppressed today, with some potential in the far southern part of the forecast area later this afternoon. It will be in this region where better low level moisture and flow will occur this afternoon. Temperatures today will once again be warm with highs in the mid to some upper 90s. Thankfully, with enough drier air remaining in place, this will keep heat indices mostly in check for most eastern locations. Locations in the west will see heat indices reaching 100 to 105 degrees this afternoon. 28 prior discussion below: today through tonight: the subtropical ridge will maintain relatively dry deep layer air over much of the arklamiss today with precipitable water values less than 1.5 inches at most locations helping to limit the potential for deep convection. An exception will be over northeast la into far southern ms where southerly low level flow will begin to increase this afternoon, resulting in greater moisture instability and the potential for isolated showers. In addition, the southerly flow will raise boundary layer rh, and this will cause heat stress to creep back up with a few values reaching the 100-105 range. Any showers should dissipate quickly by early this evening and quiet weather is expected to follow for the overnight. Ec Sunday through Friday: |
the forecast through the end of this week remains on track from the last few cycles. For the new week ahead, the synoptic pattern will feature a building upper-level ridge over the western central conus and weak troughing over the east coast. Better moisture returns back into our region as the old frontal boundary washes out, with pwat values mostly between 1.5 to 2.0 inches throughout the week - especially in southern parts of our area closer to the gulf coast. Flow around a weak disturbance over the eastern gulf of mexico early in the week may actually keep drier air in place just a little longer in northern parts of the arklamiss. By the end of the week, more vigorous shortwave moving across the northern tier of the u.S. Should push another front southward toward the deep south, but confidence on seeing it push too far into our forecast area is low at this time. Therefore, the chance for scattered summertime air mass showers and thunderstorms is expected areawide each afternoon through Friday. With increased humidity and the upper-level ridge in place just to our west, it still looks likely for especially northeast louisiana, far southeast arkansas, and western portions of mississippi to see peak heat index values around 105 degrees Sunday through Wednesday. Therefore will keep the limited threat area for heat stress as is in the hazardous weather outlook text and graphics. A heat advisory may be needed through the delta region at some point over the next few days, but increasing chances for showers and storms may limit heating potential.

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. |
