Area Forecast Discussion . UPDATED National Weather Service Jackson MS 635 PM CDT Wed Oct 28 2020

UPDATE. Updated for 00Z aviation discussion

AVIATION. 00Z TAF discussion: Deteriorating conditions can be expected this evening into the overnight as Hurricane Zeta affects HBG, PIB, MEI and GTR. In these areas heavy rain/low visibilities, low ceilings, strong/gusty winds and LLWS can be expected. Elsewhere, a strong cold front over the ArkLaTex will sweep rapidly east and through the area after midnight. Prevailings winds will switch to the west and become gusty after sunrise. While a period of VFR conditions will develop through much of the daytime, MVFR ceilings will begin spreading back in from the west by the end of the period./GG/

DISCUSSION. Through tonight .

The main story in the short term is Hurricane Zeta and its impacts on our forecast area. As of this afternoon, Zeta is located in the north central Gulf of Mexico and made landfall in southeast Louisiana this afternoon. The outer rainbands are moving across southeast Louisiana and southern Mississippi. Ahead of this, we have been getting some off and on rain showers over the area today as we remain in an airmass characterized by over 2 inch precipitable water. Zeta will continue to track to the northeast through the evening/tonight, making a second landfall along the Mississippi Gulf Coast and then moving across portions of southeast Mississippi. Not much has changed in the thinking for impacts and the main impacts to our region will be from wind gusts and heavy rainfall. Zeta is a rather small storm and impacts won't be felt very far from the center, but should also be felt more on the eastern side of the storm with a sharp gradient on the western side of the storm. As Zeta moves up the I-59 corridor, wind gusts up to 60 mph will be possible across extreme eastern Mississippi, with gusts up to 50 mph possible a little farther west.

Another concern will be from locally heavy rain. This storm will move fast but there could be 2 to 4 inch totals in the southeast, where a flash flood watch will remain, with locally higher amounts. Outside of this 1 to 2 inches will be possible. While some of this area has not seen a lot of recent rainfall, efficient rates may bring localized flooding concerns.

While not a completely zero risk, there could be some severe potential if any shower can rotate before the storm takes a more northeast turn.

Zeta will track up the I-59 corridor, or perhaps just to the east, through the evening before entering Alabama late tonight, before midnight. Once the storm moves east, conditions should improve from west to east. In its wake, the upper trough will move into the region from the west and impacting the ArkLaMiss on Thursday. /28/

Thursday through Tuesday . Zeta will quickly make its exit of the region as the day breaks on Thursday. Some breezy easterly winds will linger is its wake, along with some cloud cover. An isolated light shower can't be ruled out in the vicinity of the Highway 82, but the rest of the CWA currently looks to remain dry. Highs will Thursday will be cooler and range from the middle 50s to near 70.

A dry cold front will move through the region Thursday night. Again, other than some cloud filtering east through the CWA, no rain will accompany this frontal passage. Winds will become northerly in the front's wake, with cooler drier air advection into the area as a result. Lows Friday morning will be cool as they fall into the 40s.

Quiet weather currently looks to prevail across the entire CWA Friday through next Tuesday. Temperatures will moderate up a touch over the upcoming weekend, but pleasant conditions will still exist. Come Sunday though, a strong cold front will push east through the region. This will usher in a noticeably colder drier airmass Sunday night through the early part of the work week.

Highs Sunday will range from the mid 60s to around 70. However on Monday, they'll struggle to get out of the 50s in most locales. Then on Tuesday, they're rebound into the 60s. Lows will be quite chilly, especially Tuesday morning as good radiational cooling looks to allow lows to range from the lower 30s north to mid 30s south. If this pans out, it could result in widespread frost across locations mainly north of the Interstate 20 corridor. /19/

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.
