UPDATE. Updated for 12Z aviation discussion

AVIATION. 12Z TAF discussion:

Mainly MVFR conditions will exist through the day due to low CIGs around the region. RA will also impact all TAF sites through the day as rain spreads throughout region ahead of a frontal passage this evening. SHRA could result in reduced visbys. Conditions will begin to improve after 00Z when drier air begins to arrive in the region behind the front.

DISCUSSION. Today and Tonight . Rain has already started to spread into the region from the west ahead of an approaching cold front. Warm moist air will continue to advect into the region ahead of the front, resulting in above average temperatures and increasing shower activity on Saturday. Although there may be some isolated thunderstorm activity in the southern portions of ArkLaMiss today where instability could overachieve and again along the front this afternoon as it begins to finally move into the western portions of our region, no severe weather is expected. Rainfall totals should remain below one-half inch areawide, and even giving our wet antecedent conditions, it won't be enough to result in a threat of flash flooding.

As the surface front finally begins to traverse the region this evening into tonight, cold air will quickly filter in behind. MOst of the region will wake up Sunday morning to temperatures in the 30s, 35-40 degrees cooler than Saturday's highs.

Sunday through Friday . For the end of the weekend and into the first half of the work week, colder and drier conditions will be on tap. General troughing over the eastern half of the country will be reinforced by a wave diving into the Plains Sunday night. Deeper cold air will drop the high temperatures to the 40s for Monday and Tuesday, warming into the lower 50s only over the southern half of the area for Wednesday. Current 850mb temps in the 10-12C range will drop to -5C to -7C by early Tuesday morning. Near a surface ridge axis with a dry column overhead, some radiational cooling influence is expected to drop the lows to the 20s. Counter to that, the winds are expected to stay up a bit as the axis is just to the west. However, those same light north/northeasterly winds will also drop the wind chills into the teens for most of the northern half of Mississippi. High pressure ridge slips to the east during the overnight, accompanied by some mid level moisture/clouds keeping the temps from dropping too far in the light and variable winds. If that moisture does not materialize, the Wednesday morning forecast will be a bit different in the next few runs. For now, Wednesday is the beginning of a moderation in the forecast as the southerly flow returns moisture and warmth into the region. High temperatures are back to the 50s on Thursday and approaching 60 south of I-20. Next chances for precip come on Thursday/Thurs night with the next wave digging into the SW and ejecting out across the Gulf states. Major disparity between the ECMWF and the GFS with handling the energy aloft as the ECMWF splits the wave, with the weaker one to the south. The GFS is more phased, hence deeper with the developing system across the Plains by Friday morning. The current forecast is a melding of the two, with precip from Thursday afternoon through to the weekend.

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.
