Area Forecast Discussion National Weather Service Jackson MS 532 AM CDT Thu Oct 1 2020

UPDATE. Updated for 12Z aviation discussion

AVIATION. 12Z TAF discussion:

VFR conditions will prevail at all terminals through the TAF period. A dry cold front will move through the are today with northerly winds around 7-10kts. A few isolated gusts up to 15kts cannot be ruled out at any given location. /TW/

DISCUSSION. Today and tonight: An amplified synoptic pattern will remain in place with stout ridging across the Great Basin and a downstream mean longwave trough. The CWA will be just west of the trough axis with northwest flow aloft over the Lower Mississippi Valley. A dry cold front dropping out of the Great Plains will move through the area today with dew points dropping into the low 40s by tomorrow morning. High temperatures today will range from the mid to upper 70s north of I- 20 to the low 80s along and south of I-20. Overnight lows will drop into the upper 40s north and low 50s south. The sprawling surface high will remain centered over the Great Plains tonight and as such will keep a tighter pressure gradient in place across the region. Resulting 5-7kt winds will keep the boundary layer mixed and will preclude efficient radiational cooling and colder low temperatures. /TW/

Friday through Wednesday: Broad mid level trough looks to remain over the eastern three fourths of the country through the period with ridge remaining in the west. At the surface, high pressure axis remains across the area. By Saturday, a mid level shortwave and associated surface cold front will move from the central into the Southern Plains. Though surface dewpoints in advance of the front will be in the 50s, enough convergence along the front will lead to shower development over the ArkLaTex Saturday evening. As the shortwave kicks east Sunday, weaker frontal forcing and weaker overall flow in advance will make it difficult for shower development though some slight chances will still exist over the ArkLaMiss Delta region Sunday morning. Beyond that, no appreciable systems look to impact the area as surface high pressure maintains control and keeps higher dewpoints/moisture penned up along the coast./GG/

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
