/issued Issued by National Weather Service New Orleans LA/ The main upper level ridge axis has shifted south and currently extends west to east across the northern portion of the Gulf. high pressure over the southeastern states was maintaining east to southeasterly surface wind flow and increasing dewpoint temperatures. With the low temperatures expected to be near the surface dewpoints, some patchy fog will be possible after midnight through about mid morning on Thursday. Highs are expected to be warm again on Thursday, generally in the lower to mid 80s.
1154 PM CDT Wed Oct 26 2016 Early-afternoon water vapor imagery revealed a de-amplifying mid- level trough from the upper Great Lakes to Ozark Plateau with an upstream ridge gradually building east through the Interior West. ridge will begin to flatten as it edges east of the Rockies, hastening the deepening of a lee trough over the High Plains. As a result, strengthening southwest low-level flow will promote notably warmer temperatures, especially across our western counties where highs will reach the mid to upper 70s.
A cold front and weak low pressure system will move through the area overnight, bringing scattered to numerous showers to the area. High pressure will build in tomorrow, bringing a return to dry weather through the early part of the weekend.
1224 AM EDT Thu Oct 27 2016 High pressure will prevail today.

A few showers, and maybe a rumble or two of thunder remains possible for the late night (after 2 AM) as a trough axis nears from the west. This corridor develops across eastern MS and western AL spreading northeast through northern AL into southern middle TN Thursday morning as an upper trof approaches. A cold front will be lagging behind as has been indicated in previous model runs. Little airmass change for our area is now foreseen through this process, although slightly drier air may advect into our eastern counties equating to cooler overnight lows than further west.
Temperatures will remain well above normal for the next several days as the dome of high pressure dominates the state.

An examination of data from the Key West evening radiosonde balloon confirms a slight warming and moistening of the lower troposphere, and a significant erosion of the inversion layer around 6000-7000 feet elevation. The large-scale pattern is still dominated by the deep anticyclone centered over the southeastern United States.
1041 PM EDT Wed Oct 26 2016 A narrow ridge of high pressure will build in from the west overnight and will slide off to the east on Thursday.

Clouds increasing ahead of the approaching weak cold front as expected. Chattanooga Airport, TN 59 78 55 83 / 10 20 10 10 Knoxville McGhee Tyson Airport, TN 56 76 52 78 / 10 30 10 10 Oak Ridge, TN 56 76 54 79 / 10 20 10 10 Tri Cities Airport, TN 47 71 49 74 / 0 30 20 0.
Low pressure was in northwest Scott county IA and continued to track east near Interstate 80. Isolated showers were located in our far eastern counties, with an area of light rain/drizzle north and west of the low. Skies were sunny in the western/southern Plains associated with a high pressure ridge, and readings there were in 70s to lower 80s. Late tonight, our far sw cwa should see a decrease in clouds as high pressure begins nosing into that area. Minimum temperatures will drop into the lower to mid 40s at most locations. Thursday: High pressure will push into the cwa so skies will gradually become mostly sunny from southwest to northeast, as the upper level trough (cyclonic flow) shifts off to our northeast.
