National Weather Service Shreveport LA 553 PM CST Sun Dec 17 2017 .AVIATION... The IFR/LIFR cigs have begun to lower early this evening, especially over SW AR/N LA, with areas of FG beginning to develop across these areas. This trend should eventually spread into E TX by mid to late evening, with all of the region likely seeing FG (some of it dense) which should linger through mid to late morning Monday. Am expecting only very slow improvements to cigs/vsbys by midday, but LIFR/IFR cigs with reduced vsbys may persist through the afternoon. Can't rule out isolated to widely sct -SHRA developing during the afternoon across portions of E TX/N LA, but low confidence precludes VCSH mention attm. Sct SHRA should begin to increase Monday night over the region as a warm front begins to shift N into E TX/N LA helping to focus this development ahead of a closed low that will begin to eject E across Nrn Old MX. Look for Lt/Vrb winds to persist through the TAF period. /15/National Ag. Weather Outlook, International Ag. Weather Summary
