National Weather Service Shreveport LA 500 AM CDT Sun Oct 21 2018 .SHORT TERM.../Sunday through Monday/ Beautiful fall morning with plenty of dew around with the wet soil peculating into the air despite some decent wind speeds for the predawn hours. There are a few sheltered calm spots in OK/AR with the coldest readings in the middle 40s and quite foggy conditions such as DeQueen. The I-20 corridor and Southward are still in the low to mid 50s. Dew points are running a 3 to 5 degree spread in the wind and that usually limits dew formation. High pressure fresh out of Canada is edging into MO with 1030mb. The winds will continue to bring in cold air with some gusts possible. Our VAD wind profiler is running 35KT at 1kft and 45KT at 2kft. So this will keep a chill in the air this morning. Highs today will be well below average for late Oct. with low to mid 60s. These will occur late in the afternoon once the air mass is closer in and sprawls out a bit over the mid-South and OH valley. This will make for a much colder night tomorrow as the pressure gradient drops off areawide to near calm for daybreak Monday with a solid 1024mb contour wrapping the cwa. We are looking 10-15 degrees colder to start the day with patchy frost along with the dew, mainly in the lower elevations along the Hwy 82 corridor with mid 30s expected, elsewhere we will be around 41 degrees. Highs should be mid to upper 60s as the warming trend begins with the departing air mass. /24/ .LONG TERM.../Monday night through Sunday/ Western edge of broad surface high pressure begins to move east of MS river Monday night allowing for gradual warming trend following coolest temps of the fall season thus far. Moisture building along se TX coast in active southern stream jet, but trends are for precip to remain mostly south of area thru early Wednesday as low pressure along coast slower to develop. Low lvl winds will remain ne due to proximity of cwa relative to low along coast. Southwest flow aloft to maintain mostly cloudy skies with increased overrunning and isentropic lift. Likely pops in near saturated airmass for at least portions of area south of I-20 but may be raised areawide if models continue to show saturated air across most of area. As this coastal low moves east of area, nw flow aloft to bring dry air back into region. Deep upper trough swinging just east of area in this nw flow will only contain marginal moisture but steep lapse rates with elevated instability. Have added isold tstms ne half of cwa on Saturday with passage of trough, followed by additional cool and dry air to close out remainder of the wknd. /07/National Ag.
