FXUS64 KSHV 091719 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1219 PM CDT Thu Jul 9 2026 ...New DISCUSSION... .KEY MESSAGES... Issued at 1209 PM CDT Thu Jul 9 2026 - High humidity values combined with highs in the low to middle 90s will result in heat indices above 105 degrees for portions of northeast Texas, southeast Oklahoma, and southwest Arkansas this afternoon. A Heat Advisory will be in effect from noon through 8 PM. - Quiet and dry weather will continue through the end of the week, with areawide highs in the low to middle 90s. - Showers and storms are expected to return this weekend, continuing through midweek. && .DISCUSSION... Issued at 1142 AM CDT Thu Jul 9 2026 The ArkLaTex is sandwiched between an upper-ridge extending from southern California eastward into Texas and a weak trough across the Texas coast into north Louisiana and Mississippi. The ridge will allow for sufficient subsidence to drive temperatures into the mid 90s this afternoon across the ArkLaTex. Dewpoint values may be slow to mix across the I-30 corridor allowing for afternoon heat index values to exceed 105 degrees this afternoon. Thus a Heat Advisory is in effect from noon through 8 PM. Otherwise, the upper-trough may allow for enough instability to spark a few showers and thunderstorms across portions of north Louisiana this afternoon. Upper-trough across the northern gulf to gradually lift north on Friday allowing for convection to develop along the seabreeze boundary with a few showers and thunderstorms possible across portions of Deep East Texas and north Louisiana. On Saturday, the lingering upper-trough across the mid-Mississippi River valley becomes more dominant across the ArkLaTex. Instability associated with the trough combined with a northward surge of moisture from a weakness in the Gulf of America will lead to increasing rain chances areawide. Upper-level high pressure to become firmly established across the northern plains late in the weekend into early next week bringing an easterly upper-flow pattern to the ArkLaTex. An area of low pressure is forecast to retrograde along the southern periphery of the ridge across the Ohio River Valley into Arkansas and eventually into Texas and Oklahoma by midweek allowing for an unsettled weather pattern characterized by periods of widespread rain each day. The added instability will also provide sufficient mixing to limit afternoon temperatures to the upper 80s to lower 90s. /05/ && .AVIATION... (12Z TAFS) Issued at 451 AM CDT Thu Jul 9 2026 VFR conditions prevailing just before sunrise this morning and those conditions should continue through the daytime hours and overnight tonight as well. Just some thin cirrus being observed across the eastern half of our airspace, remnants of late night convection across SC/SE AR. Should see developing cu field through the day across our airspace but we shouldn't have to deal with much if any convection unlike previous days. Stronger low level pressure gradient in place today which should result in SSE to SSW winds sustained near 10kts areawide with some stronger gusts possible across our NE TX terminals. 13 && .SPOTTER INFORMATION STATEMENT...
