Area Forecast Discussion National Weather Service Shreveport LA 136 AM CDT Sat Jun 20 2026 ...New DISCUSSION, AVIATION, SPOTTER INFORMATION STATEMENT... .KEY MESSAGES... Issued at 1240 AM CDT Sat Jun 20 2026 - The expected weak upper low is on approach and will ease over our Four-State area early and move out by around lunchtime. - So one last cooler day for all, but lower 90s will return with less rain and more sun for Father's Day with breezy SW winds. - Early next week remains warm with another weak front to our north and then another upper level impulse on the light NW flow will arrive for midweek. && .DISCUSSION... Issued at 1240 AM CDT Sat Jun 20 2026 Overcast skies reside for us early this morning with our weak cold front draped over deep east TX, Toledo Bend country and NE LA. This boundary separates the lower 70s dew points from the richer mid to upper 70s in Ruston and Monroe with showers in their vicinities. Surface winds generally prevail from the NE as expected this time last night. However, the recent quiet and rainfree period from Texarkana to Shreveport and Natchitoches is going to see widespread light shower arriving shortly from E TX, where coverage is mounting over the last few hours. A weak vort continues dropping south over Red River Co. now and can be seen in the reflectivity. This lines up well under the weakness aloft at 587dam with drier air in trail. The light NW flow will be pushing this feature to the SE over the next 12 hours. So far, the enhancements of clouds elements with lightning have diminished along I-20 east, but we see a renewed potential as the low level winds from the SE feed the vort with richer moisture over E TX. So, isolated to eventually scattered to maybe numerous thunderstorm may accompany this upper low through about noon. The SPC has our Risk at General, having been worked over early today and keeping clouds for much of the afternoon. We still have a good PWAT at KSHV and hopefully some more needed rainfall for many locales. The WPC has much of our area in a Slight Risk for excessive rainfall for E TX and all of LA and extreme S AR due to slow movement primarily. The low level SE winds will work down to the surface early today and further veer flow from the S and eventually SW for Sunday. This along with more sunshine will boost the temperatures back to average for Father's Day with the official start of Summer right on queue. The Summer solstice occurs as most of us sleep at 3:24 a.m. early Sunday morning. It will be warm and humid to begin the new season with Heat index looking to be in check for most us holding around that 105 threshold. The chance for rain will linger with diminished coverage for both Sunday and Monday and an uptick Tuesday and Wednesday with our next weaker cool front and repeat upper level disturbance combo riding down across the area during Wednesday. Coverage will slip away again to end the week, but still remain active diurnally with lower 90s. Then, the next set of surface and upper lows will be riding on a track just a little farther north with less coverage south of I-20 to put a bow on June rain bucket totals. The CPC 8-14 day outlook is for slightly above temperatures in the low to mid 90s and near normal rainfall as we prepare to celebrate our Great Nation's semiquincentennial birthday on July 4th. /24/ && .AVIATION... (06Z TAFS) Issued at 1240 AM CDT Sat Jun 20 2026 Areas of -SHRA have begun to develop across E TX/adjacent SW AR and portions of N LA, ahead of a weak upper level trough that will drift E into the region through the morning. MVFR cigs have also begun to develop especially N of I-20 across NE TX/SW AR, with additional MVFR cigs expected to develop elsewhere overnight especially as the convection continues to deepen and expand E across the region. Have tempoed in thunder and reduced vsby mention across the area terminals to account for any embedded TSRA, with the convection expected to slowly drift ESE across the region through much of the morning before diminishing by midday. Thus, the low cigs should linger through a better part of the morning, before eventually scattering out once the convection diminishes. The LFK/ELD/MLU terminals should be the last to clear the convection, with a scattered cu field and residual elevated cigs persisting through the afternoon before thinning by/shortly after 00Z. VFR conditions will continue through the remainder of the TAF period, although low MVFR/IFR cigs should redevelop and spread N into the area prior to daybreak Sunday. Lt ENE or Lt/Vrb winds overnight will eventually become S 5-8kts after 15Z. /15/ && .SPOTTER INFORMATION STATEMENT... Issued at 1240 AM CDT Sat Jun 20 2026 Spotter activation may be needed early today with the focus for the day along and south of I-20. && .PRELIMINARY POINT TEMPS/POPS...
