Area forecast discussion, Jun 30, 6:20 PM CDT, 3 hours 30 minutes before
Area Forecast Discussion National Weather Service Lubbock TX 620 PM CDT Tue Jun 30 2026 ...New AVIATION... .KEY MESSAGES... Updated at 615 PM CDT Tue Jun 30 2026 - Scattered thunderstorms remain expected today, generally along and west of I-27. A few storms may become severe. - Storm chances continue Wednesday evening. - Hot and dry conditions will prevail late in the week and into the weekend, followed by a slight cooldown with overnight rain chances. && .SHORT TERM... (This afternoon through Wednesday) Issued at 1157 AM CDT Tue Jun 30 2026 An upper trough continues to pivot across the west while a strong upper ridge remains in place over the eastern US. A southerly plume of moisture will again be advected into the region through the afternoon. The pattern looks almost identical as yesterday with much of the shortwave activity and low-level wind shear ahead of the aforementioned trough not occurring until the evening hours. CAMs again indicate convective development near the TX/NM border before gradually moving northeastward through the evening. Much of it should remain along and west of I-27 where the greatest forcing and moisture parameters will be present. A few storms could become severe producing strong winds and up to quarter sized hail. These should taper off by early Wednesday morning. Mostly cloudy skies and elevated southerly winds will keep lows mild overnight, ranging from the mid 60s to mid 70s. Subtle upper height falls during the day as the ridge to the east weakens will bring highs down to near 90 on the Caprock, however highs off the Caprock will remain in the mid-to- upper 90s. && .LONG TERM... (Wednesday night through next Monday) Issued at 1157 AM CDT Tue Jun 30 2026 Isolated thunderstorms will be possible Wednesday night into Thursday morning as daytime heating and moisture will allow for some convective initiation, mostly in the western half of the forecast area. Following this, rising height values associated with the high pressure system to our east will gradually increase high temperatures and decrease humidity throughout the week and into the weekend, with temperatures in the high 90s and dry conditions expected on the 4th of July. Temperatures will decrease slightly post-Independence day, but still remain well into the 90s each afternoon. There exists a chance for overnight showers early next week, though the amount of rain is uncertain. && .AVIATION... (00Z TAFS) Issued at 615 PM CDT Tue Jun 30 2026 VFR conditions are expected to continue at all TAF sites through the period. VCTS will impact KLBB and KPVW through the evening, with chances for scattered -TSRA by late tonight, decreasing in coverage through the early morning hours. There is some indication that low stratus may develop just south of the KLBB terminal around daybreak, however confidence remains far too low at this time for a TAF mention. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM...19 LONG TERM....RMS AVIATION...12
