NWS Huntsville, AL wrote its last area forecast discussion before the first event at Jun 17, 10:02 AM CST, 28 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Huntsville AL 1102 AM CDT FRI JUN 17 2016 .UPDATE... Morning update. && .DISCUSSION... This morning started out muggy with temps ranging in the upper 60s to upper 70s. However, temps have warmed up towards 90 degrees as of 16Z even with scattered to broken cloud cover in place ahead of the cold front. The cold front is currently draped across the TN border and will progress southward throughout the day. Showers and thunderstorms will develop along the front with convection expected to begin around 18Z. The higher chance of precip will be along and south of the TN River this afternoon with a strong to severe storm possible. The main hazard with any of the strongest storms would be damaging winds. A line from Florence to Guntersville and southward has a better chance to see a stronger storm this afternoon. This is due to the steep low-level lapse rates, plentiful CAPE, 2 inch PWATS and mid-level dry air in place ahead of the approaching cold front. HiRes models show the front moving through the forecast area fairly quickly...so adjusted the timing of today's POPs/Wx accordingly. JMS && .AVIATION... (Issued 642 AM CDT FRI JUN 17 2016) For 12Z TAFs: Mostly clear conditions this morning will give way to scattered clouds...as a cold front moves southward across the region. This boundary will bring scattered showers and thunderstorms...mainly from the late morning to late afternoon. Given discrepancies between forecast model output, did not include TSRA or VCTS for the terminals given low confidence in timing/placement of convection. The front should be south of the area by the early evening, with rain chances ending. Westerly winds in the 5-10kt range in the late morning and afternoon should become NW-N around 5kt this evening. RSB && .HUN Watches/Warnings/Advisories... AL...NONE. TN...NONE. && For more information please visit our website at weather.gov/huntsville.
